Marine Transmission Service Manual #1020667
Set the indicator gauge at zero (0). Lift the marine gear with a hoist, or other
suitable means, and place the unit in position against the engine flywheel
housing. Secure the flange of the marine gear main housing to the engine
flywheel housing. Use a feeler gauge between each mounting bracket and
engine bed rail. Add shims between the brackets and bed rails to equal the
feeler gauge readings. Carefully release the lifting force on the marine gear
while observing the indicator. The indicator gauge must remain steady at the
zero mark. Torque the bed bolts to the proper rating. If the reading moves
from zero, lift the marine gear and insert additional shims. Continue this
procedure until the marine gear is completely at rest on the bed rails and the
gauge maintains a steady zero reading. After obtaining the correct zero reading,
indicating no distortion of the engine flywheel housing, secure the mounting
brackets to the engine bed rails. Before securing the mounting brackets to
the engine bed rails, the propeller shaft should be checked for alignment.
Note: The transmission output flange and companion flange
bolts must be torqued to the proper value as identified in
Description and Specifications.
