REMOVE FLYWHEEL HOUSING
start by:a) remove exhaust elbowb) remove tachometer drivec) remove crankshaft rear seal and wear sleeve Make sure there is a new rear crankshaft seal and wear sleeve before the housing is removed. Anytime the seal is removed from the wear sleeve a new sleeve and seal must be installed.1. Remove brackets (1) and (2) from the engine.2. Use tooling (A) to remove the camshaft drive gears from the camshafts.3. Drain the oil from the oil pan.4. Remove all of the bolts that hold the oil pan to the engine. Install two 3/8" - 16 NC guide bolts in each side of the oil pan. Fasten a hoist to the engine and lift the engine approximately 12 mm (.5 in) off the oil pan. Put two 50 mm wide x 100 mm long x 6 mm thick (2 inch wide x 4 inch long x 1/4 inch thick) plates in position between the cylinder block and the oil pan on each side of the engine. Lower the engine on plates and remove the hoist. The weight of the 3512 Engine is approximately 5443 kg (12,000 lb). The weight of the 3508 Engine is approximately 4445 kg (9800 lb).5. Use tooling (B) to fasten a hoist to the flywheel housing. Remove the bolts and remove flywheel housing (3) from the engine. The weight of the housing is 245 kg (540 lb). After removing flywheel housing (3), clean the mating surface of the flywheel housing with tooling (C). If necessary, use a gasket scraper and a solvent to remove any residual gasket material. Both mating surfaces must be clean, dry, and free of any oil before installation.6. Remove O-ring seal (4) from the engine block. INSTALL FLYWHEEL HOUSING
(1) EAME1. Install O-ring seal (1) on the engine block and put clean engine oil on it. Refer to Engine News, 27 March 2006, "Sealing and Installing the Flywheel Housing" for more information. Ensure that the mating surface of the flywheel housing and the engine block are clean. Both mating surfaces must be clean, dry, and free of any oil before tooling (D) is applied.2. Apply a 6.0 mm (0.25 inch) bead of tooling (D) to the mating surface of the flywheel housing. 3. Install two 5/8" - 11 NC guide bolts (2) in the engine block. 4. Fasten a hoist to flywheel housing (3) with tooling (B) and put the housing in position on the guide bolts. Install the bolts and the hard washers to hold the housing in position and tighten the bolts evenly. Remove the guide bolts and install the remainder of the bolts.5. Tighten the 1/2 - NC bolts to a torque of 105 20 N m (77 15 lb ft).6. Fasten a hoist to the engine and lift the engine to remove the plates between the cylinder block and the oil pan. If the oil pan gasket is damaged, the engine will have to be removed from the oil pan to make a replacement
