HD6G-Need Help-Clutches seized

After pulling your brake band pin/pins on the frozen side, tie the upper brake shoe back exposing the brake drum surface. Using strong bungee straps, tie your clutch release handles back in the normally released position and elevate the tracks clear of the ground/floor. Grab a torch with a small rosebud tip and while the frozen clutch assy. is spinning and driving the track, "play" the torch on the surface of the brake drum. Bring the temperature up but it doesn't need to be red in color. The purpose is to expand the internal diameter of the drum until clutch release pressure overcomes the bind and the clutch will release suddenly. You will see this with the release handles wanting to move from the tension of the bungee straps pulling. I've done exactly this on a couple tractors that have sat for years and elevating the temperature of the parts does work, but takes time. Just don't "dwell" in a single spot of the drum or mechanism for any length of time as no need to destroy parts unnecessarily. You can also do this to the clutch hub but the heat could be detrimental to the pressure plate springs. Really no need to get anything hot enough to cook seals, but heat will help break any bonds.

Have you tried a bar in the sprocket teeth between the track frame yet? While holding the stuck clutch handle back, ease the main clutch in as you don't want to break parts. This will load the steering clutch much harder than normal usage will. Before doing this ensure your track is tighter than normal:

   

Another thing you can do is remove the front brake band pin, (through the side of the case) unbolt the clutch assembly, then remove it from the tractor. Place the clutch assembly into a shop press and put about five tons of force on the pressure plate and soak the assembly with a penetrate. Let this dwell but keep it wet. Apply and release pressure repeatedly but don't deform parts. Once a minute amount of movement happens the assembly should break free. You will probably need to disassemble the clutch to further derust and clean things up. 

I think the heating of the drum and/or parts while they spin with the release handle tied back would be my first choice as hydraulic pressure against the parts that are frozen could damage the bearings or shaft that drives the final on that side. As Hector referred all the bolts did come out and none twisted off?

  tractor steering clutches. Unless the fibre clutches are removed and bi-metalic discs         installed, the fibre will attract moisture and rust. All drive teeth were coated with 

   anti seize  compound also.  You need to be able to steer it with the levers and not            oversteer with the brakes. The drums can be beat with a sledge hammer, an old fix, 

    but unless you rust proof it, it  will happen again. When we buy our next HD-6, it will      have wet clutches.
