Crankshaft Rear Seal and Wear Sleeve
HYDRAMECHANICAL SHUTOFF CONTROL
18. Put the washer in position and use tool (C) to install snap ring (39) on the carrier assembly shaft.
19. Install two bolts (40) to hold the gerotor pump group together as a unit.
20. Put gerotor pump group (41) in position on the housing assembly. Make sure the speed sensing valve is correctly engaged with the carrier assembly and install the eight bolts to hold the pump in position.
21. If necessary, make a replacement of dowels (45) and make sure they are 3.0 + 0.5 mm (.1 18 + .020 in.) above the surface of the valve body.
22. Put spring (44) and pilot valve (43) in position in the valve body. Put clean engine oil on the 0ring seal and install plug (42) to hold the spring and pilot valve in position.
23. Install three O-ring seals on air inlet shutoff valve (46) and put clean engine oil on the seals. Install valve (46) in the valve body and tighten it to a torque of 58 + 4 N•m (43 + 3 lb. ft.).
24. Install three O-ring seals on rack shutoff valve (47) and put clean engine oil on the seals. Install valve (47) in the valve body and tighten it to a torque of 58 + 4 N•m (43 ± 3 lb. ft.).
25. Install the seal in adapter (48) with tool group (A). Make sure the lip of the seal is toward the valve body as shown.

HYDRAMECHANICAL SHUTOFF CONTROL
26. Install O-ring seal (50) on adapter (48) and put clean engine oil on it. Install spring (53), adapter (48), nut (51) and knob (52) on manual shutoff valve (49). Tighten the nut to hold the knob on the valve.
27. Install manual shutoff valve (49) as a unit in the valve body.
28. Put pressure control valve (55) and the gasket in position on the shutoff control.
29. Install tube assembly (54) on the shutoff control.
30. Put four valve assemblies (56), three springs (57) and spacer (60) in position in the actuator valve body. Install gasket (58), cover (59) and the bolts to hold the valves, the springs and spacer in position.
31. Put the gasket, actuator valve (61) and the bolts in position on the pressure control valve. Tighten the bolts to hold the actuator valve and the pressure control to the shutoff control.
32. See CATERPILLAR FUEL INJECTION TEST BENCH, Form No. SEHS7465 Section IV, X for the correct procedure to adjust the hydramechanical shutoff control after assembly.
end by: a) install hydramechanical shutoff control.
