I figured the brake band failure and the cracked bevel gear drive hub/flange were all part of the same failure, man was I wrong.  The booger welds on this stuff just shows how bad some repairs can be.
The hub had been welded prior(really bad job) and the spackling they did on the brake band was pathetic.  Parts are and were when repaired still available even if used.

Like I said in my post on my D-15 engine, People should have to pass a test before being able to buy tools to work on stuff.

Yea, I can fix that.....

No kidding, looks like the welder was using JB weld for rod and put it on with a Q-tip dauber!  Somedays you just can't buy quality!
 
I do have the clutch release pistons out and as suspected the quad rings are quite trashed, doubt they would have gone any further anyway.  New and used parts on the way already and the rest of the machine drive train(Internally) looks OK.

This just goes to show you that most of the people who say they can weld CAN NOT, in fact they can get you hurt!!!!!!!!

Way back when I welded up a bunch of stuff for a guy on a stock car. this is when I was 16 or so and was using a old Forney welder and was using drag rod (7024) made a lot of sl*g and lot of smooth weld beads. 
 About a year later ended up taking the welded parts off the car, found NO penetration to welds and in fact with a sledge hammer every weld broke and once one did the rest followed with no trouble at all . (Ones is suppose to learn from mistakes)
 Now it seems to some I over weld or over prep things to weld but broken welds happen for one reason the time spent to prepare the job is shortcut ed  and the weld itself is not sound in good penetration and no voids. Cleaning and grinding as part of the process, sl*g removal, multi-pass and inspection are all part of the process. 

  (sl ag  wow a bad word I guess) 

That drive hub is one of the things one would not want to weld unless one machined it back to a true running piece as just the warping from heat and the stress that was put into it would create a problem. 
 I replaced 3 drive sprocket axles on my HD4 loader , well 4 if I count the last one i put in Original broke and i picked up the next form a guy not thinking it had been repaired , that one broke and i got a second one from him that also broke about a year later . On examining the 2 broken ones I noticed the weld at the break line and questioned him on it , seems he had a guy weld up bad seal area then grind it back into specification. The axle was not re-heat treated so became brittle at the weld point and a useless piece of junk. Rather than just use a speedy sleeve or other method they destroyed a part by fixing it by welding.

For all the trouble, to get as deep as you and I have been on these machines, why would anyone risk a cruddy weld job to have to go back this deep again in a business and have to fix it again as a warranty?  I couldn't even consider as a mechanic putting something like this back together EVEN if the customer asked me to, against my better judgement.

More time than money. I just took a TD14 apart to get a steering clutch free and throw some new tracks and sprockets on it, wiggled some stuff and guess what?
I'm going into the final drives, because I already have to get the trackframes and all off anyway.
(thank God I have a good set of final drives laying around so I don't have to buy them bearings)
I never understood throwing all that work away to have something that ain't going to last.

Many years ago, the place I worked at had an International T-9 that had sat for three or four years (enough to seize the engine and both steering clutches).
We bought a good used W-9 engine and tore into the steering clutches.  Had the new engine in and one clutch repaired and the owner of the place saw that we were spending time fixing it up.  He hit the roof and told us to put it back together and not to spend any more money at all on it.
We proceeded to drive it that way (steering only one direction) for the rest of that particular construction project.  For want of a few more hours, we could have had a good handling machine.  Instead, we had a pain in the you know what to use.
