I finally figured out how to attach photographs. Hopefully, a photograph is still worth a thousand words. As I mentioned in a prior post, I removed the outer support brackets on my HG42 and remachined each bracket and nut to eliminate excessive wear. This also eliminated the shims that had been installed over the years to compensate for wear. Everything fit perfectly and was reinstalled with no problems.

I next tackled the inner support brackets. First, the right bracket. Remachined everything with CNC equipment and reinstalled. The bracket holes are now approximately 1/8 to 3/16 of an inch below (or, out of alignment with) the tapped holes in the track frame. There was no problem removing the capscrews. The left inner support bracket has not been removed.

What is needed is to raise the support bracket and final drive relative to the track frame so that the capscrews align with the tapped holes.

Up to now, I have not loosened or removed the track to allow the final dive to be jacked/raised relative to the track frame... and thus allow the bracket capscrews to be installed in the track frame. Simply because that procedure was not required for reinstalling the outer support brackets.

My assumption is I will need to loosen or remove the track to allow the inner support bracket to align with the track frame. Is my thinking correct?

I called Landis and he suggested to loosen the outer support brackets. Really did not help. Thanks for your help and suggestions.
 

That will not work because the support bracket needs to be raised to allow the casting to fit tight against the track frame. My guess is I will need to loosen/remove the track over the rear sprocket and then jack the bracket to align the holes.

I'm not sure if I can attach a photo. Maybe a photo will give everyone a better understanding of the problem.

In the course of competing the restoration of my HG42, serial 57GA312, the rear support brackets required some attention. The outer brackets were removed along with the trunnion nuts. The casting bores were re-machined on CNC equipment along with machining new nuts. The outside brackets were reinstalled and assembled. Everything aligned perfect. Next, the right inside support bracket was removed from the track frame. All the usual wear shims were removed. It was apparent the shaft/bracket had not been lubricated for a long time. The inside support bracket was re-machined. As to be expected, the sleeve over the 116 951 Track Frame Shaft was worn. Measurements were taken and a new sleeve was machined to fit over the shaft. Everything fit and was reassembled to the frame.

I can not align the inner support bracket with the track frame to reinstall the capscrews. The bracket holes are about 1/8 inch too low.

I called Landis and he suggested I loosen the outside support brackets. I tried this and it still does not allow the inner bracket to properly align.

Jacking does not help the cause, as the outer support brackets are still attached. It just raises the frame.

I did take some track gauge measurements and there is approximately 3/4 inch difference between the top and the bottom.  In other words...it bows in/down 3/8 inch on each side.

Nothing in the service manual that I can find. Should I jack the inner support bracket from the slot cut into the track frame that is below it?

Any other suggestions? Thanks.

Might seem kinda trivial, but what is the correct paint color for the front and rear lights for the late HG Series crawler tractors? I have seen both green and black in color photographs and on crawlers displayed at shows.  I have a number of photos and books for reference, but everything is in black and white. It's dificult to determine exactly what is correct. My best guess is the correct color, from an authentic restoration perspective, is green.

Aslo, should the intake above the hood for the air cleaner be painted black? If so, my assumption is a gloss black.

Thanks for your help.

The problem is my terminology. I'm asking if there is a source for new trunnions and inner/outer support bracket castings. When I talked to Zimmerman's about it, their answer was that no such replacement parts existed. That's when I remachined my components. Machining new trunnions and pouring new support castings would not be difficult if the original drawings could be sourced for tolerancing purposes.

Does anyone supply reproduction trunion nuts and support castings for the HG Series crawlers? My were worn and I was able to remachine them to properly fit. Would need original drawings to determine machining tolerances.

I am searching for a replacement model/serial number plate to complete the restoration of my HG42. The original plate is badly worn. I realize many people would want to keep the original plate on the crawler. My view is somewhat different. Evrything looks new...why not the model/serial plate?
