Removal and assembly of the drive shaft gear

The gear on the timing system side can only be replaced.

To demount it, use puller code 00365R0100 (fig. 56) or a puller

available on the market.

To assemble, preheat the gear to a temperature of about 180 to

200 °C, fit it on the shaft, taking care to ensure that the chamfer

points towards the internal part, and use the tang as a reference.

Drive shaft assembly (fig. 57)

Mount the drive shaft after having fixed the first shimming

washer to the casing with Loctite 648 and after having inserted

the needle bearing and the second shimming washer.

After having fitted the bearings into the small end, connect the

connecting rod to the crank pin as shown in fig. 58.

Mount the connecting rod cap with the reference numbers

matching those on the rod.

WARNING: mount the connecting rod half bearing

with the positioning mark on the cap and that without

positioning mark in the center of the rod, in compliance

with the dimensions indicated in fig. 58.

Evenly tighten the connecting rod bolts to the following value:

3,8 ÷ 3,9 kgm (37,3 ÷ 38,2 Nm)
