Information:
Typical Example1. Remove bolts (1) and cover (2). Remove bolts (3) and cover (4).
Typical Example2. Remove bolts (5) and adapter (6). Be sure that gear stays in place. Remove bolts (7) and cover (8). Keep gear in place.
Typical Example3. Remove gears (9) and crankshaft gear (10). Remove bolts (11) and idler gear (12) with retainer. Remove bolts (13) and idler gear (14) with retainer.
Typical Example4. Secure strap and a hoist to housing (15). Remove hose assembly (16) and small bolts (17) and large bolts (18). 5. Remove bolts (19) that connect housing to oil pan (20). Remove housing from cylinder block. The weight of housing is approximately 105 kg (230 lb). 6. Check O-ring seal (21) and bearing (22) on adapter and replace if necessary. 7. Check bearing (23) and O-ring seal (24) on cover and replace if necessary. 8. Remove retainer (25) from gear (9) and check bearings (26) and replace if necessary. The following steps are for the installation of the flywheel housing.9. Thoroughly clean the contact surfaces of the cylinder block and flywheel housing. Install a new gasket between the flywheel housing and the cylinder clock.10. Secure strap and a hoist to the flywheel housing, put flywheel housing in position on the cylinder block. 11. Install the bolts that hold the flywheel housing to the cylinder block. Tighten bolts 1 thru 22 in number sequence to a torque of 40 10 N m (30 7 lb ft). Tighten bolts 1 thru 9 in number sequence again to a torque of 135 20 N m (100 15 lb ft). Tighten bolts 10 thru 22 in number sequence again to a torque of 55 10 N m (40 7 lb ft).12. Install bolts that connect housing to oil pan.13. Cut flywheel housing gasket off even with the cylinder block surface. Remove excess sealant.End By:a. install crankshaft rear seal and wear sleeveb. install starting motor
