1.0 Introduction
The WPT Power Pump Drive model WPD-05 is an innovative modular pump drive designed to be
mounted on industrial engines with SAE flywheels and housings. The input is a rugged Rubber Block
Drive flywheel coupling. This elastic coupling absorbs radial and angular misalignments as well as
dampens torsional vibrations. The model WPD-05 output is a dual pad pump drive as well as SAE
flywheel and flywheel housing. To allow for easy installation the pump tower can be mounted in 12
possible positions over 360 degrees. The output flywheel can accept transmissions, pumps,
compressors, and PTO’s.
Throughout the manual there are several HAZARD WARNINGS that must be read and followed to
prevent possible loss of equipment and/or personal injury and/or loss of life. The three warning words
are “DANGER”, “WARNING” and “CAUTION”. They are used to indicate the severity of the hazard and
are preceded by a safety alert symbol.
DANGER
Denotes the most serious injury hazard and is used when serious injury or death WILL result from
misuse or failure to follow the specific instructions sit forth in this manual.
WARNING
Denotes when serious injury or death MAY result from misuse or failure to follow the specific
instructions set forth in this manual.
CAUTION
Denotes when injury, product or equipment damage may result from the misuse or failure to follow
the specific instructions set forth in this manual.
2.0 General Warnings
Before assembling and operating the product, carefully read all the safety and operating instructions in
this manual.
Always follow all the instructions and make sure that all operators standing by the machinery are
wearing protective equipment necessary for the job type and application being performed.
WARNING
Do not use the machinery if you do not understand these instructions. Please refer to the
manufacturer or customer service for assistance.
WARNING
The product must be protected by a convenient cover guard to avoid personal injury or injury to
others.
Axial and radial ventilation openings should be incorporated in the guard for heat dissipation.

If the product is fitted with fusible plugs, the ventilation openings should not be directed towards
operators or any hot or electrical installation.
3.0 Installation
CAUTION
Before mounting the pump drive onto the engine, it is important to check that the flywheel is within
SAE tolerances.
3.1 Check that the flywheel is within SAE tolerances (see Figure 1).
3.2 Mount aluminum drive ring of the elastic coupling to the flywheel.
Figure 1: Checking that the flywheel runout is within SAE tolerances.
3.3 Mount the pump drive on the flywheel housing of the engine keeping in mind
to align the teeth of the elastic coupling in the respective teeth of the driving
ring. To align the pump drive housing and flywheel housing, use three threaded
rods with adequate lengths, mounted 120° apart on the flywheel housing. To
perform this operation, lift the assembly by using straps or other approved
means. In cases where the configuration includes a power take-off, support the
assembly adequately to ease alignment.
3.4 Mount the pump(s) on the head(s). Utilize pump manufacturers recommended
grease on both internal and external splines of the adapter.
3.5 Read pump(s) and other installed devices maintenance manual to assure
proper lubrication.

4.0 Maintenance
The WPD-05 is equipped with a toothed belt, which connects a pulley to the main shaft. The belt may
loosen over time while in use, so it may be necessary to check tension and adjust as needed. The belt
must measure 100Hz at ambient temperature. To adjust belt tension, tighten or loosen the 2 screws
(39). Once required tension is meet use nuts (40) to block/lock the tensioner. Re-check tension after all
adjustments have been made to confirm.
No lubrication is required for this unit. All bearings are sealed for life which require no maintenance.
5.0 Belt Replacement
To replace the belt, follow steps below. See exploded view in section 6.
5.1 Remove pump drive from engine.
5.2 Remove rubber block coupling assembly & key (8,9,12).
5.3 Remove flywheel from output side (33 &32).
5.4 Remove bolts to separate belt housing halves (20).
5.5 Separate housing.
5.6 Loosen tension on belt by adjusting (39).
5.7 Replace belt
5.8 Reassemble pump drive and install unit on engine. See Section 7 for bolt torque
specifications.
5.9 See section 4 for belt tensioning requirements.
