Hi, 

I'm sure that this has been addressed in some form or fashion in the past but I can't seem to locate it.

Does anyone have a reference for modern bearing, race and seal numbers for the suspension on the weasels? Ive found the bogie seals with skf 12391. But can't find the bearings or races/cups.

Also looking for the same info on the idler and drive bearings.

And u joints for the drive shafts for that matter. Any help would be appreciated! Thank you!

The ORD 9 parts manual has Timken numbers......you should be able to find everything you need online pretty easily.

 

Thank you Patrick. I found those numbers for the bogie parts but nothing in the manual has a Timken or any civilain bearing numbers for the return rollers, idler, or drive parts. 

So the search continues....

FWIW - the early ORD 789 G154/179 does have the Timken Numbers....they are only cross referenced to the Group so the chart itself is not useful without the rest of the book - you have to go to the Group Number and locate the Timken Number there (usually in a parenthesis...)

 

Here is the download:

@04mustangAs an alternative to the return roller needle bearing, I have fitted bronze bushings. This mod was done to the Australian Weasels operating in Antarctica. This mod also allows you to fit a wider bushing (on one side only) to more evenly distribute the load. The take out return roller shafts that I have all show extreme wear in way of the needle rollers. The needle rollers don't take too kindly to lack of lubrication and being exposed to water/moisture. Just a thought. I have attached a couple of photos for you to study. Cheers

Thank you Sir!, I already had purchased it from you some time back, just didn't have it with me at the time I was typing yesterday. I spent some time a dug through both manuals and found the chart you referenced.  It is a bit confusing but I worked through it with the group numbers.

John, I have to ask, where did you find the return roller bushings and shafts?

I do believe I will end up needing to replace at least 2 if not all 4 of the shafts on my M29C because they appear to be bent from over tension of the tracks.

you can weld up the old shafts and turn them down.  I had to do this on several and works well. Also if not a machinist any decent machine shop can remake those shafts no sweat! Mine were worn where the bearing froze up and ate into the shaft.

I machined the bushings to suit from stock bronze. A very simple job for a capable machinist.
