Stupid question:
 
I got a set of main bearings from "Hit n Miss"  for my FM "Z" 3hp and I
don't know which way to face the thrust bearing part. (Like I said up front
stupid question). It looks like it will work either way but with the crank
thrust spacer in place, the bearing thrust flange is a real tight fit on the
connecting rod side. It seems more logical to have the thrust bearing on the
inside of the main but the end play is only a few thousands and this seems
awfully tight for a engine with no pressure oiling.
 
I could chuck them up in the lathe and face them a little but it seems just
as illogical the they would machine them with the wrong dimensions.
 
Thanks and have a nice weekend,
Tom
