NOTE: New valves must be seated within the valve block to prevent leakage. To seat a valve, first install valve into the
valve block, then insert a brass rod (smaller than the spring) behind the valve. Give rod end a sharp tap with a
small hammer. This will seat the new valve within the valve block. Remove the brass rod and valve. You will
notice a circular pattern at the seat contact area of the valve. This pattern must not be broken or the valve will
leak when put into service. Repeat the seating operation if required.
2. Install supercharge relief spring (48) behind the valve.
3. Assemble a new o-ring (47) on plug (46), thread plug (46) into valve block (51) and torque to 128-148 lb. ft. (174-201
N.m).
4. Assemble each cross line check valve into it's appropriate valve block bore. Test cross line check valves (44) or (45)
for bind as noted in step G. 1.
5. Assemble two cross line check valve springs (43) into valve block (51), (color coded green).
6. Assemble a new o-ring (42) on each of the two hex plugs (41) then thread the plugs into valve block (51). Torque
plugs to 128-148 lb. ft. (174-201 N.m).

NOTE: If the bearing race was removed from valve block (51), install a new bearing race as shown in Figure 10. Use
tool shown in Figure 6. This completes the assembly of the relief and check valves into the valve block. The
gerotor parts will be assembled into the valve block during final assembly Section VI. Paragraph I.

NOTE: If new shaft bearings (19 or 38), shaft (24), valve block (51) or housing (8) are being replaced, a complete shaft
bearing preload adjustment must be performed. If the same parts are returned to service, the preload
adjustment can be omitted. The same procedure applies to yoke (37) and it's associated bearings.
1.
If the shaft bearing (38) requires replacement, install a new bearing race into housing (8). Use tool shown in
Figure 6 to press bearing race in place. Make sure the bearing race is oriented properly to accept the roller
bearing before pressing into the housing. The race must be bottomed against the shoulder of the housing at
completion of press.
2.
Place housing (8) on a flat surface with the shaft seal end down. Lay the front shaft bearing (38) into the race.
