FLYWHEEL HOUSING
The flywheel housing is a one-piece casting, mounted against the rear cylinder block end plate, which provides
a cover for the gear train and the flywheel. It also serves as a support for the starting motor and the
transmission.
The crankshaft rear oil seal, which is pressed into the housing, may be removed or installed without removing
the housing (Crankshaft Oil Seals).
