Fasten a hoist to the engine and lift the engine approximately 12 mm (0.5 in) off of the oil pan. Put two 50 mm wide x 100 m long x 6 mm thick (2 in wide x 4 in long x 1/4 in thick) plates in position between the cylinder block and the 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).

NOTE: The following steps are for installation of the front drive housing.
10. Put the housing gasket in position on the front of the cylinder block. Install two 5/8" -11 NC guide bolts (14) in the cylinder block.
11. Fasten a hoist and tooling (A) to front drive housing (12). Put housing (12) in position on the guide bolts to hold it in position. Remove guide bolts (14) and install the remainder of the bolts. Tighten all of the bolts evenly and cut the housing gasket even with the bottom of the cylinder block.
12. Fasten a hoist to the engine and lift the engine enough 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 of the gasket. Lower the engine on the oil pan and remove the guide bolts from the oil pan. Install all of the bolts that hold the oil pan to the engine.
13. Put clean engine oil on the O-ring seal and install cover (11) on the drive housing.
14. Install clip (8), the washer, and bolt (9).
15. Put washer (7) in position inside the drive housing.
