Kolbenbolzen 18MM

The piston should be renewed along with the other components that make up this assembly including piston rings, this PISTON PIN and the piston pin retention circlips - all pretty much essential when rebuilding the engine.

Interfacing new parts with old will cause the new parts to wear prematurely and lead to a less than satisfactory outcome - this superb engine deserves only the very best!

• Where possible always try and renew the complete assembly.
• Interfacing old parts with new rarely has a happy outcome!
