Remove Flywheel Housing
Start By:a. remove electronic control module (ECM)b. remove flywheelc. remove crankshaft rear seal and wear sleeved. remove oil pan 1. Remove four bolts (1) and place bracket assembly (2) to the side of the engine. 2. Disconnect all electrical connectors (3) from the flywheel housing. 3. Remove two nuts and washers (5). 4. Remove two bolts (6) both sides and remove two oil drain tube assemblies (4). 5. Remove seven bolts (8) and two nuts (9).6. Remove lifting eye bracket (7). 7. Attach Tool (A) and a hoist to the flywheel housing.8. Remove all flywheel housing bolts (10). Remove the flywheel housing. The weight of the flywheel housing is 91 kg (200 lb).Install Flywheel Housing
Typical Example1. Install two 1/2 "-13 NC × 4" Long Guide Bolts in the cylinder block. Make sure gasket (12) is in position. The cylinder block, both sides of gasket (12) and the surface of the flywheel housing that makes contact with the gasket must not have any oil, fuel, water or gasket adhesive on them when the flywheel housing is installed on the engine.2. Install Tool (A) on the flywheel housing. Install flywheel housing (9) on the engine. The weight of the flywheel housing is approximately 91 kg (200 lb). Leave Tool (A) attached.
Torque Sequence Put 9S-3263 Thread Lock on bolts (17) through (20) before installation.3. Install the bolts that hold the flywheel housing in place.4. Use the following procedure to tighten the bolts: a. Tighten bolts 1 through 8 in number sequence to 136 14 N m (100 10 lb ft).b. Tighten bolts 9 through 20 in number sequence to 55 7 N m (41 5 lb ft).c. Again, tighten bolts 1 through 8 in number sequence to 136 14 N m (100 10 lb ft).d. Again, tighten bolts 9 through 20 in number sequence to 55 7 N m (41 5 lb ft). If a new gasket is installed, cut the ends of the gasket so it is even with the bottom of the cylinder block. 5. Install lifting eye bracket assembly (7). Install seven bolts (8) and two nuts (9). 6. Install two gaskets and two oil drain tube assemblies (4) both sides. Install two bolts (6) both sides. 7. Install tube assemblies (4) and inspect O-ring seals and replace if necessary. Install two nuts and washers (5). 8. Connect electrical connectors (3). 9. Install bracket assembly (2). Install four bolts (1).End By:a. install oil panb. install crankshaft rear seal and wear sleevec. install flywheeld. install electronic control module (ECM)
