Fitting tips

1. Check that the pin diameter and length match your piston (see specifications).
2. Oil the pin, the small end and the piston bosses, then push the pin in by hand, without forcing it.
3. Fit new piston pin circlips, gap opposite the notch, and check they sit properly in their groove.
