7119H Hydro

Recommended Posts

Wow, what a difference. I've had a slow seal leak from the trunnion shaft (Input)on my tractor for quite some time now. Yesterday, I drained the unit, replaced the seals and filter, then re-filled with Universal Trans hydraulic oil. Touch the lever and the tractor responds instantly. Have to be careful now, going from forward to reverse can actually lift you off the seat if you're not careful. And best of all, no more leaks. My garage floor is happy.

Gear Box? If you mean "bevel gear box", it might have stopped leaking because it's out of gear oil 8) - which is a disaster waiting to happen. and pretty expensive potentially, it depends. If you mean some other part, then I'm out to lunch; not the first time; but I would rather say something, rather than sitting here and awaiting the dreaded future thread possibility. B) Check oil level in bgb. Do you have a manual?

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
