[SEL] Fairbanks Morse RR Motorcar Engine

Sat May 22 17:10:56 PDT 2010

Hi Richard, 

The problem is, these bearing shells are brass with what I presume to be a heavy overlay of babbitt on them. The babbitt is pretty much gone on one of the shells and the crank pin has been running on the brass. 

I am needing to get this babbitt put back on again.

You can see them in the pictures here:

If you scroll down a bit in the photos you will see the badly worn bearing shell that has most of the babbitt gone, I'm holding it in my hand. 

Ralph
