Spreader What belt is this ?

BertZegers · Oct 4, 2020

I have an International Harvester 103 manure spreader on which the belt is about to break.
I tried to find the part number, but no luck so far. Messicks has the IH 103 on file, but the belt is not listed.
I can measure the length of the old belt, but I think it has the wrong width and profile.
Does anyone have access to the Case database?

I checked Case/IH, and it shows the same thing as Messicks. I've also fired off the, I think 6th complaint letter, as to their revamping their parts site. Seems it would have been a lot simpler to put N/A after parts they don't handle anymore, then to go through and remove them. So a person could at least find and aftermarket alternative. I realize it's all about the buck, but doesn't say much for customer loyalty, that got them where they are.

Since they did this, I've started searching, and buying hard copy parts manuals, OEM if I can. Some reprints I've seen have poor photocopy issues.

A really long one..... Sorry could not help it.....

This chart may help determine belt type... Length should be easy after that.... Probably half dozen sources for belt once you know specifics...

I have tried the C, the width is right, but the angles are wrong. The sides don't touch, only on the top. The 5VX seem the right shape, but would run deep in the pulley. The 8VX is to wide.
The length is something like 270 inch and it drives everything. That's why I want to be sure I get the right belt.

Do Google IMAGES search for "V Belt Chart"......... More shapes than with just his one chart....

I've got a big book of belt specs and cross reference, there are a couple belts in the 272.2" OD and .875 TW range that might work. One has a cross section that resembles C above, and another that looks like the VX series. Look at a Dayco, Gates, Goodrich, Goodyear or Uniroyal C270 and see if it matches.

On something that old, you may be also dealing with worn pulleys. That might be why every belt profile you try does not match all profiles.
