Driv-Lok Pin
Seal the Driv-Lok pin (73) to the pump block (84) with
a 1.5 mm (1/16") bead of an RTV-type silicone-based
sealant, such as Dow Corning 732™ Multipurpose
Sealant or equivalent.
Sealing Instructions for Assembly
Motor
If the motor has been disassembled, seal with a 3 mm
(1/8") bead of a silicone-based gasket/flange sealant,
such as Loctite®587 Ultra Blue®, as follows:
(A) To the mounting surface around the threads
(four locations)
(B) To the chamfer (four locations)
(C) Around the innermost machined circumference
of the mounting surface
Apply a 1.5 mm (1/16") bead of an RTV-type silicone-
based sealant, such as Dow Corning 732™ Multipurpose
Sealant, as follows:
(D) Around the motor bearing screws (two locations)
Assemble immediately.

Repairs
The following section and figures describe pertinent
details for refinishing ball seats and component
re-assembly and adjustments.
Motor Face Seal
When reassembling the motor, refer to Figure A1 for the
face seal seating dimension. Also, refer to this figure for
setting the vertical position of counterweight (32).
Manual Release/Automatic Release Valve
Handle Setting
Refer to Figures A2 and A3. Thread in the shaft (62) until
it just touches the check ball (55) (in its spring-loaded
closed position). Slide collar (104) on the shaft. Position
the handle (61) at the location “Position 1” (Figure A3),
with the other surface of the handle flush with the end of
the shaft. Lock in place. Rotate the handle to “Position 2”
(Figure A3). Slide the collar toward the valve body until
it contacts the 15.9 mm (5/8") diameter portion of the
control shaft. Rotate the lock collar clockwise until it
touches the stop pin, and lock in place.
When locking control handle and lock collar in place,
torque set screws tight to 2.8–3.4 N·m (25–30 inch-pounds).

Low-Pressure Bypass Check Pressure Adjustment
When properly set to the dimension shown in Figure A5,
the high pressure stage operation of the pump will be
delayed approximately one (1) second after the motor
starts. This delay is created by the closing time of the
pilot-operated valve.
Note: This dimension must be increased if ball
seat depth is increased by more than
.4 mm (1/64 inch).
Increasing the bypass pressure (CW rotation of adjusting
screw—increase of set dimension) will shorten delay. If
delay becomes too short, the motor will not restart when
high pressure is held in the line. The motor should restart
with a maximum required off time of 1/2 to 1 second.
Decreasing the bypass pressure (CCW rotation of
adjusting screw) will increase delay. The pilot-operated
valve will not close if pressure is set too low.
Changes in oil temperature (viscosity) will affect the
amount of delay. The pumping delay will increase with
rising oil temperature (thinner oil).
Low Pressure Relief Setting
Refer to Figure A4. Lightly bottom the stem (44) on the
ball (46). Then, back out the stem 3-1/2 turns. Tighten
nut (43). The resulting pressure setting should be
approximately 19 Bar (280 psi).

High-Pressure Inlet Check Ball Travel
The amount of allowable ball travel is critical to the
optimum high pressure output (flow rate). Refer to Figure
A5-1. Carefully and accurately measure (depth “mike”)
the “A” dimension (top of pump block to seated ball)
and “B” dimension (top of pump block to head of plug—
at center). Carefully and accurately set the “C” dimension
(overall length of assembled plug and pin) of a
new plug and pin equal to “A” minus “B” minus
.305 ±.050 mm (.012 ±.002 inches).
Ball Seat Refinishing
Refer to Figures B2, B3, and B4 for the proper drill size
to refinish the conical seat and finish ream size. These
operations must be performed with the pump or valve
block properly held and using a drill press. Only a very
small amount of material should be removed.
