D2 3J Generator Belt

D2 3J Generator Belt was created by Lovey
Ive been fixing up my dads old Caterpillar D2 3J with him and we've gotten to the point of chaning all the fuilds and belts. Does anyone have an idea on what type of belt that would work? I've looked in many places for a belt that has the same size but I can't seem to find any.

If your Cat dealer doesn't have the right belt (you need a good parts guy....) I picked up some belts by size from vbeltsupply. All you need to do is measure the top width, bottom width (and figure the section) and then the outside diameter and match to their catalog

5B0243 is the correct belt for the D2 J series generator.
It is no longer available from Cat, measurement is 11/16' x 38.5", that is the measurement shown on the package, the actual outer width of the belt is 1-3/32''.
I have never found a direct replacement, but have a Dayco 28380 that is 38" and about 1/8" narrower than the Cat belt.
The belt can be properly tensioned by shimming the generator or the generator mount.
5B1925 is the pulley for that system.

My old Cat to Gates interchange lists it as a 174T Belt at 39-3/4" x 1-3/32"
Unfortunately Gates has changed their number system so many times I find it untraceable.
