In order to assemble the piston and the
connecting rod, proceed as follows:
- place the bushing

on the support
and attach the piston (with the arrow oriented
upwards) on the bushing;
Dismounting – Remounting
- lubricate the centering guide and the
piston bolt with engine oil;
- check the free gliding of the piston
bolt and the piston positioning.
