Use Tooling (B) to install bearing (3) in flywheel housing (4). The bearing joint is located at an Angle (XX) that is 15 3 degrees from the horizontal centerline. The oil hole in the bearing must align with the oil gallery in the flywheel housing. The bearing should extend beyond the surface of the flywheel housing by a Distance (YY) of 3.1 .5 mm (0.12 0.02 inch).
Install dowels (1) in flywheel housing (4). The dowels should extend beyond the surface of the flywheel housing by a Distance (ZZ) of 3.5 .2 mm (0.14 0.01 inch).
Install thrust washer (2) into flywheel housing (4).
Place adapter assembly (10) on the work surface. The outside face should be down. Install bearing (6) in adapter assembly (10) with Tooling (B). The split in the bearing should be located at Angle (X), which is 45 10 degrees from the centerline of adapter assembly (10). The bearing should extend beyond the surface of adapter assembly (10) by a Distance (Y) of 3.1 0.5 mm (0.12 0.02 inch).
Install dowels (8) and thrust washer (7) in adapter assembly (10). The dowels should extend beyond the surface of adapter assembly (10) by a Distance (Z) of 3.5 0.2 mm (0.14 0.01 inch).
Install O-ring seal (9) on adapter assembly (10).
Use Tooling (D) to install lip seal (12). Lubricate lip seal (12) lightly with the lubricant that is being sealed. Lip seal (12) should be installed to a depth of 2.5 0.5 mm (0.1 0.02 inch).
Install PTO shaft (5) and adapter assembly (10) into flywheel housing (4) and install bolts (11). Ensure that the flat side of adapter assembly (10) is against the flywheel housing. This will ensure that the oil passage is located toward the flywheel housing.
Install bearing (15) in idler gear (14) with Tooling (B). Bearing Relief Groove (V) must line up with Relief Groove (U) in idler gear (14) within two degrees. Bearing (15) must not extend beyond either face of gear.
Install idler gear (14) on idler shaft (18). Install the shaft and gear assembly in the flywheel housing. Tighten bolts (19) and (20) in a clockwise pattern to a torque of 100 20 N m (74 15 lb ft).
Install Tooling (A) in the crankshaft. Install seal (16) and crankshaft gear (17).
Install gasket (21), cover (22), and bolts (23).End By:
Install the crankshaft rear seal.
