3.0 Installation

Caution Follow safety guidelines utilizing lockout tag out

procedures before and during all installation and maintenance procedures.

Danger Ensure that proper rated lifting devices & procedures are followed when installing, working or maintaining unit. Failure to do so may result may result in equipment damage, personal injury and even death.

Caution Proper alignment is necessary to ensure that the friction discs track properly. Improper alignment will result in poor function and reduced service life.

Caution Even though the units are properly set before shipment from the factory, they should be checked for proper end play before being put into operation. See Section 3.3 for detailed instructions on checking the end play.

Danger Use only the proper quantity and grade of fasteners

shown in the drawings. Failure to do so may result in fastener failure and/or a reduction in unit torque.


3.1.0 REQUIREMENTS FOR PROPER OPERATION AND SERVICE LIFE

3.1.1 Preparation. Upon receipt of your WPT product, inspect for and report any evidence of damage. To avoid damage or personal injury, ensure that adequate lifting devices and hand tools are available. Compare the flywheel, flywheel housing, and pilot bearing bore to the bell housing, drive ring, and pilot bearing, respectively to ensure that you have the correct size unit.

3.1.2 Check flywheel and flywheel housing alignment. It is strongly recommended that dial indicator checks be made prior to installation of the PTO, especially on new engines or when a previous PTO failure might indicate an alignment problem.

3.1.3 Flywheel to housing face run out inspection.

Mount the indicator base on the face of the flywheel and position the dial indicator tip perpendicular to the flywheel housing mounting face. Rotate the flywheel 360 degrees while applying force to the crankshaft thrust bearing. The total indicator reading should not exceed the values listed in the table shown below in Section 3.1.4.

3.1.4 Check flywheel housing bore runout. Mount the indicator base on the face of the flywheel and

position the dial indicator tip so its movement is perpendicular to the pilot bore of the flywheel housing. Rotate the flywheel through 360 degrees.

The total indicator reading should not exceed:

SAE “00” Housing: 0.019 inches (0.483 mm)

SAE ”0” Housing: 0.016 inches (0.406 mm) SAE ”1” Housing: 0.012 inches (0.305 mm)

SAE ”2” Housing: 0.011 inches (0.279 mm) SAE ”3” Housing: 0.010 inches (0.254 mm) SAE ”4” Housing: 0.009 inches (0.229 mm)

SAE ”5” Housing: 0.008 inches (0.203 mm) SAE ”6” Housing: 0.007 inches (0.178 mm)

(Reference: SAE J617 table 1A)


3.1.5 Check flywheel face runout.

Mount the indicator base on the flywheel housing and position the dial indicator tip so that its movement is perpendicular to the face of the flywheel. Position the indicator tip near the drive ring mounting bolt circle diameter. Rotate the flywheel 360 degrees applying force to the crankshaft thrust bearing. The total indicator reading should not exceed 0.0005 inches (0.013 mm) per inch of measured diameter.

3.1.6 Check engine crankshaft endplay. Measure and document the engine’s crankshaft endplay before installing PTO. Using dial indicator as shown in 3.1.5 force the crankshaft back against the rear main bearing and then force the crankshaft to the front of the engine. Record the total movement as shown by the dial indicator.

3.1.7 Check engine radial play. Apply upward radial force by using a prybar to check the radial play in flywheel. Consult engine manufactures specifications to ensure correct tolerance.

3.1.8 Check flywheel pilot bore runout.

Mount the indicator base on the flywheel housing and position the dial indicator tip so its movement is perpendicular to the pilot bore diameter, to measure pilot bore runout. Rotate the flywheel through 360 degrees. The total indicator reading should not exceed 0.005 inches (0.127 mm).


3.2.0 OUTBOARD SUPPORT (if required) 3.2.1 Refer to Table 1 for the necessity of using an outboard support.

OUTBOARD SUPPORT REQUIREMENT

SIDELOAD APPLICATIONS IN-LINE

C106 Not Required Not Required




SP111 Not Required Not Required


SP311 Required Recommended




IBF314 Required Recommended

SP318 Required Required

Table 1 3.2.2 When installing a support bracket, ensure the PTO maintains proper alignment throughout the

flywheel, bellhousing & shaft. A dial indicator may be used to verify the PTO is not moving or deflecting during the installation process (see section 3.1). Shim and adjust the support as needed.

NOTE: the outboard support should complement the position of the PTO, not change it.

WARNING: Adhere to Table 1 regarding the necessity of an outboard support. The outboard support should not restrict flexure of the engine mounts. Failure to provide adequate support can result in personal injury and/or damage to the PTO.

3.2.3 See Figure 1 for Outboard support examples.

Figure 1

3.2.4 Models may vary, refer to assembly drawing for mounting requirements. Apply torque to outboard

support hardware in accordance with Table 9.

3.2.5 PTO deflection due to loads imposed by application should not exceed 0.010 in [0.254 mm]. deflection should be measured at the support plate pilot with dial indicator base mounted on a rigid part of the engine. (see section 3.1)


3.3.0 INSTALLATION OF DRIVING RING

3.3.1 Use the drive ring provided with the PTO or remove the drive ring from the engine flywheel to use

as an alignment gauge. Place the drive ring over the friction discs. Center the drive ring relative to the O.D. of the clutch body

3.3.2 Engage the clutch by operating the hand lever. Remove the drive ring. Do not disengage clutch until

installation is complete.

3.3.3 Mount driving ring (see sections 3.1 for proper alignment) on the engine flywheel, making sure it is seated properly.

3.3.4 Use SAE Grade 5 bolts (or equivalent) with lock washers and torque to the value in Table 9. Use the

engine manufacturer's torque recommendation if different from that in Table 9.

Use the engine manufacturer's torque recommendation if different from that in Table 9.

SEE Appendix B FOR PILOT BEARING INSTALLATION After completion of Appendix B, continue to next step.

3.4.0 INSTALLING THE UNIT

3.4.1 Prior to installation, grease the main shaft bearings, sliding sleeve assembly, and operating shaft. Apply grease to each fitting until grease just appears at the respective seal surfaces. Although the PTO is normally lubricated at the factory, this step will ensure that all moving parts are properly lubricated for initial use.

3.4.2 Remove inspection cover nameplate from the PTO bellhousing and slowly draw the PTO toward the

engine; this can be done by installing 3 or 4 equally spaced lengths of all-thread rod into the flywheel housing. Install nuts and tighten these while supporting the weight of the PTO with a hoist or cribbing.

3.4.3 As the PTO is drawn toward the engine, ensure that the pilot bearing engages the crankshaft, and the friction discs engage the teeth on the drive ring without binding or interference.

3.4.4 When the PTO is fully in place, remove the studs if used and replace with SAE Grade 5 bolts (or

equivalent) with lock washers and torque to the value in Table 9. Use the engine manufacturer's torque recommendation if different from that in Table 9.

3.4.5 Strike the output end of clutch shaft with a soft face hammer to relieve bearing preloading caused

by installation, see sketch below (appearance in some models vary).

Figure 2


3.4.6 The operating handle (hand lever) may be installed on either side of the PTO engagement shaft,

depending upon space requirements and convenience to the operator. Install lever with the cast hex facing away from the PTO. Engage clutch, remove handle and reinstall, align the splines so the handle positions is over center, while engaged. See illustrations below.

Figure 3

3.4.7 To check relief from bearing preloading, engage the clutch, then move the hand lever back and forth to feel the bearing endplay. Shaft and clutch should move .003” to .010” (.08mm to .25mm).

CAUTION: Operating handle must be mounted in the vertical position, just over center in engagement direction, to eliminate

excessive wear in the collar, See illustrations in Figure 3.

3.4.8 When installing PTO with operating shaft vertical, a stop collar should be added to the shaft on the topside for support. Failure to add stop collar will cause premature failure to the sliding sleeve collar assembly.

Figure 4

3.4.9 Re-check crankshaft endplay see section 3.4.5 If not the same as recorded in initial check, STOP and determine the cause. Crankshaft and clutch shaft must have the proper amount of endplay or bearings may fail.

3.4.10 Support plate is required for SP311/214/314 side load applications and recommended for in-line applications. Support plate is required for all 18” applications.

3.4.11 Automatic or Remote Engagement of the PTO.

NOTE: WPT recommends using only PTO’s with ball-bearing collars when using actuators.

3.4.11.1 This PTO design may be actuated by applying a force with a remote actuator to the handle of the PTO. There are many acceptable methods, such as; Hydraulic Cylinder, Pneumatic Cylinder, or Linear actuator. The principles of remote operation are simple, and all effort to identify problem areas, and best practices was applied to this section.

3.4.11.2 The actuator must be oriented such that the normal direction of its force remains tangent to the Arc of Engagement.


3.4.11.3 Size of actuator is critical. The actuator must be of sufficient size to apply the required amount of force on the handle. Too much force can cause permanent deformation of the Sliding Sleeve Assembly. Too little force will cause excess slippage, damage to the clutch and will eventually damage the Sliding Sleeve Assembly.

CAUTION:

Actuator force must be released once PTO is engaged or sliding sleeve failure will result.

3.4.11.4 The actuator’s end position must be adjustable to allow the connection with the PTO handle to be appropriately positioned. When adjustments are made to the Clutch, it is required to test, check, and correct actuators rod length to assure proper stroke length. The connection between the PTO Handle and Actuator must float freely after engagement, and after disengagement of the PTO. Short life of the Sliding Sleeve Assembly will result if slack between the handle and actuator is not maintained.

3.4.11.5 The actuators travel must be within appropriate limits to engage and disengage the PTO. Failure to adhere to this rule will cause failure and likely breakage of the PTO’s Clutch.

3.4.11.6 See Table 2 to determine appropriate force and stroke requirements.

WARNING: The WPT mechanical PTO is capable of side load and inline power transmission applications. Special care should be exercised when installing the PTO in an inline application. Due to engine movement and other factors that may cause misalignment, WPT recommends that a flexible coupling or drive shaft be used to join the PTO and driven shaft. If a coupling is used, ensure that it has sufficient horsepower capacity and that shafts are in line within the limits specified by the coupling manufacturer. If you are unsure about the procedure to align these shafts, consult the coupling manufacturer or WPT Power.

3.5.0 PTO ADJUSTMENT Clutch Adjustment The WPT mechanical PTO uses an adjusting collar to adjust for clutch wear. If the engagement force reaches 2/3 of maximum specified torque, clutch slips, heats excessively, or operating lever fails to stay engaged, clutch adjustment is required. 3.5.1 Remove inspection cover nameplate.

3.5.2 Disengage locking pin for “C” and “IBF” style clutches, pull locking pin out. For “SP” style

clutches, disengage locking pin by pushing pin in with a screwdriver.

“C” & “IBF” Figure 5 “SP”


3.5.3 Turn adjusting ring clockwise to increase clutch engagement force. For “C” & “IBF” style pull pin and rotate shaded assembly. For “SP” style push pin in and rotate ring.

“C” & “IBF” STYLE Figure 6 “SP” STYLE

3.5.4 Adjust clutch engagement force until the hand lever force required to engage the clutch is within the range specified on the inspection cover nameplate or Table 2 in this section.

3.5.5 Check engagement force with a torque wrench using the cast hex on the lever or check hand lever engagement force using spring scale at hand lever length “A” shown in of Figure 7 & Table 2

Table 2


3.5.6 Make sure lock pin is proper engaged after completing adjustment.

3.5.7 Replace inspection cover nameplate.

NOTE: New friction discs require frequent adjustments during an initial break-in period. Please recheck clutch adjustment after the first 10 hours of operation.

Clutch Adjustment Frequency

3.5.8 As clutch wears, the hand lever force required to engage clutch will decrease.

3.5.9 The need to readjust the clutch is indicated when the handle force has decreased to 2/3 of the

maximum force specified on the inspection cover plate OR anytime clutch slippage is

detected.

3.5.10 Do not adjust clutch so tight that hand lever force exceeds the maximum as indicated on the

inspection cover nameplate or Table 2.

CAUTION: Do not use any automated clutch engagement device which continues to apply pressure to the hand lever, after clutch is engaged. To prevent excessive wear to clutch sliding sleeve and other clutch parts, the hand lever should be allowed to rest in a vertical position with no external force applied to it once clutch is engaged.

4.0 OPERATION

4.1 Where high inertia loads must be started, engaging the clutch at idle speed may stall the engine. High inertia loads may be brought up to speed by engaging the clutch for short periods, (1 second) at intervals long enough to prevent excessive heat buildup in the friction discs. With extremely high loads, the engine may have to be operated at higher speeds while engaging the clutch. However, with a combination of clutch control and careful use of engine speed, a much smoother transition can be achieved by allowing the clutch to slip. Variations in engine revs are not immediately translated into changes in drive shaft rotation speed, but rather the friction on the clutch plate allows the drive shaft to gradually equalize with the speed of the engine.

4.2 Do not engage clutch above 1100 RPM. 4.3 Once the load is turning with the clutch fully engaged, the engine RPM may be

increased. 4.4 Do not run PTO disengaged for extended periods of time, doing so will cause premature

failure of the pilot bearing.

CAUTION: UNDER NO CIRCUMSTANCES should the clutch be slipped for more than four seconds maximum without either fully engaging the clutch or completely disengaging the clutch to allow it to cool. Any excessive vibration in the PTO should be cause for investigation. All rotating parts of the WPT PTO are balanced at the factory.

7.0 Maintenance

Warning Do not allow unqualified personnel to install, adjust and/or repair the unit. Faulty workmanship could result in faulty installation, dangerous operation of the Unit, repeated costly maintenance and greatly shorten the life of the Unit.

Warning Do not perform maintenance work on the unit, without making sure that the machinery will remain in a safe position. Failure to do so could result in serious injury or may cause death.

Warning Do not disassemble, install or perform maintenance work on the unit, without making sure that the entire manual is read and understood. Failure to do so could result in serious injury or may cause death.

Caution Examine the unit for wear of the friction material and the wear plates. Failure to perform this examination periodically may result in excessive wear to components, improper operation or a significant reduction in torque and may result in personal injury and/or damage to the machinery.


7.1 Maintenance schedule

7.1.1 WPT mechanical PTO requires lubrication, refer to Tables 7 & 8 at back of this manual for lubrication schedule.

7.1.2 Clean and repack & set main bearing every 2 years or 4000 hours of operation. Inspect sealed for life bearings every 2 years or 4000 hours of operation. Amount and frequency of lubrication are only a recommendation. Actual requirements will vary, due to load and operating conditions. New units should be monitored for heat and wear for a period of time, to determine actual needs.

7.1.3 Wipe off any excess grease from unit.

7.1.4 When washing the PTO be careful not to spray directly into where the solution will get inside the bellhousing and contaminate the clutch, grease fittings, bearings or shafts.

NOTE: Pilot bearing is “sealed for life” and does not require lubrication.

7.2 Adjusting main bearing

7.2.1 PTO main bearings should be adjusted to provide axial clearance in main shaft. Refer to Table 6 in back of this manual (18” PTO’s DO NOT have an adjustment)

CHECK AXIL CLEARANCE AS SHOWN

NOTE: All PTO’s are adjusted to side load end play tolerance at the factory.

7.2.2 Place PTO so the bellhousing flange supports its weight.

7.2.3 Mount dial indicator base on PTO housing.

7.2.4 Place dial indicator stem on end of shaft in a manner that will gauge shaft axial endplay.

7.2.5 Apply 200 lbs (90 kg) of “upward” force on shaft using a suitable hoist and lift device to fit the tapped hole in the end of the shaft.

7.2.6 Rotate shaft several revolutions.

7.2.7 Zero dial indicator reading.


7.2.8 Remove hoist from shaft and apply 200 lbs (90 kg) of “downward” force on shaft.

7.2.9 Rotate shaft several revolutions.

7.2.10 Read axial endplay from dial indicator.

7.2.11 Loosen bearing adjustment lock on inside of bell housing.

7.2.12 Rotate bearing locknut until proper shaft axial endplay is obtained.

NOTE: When loosening nut, strike output end of shaft with a soft face hammer to set bearing cup (outer race) against adjusting nut. See sketch in Section 3.4 Figure 2 for direction.

7.2.13 Adjust bearing locknut until nearest notch lines up with tab on bearing adjustment lock.

7.2.14 Install bolt through bearing adjustment lock and tighten.

7.3 Lubrication 7.3.1 Refer to Tables 7 & 8 in back of Manual for Lubrication schedule.

7.3.2 Use lubriplate 1200-2, lithium base grease with an ep (extreme pressure) additive on each of the following:

• Lubricate PTO bearings by applying grease until grease just begins to appear at the respective seal surfaces.

• Apply grease to sliding sleeve zerks until grease just begins to appear at the respective seal surfaces.

• Lubricate the engagement shaft by injecting 2 to 3 shots of grease in each zerk.

7.3.3 (Engage and disengage clutch 2 or 3 times to work grease in)

7.3.4 Repeat section as needed.

7.3.5 Wipe off any excess grease from unit.

7.3.6 Add caps to grease zerks only after all lubrication is complete, (installed caps signify lubrication has been completed).

Appendix B PILOT BEARING INSTALLATION Ball-Bearing (Non-Separable) Install pilot bearing onto clutch end of PTO shaft. Install the bearing so it is flush with end of shaft. Force should only be applied on the inner race of the bearing. Cylindrical Roller Bearing (Removable Inner Race) These bearings, have an installation that differs from the standard ball pilot bearings. If your PTO came with a split-type roller pilot bearing, please follow the steps, while referring to the Diagrams below.

1. Press the pilot bearing inner race on the end of the shaft, stopping when the bearing is flush with the shaft.

2. Measure the distance from the PTO bell housing face to the end of the bearing inner race.

Record this value, A: __________

3. Measure the width of the bearing outer race.

Record this value, B: __________

4. Subtract the value from step 3 from step 2 (A – B = C). This is the distance the outer race needs to be installed from

the engine bell housing face for proper alignment.

Record this value, C: __________

5. Install the outer pilot bearing race into the flywheel to the depth calculated in step 4. It is recommended to sign,

date, and retain a copy of this for your records.


Appendix C

Introduction to Sideload Sideload is defined by WPT as any application that imposes a radial force on the output shaft (example: belt or chain drives). WPT considers applications which are driveline driven to be Inline, not Sideload. The Sideload ratings for WPT Mechanical PTOs are shown in the following pages. These ratings are applicable when used in conjunction with WPT Power’s “Product Selection Calculations” located in the Power Drivetrain Product catalog (WLB-00-001). This catalog can be found by contacting WPT Power or by visiting www.WPTpower.com. For questions regarding Sideload, contact WPT Power Applications Engineering. Warranty will not apply to any application not approved by WPT Power. Selecting the Appropriate Sideload Chart Refer to the notes section of the assembly drawing for the appropriate Installation and Maintenance Manual and well as the unique Chart Number. The Chart Number corresponds to a sideload chart on the following pages. Use this Sideload Chart to determine the allowable sideload for the PTO. NOTE: Sideload chart on an assembly drawing supersedes this document.

Chart Number The chart number will follow the format: nnn-Yxxx, where:

nnn = PTO size: For example, 3-plate 11” PTO written as “311” Y = PTO Type: WPT “C”, “SP”, and “IBF” type PTOs will always be “1” xxx = Sequential number

This example produces a chart number: 311-1xxx Using the Sideload Chart A dimension notated as “X” will be located on a side view of the PTO assembly drawing. Use the appropriate Sideload Chart to find the PTO rating for the dimension “X” and associated speed. A typical PTO with dimension “X” is shown below. “X” is considered the centerline of your applied load to the PTO, otherwise called the “load center”. Operating with the load center, “X”, beyond the end of the shaft will lead to premature failure.

Appendix D OEM Clutch Pack Installation and Maintenance Instructions

Refer to the specific WPT clutch pack drawing as needed.

Installing the Clutch Pack on the Shaft:

1. See section 6.1.4 in this manual.

2. Torque specification for hub nut see Appendix A.

Aligning the Friction Discs and Assembling with the Engine:

1. Go to section 3.3 Installation in this manual.

2. Complete all the steps in this section. Disregard referral of Appendix B “Pilot bearing installation”.

NOTE: This unit is not equipped with a pilot bearing since the Clutch Shaft is supported with superior

methods.

3. Proceed to section 3.4 and complete 3.4.1 & 3.4.2

4. Skip step 3.4.3.

NOTE: As stated above, this unit does not require use of a pilot bearing.

5. Complete step 3.4.4.

6. Skip step 3.4.5.

NOTE: This step is normally done to relieve the Pilot Bearing and Main Bearings of axial preload caused by

slight interference of the Pilot Bearing and its bore in the Engine’s Flywheel. As stated above, this

unit does not require use of a pilot bearing.

7. Complete step 3.4.6.

8. Disengage the PTO after mounting to the Engine is complete.
