International 500c crawler/Dozer

[my-handyman]

I'm hoping someone can Help me out!!!! I just bought this dozer and the left track will not pull or has intermittent power. We have changed the filters on the transmission, but it did not help.

When you want to go forward, you are suppose to be able to pull the lever forward to turn the dozer. However, when I pull the right-hand lever back the dozer will not turn. When I pull the left-hand hand lever back on the dozer the right-hand track turns.

Thanks for any and all help.

I have an old Cat, not an International... Is there a chance the steering clutch could be stuck or slipping?

I've seen it happen where one side will not disengage... often from lack of use over time.

Good Luck and maybe someone will post that knows Internationals.

ultrarunner; Thanks for the reply! The dozer did sit for about 5 years but the price was right. Went back out to ponder, it trys to engage and pulls about 1 foot but with the least amount of resistence it stops trying.

That might be why it has been sitting for five years! You might have an adjustment problem but it may be more serious from the way it sounds. You will probably have to have the drive flow tested to find out what might be wrong.

Old dozer = spending new money! (usually lots of it)

You may want to post your Q on the crawler forum at ytmag.com. Lots more old iron guys there.


Good luck!

When you pull back on the lever, you are applying the brake to stop the track and disconnecting the drive (clutch). First things first, get a service manual to get the adjustments correct. Someone along the way will have a "miracle cure" like soaking the clutch/brake in diesel fluid to loosen rust (anything oil based is a really bad plan). More than likely though, you will have to tear it down, clean, inspect, repair and replace to get the steering clutch(es) working right. It looks like a big deal, but you just need bigger wrenches and prybars to get it apart, back together and working right.

I got an old JD350B late last spring and spent $1100.00 to get new brakes, steering clutches, fluids and filter changes. Big money, maybe...but it works just right for I got it for, and it was entertainment for me to fix it.

crawlerheaven.com and heavyquip.com are decent parts sources
clutchandfriction.com is a good source for friction parts

My family has the same machine. If you pull the lever back part way the clutch on that side should disengage so the track no longer has power. You pull back further and you activate the brake band that locks the track. I in no way shape or form claim to be an expert but if it wants to go but is just not holding it sounds like a brake problem.

In general it's a decent machine but a little fragile. Not to scare you but from what I understand the clutches and final drives on the thing are a nightmare. Luckily we have not had to tear into ours . One thing to keep an eye on is water in the hydraulic reservior. Our shifter boot was shot and last time I change the transmission oil I drained 3 gallons of water out. I highly recommend heading over to Red Power Magazine (IH tractors and equipment) and checking out the construction equipment forum. I haven't been active for a while but there are a couple of guys that have 500c's and the folks on the board know IH machines inside and out.

Good Luck!

Check the transmission oil for water. Had the problem with the one I got and made a big differance
