ASSEMBLY
OIL PUMP BUSHING





1. Assemble Tool Handle C-4171 and Bushing Installer SP-5118 (Fig. 112).
2. Place bushing on installer tool and start bushing into shaft.
3. Tap bushing into place until Installer Tool SP-5118 bottoms in pump cavity. Keep tool and bushing square with bore. Do not allow bushing to become cocked during installation.





4. Stake pump bushing in two places with blunt punch. Remove burrs from stake points with knife blade (Fig. 113).

REACTION SHAFT SUPPORT BUSHING
1. Place reaction shaft support upright on a clean, smooth surface.





2. Assemble Bushing Installer Tools C-4171 and SP-5302. Then slide new bushing onto installer tool (Fig. 114).
3. Start bushing in shaft. Tap bushing into shaft until installer tool bottoms against support flange.
4. Clean reaction shaft support thoroughly after bushing replacement (to remove any chips).

OIL PUMP BODY
1. Lubricate pump gears with transmission fluid and install them in pump body.
2. Install thrust washer on reaction shaft support hub. Lubricate washer with petroleum jelly or transmission fluid before installation.
3. If reaction shaft seal rings are being replaced, install new seal rings on support hub. Lubricate seal rings with transmission fluid or petroleum jelly after installation. Squeeze each ring until ring ends are securely hooked together.

CAUTION: The reaction shaft support seal rings will break if overspread, or twisted. If new rings are being installed, spread them only enough for installation. Also be very sure the ring ends are securely hooked together after installation. Otherwise, the rings will either prevent pump installation, or break during installation.

4. Align and install reaction shaft support on pump body.
5. Install bolts attaching reaction shaft support to pump. Tighten bolts to 20 Nm (175 inch lbs.) torque.





6. Install new pump seal with Installer Tool C-3860-A (Fig. 115). Use hammer or mallet to tap seal into place.
7. Install new O-ring on pump body. Lubricate oil seal and O-ring with petroleum jelly.
