Note: Inspection or replacement of the main bearing can be done with the crankshaft in place. The stud tensioner tool group is used with the handling tool group. The stud tensioner tool group and the main bearing cap can be raised and lowered by using the handling tool group.The handling tool group includes supports (1), movable tray (3), and pins (2). Pins (2) are installed in the main bearing cap during removal.Brackets (4) of the handling tool group are bolted to the openings of the crankcase access covers. Adjustment screws are used in order to level the tensioner or the main bearing caps.Note: When you assemble the handling tool group, always use the spring clips. The clips will prevent components from dropping into the oil pan. Link (5) connects to either the tensioner or pin (2) .
Remove the remaining crankcase access covers.
