replacement of steering clutchs in D-4

hey 6600
A while back,10yrs ago I had the same problem.Due to lack of funds"Money"😠 I just sand blasted the steel & fiber disks they cleaned up good.I then reinstalled them and I never had a problem since.😊 If you can afford the new plates go for it.If not try the cleanup route.I am working on a D4 I have the same problem with this machine,I was told by a old time "Cat Operator" they just cleaned the plates replaced any broke disks and keep on working.Good luck Steamroller😎

Sidehill;
I just used fine sandpaper and an orbital sander to clean up the fiber and steel disks on the left side of of my JD40c. Now it works like new

sidehill,
After you get 'em cleaned up, restack 'em and measure. Unless you're close to the lower tolerance I'd say reuse 'em. Even in heavy use, those clutches don't wear very fast. I "overhauled" one side on my D4 as it was frozen and after it cleaned up it measured well within tolerance so it went back in. In the year plus I've been using the critter plowing deep snow, shoving fill back in around foundations as well as a bunch of skidding logs I've only had to readjust the steering clutches once and that was within an hour of putting everything back together again.

hey..thanks for all the help...I will clean them up and put them back to work...as I was cleaning up the tapered roller bearings on the bevel gear shaft..the same shaft the clutches are on and I noticed some pitting on the rollers(cause by rust I think) and also some on tapered face the rollers ride on..I would says 5% or less...no metal coming off..just the pitting..safe to go back together..??? 😞

I replaced the tapered roller bearings and the throw out bearings on both sides. I did not do anything with my clutch discs or spacers other than insure they were not stuck together. I was within tolerances and did not want to spend the money. I figured the bearings were a better place to spend and the right side throwout was a crumbled mess...brake linings were totally gone from the bands. Worn to the steel.

The discs and spacers I priced shipped were approaching $800 for the full set.

As for adjustments, I need to back my adjustments off a bit. Mine actually tightened a little. I started with the three inches and may have an inch now after bout six hours of running over several instances.

Post some pics.
