WARNING
INJECTION HAZARD
To reduce the risk of serious injury,
whenever you are instructed to relieve
pressure, follow the Pressure Relief
Procedure on page 9.
NOTE: Inspect parts as they are removed. Replace
parts that are worn or damaged.
1. Remove the displacement pump. See page 21.
2. Remove the pressure control (64). See page 26.
3. Turn the displacement pump rod (107) so the pin
hole aligns with the bottom drive housing screw
(5). See Fig. 23. Remove the three drive housing
screws (5). Also see Fig. 24 on page 25.

4. Remove the two motor screws (5). See Fig. 24 on
page 25.
5. Tap the lower rear of the drive housing (11) with a
plastic mallet to loosen the motor. Pull the drive
housing straight off the motor.
CAUTION
Do not allow the gear (16) to fall; it may stay at-
tached to the drive housing or to the motor.
Do not lose the thrust balls (11a or 4a) or let them fall
between the gears, which will damage the drive hous-
ing if not removed. The balls, which are heavily covered
with grease, usually stay in the gear recesses, but
could be dislodged. If the balls are not in place, the
bearings will wear prematurely.
6. Remove and inspect the crankshaft (12) and the
connecting rod (15).
7. Install the connecting rod.
8. Lubricate the inside of the drive housing bearing
with SAE non-detergent oil. Pack the roller bearing
and gears with the grease supplied.
NOTE: The gears and bearings between the drive
housing (11) and motor front end bell (C) should con-
tain a total of 3 fl. oz. (29 cc) of grease.
9. Route the wire harness (A) through the motor
passages to the junction box (59).
10. Place the large washer (12a) and then the small
washer (12b) on the crankshaft (12).
11. Lift the crank to the top of the stroke and insert
crankshaft (12). Align the gears and push the drive
housing (11) straight onto the motor and the locat-
ing pins. Install the screws (5). Torque to 80 in–lb
(9 N.m).
12. Install the displacement pump. See page 21.
13. Install the pressure control (64). See page 26.
Install the front cover (13).
