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)
Page 22 of 58 WIM-TD-000_N
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).

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.

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
Page 25 of 58 WIM-TD-000_N
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.
Page 26 of 58 WIM-TD-000_N
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”
Page 27 of 58 WIM-TD-000_N
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

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.

7.1 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

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.

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.
