Flywheel, flywheel cover

General

The motor may be equipped with a back plate of

aluminum or soft carbon steel or a flywheel cover of

cast iron. Marine engines have an aluminum adapt-

er housing between the back plate and the reverse

gear.

The steel flywheel has a hardened ring gear which

is installed by the process of shrinking-on. The ring

gear has 104 teeth.

Repair Instructions

(21A-01)

Remove the drive components from the rear end of

the engine.

Remove the adapter housing for the reverse gear.

Remove the elastic drive disc from the flywheel.

Remove the two counter-positioned mounting

screws from the flywheel. Temporarily install two

guide pins to ensure the safe removal and installa-

tion of the flywheel.

Remove the remaining mounting screws and re-

move the flywheel.

Check the flywheel and ring gear for signs of dam-

age and replace if necessary.

Check that the mating surfaces of the crankshaft

and the flywheel are clean and undamaged.

Check that the guide pin is installed in the crank-

shaft flange. Install the flywheel over the guide pins.

Install the four mounting screws. Remove the guide

pins and install the two remaining mounting screws.

Tighten the screws in stages and evenly to 65 Nm.

Check the radial run-out of the flywheel using a dial

indicator (A). The run-out must be less than 0.30

mm as a total reading on the indicator.
