HD11E steering issue

Hey Guys. new to this forum but I have been following for about a year. I have a fiat-allis hd11e, ser. no. 11600, engine 10000 turbo. Wet clutch, wet brakes, direct drive, wet steering clutches. I have had a steering issue for some time. First thought it was a faulty pump and changed that. No help. Someone told me to put atf in it and it steered for about 2 hrs and quit.  Cleaned suction filter and it steered for 1 hr. Finally figured out fluid was so contaminated that after 1 hr run time suction filter clogged again. Cleaned filter again and steered for 1 hr. You can almost time it every time. Decided to change atf fluid again to get clean fluid in it. So 400 dollars worth of atf is now in buckets. After changing fluid this time it steered for about 3 hrs before it clogged filter.  After that it was back on the 1 hr schedule. No big chunks just real fine metal shavings that you can barely feel between fingers. So my question is

The right brake is a little sketchy. The adjusting bolt is loose even after trying to tighten it and the pedal goes to floor. Do I pull whole clutch pack to replace brake bands. How do I get all the metal shavings out of the system.

Once I get assembly out what should I look for in the way of steering clutch disc wear. Is there a stack height or just obvious visual wear? I don't want to have to do this again anytime soon.

Extremely rare for the oil clutches to need attention. As Hector says, the brake linings are the things that DO need replacing. They deteriate and clog the whole clutch hydraulic system

You mentioned fine metal shavings. How much had accumulated on the magnetic drain plugs in trans housing and bevel gear housing

Sounds like accumulation on bevel gear plug is just normal wear. The screen and filter blockages are likely to be small chunks of brake linings which break down with age. When you have the clutch and brake assemblies both out, and the top off the bevel gear housing, you can flush those compartments out thoroughly. At that stage, put a lever bar beside bevel gear to check for movement. There should be none.

razor i have figured out that I feel pretty good about tackling any project with the knowledge these guys on this forum have. 

While reading Dave`s post which reassures us that these ol girls will never be boring for us to play with, I realized I had forgot to mention another common cause of the blockages - deteriation of the rubber hoses throughout the system. Small chunks of rubber breaking away from the inner walls of the hoses, solved by renewing all rubber hosing from suction point to control valves, if it looks like that has not been done for a long time

Since you guys are so helpful maybe one of you can tell me what year this beast is. Ser. no. 11600. Couldn't find any exact info. Not a big deal. Just curious. I assume it is '74 or newer bcause it is fiat.

Sorry at beginning I said 10000 turbo engine I meant 11000

Ok dmiller. Thanks. Will get on it as soon as weather breaks

Is a newer group of guys at Kwik parts, Williamsburg MO, seem to find stuff I couldn't, may want to try them as well:

Thanks again dmiller

My HD7G had F/A decals even with AC on the engine and the serial plate so off that nonsense came. Found later it was a late chassis number so might just have had FA designation, still when repaint will only go back with Allis decals right or wrong.

I bet that is what I have. Michale34. It looks to have had a repaint in the past even tho it could use one again.
