Typical Example24. Disconnect oil line (35) and leave the line with the engine.25. Disconnect oil line (34) from the steering cylinder for clearance purposes.26. Disconnect two wires (37) from manifold (36). Remove manifold (36).
Typical Example27. Disconnect wires (38).28. Remove bolts (39) and (40) that hold bracket (41) in place. Pull bracket (41) off to one side and away from the transfer housing. 29. Disconnect universal shaft (42). 30. Remove universal shaft (43) and dipstick fitting (44). 31. Fasten tool (A) and a hoist to the engine, transmission and transfer gears as shown.32. Remove bolts (45) from the front mounting support. 33. Loosen bolt (46) on rear mounting support bracket enough so that the engine can be lifted slightly to properly adjust tooling (A).34. After proper balance has been achieved with tooling (A), remove four bolts (47) that hold mounting brackets (48) to the transfer case.35. After removing four bolts (47) from both mounting brackets (48), remove the one (46) that holds the mounting bracket directly above the transfer case drain plug and remove bracket (48).
Inspect the areas in and around the engine and power train unit to make sure all disconnections and removals have been made before the engine and power train unit are to be lifted from the mounting frame.
36. Slowly lift engine, transmission and transfer gears out of the machine. The weight of engine and power train unit (49) is 1558 kg (2125 lb). Once the engine and power train unit has cleared hoses, wiring and machine frames, move the unit away and support it in a proper, safe and suitable manner.Install Engine, Transmission & Transfer Gears
1. Fasten tool (A) and a hoist to engine and power train unit (49) and put it in position in the machine frame. 2. Install mounting brackets (48) with bolts (46) and (47) that hold them. Leave the bolts loose at this time. 3. Install bolts (45) on the front mounting supports. Remove tool (A) from the power train unit. Tighten all mounting support bolts. 4. Install dipstick fitting (44) and universal shaft (43). Torque bolts to a torque of 70 15 N m (50 11 lb ft). 5. Connect universal shaft (42). Torque bolts to a torque of 70 15 N m (50 11 lb ft).
