D82U steering clutches stuck

Just what is a Jersey Box? Never heard of that term before. catskinner

Jersey box is a spreader, a light-duty vee blade with side-walls extending forward to a pair of 10.00-20 pneumatic casters, connected by a cross-bar with steel rollers on it which push the tires of a dumptruck as the dozer spreads the gravel and the truck dumps it into the box. Neater and more controllable, I suppose, than just tailgating the stone.

I'll get pictures next time I go down to work on it...It just came out of the thicket today, where it would have been hard to photograph.

Speaking of the box/blade, it went up but I can't get it to go back down....Is there an adjustment on the CCU for that? I do not think I have a CCU book

Thanks!

Any way you look at it, you are in for some work. The first thing needed is to get it to flat ground. Sometimes you can get lucky and fill the steering compartments part way with diesel and run it back and forth with the brakes held on hard and get the clutch discs warm enough to break free. Some folks have held the steering clutches back and push up against a tree or something really solid the break them free. If that doesn't work, the steering clutches will need to come out.

Here are some pics of the beast, stranded half in the driveway.[attachment=51056]D8 rear 14 10 18.jpg[/attachment][attachment=51057]D8 first move left side 14 10 18.jpg[/attachment][attachment=51058]D8 front 14 10 18.jpg[/attachment][attachment=51059]D8 CCU 14 10 18.jpg[/attachment]

We need more info on the steering clutches. On my old D8 the linkages were froze up. If you take the cover off and get in there with a bar you may have some success. You only need to get one to work to move it. I am impressed by your tracks. Maybe it was on Jersey box duty it's whole life.

Linkage only problem is a happy possibility....Is access through the oval sheet-metal covers under the seat, or do fuel tank and trans cover have to come off?

If I want to try the Diesel soak, do I our it in through those covers, or somewhere else? About haw many gal will be needed to half-submerge the clutches?

The tracks do look great. The heavy grousers were obviously welded on. The machine's supposed history includes building some miles of road in the area. I bought it from a limestone quarry.

Not sure on oval covers but wherever adjustments are made. My D8 is 1H, older. Liquid would go in there too. There should be drain holes underneath that would have to be plugged.

Sure you didn't have a brake locked? Usually it is a press the pedal and flip a latch to hold it type setup, but I haven't ever seen an old D8. Of course the brake linkage pins and pivots could be frozen up as well, keeping the brake band tight on the drum. Not having recent experience with the machine you probably wouldn't have noticed a "not quite locked" brake.

The method to remove the steering clutches described in the manual IS the easy way! The alternatives as designed into the D4 and D2 are much more labor intensive.

Most steering clutch compartment plugs I have run across are pipe thread. No idea what a D8 would use.
