Remove the two bolts (23) to remove cover assembly (31) from the plate. 17. Remove gasket (32) from the plate. 18. Remove plate (33) from the housing assembly. 19. Remove seal (34) from plate (33). Carefully remove driven gear (36) from sleeve (35) so brush (39) and spring (38) do not become lost.20. To remove the gerotor assembly, remove drive gear (37), driven gear (36) and sleeve (35) from the housing assembly. 21. Remove brush (39) and spring (38) from driven gear (36). 22. Use Tool (B) to remove snap ring (43) and remove seat (42), spring (41) and plunger assembly (40) from the housing assembly. 23. Remove O-ring seal (44) from the housing assembly. 24. Remove speed sensing valve (46), spring (45) and the seat from the housing assembly guide. 25. Remove ring (50) to remove race (49), bearing (51) and race (48) from seat (52). Loosen nut (47) to remove seat (52) and nut (47) from speed sensing valve (46). 26. Remove shaft (53) to remove lever (54) from the housing assembly. 27. Remove the wire seal and bolts (55) to remove cover (56), the two seats and the spring from the housing assembly. 28. Use Tooling (C) to remove the guide from the housing assembly. Assemble Hydra Mechanical Shutoff Control
1. If necessary, make a replacement of dowels (2) and make sure they are 3.0 0.5 mm (.118 .020 in) above the surface of the housing assembly. 2. Put guide (1) in position in the housing assembly and make sure the dash mark on the end of the guide is in alignment with hole (3). Use Tooling (A) to install guide (1) in the housing assembly. 3. Put lever (5) in position in the housing assembly as shown and install shaft (4) to hold lever (5) in position. Make sure the end of the shaft is even (flush) 0.25 (.010 in) with the housing assembly. 4. Put the seat, spring (7) and seat (6) in position in cover (8) and put cover (8) and the gasket in position on the housing assembly. Install the bolts to hold the cover in position. 5. Install nut (15) and seat (10) on speed sensing valve (9). Make sure the dimension between the end of the valve and the nut face of the seat is 117.21 0.25 mm (4.614 .010 in) and tighten the nut.
