Last post by Robert Barbour - November 12, 2018, 07:35:23 PMWell Jack, that is a lot of work! But it should last a long if kept greased.

Last post by Jack in NB - November 08, 2018, 10:11:57 AMWent through three tractors with the problem 30 - 40 years ago. Built all up with brazing, Machined with fly cutters driven by electric drill for the casting (Pressed out the axle and inserted a stub armature) and drill press and jigs for the brackets. Added grease fittings to the 2 brackets with none on the the front. Not a precise job by any means (lots of holes from insufficient brazing) but hey - they hold grease and stop the flop and toe-in!
And it's likely given the ages they'll outlast the rest of the units - as well as me ! !

Last post by Jim Leap - November 08, 2018, 04:42:50 AMThe 50 weight seems to be doing a good job of lubricating the outside track support bushings. Wondering if I should switch to grease on those too for the same reason.

Last post by Robert Barbour - November 08, 2018, 02:19:24 AMYes. I would use grease there, as there are no seals to hold in oil.

Last post by Jim Leap - November 08, 2018, 01:12:43 AMJust bought some fresh JB weld this morning. Seems like the best option to me short of building a special bushing.
Worth a try anyway. Am wondering if I should switch out the button fitting for a standard grease zerk and start using grease on those inside track support bushings as opposed to the 50 weight I use on the other button fittings (rollers, idler, spring and outside track supports).
Thanks,
Jim

Last post by Robert Barbour - November 07, 2018, 05:03:29 PMThe 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.

Last post by Jim Leap - November 07, 2018, 06:01:07 AMIt 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.

Last post by Robert Barbour - November 06, 2018, 05:09:25 PMThey 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.

Last post by mikegt4 - November 06, 2018, 02:53:34 PMHow 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.

All Models Except HG, OC-3, OC-4 & General / Re: EN 4B 76
Last post by Robert Barbour - November 06, 2018, 04:21:44 AMFor 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?
