The outside part of the stub shaft is cast iron. That does not take weld very well.  I would clean the stub shaft well with a wire brush. Then get some JB weld or similar epoxy and use that to glue the bushing to the shaft.

It makes sense to me that the bushings would be a press fit on the stub shaft since there is a grease flow groove cut into the support bracket allowing for lubrication between the support bracket and bushing. There would really be no way for any sort of lubrication be get between the bushing and the stub shaft. I ended up purchasing two slightly used support brackets but I still have the issue of a loose fit on the stub shaft even with new bushings. There has obviously been some wear on the shaft. Landis Zimmerman told me they sometimes build up the shaft with weld and grind it off round so the bushing fits better but he also told me it is not really a press fit to either surface. Making up a shim could work except that the shaft is worn at the bottom and is not "round" anymore.  Any suggestions more than welcome. Seems to be a problem area on these machines.

They are about 1/8" thick. which is not much. There are grease fitting in the support bracket, but most that I have come across have never seen grease.

How thick are these bushings? Mine are no more than shim stock thick (maybe .020") and there is a lot of clearance, 1/8" all around.

For the EN the serial numbers should be 1B00 to 1B946. There is also a model EHG with serial numbers 1R00 to 8R52.  Both had Hercules OOC gas engines. Could your B be an R?

The sleeve is a press fit onto the sub shaft.  They usually wear through on the bottom and split. The support bracket will wear out of round as you say. They can be repaired by boring them out until round again then adding a sleeve to fit.

Hi all, just wanted to check in and let you all know that I have just purchased a 1945 HG and am starting the process of restoring it. Been getting some parts from Zimmerman and they are such good to work with. Brand new to this site but hope that I can get some good info and possibly help with some. Been restoring old tractors for 30 years and just got my first Cletrac..

Hello everyone,

I am doing a little work on my HG 68 that I rebuilt about 10 years ago. I removed the inner track support brackets to check the bushings because the button fittings had plugged up on both sides on the inside. Surprisingly the bushings are in good shape. The bushings fit rather loosely on the housing stub and in the support bracket. Seems to me like they should be a press fit into the bracket. I am weighing options about how to modify them but wanted to get some expert advice before I proceed. There is an oil groove inside the bracket and a hole in the bushing but if the bushing is loose enough to spin then there is no way for oil to get the the surface between the housing stub and bushing. The bushing can't be a press fit onto the stub since there would be no way to remove it. Any advice or suggestions would be greatly appreciated. The wear on the bracket is on the bottom end which bears the weight so using an oversize bushing is not an option. Not sure if I could find two track support brackets that don't have any wear. I suppose my main question is this: is the bushing supposed to be press fit into the support bracket?

Thanks!

Things have been slow I thought maybe this would kickstart some discussion.

I am hoping to finish up my HG-42 and then finally after 10 years get to start work on my E-62.
