[SEL] Main bearings question

[Tom Smith]

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
