Timing gear

The timing gear can be easily pulled out thanks to the cylindrical type
of coupling.
However, if resistance is felt use a bearing puller.

Main bearing support, gear side

Remove crankshaft key and thrust bearing.
Loosen the three fixing bolts and remove the main bearing support on
gear side using two M 8x1,25 screws with fully threaded length of 60
mm.
Note: To avoid distortion it is not recommended to repiace the bea-
ring bushing.
Complete assemblies of bushing and support are available in
standard, 0,25 and 0,50 mm undersíze configurations as spare
parts.
When refitting tighten screws at 25 Nm.
