R975 rear main bearings
I think you make a good point Peter, clearly the large channel around the bearing exterior is an oil channel ( you can see the small holes leading to the interior) so sticking a notch which presumably holds something must restrict or enhance oil flow?? don;t know but at some point will pull a bearing out of a battered crankcase to see.
Hanno, in my book a HUP is a HUP and more importantly in this day and age they have both survived the scrap man! Thanks for the post!
