Is anyone able to post .pdfs of the service manual pages related to removal and service of the real axle assembly?
Parts list, exploded views etc.?


I drove through into a hole, nothing huge, something hung up a bit,, and right after axle is loose and leaking oil. I hear something broke internally.

I really would like to do repair myself, as tractor service is incredibly expensive, and I do not trust the quality and and skill of the service.
Much appreciated.

Thanks

Worse!!
I'd consider buying an insurance claim, (fire etc.) on a Max 28 or 28 for the parts.

Ouch, that looks like an expensive piece of casting.

Hopefully you can get one this year?
I would sell the tractor soon after.

Too many mods and accessories to sell.
A bit more Iron thickness around the bearing housing would have prevented this.

If I owned an aerospace NC machine shop, I could sleeve it with a very complicated sleeve I could design using SW so it would be stronger than a new Housing.
The programing and set-up would be a killer. $$$$

The Axle lock dog is just cast iron crap. Should be hardened steel. No wonder, it was so piss poor to engage. May repair it by welding up some hard facing build up and hand grind.

I'll replace the bearing that go a bit of metal in it.

Damn, this is going to be a project.

Wow, that is unfortunate. I tell you, after seeing all the problems my neighbor has had with his Max 28, I would never recommend that model series to anyone. Since they are Mitsubishi made I had expected them to be good, but they are just not well made compared to other models and brands. Wiring and hydraulics have been the typical failure points for people, so seeing this is a new one for me.

By the way, any theories as to how the load transferred to that spot to break there? Seems like the outer case didn't really provide any support to the axle at all? Was it a side load that maybe put a "thrust" on the inner bearing?
