REPLACING THE CON-ROD FOOT BUSH
During maintenance, if it becomes necessary to replace the con-rod foot bush, proceed as follows:
When removing the worn bushing, take great care not to damage or scratch the seat on the con- rod.
Perform cold press fitting of the new bush. During this operation, ensure that:
•
the lubrication hole coincides with the corresponding hole on the con-rod;
•
the cutting junction is directed as shown in (Fig. 32).
Then perform mechanical processing. The dimensions and tolerances shown in (Fig. 32) must be respected.
