Sometimes you need a telescope to read those part numbers in those old books. lol

Many thanks! You are correct, it is 1039. I typed 1089 instead. I will see if NAPA can cross that number. If not I guess I will go CAT. NAPA is much closer to my house!
When I was looking at the mounting for the generator, I thought I was seeing some kind of stuff that looked like tin foil or some kind of thin metal still attatched to the machine. In the parts book, they list 3 shims. probably what I am seeing.
Since the fan belt was a good number, can I ASS U ME generator belt number good too? 5B 243.
As always, thank you for the help. Worth every penny of dues to belong to the club, to be able to access the vast quantity of knowledge just a click away!

5B243 is the correct number, the size is, 11/16" x 38.5" I don't think they are available from Cat, and finding an exact replacement may be tough, finding the same width and length may not be possible, as most of the replacement belts I see are a little narrower. That may not matter with applications like the fan belt where there is some adjustment available, but with the generator belt, you may have to use a slightly shorter belt if it's narrower, and there is usually some wear on the pulley.

You are correct, 5B243 is not available. Got the fan belt coming from Waco Tx It amazes me that they can have a 45 inch belt, but not continue to have a 38. Oh well. Thanks for the measurements. Fortunately, the parts store guy and I are neighbors. I am their favorite customer. Between Cushman and Caterpillar, Whenever I come in, all the counter people do a ;quick round of rock paper scissors to see who gets to help me this time!!

Thanks, I will give it a try.
