Hello all. Several questions here. Decided to replace my rear main bearing seal ('76 302 out of a Mustang II). Luckily the engine is still on the engine stand and our new Tremec TKX is not yet attached. So, we rolled it over, pulled the oil pan, and removed the bearing cap. The seal came out relatively easily. Normally the rear bearing cap on these engines has a small pin that keeps the the seal from spinning. Ours is missing.
So missing pin questions - How important is that pin? Can I install a new seal without the pin? If not, is it possible to get a pin and reinstall it? See picture.
Then we noticed the dark coloring on the bearing and what looks like a chip in one corner.
So bearing condition questions - Should we be concerned with the dark coloration? and Is that chip by design to keep the bearing from spinning?
All thoughts, opinions, and suggestions greatly appreciated!
Thanks.
