So I’m doing a rebuild on my engine and just put in stock sized main bearings torqued everything down and tried to turn the crank by hand and it wouldn’t budge but after I loosened the outer crank case bolts and the top inner bolt next to the timing sprocket it spun again(I did put assembly lube on both sides of the bearings but since then have wiped all of it off from both sides) can anyone help me out I’m stumped

 

Get yourself some plastigauge and use it to check your bearing clearances.

 

Second this, big time. Advance and some of the other parts houses carry it in stock.

 

I got it fixed guys thank you I just cleaned out the bore housings for the bearings and only put lube on the part that comes in contact with the crank and now it turns fine besides being tight from fresh pistons being in it lol
