6) Remove tension screw (36C) and take
seal sleeve (39) together with all mounted
parts out of the drive. Pull plunger pipe (36B)
out of the seal assembly and check for any
damage. Carefully, remove seal rings (40) and
sleeves (42) with a screwdriver.
seal sleeve (39) together with all mounted
parts out of the drive. Pull plunger pipe (36B)
out of the seal assembly and check for any
damage. Carefully, remove seal rings (40) and
sleeves (42) with a screwdriver.
4) Remove valve assembly (52) from discharge valve adapter (56) by gently twisting apart. The spring tension
cap (51A, 52A) is screwed together with the valve seat (51B or 52B). Screw off spring tension cap. Takeout
springs (51E, 52E) and valve plate (51C, 52C). Check sealing surfaces and O-rings (51D, 52D). Replace worn
parts. Coat threads of valve seat with silicon grease or molycote anti-seize Cu-7439 when reassembling.
Before refitting the valves, clean the sealing surfaces in the casing and check for any damage. Coat o-rings
(51D, 52D & 56A) with silicone grease to help with re-assembly. Replace valve assembly (51) and pressure
spring (57). Assemble valve assembly (52) to discharge valve adapter (56) by tapping together lightly with
rubber mallet. While replacing the valve assemblies use a rubber mallet to tap the top of the valve puller lightly.
This insures proper seating. Replace pressure spring (57A) and the discharge casing (50B). Tighten caps (58)
at 133 Ft-lbs; check torque tension after 8-10 operating hours.

5)
Remove hexagon nuts (49A) and valve
casing together with seal case (38) from
crankcase (1). If necessary, carefully tap the
valve casing (50) past the centering stud (50A)
using a rubber hammer.
IMPORTANT! If necessary, support the valve
casing by resting it on wooden blocks or by
using a pulley.
