Locating plate

A locating plate for the crankcase, used to hold the main bearing bushing in place.

PN · 70-4139

70-4139 is a locating plate that shows up in the crankcase section of the parts books, where it works with the main bearing bushing to hold it in position in the case. It's a small piece but it does a specific job — keeping that bushing from rotating or walking out of its bore once the cases are together.
