Flywheel Housing Installation

INSPECTION

Inspect the flywheel housing machined surfaces, capscrews, holes and dowel locations for cracks or wear. Replace if cracks are evident.

Before installing the flywheel housing, examine the crankshaft flange for any cracks, surface damage or presence of foreign particles. This type of damage could ruin the sealing capabilities of the seal and lead to oil leakage.

DOWEL PINS

A combination of round- and blade-style locating dowel pins are used to install the front cover and flywheel housing. A blade-style pin is used for the flywheel. When installing the blade-style pins, make sure the blade is properly positioned: r Vertically (pointing up and down) for the front cover and flywheel housing r Parallel to crankshaft center line for the flywheel

CAPSCREWS (FLYWHEEL HOUSING)

The flywheel housing castings are manufactured to use standardized housing mounting hardware as follows: r Two upper external mounting location capscrews M3 (3 inches long) r Six internal mounting location capscrews M (2 inches long) r Eight washers used with aluminum housing part No. 35AX1489
