Stepped Down Main Bearing Dowel Pin - All Aircooled Engines

This special dowel pin from JayCee is designed to replace the original dowel pins that hold the crankshaft main bearings into the crankcase journals.

Over time the holes in the crankcase which hold the bearings can wear and become elongated.

With this custom down pin you can drill out the hole in the crankcase to a larger size allowing the fitment of this stepped dowel pin.

Sold Separately.
