STEERING CONTROL RRASSEMBLY
Position the cap locator bushing with large O.D. chamfer UP partly into end of housing (refer to Fig. 40).
Insure that it seats against spool assembly flat and smooth by rotating with fingertips.
Check the mounting plate and shaft seal carefully to insure that they are clean and in good condition. Insure
that the mounting plate seal grooves are clean and smooth. Each of these seals is slightly larger than its seal
groove so that they will be adequately retained in service. Push each gently into place and smooth down into
seal groove with fingertip (refer to Fig. 41).
Quad ring shaft seal may be used to replace O-ring shaft seal in early units and will
function properly in original seal groove.
Thin oil seal at exterior of mounting plate is a dirt-exclusion seal and does not generally need replacement. If
this is replaced it should be pressed into counterbore so that the lip is directed away from the unit.
Place the mounting plate subassembly over spool shaft and slide down into place over cap locator bushing
smoothly so that seals will not be disrupted in assembly (refer to Fig. 42). Align boltholes with tapped holes.
Be certain that the mounting plate rests fairly flush against end of housing assembly so that the cap locator
bush- ing is not cocked and install four mounting plate capscrews. Tighten these evenly and gradually to 21 lb
ft (28.5 Nm) torque. (Refer to Fig. 43.)
