thrust washer

I have a 1974 2002 and I am in the process of a rebuild....But! I ordered oversize bearings for the crankshaft and to my surprise the thrust washer is .25 over as well as the journal surfaces. What do you do in this case? I need a .25 over in the journal and need a standard size for the thrust washer. Any ideas?

There are only two ways to go about this...The "correct" way is to have your machinist remove the specified amount of material from the thrust surfaces of the crankshaft. The other way to resolve this is to use a belt sander with a fine grit paper and lightly hit each side of the bearing shell until you have adequate clearance. Folks may scoff at this maneuver but I've done it MANY times without any problems whatsoever.

say 400 mesh silicon carbide. This keeps the bearing thrust surface flat. Basically you just need to remove the babit from the surface and the bearing will fit with proper clearance. I have done this with no problems. I have heard from an experienced mechanic that there is not much thrust in these engines. The next time I had the thrust surface of the crank turned.
