Re: V8 pilot bearing

Ok, I broke down and dug my bearing books out of the basement when I use to do predictive bearing maintenance and bearing failure analysis.
Long story short, bearings are manufactured to metric specs, so it is easier to find when you break it down.

"The T85 snout measures .590 so the bearing ID would need a couple of thou clearance?
The bore in the back of the crank should be very close to 1.840 and is likely the same on all the V8 engines. The bearing definitely has an interference fit to the crank.
Gosh, this is fun. If I could have just retrieved the old (but mint) bearing, this would not have been a problem."
The MRC 204 is a 47mm OD bearing. 47mm = 1.85039
Here is a pic of what I came up with which is an offshore MRC 204S. $12.00
