Re: TR6 Engine Overhaul

Hi gang;
   Just my $0.017634 worth. It seems to me that .003 is the high side 
of bearing clearances. The engine would be a little tighter with 
.0015-.002" clearance. Although .003 is within specs, it may cause a 
SMALL drop in oil pressure. I try to keep the tolerances a little 
closer when rebuilding engines. If only checking for owner's 
satisfaction, then .003 would be ok.
Here is a general rule of thumb. .001" clearance for every inch of 
journal diameter.
