1.0 Introduction
The WPT Power Pump Drive model WPD-03 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-03 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

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

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.
Maximum ambient temperature 122 F° [50 C°].
Ambient reading should be taken from 8-12 inches [20-30cm] away from unit and at 2 to 3 locations to
get an average.
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.

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 by removing bolts (32) and install into (31), use
them as jack bolts to separate from (25).
5.3 Remove flywheel (3) from output side.
5.4 Remove nuts (34) from output side to remove output flange and spacer (36) & (37).
5.5 Remove nuts (34) from engine input side to remove input flange (14).
5.6 Remove bolts (12) to separate belt housing halves (8).
5.7 Replace belt
5.8 Reassemble pump drive and install unit on engine. See Section 7 for bolt torque
specifications.
