About to order kit for main bearings and was wondering about the #'s on the main bearing itself.on one end it has a 10A and below it 181201501 and on the other end it has A-07.Was thinking there might be some info that is unique like .10 over (10A) and p/n 181201501 and the A-07 would be cylinder #7.just curious.Thankx

 

Good deductive reasoning to me! I havent messed around deep enough yet with these motors specifically, but I think you are on the right track!
