New here guys.
I have serial number HD11B-4597
Also have these numbers 11-4525 and engine HD-516.
I can't believe it started right up.
My first issue is the left steering clutch is stuck.
Any suggestions?
Is there anyone in southern Michigan that works on these?
Thanks

You can put the blade in the ground, pull the steering clutch and let it spin and see if lets go. I have never been that lucky. But many claim success that way.

If that doesn't work you take it apart and take the steering clutch plates apart. Brush all the rust off and put it back if the plates are in spec.

I tie that steering clutch back and work the dozer. Don't just spin a track. Work it back forth, do regular dozing so the clutches heat up and they're worked both directions generally works. Worked on my HD-7.

I have had some luck freeing stuck steering clutches, mostly bad. I think the worst thing a person can do is fill it with diesel or other petroleum products, it does not soften the rust or at least in my experience it does not help. I have used hot water with a bit of Muriatic Acid it seemed to help, may be phosphoric or citric acid would work better but the best thing I did was take an air chisel with rivet hammer in it and rattle the beegeebers out of the brake drum, there was a modicum of success.

Thanks for the reply Tad
I have not used any liquids at this time. I have tried working the dozer by ratchet strapping the steer clutch. So far no success.
Any chance I could get some photos of the brake drum rattling?
Again thank you

Sorry no pictures, that was years ago. A regular air chisel that most people have with a hammer point is what I used, adjust the steering clutch so when pulled back it is as open as far as it will go, tie the steering clutch back and let her have it. Try not to mar up the drum. On the 11 there is not a lot of room between the deck and fuel tank to get in to it but worth a try, I was working on D4 cats when I did it and the brake drum was visible from the back cover plate. I worked and worked on my 11 to free up one clutch with no success and when I took it apart all the clutch springs were broke in hundreds of pieces, they all looked like lock washers made from round stock. So if it wouldn't release without any spring pressure, it just wasn't going to happen. Like I said I have had some luck freeing them up, mostly bad, more often than not they have to come apart.
