Timberjack 225 Transfer case identification

[vasquat]

I've attached some pictures from the plate and stamp on my transfer case.  Anyone know what this things is and where to find information?

The brake hub on my transfer case was leaking fluid and even after I filled it the unit braked poorly.  Upon taking the brake hub off I found it filled with grease.  I assume the seal on the transfer case output shaft is leaking.  

The ID on the existing seal is much larger than the spline shaft, but I see it presses against the annulus on the rear of the tapered roller bearing.  Is this how it seals? does this make sense, or perhaps it was the wrong seal.  

In terms of the brake fluid leak, it appears one side of the brake actuator is frozen, so it only presses on one shoe, and perhaps with the shoe being worn it extends on piston too far and leaks around the actuator piston.  Does this make sense, or is there another place I should check for a leak?

Thank you for the help

It might be worth calling Nash Equipment in Colebrook NH. They carry parts for TJs and seem to know them pretty well. I drove by the other day and they had half a dozen sitting on their lot.

The picture you have is of the PTO for the winch. If it is on a 225D Timberjack it is most likely a New Process transfer case. Newer machines may have a Eaton one. Better pic's would be needed to identify.

yes, it's a new process transfer case. I assume you took the castle nut off the back of the brake drum. Removed the brake drum to find the greasy mass. The piece which bolts to the brake drum with four bolts is what the seal rides against that you are describing. you're probably gonna need a need a seal and a speedy sleeve, so it won't leak and then remove all the greasy internals de grease replace brake shoes and probably the slave cylinder.
  I would either take the brake drum to someplace which rebuilds engines and can steam clean it or clean it yourself and then pack it in speedy dry to try and get as much oil out of it as you can. also look at that splined shaft, the brake drum mounts to to see if it is twisted at all. If the brakes are working properly, it is possible to twist that shaft off.  I don't remember what the bearing preload is, but I can look in my book in a day or so.  dont lose the castle nut either its some oddball thread  youll have a hard time finding one.
