COMPANY PROFILE

Reyco Granning Suspensions was formed by the merger and acquisition of two well-known names in the heavy-duty vehicle suspension industry: Reyco and Granning.

Reyco grew out of the Reynolds Mfg. Co. and was first known as a major supplier of brake drums for heavy-duty vehicles, and later developed a full line of air and steel springs suspensions for trucks, busses, trailers, and motorhomes.

Granning Air Suspensions was founded in 1949 in Detroit, Michigan as a manufacturer of auxiliary life axle suspensions. Granning later became an innovator of independent front air suspensions for the motorhome industry.

Reyco Granning LLC was formed in early 2011 through a partnering of senior managers and MAT Capital, a private investment group headquartered in Long Grove, Illinois.

Reyco Granning manufacturing facilities are certified to the ISO9001:2015 standards, a globally recognized assurance that quality standards have been established and are maintained by regular rigorous audits.

correct service.


This service manual describes the correct installation procedures for the Reyco Granning ®

Passive Steer Tag suspension Model ASAPAT1000/1200/1400. Unit is also equipped with “Center on Reverse” technology. Overloading the suspension may result in adverse ride and handling characteristics and/or damage to the suspension.

You must read and understand all procedures and safety precautions presented in this manual before conducting any service work on the suspension.

It is important that the proper suspension be selected for the vehicle application. The required capacity, loaded frame to ground measurement, driveline clearance, axle travel, and axle spacing must all be taken into account.

Reyco Granning, LLC uses the following types of notices for potential safety problems and to give information that will prevent damage to equipment.

Proper tools must be used to perform the installation procedures in the manual. Some procedures require the use of special tools for safe and correct service. Failure to use the proper and/or special tools when required can cause personal injury and/or damage to suspension components.

CAUTION The ASAPAT1000/1200/1400 suspension, as with all suspension systems, must be installed at the proper Ride Height to insure trouble free operation. If the Ride Height is off, the suspension may not carry its share of the load under all conditions. Running at the incorrect Ride Height may damage the suspension or other vehicle components.

You must follow your company safety procedures and use proper safety equipment when you service or repair the suspension.

The information contained in this manual was current at the time of printing and is subject to change without notice or liability. Reyco Granning LLC reserves the right to modify the suspension and/or procedures and to change specification at any time without notice and without incurring obligation.

For additional information concerning suspension selection, contact the Reyco Granning, LLC Customer Service Department at 800.753.0050

Installer Responsibilities:

º To insure that the vehicle will function properly under the increased weight conditions and loading that will exist when an additional axle is installed.

loaded ride height of 8.5”

• To determine the correct location of thesuspension in order to provide the propervehicle load distribution.

• To insure that the load carried by each axleon the vehicle does not exceed the ratedcapacity of the components involved orexceed State and Federal laws where thetruck is operated.

• To insure that proper clearance existsbetween:

• The drive shaft and the tag axle onpusher units.

• Tires in the lateral, force, aft, and verticaldirections.

• Air springs when they are at theirmaximum diameter.

• Any other moving suspensioncomponents not listed.

Before beginning the installation:

1. Check that the suspension you received matches the specification provided to

you by your production or engineering department.

2. Check the drive shaft clearance for your suspension and verify that the vehiclesdrive shaft does not protrude past the frame lower than that dimension at thedesired installation location. This dimension is 10” for theASAPAT1000/1200/1400.

3. On any auxiliary axle application:

º Verify that axle spacing conforms to Federal and local bridge laws.º Verify that the auxiliary suspension location is based on front axle steering angle,

vehicle wheelbase and maximum recommended auxiliary axle spacing from center of tandem.

º Verify that the vehicle will have the proper load distribution after installation. º Verify that there is sufficient fore/aft frame rail clearance to mount the auxiliary suspension(s)

4. On Truck Frames:

º Verify that the frame width is within the allowable mounting range of thesuspension (See Table 1).

º Mark the location of the suspension side rails on the frame rails. (See Figure 6).Check for interferences with any existing brackets and bolts.

º Check for any interferences between the axle and the drive shaft, if applicable.

º Verify that the vehicle cross members and backing plates are correctly

positioned for proper support of suspension.

WARNING Adequate suspension support must be provided within the vehicle frame. See the suspension interface drawing for suggested frame crossmember

locations.

Installation Reyco Granning, LLC provides a

wide variety of suspensions to

accommodate most common

frame heights. The loaded frame to

ground dimension and the

intended tire size are used to find

the correct ride height of the

suspension.

The following formula may be

helpful in finding the correct

rideheight:

NOTE The loaded frame to ground

measurement should be acquired at the desired suspension location

on a LOADED vehicle.

CAUTION

The ASAPAT1400 suspension is custom fit for a specific frame height.

Using a spacer will result in component overload.

The suspension ride height is the distance between the center of the axle spindle and the bottom of the frame to which the suspension is attached. (See Figure 4).

Figure 4

The installed suspension ride height must be within the range specified on the

height table for the model being installed when it is in the LOADED condition.

CAUTION Installing a suspension with an out

of range ride height may result in insufficient axle lift, inadequate ground clearance, improper

loading at the axle, and suspension component overload.

Caster Angle

Caster is the fore aft angle of the axle king pin with respect to true vertical. (See Figure 5). Positive caster is when the top of the king pin is positioned rearward of the vertical position. Negative caster is defined as the top of the king pin being ahead of the vertical position. ASAPAT suspensions are built with preset positive caster (4°) from the factory. If your frame has more than 2° of rake, this can have an adverse effect

on steering. Please contact Reyco Granning, LLC Customer Service for further instructions if

this condition exist.

Camber Angle

A camber angle of 0.5° is preset at the factory.

Figure 5

Air Control System When installing your air kit (customer supplied) the following rules generally apply

1. Never add lubrication or anti-freeze to the air system.

2. Avoid drawing the air lines tight, kinking the air lines or passing themthrough areas that might cause damage.

3. Use only DOT approved air line fittings to plumb the system.

4. DOT type brake line should be used to plumb the system.



Axle Controls

When operating a truck in reverse, a steerable auxiliary axle must be raised or return to center. The ASAPAT1000/1200/1400 is of the return to center type. Only air control kits that allow this should be used.

Final Assembly

1. Install the air control kit and plumbing

2. Install wheels and torque lug nutsto wheel manufacturer’s.

3. Check that the steering axle

wheel bearings are filled with oil.

4. Install brake lines for steer brakes, per

the chassis manufacturer’s

specifications.

5. Make all ABS connections.

6. Inspect brakes and adjust if necessary.

7. On rounded snubber end, apply

thick bearing grease.

8. Adjust centering mechanism per OE

chassis direction in relation to drive

axle alignment.

Final Assembly Check

1. Check that all suspension boltsare tightened to therecommended torque values.(See Torque Tables).

2. Check air system for leaks andproper centering functionality.

3. Cycle the suspension through itsentire range with wheels and tiresinstalled, and check for interferencebetween the tires, wheel, axle, brakechambers etc. and the truck frame,body, or other components.

4. Inspect lug nuts for proper torque.

5. Make sure that wheels rotate freely.

6. Make sure that brakes areproperly adjusted.

7. Insure oil in the hubs is at theproper level.
