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. * Use Tool (C) to turn the flywheel in the direction of normal engine rotation and install timing pins in the camshafts before the flywheel is removed. 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 engine oil pan into a suitable container for storage or disposal.4. Remove all of the bolts that hold the engine oil pan to the engine. Install two 3/8 in-16 NC guide bolts in each side of the engine oil pan. Fasten a hoist to the engine and lift the engine approximately 12 mm (0.5 in) off of the engine oil pan. Put two 50 mm wide × 100 mm long × 6 mm thick (2 in) wide × (4 in) long × (1/4 in thick) plates in position between the cylinder block and the engine oil pan on each side of the engine. Lower the engine on the plates and remove the hoist. The weight of the 3508 Engine is approximately 4445 kg (9800 lb). The weight of the 3512 Engine is approximately 5902 kg (13 000 lb). The weight of the 3516 Engine is approximately 7718 kg (17 000 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 approximately 245 kg (540 lb). 6. Remove O-ring seal (4) from the engine block.Install Flywheel Housing
1. Install O-ring seal (1) on the engine block and put clean engine oil on it.2. Put the flywheel housing gasket in position on the rear of the engine block. 3. Install two 5/8-11 NC guide bolts (2) in the engine block.4. Fasten a hoist to flywheel housing (3) with Tooling (A) and put the housing in position on the guide bolts. Install the bolts to hold the housing in position and tighten the bolts evenly. Remove the guide bolts and install the remainder of the bolts.5. Cut the flywheel housing gasket even with the bottom of the cylinder block.6. Fasten a hoist to the engine and lift the engine enough to remove the plates between the cylinder block and the engine oil pan. If the engine oil pan gasket is damaged, the engine will have to be removed from the engine oil pan to make a replacement of the gasket. Lower the engine on the engine oil pan and remove the guide bolts from the engine oil pan. Install all of the bolts that hold the engine oil pan to the engine. 7. Put camshaft gears (4) in position on the ends of the camshafts. For correct timing,
