Rebuilding idler wheels off tracked tractor

In this video I rebuild and repair idler wheels from a Trax master tracked tractor.
The idler wheels had run out of oil and had destroyed the bearings and also the shaft that holds the wheel on. The customer had managed to find some new wheels but unfortunately, they were the wrong overall diameter, they were unable to find the ones the right diameter so a repair was needed on the old wheels.
After knocking the old bearings out, it turns out the centre bores weren’t too badly damaged. One side of one of the wheels had damaged where the circlip groove was but the other was okay.
The damaged wheel was put in the 4 jaw chuck in the lathe and over bored, it was then rebuilt back up with weld and the circlip groove was re cut.
The wheels could then be rebuilt with the new parts out of the wheels that were too small, luckily the parts were interchangeable with a bit of modifying to the shafts.
My new Siegmund 8.7 extreme system 28, 3 x 1.5m fixture table also arrived this week so that was unpacked and put together. Already came in useful for these wheels.

Hope you enjoyed the video
