Terms and Conditions of Sale

PRICES AND SHIPPING:All prices are FOB Casper, WY. We ship via UPS. Next Day early-AM delivery is available, as is Saturday delivery. Freight insurance is free up to

100.00 value, and costs 60 cents extra for every additional 100.00 of value. We ship everything insured for its full value. Orders for parts in stock willgenerally ship the same day if received before noon Mountain Standard Time. We can also ship freight collect via the carrier of your choice.

LIMITATION OF WARRANTY:The items in this catalog are designed and manufactured specifically for use in race cars. Woodward Machine Corporation does not warranty or

guarantee race car components for the following reasons, among others:

(1) The conditions of end use are normally hazardous and unpredictable, and are entirely beyond our control; and(2) The decision as to the suitability of said components for a particular manner of use, or in a particular installation, is made by the user and is

likewise beyond our control.

Liability of Woodward Machine Corporation is therefore limited to the replacement or repair, at our option, of any of our products that we find,upon our inspection, to be defective in materials or workmanship, specifically excluding items damaged as a result of collision, misuse, or neglect.

RETURNS OF MERCHANDISE:Returned parts may be subject to a charge of up to 20% to defray the cost of inspection, restocking, and repackaging. Returned merchandise must

be unused, unmarked and not over 30 days old. We will make adjustment via exchange or credit only. Customer-modified parts, special order parts,damaged or rusted parts, or basket cases are not returnable except in connection with repair orders.

SPECIAL ORDER PARTS:In this catalog, certain categories of parts are available in various lengths and sizes to fit different race cars. We offer most of these custom

variations at no extra cost. Please note, however, that some parts, if built to unusual or uncommon specifications, can be specialized enough to beotherwise unsalable. Such items require prepayment and are not returnable.

REPAIR SERVICES:We can usually rebuild an old rack and pinion to a functionally new condition for less than the cost of a new unit, provided its major components

are salvageable. In the case of a wrecked unit, a reasonably careful cleaning and boots-off inspection before sending it in will often reveal the extent ofthe damage, and may save the customer the trouble and expense of packing and shipping it to the factory. Basic (i.e. non-crash) rebuilds qualify for a flatrate which includes parts and labor. Crash rebuilds usually have to be quoted after inspection.

Weld repair of impact craters at the ends of the rack housing is usually possible and we do it regularly. Material ground off the bottom fromcontact with pavement is in a relatively unstressed area and can be ignored unless it has actually gone all the way through. The following items, however,are not repairable: (1) grinding in the juncture of the pinion boss and the mounting pads; (2) grinding into the snubber threads; and (3) grinding into thetop of the housing. Please note that if the customer has ground or machined material from these areas of the housing for clearance, it may be structurallyweakened and unsafe for reuse.

When sending something for repair, always use UPS or FedEx so its progress can be tracked. With UPS, freight insurance is free up to 100.00 value,and costs 60 cents extra for every additional 100.00 of value. Always insure your equipment for what it would cost you to replace it. If UPS should loseyour insured package they will settle your claim promptly. IMPORTANT: DO NOT SHIP YOUR PARCEL VIA US POSTAL SERVICE. At present, the USPostal Service does not deliver to street addresses in our area, so it cannot come directly to our plant. It may be rerouted to our PO Box, which adds somedelay, or it may be returned to you. We have no way to track incoming Postal Service freight and will not even know you sent it until we receive a noticein the mail. Also, experience has shown that if you do send it via US Postal Service, and it gets lost or damaged or simply remains undelivered, you willfind it very difficult and time-consuming to obtain compensation.

PROPER PACKAGING will ensure that your items arrive here with no more damage than they originally sustained on the race track. Cushion theparts firmly, and protect any protruding shaft ends from puncturing the carton. Do not put heavy objects into a carton loose, or with nothing betweenthem but styrofoam pellets. Servos, cylinders, hoses, and the like should be drained, plugged, and sealed in plastic wrap, or they will soak the carton,possibly causing the label to come off in transit or the parcel to disintegrate. Please put a note inside the carton describing the problem, and include adaytime phone number so that we can call you with an estimated cost.

2009 Engineering Changes

Rack type recognitionBeginning in 2008, Woodward racks underwent a comprehensive redesign. Because almost every detail of our racks was re-engineered and

improved, almost none of the internal parts are interchangeable between the former types G/H, and the present type GE/HE. The following pages showthe individual parts in their old and new versions. While bearing/seal kits and some parts are still available for the older racks, no old-style parts will bemanufactured after existing stock is depleted. To provide maximum service to our customers during this transition period, old racks sent for rebuild willbe eligible for upgrade to the new design at a heavy discount. The illustration below points out the readily identifiable external features which distinguishthe new HE rack from the old H rack:

2000 PSI PTFE hose with permanent ends

Housing accepts large-bore G150C cylinder

Rod bracket is shorter

Servo mounted with six 10-24 bolts

Lighter-section ribbed casting

Cylinder is closer to rack

Grease fitting on near side

Servo mounted with three 1/4-20 bolts

Please note that improvements and new features are being introduced as time permits. Not all current features or options are shown in the aboveillustration, but most are. Other Woodward rack types have also been updated or superseded by new designs, and these changes are shown in theirrespective sections of the catalog.

GE/HE100G100GE/HE housing replaces both G and H

The former H rack, with its mounting provision for directmounting of the servo, was distinct from the former type G whichhad no such provision and could be used only with an inline orremote servo. The new GE/HE rack housing can be used eitherway. When built as a type GE the servo mounting holes havebolts installed in them to exclude dirt. Except for the bolt hole atthe upper left, which goes through to the interior, these bolts canbe discarded and the cast boss cut or ground off if desired. How-ever, leaving the mounting provision in place enables a GE rackto be converted to an HE at a later time by adding the servoadapter.

GE/HE100 H100

Specific-ratio machiningA five-axis machining process specifically

locates the pinion bore for each ratio. The old de-sign used a large assortment of eccentric bearingcaps to accommodate different pinions, and waslimited to a very coarse adjustment. The new capshave a very small eccentricity which allows thegear backlash to be set to virtually zero while pre-serving free conjugate action, and eliminating anyneed for drag-producing preload.

All-ball-bearing pinionThe new pinions are supported by THREE ball bearings for in-

creased radial load capacity and reduced friction. This feature addssignificantly to the useful life of the rack, since pinion bushing wearand eventual misalignment of the gear teeth is completely eliminated.The stacked pair of ball bearings used to resist thrust loads was proveneffective over many years and has been retained in the new design. Anew lip seal to exclude dirt and pressure-washer fluid replaces the o-ring formerly used .

More compact designComputer-designed material distribution has greatly increased

the stiffness and load-carrying ability of the new housing while offer-ing an extra .25 inch of usable rack travel over the previous type Gand H housings. The grease fitting has also been relocated for im-proved access in the car. The pinion area now packs 50% greater ball-bearing capacity into a shorter space and allows the cylinder to bemounted closer to the rack without compromising the alignment ofthe pinion with the steering shaft.


G170piston rod (old)

GE170piston rod (new)


Improved CylinderThe assist cylinder has also undergone a minor change to take advan-

tage of the new housing. Because the type GE/HE housing is more compactlengthwise, it provides approximately 1/4 inch greater usable rack travel whencountersteering to the right than was possible with the former type G and H.

Installing an older G150B cylinder on a new design rack will interferewith rack travel to the left and should have its old design G170 piston rodchanged out for a GE170.

The GE150B cylinder (or a G150B converted with a new piston rod)can be made backward-compatible with old racks by adding a .25 inch stack ofwashers between the rod and the bracket.

The GE150C large-bore cylinder is standard on the 4.19 and 4.45 racksand optional on slower ratios, but will NOT fit older racks.

GE264 (new)

G264 (old)

New Rod BracketMoving the cylinder closer to the rack has resulted in a shorter

and stiffer rod bracket capable of transferring the full force of thelarge-bore cylinder at maximum pump pressure without deflection.Its failure threshold has been raised by the addition of a very hightensile (200,000 PSI) bolt manufactured by ARP. This bolt is avail-able with replacement old-style G264 rod brackets on special order.

Lightweight Pressure HoseWe have replaced the previous 1500 PSI hydraulic hose and reusable

ends with PTFE core 2000 PSI hose and permanent ends, for lighter weight andimproved flow. All hose end fittings are manufactured by Woodward.

Guide to Rack Part Numbers

New part numbering systemOur part numbers have been expanded to include as many useful details as possible. Virtually any option can be specified using the codes shown

above. Certain rack types are available with extra options, such as the GE/HE series which can be provided with a special rackshaft with two right-sidetie rod holes for use on chassis with interchangeable mounting positions for the right-side upper and lower control arms. For example, part numberGE366CC-1825/1925-955-210 would be an otherwise standard 18.25 rack but with an extra tie rod hole located one inch outboard on the right. Anothercombined number is used in the GL/HL series, where frequently the rack travel must be limited to less than the standard 6 inches. If, for example, a 25inch rack is required to have 5 inches travel, this is done by installing a 25 inch rackshaft in a housing ordinarily used for a 26 inch rackshaft. The partnumber for such a rack and pinion might be HLM209X-2500/2600-850-2-215.

Certain rack series (notably the GL/HL, MR, MRC and MC) consist largely of custom designs, and can therefore have more possible part numbersthan will fit on a catalog page. Although nominally built to order, GL/HL racks are offered in standard length increments and these are shown in all theirpermutations in the Master Price List. MR, MRC and MC racks, however, are subject to practically infinite dimensional variations and are assignedindividual model numbers during the design stage.

Rack and Pinion Steering

Type GE Manual Racks (ratios from 2.09 through 3.14 inches per turn)General purpose manual steering applications

One-piece housing with heavy-duty rackshaft and all-ball-bearing pinion, available in three tie-rod styles.

shown:GE262X-1825

Ratios quicker than 3.14 inches per turn, although available on special order,are not shown as standard because they are not generally practical without powerassist. The former extra-slow ratios of 1.83 and 1.57 have been discontinued.

The housing is machined for later conversion to power steering. Racks withstandard or monoball rack ends can be equipped for power-assisted operation by bolt-ing on a servo, a cylinder, and the appropriate rod bracket. Other parts required arepump, reservoir and hoses. See the Power Steering Components section for details.

Type GE Power Racks (ratios from 2.09 through 3.14 inches per turn)Power steering with inline servo, paved oval track applications

With power steering, the physical effort of steering is independent of the gear ratio; therefore, it is usually possible to use much quicker steeringthan with a plain manual unit. The servo has a splined input and output and can be installed anywhere in the steering column. The servo case does nothave to be mounted to the chassis, provided at least one end is rigidly coupled into the steering shaft. The High Load Option is recommended for chassissetups using extreme anti-dive/caster gain or quicker steering ratios.

Type HE Power Racks (ratios from 2.09 through 3.14 inches per turn)Power steering with integral servo, paved oval track applications

These units have the servo mounted directly to the rack. This arrangement eliminates the extra u-joint and coupler used with an inline servo, anduses shorter hoses. The servo can be rotated for hose clearance. When ordering, specify the ratio and rack length (e.g. HE262CB-1825) and the servovalve and valve torsion bar (e.g. 855-205). The High Load Option is recommended for chassis setups using anti-dive/extreme caster gain or quicksteering. Note: Many pavement race cars use a left-side block-mounted dry-sump pump which crowds the area of the servo. In cases of interference, theservo can be easily separated from the rack and mounted inline without any loss of function.

The servo has a splined input and output and can be installed anywhere in the steering column. The servo case does not have to be mounted to thechassis, provided at least one end is rigidly coupled into the steering shaft. The High Load Option is recommended for chassis setups using extreme anti-dive/caster gain, or where mechanical leverage is lacking due to spindles with short steering arms. The most popular ratio in this group is the 3.66; theslower ratios were at one time used in late models practically everywhere but are now used mainly for limiteds or on cars running exclusively on largerrace tracks. If your steering requirements are unknown, call us for a recommendation.

Type HE Power Racks (ratios from 3.14 through 3.92 inches per turn)Power steering with integral servo, dirt oval track applications

Like their paved-track counterparts, hese units have the servo rigidly attached to the rack with six bolts. Note: The crossmembers on someexisting dirt late models may interfere with these bolts. While a double-tube crossmember can easily be modified for the necessary clearance andreinforced with a backup gusset, it is generally not practical to do this on a single round tube. In such cases the rack and servo can be separated andinstalled as an inline setup, which is functionally identical. Some chassis are now being built with a crossmember specifically designed to accept this rackwithout interference; if you are considering a new car, call us for recommendations. Chassis setups using extreme front anti-dive (caster gain) and/orshort steering arms may need the High Load Option.

MONOBALL rack ends and the appropriate rod bracket can be furnishedwith any power rack on a custom order basis. Because of their 52 degreeoperating range, monoballs are useful in cases where standard rod endsare reaching their misalignment limit and causing a mechanical bind.

Note: The freer action of monoballs usually lowers the steering resistanceenough to require installing a stiffer torsion bar in the servo.

Type HE Power Racks (ratios 4.19 and 4.45 inches per turn)Super-quick power steering with integral servo, dirt oval track applications

The 3.92, 4.19 and 4.45 ratios are equipped standard with the High Load Option. The larger internal porting of the 900 series servo is designedspecifically for the unrestricted flow needed to power the larger-bore cylinder at the higher velocities of these racks. Note: These racks require a constantpump volume of at least 3 GPM (12 liters/min). Also, because steering ratios of four inches per turn and up have a severely reduced mechanicaladvantage, pumps used with these racks should be equipped with a pressure relief setting of 1450 PSI (100 bars). Use of a Woodward de-aeratingreservoir with a -8 return line and the -12 pump intake kit is highly recomended to prevent overheating (see the Power Steering Components section fordetails of these accessories).

Type GE Power Racks (ratios 4.19 and 4.45 inches per turn)Super-quick power steering with inline servo, dirt oval track applications

Functionally identical to the HE Super-Quick rack, the GE Super-quick has a separate servo intended for installion at any convenient point alongthe steering column. The servo case does not have to be mounted to the chassis, provided at least one end is rigidly coupled into the steering shaft. TheHigh Load Option is standard on the 4.19 and 4.45 ratios. Because steering this quick has a severely reduced mechanical advantage, pumps used withthese racks must be capable of supplying at least 3 GPM and should be equipped with a 1450 PSI relief setting. The oversize -12 pump intake kit is alsorecommended.

Type GL Manual Racks (2.09-3.14 ratios)Longer length manual steering applications

Designed to accommodate the longer rack lengths typical of GT race cars, the housing is made to support the rackshaft proportional to its length,with no more overhang than necessary for the required rack travel. Mounting dimensions for all GL/HL racks can be found in the Technical Referencesection. The type GL uses the newer internal parts of the GE/HE, such as the all-ball-bearing pinion, and has replaced the former type K. Although theycan be supplied on special order, ratios quicker than 3.14 are not listed since these are generally not practical to use without power assist, and the formerextra-slow ratios of 1.38 and 1.57 have been discontinued. Manual racks are available in all three tie-rod styles.

For manual steering purposes, monoball rack ends are byfar the preferred style. They promote easier steering because theydo not impose offset loads.

The type GL can be converted for power assisted opera-tion by bolting on either the G150B or G150C cylinder, as well aseither the 800 or 900 series servo. Direct servo attachment wasnot possible with the K series. The two-bolt rack mountingmethod, besides providing clearance for an integral servo, is muchmore fabricator-friendly than the former type K with its verticalbulkhead mount. With a GL, chassis bracketry can be as simpleas a pair of tabs with 1/2 inch holes.

Engineering improvements from type KThe four 3/8 holes of the type K are replaced with two 1/2 holes with

the pinion angled upward 15 degrees from the mounting plane. Viewed fromabove, the pinion is angled away from center at 20 degrees instead of 12.

Type GL Power Racks (ratios from 2.09 through 3.14 inches per turn)Power steering with inline servo, road racing and custom car applications

As with the manual GL racks, the housing is made to support the rackshaft proportional to its length, with no more overhang than necessary forthe required rack travel. Ratios quicker than 3.14 are not commonly used in the applications of these racks and are not listed as standard; however, sincepower assist removes any mechanical obstacle, ratios up to 4.45 are available on special order. The former extra-slow ratios of 1.38 and 1.57 have beendiscontinued. The GL is intended to replace the former KC rack with minor refabrication of the mounts on the chassis.

Type HL Power Racks (ratios from 2.09 through 3.14 inches per turn)Power steering with integral servo, road racing and custom car applications

These units have the servo mounted directly to the rack. The servo can be rotated for hose clearance. The High Load Option is recommended forheavier cars (above 2400 lb/1100kg) or for special-order quicker ratios. In cases of component interference, the servo can be easily separated from therack and mounted inline. The HL rack is functionally identical to the GL, but the integral-servo configuration eliminates the extra u-joint and couplerneeded with an inline servo.

Type MR Power RacksPower steering with integral cylinder and servo, for road racing and proprietary supercars

For installations requiring relatively long pivot centers. Vastly lighter in weight than any production-car power rack, the minimum length possibleto build depends on the rack stroke and the pinion location. MR racks can be built as left or right hand, front or rear steer, offset or centered, in tworatios2.02 and 2.24 inches/rev (51 and 57 mm/rev) and with a maximum stroke of 5.38 inches. In most MR applications the steering arms on the hubcarriers are fairly short, and the rack travel will rarely exceed 4.5 inches. The MR mounts in clamp brackets and can be oriented to any angle.

A tapped bolt circle on the end ofthe servo provides a rigid and convenientthird mounting point. In most cases therack velocity is low enough that an elec-tric power steering pump can be used.Options include mounting provisions fordata acquisition equipment and addi-tional weight reduction by gundrillingthe rack shaft. Many variations are pos-sible, a few of which are shown at left.

To obtain a design proposal anda quote please specify the following de-tails so we can determinewhether onecan be manufactured to fit your appli-cation:

(1) Pivot center distance(2) Total rack travel required L to R(3) Ratio (rack travel per revolution)(4) Pinion location relative to center(5) Front or rear steer (i.e. whether therack is to be located ahead of or behindthe front wheels)

Other information about the carcan be very helpful in determining therequired level of power assist. If the ve-hicle is an early-stage prototype and itscharacteristics are unknown, we suggestthe prototype rack be ordered with arange of servo valve components to al-low substitution during track testing.

Please bear in mind that not alldimensional combinations are possible.For example, the MR rack has an inte-gral hydraulic cylinder which obviouslycannot occupy the same space as the rackteeth. What is often overlooked is thatboth of these elements must move thefull length of the rack travel without mu-tual interference. This fact imposes adefinite minimum on the length of therack housing, which dictates a minimumlength for the rackshaft, which in turnmust protrude from the housing at eachend by a distance equal to half the travel.

It will be seen that the mountingpoints on MR racks are located at theextreme ends of the housing tubes so asto obtain the minimum possible rackshaft overhang and the maximum sta-bility. This feature is essential in extract-ing the maximum efficiency from suchan extremely lightweight unit.

In cases where a power rack mustbe made especially short, it is sometimespossible to mount an external cylinderparallel to the rack, as shown at left.

Type MRC Power RacksPower steering with integral cylinder and inline servo, same applications as MR series

For type MR applications where severe space conflicts exist in the area of the pinion housing such as in front-engined race cars. MRC racks use themuch smaller housing of the MC manual rack. With this setup the servo is mounted independently and is connected to the pinion through an intermediateshaft and/or universal joints. Like the MR, these racks can be made left or right hand, front or rear steer, offset or centered, with a maximum stroke of 5.38inches. While functionally identical to the integral-servo MR, separating the servo from the pinion removes some dimensional constraints and inciden-tally enables the use of some additional gear ratios. Although there are no functional limitations on its distance from the rack, it is important not to mountthe servo within the drivers compartment in a way that could directly expose the driver to the radiant heat of operation or to hot fluid.

Type MC Manual RacksManual steering for lightweight formula cars, dragsters, LSR cars, FSAE projects

The MC rack uses the same mounting clamps as the power racks as well as the same clevises. Like the power racks, the mounting points arelocated a fixed distance from the ends of the housing, which is calculated to result in the minimum possible shaft overhang and the greatest tie-rodstability. Completely modular in design, most MC configurations are available virtually off the shelf except for the rackshaft itself which must becustom made according to length and number of teeth required. Like all Woodward racks these units have the .750-20 pinion spline, which provides asubstantially more positive engagement than the .562-36 usually found on small steering racks. To achieve equivalent light weight, the pinion is hollow.

All units not requiring machiningmodifications to the housing (e.g.radical offsets) are priced the same.MC .................................... 645.00

In order to quote an MRC rack we musthave the following information:


When considering the MRC de-sign, please bear in mind that not all di-mensional combinations are possible.Like the MR, the MRC has an integralhydraulic cylinder which cannot occupythe same space as the rack teeth, andthe same stackup of dimensions willinfluence the length of the housing. How-ever, the smaller pinion housing of theMRC rack usually permits offsetting thepinion somewhat farther to one side thanis possible with the MR, all other thingsbeing equal.
