Fan Belt size

LW Hiway · Dec 17, 2009

I have a 51" SA w/123 gas engine and have over the last few years lost the correct sized belt for the fan to crank pulleys.

I know it was/should be at least 3/4" wide and have narrowed the length down to be between 31 and 34" long. As we are located somewhat in the sticks, running back and forth to find a belt is a pain.

Would anyone here have the correct belt sizes/dimensions?

Much appreciated

If you still are "as original" (no alternator conversion) why not just get one from a CaseIH dealer?

49291D BELT, generator, Serial # 250001 to 317191
52318DA BELT, generator, Serial # 317192 and up

(About $10 to $11 each.)

Or, a Gates or DAYCO dealer can PROBABLY cross the CaseIH number to their brand.
