Main/Rod bearing question
Main/Rod bearing question I picked up my block from the shop yesterday, and noticed they put different bearings in it. I looked at them this morning, and they seem to be Bi-metal bearings. The part number on the main bearings is 4115AU and the rod bearings are Speed Pro 8-2555A 10. I can't find any information on either one of these bearings, as to whether they are just OE replacements, or whether they will work with an aftermarket crank. Any ideas?
After putting the crankshaft in the block, and trying to get it to spin, it won't even do so regardless of the main caps being on it or not. I'm going to have to get my bearings back from them tomorrow.
I'm surprised then they didn't catch that. My shop is working my block right now and is checking for line hone, decking and everything else so I can just bolt it together. He showed me one build sheet where they even put in a different sized bearing for one journal to have the clearances all match
