➩ Insert the starter drive (Item 1) with thrust washer
(Item 2) into the housing (Item 3).
◆ Note:
Make sure that the correct sequence
is followed - it is no longer possible
to install the star ter drive after
inserting the clutch drum with the
drive gear.
➩ Position the balance drive gear wheel on the
crankshaft and locate the cutout in the gear
wheel on the Woodruff key, see Fig. 78.
◆ Note:
Make sure that the installation
position is correct - the balance gear
wheel and the balance drive gear
wheel are asymmetric. Incorrect
installation of a gear wheel therefore
leads to damage to the engine.
➩ Install the shaft circlip on the first groove in the
pinion shaft, using suitable pliers.
➩ Lubricate the inside of the needle sleeve with
lithium-base grease.
➩ place the needle sleeve on the pinion shaft and
coat the surface with Loctite 648.
➩ Fit the balance wheel on the needle sleeve,
making sure that the mark on the balance shaft
drive wheel lies between the marks on the
balance gear wheel.
➩ Fix the balance wheel with the second shaft circlip using pliers.
■ Attention: Check the installed position - the marks on the installed balance gear wheels must be as
shown in Fig. 79. Any other positioning of the gear wheels is not permissible, because this
would lead to damage to the engine due to vibration of the crankshaft.
