I just bought a 1979 international 175b track loader that needs a new track adjuster seal and sprocket from where the track has been slipping. All I have been able to find so far is sprockets for dresser 175c and td15. Will these fit or is the sprocket specific to a 175b?

Are you certain it is a 1979 175B?
I looked at machine 4291U001952 which is a C model, & it is as I understand a 1975 model.

What’s your serial number?

Not sure which number to go by. 9882 is 1965, 2615 is 1975. Some pics. of the whole machine may help determine how old it is.
I’ve noticed that the 175c has a u shaped shift pattern with the throttle beside the shifter and the b’s have a sideways E shaped shaped shift pattern with the throttle in the center of the dash. But my machine has the u shift pattern and the throttle in the dash so I’m not sure if it could be a early c and they just used whatever they had until they ran out or if someone has swapped parts around. But neither one seems like it would be an easy swap. So I’m not sure if this info helps any or not.

I think there were track gear upgrades between B&C series.
Not sure what they were....

I have friends have lost count how many 175 they own. They've sold several in the last few years, but more keep coming from the back corners of several pieces of property. I came close to buying one once, but chickened out with a broken crossmember I didn't have faith I could successfully weld.
Does anybody know where the full serial number is located and it may seem like a crazy question but where is the starter switch is located. The previous owner said he also couldn’t find it and has just been crossing out the starter

I think the tag in the pic. is the serial number. Just not positive how to read it. Maybe the gear shifter is different or maybe there are differences with the engine between B and C machines. If I had to guess I'd say the bottom 2615 is the serial number and the 9882 is like an arrangement number. Maybe someone on the Red Power forum could decipher it. The BP might mean B series powershift. An undercarriage shop likely will have a listing showing if the sprockets are the same. It looks like it might need a lot more than just sprockets.
This is what a C series tag looks like-
What he has is either a ROPS tag or a B series machine.
are the serial numbers stamped on the right rear finals on a 175 like they are on a 125?
*1974 model machine- my mistake.Are you certain it is a 1979 175B?

Going by that tag maybe I was correct that it's a B series with power shift. It has PS on the C tag too which I would think means power shift.
I’ll agree that for full time use it probably needs a lot more. But most of the slack you see is from the tensioner not holding pressure. As you pump grease in it comes out around the seal. But you can still just barely get it to the correct tension. And as soon as you go in reverse it pulls the idler all the way back. The right side wear matches all parts on the left besides the sprocket so I figured it was just wore from slipping on the track.

This may help some as it relates to IH undercarriage. It is a very good undercarriage guide. Scroll down to page 11. It lists the 175B/C having the same 7.00" pitch unless they have severe service track with 7.50" pitch. I'm not sure if the TD15B/C use the same sprockets, rollers or other components but it appears the rails may be the same. I would tend to think the sprockets may be the same but an undercarriage shop should be able to confirm if they are or not. It also uses a 175B as a sample for measuring wear. I think your serial number is the 9882. It might be the ROPS is serial 2615. The previous owner obviously told you the wrong year of your machine or was guessing.

While Caterpillar made a dedicated track loader, any parts shared were coincidental, IH converted a dozer chassis to serve as a track loader. I believe the TD 15 of the same vintage, whatever letter suffix would match except the shoes would be triple bar instead of tall single grouser.

Some Cat's were interchangeable like the D3 and 931. I think other track loaders share some undercarriage components with dozer models too.

Earlier C model machines had 5/8" bolts holding the sprockets on, not long into the run of C series they changed to 7/8" bolts holding the sprockets on. I believe all B series were held on with 5/8" bolts. 15/16" heads vs 1 5/16" heads.
