8. Using a 1/4" hex wrench, remove the four socket screws
that secure the pump housing (9) to the gear housing (10).

9. Slide the pump housing (9) away from the gear housing
(10).
10. Remove and clean the housing gasket (11). Replace if
damaged.
11. Slide the crankshaft assembly (12), with the two thrust
washers (13) out from the gear housing side of the pump
housing.
12. Remove the output gear assembly (15) with the two thrust
washers (16, 17).
13. Thoroughly clean the crankshaft assembly, the output
gear assembly, and all the thrust washers.
14. Inspect all parts for excessive wear and replace if damaged
or worn. If the crankshaft or output gear assembly are
replaced, replace the corresponding thrust washers as
well.
15. Inspect the pinion gear on the end of the drive shaft for
wear. Replace if damaged or worn (refer to the "Servicing
the Clutch Assembly" procedure in this section).
If any of the gears are worn and require
i
replacement, check the grease in the gear
housing for metal particles or shavings. Remove
the contaminated grease. Replace the grease
that has been removed with fresh Lubriplate GR-
132 grease.

16. Slide the slider assembly (18) up and out of the slider
bushing (19) in the front of the pump housing (9).
17. Check the parts for wear.
a. If the slider bushing is scored or out of round the pump
housing should be replaced.
b. If the slider assembly is scored or the connection between
the connecting rod and slider assembly exhibits movement
other than pivoting movement, the slider assembly should
be replaced. The slider assembly also should be replaced if
the connecting rod bearing shows signs of wear.
c. Any parts that will be reused should be cleaned thoroughly,
including the connecting rod. Also, clean the crankshaft pin
that the connecting rod bearing rides on.
18. Coat the output gear assembly (15) and each side of
its thrust washers (16, 17) with fresh Lubriplate GR-132
grease. Place the thrust washers on their proper shaft of
the output gear assembly.
19. Lubricate the output gear assembly (15) with fresh
Lubriplate GR-132 grease. Insert the gear assembly into
its bore in the gear housing, gear end first. The teeth on
the gear will mate with the teeth on the drive shaft pinion.
20. Generously coat all surfaces of the cylindrical crankshaft
assembly thrust washer with fresh Lubriplate GR-132
grease.
21. Slip the flat end of the cylindrical thrust washer behind the
gear on the output gear assembly, lining its bore up with
the gear housing bearing bore for the crankshaft assembly.
22. Lubricate the crankshaft assembly gear with fresh
Lubriplate GR-132 grease. Slide the gear side shaft of the
crankshaft through the cylindrical thrust washer and into
its bore within the gear housing.
23. Position the pin on the end of the crankshaft (12) towards
the bottom of the gear housing (the bottom dead center
position).
24. Lubricate both faces of the large crankshaft assembly
thrust washer (13) with fresh Lubriplate GR-132 grease.
Place the thrust washer onto the crankshaft against the
gear.
25. Place the housing gasket (11) over the gear housing dowel
pins.
26. Lubricate the outside of the slider assembly (18) and the
inside of the slider bushing (19) with oil. Fill the slider cup
with Lubriplate 1242 grease (the slider cup is the area on
the slider assembly where the connecting rod and slider
join and pivot).
27. Insert the slider assembly (18) into the slider bushing (19).
28. Carefully place the pump housing assembly in front of the
gear housing assembly, lining up the gear housing dowel
pins with their corresponding holes in the pump housing.
Slide the pump housing onto the gear housing until there
is no gap between the housings and gasket.
