I have a 1150 e case and while using it today Trans fuild began pouring from somewhere that appears under the battery compartment. It only leaks when in gear. Any ideas what this could be? Thanks
You are going to need to pull the batteries and plate that the batteries sit on, and maybe the seat pan and seat. Set your parking brake, Hook your batteries up with the link strap to be able to use a heavy duty jumper cables to start your engine, 24 volt. Use care in shifting the trans control leavers in case the parking brake won't hold and look for leaks. You have a lot of hoses that come off of the trans control valve, the control valve and tubes that may have a o rings, fittings and gaskets leaking. This is the brain area of the trans and the pressure is below 400 psi, still enough to cause injury, so wear your safety glasses, and don't grab any hoses that may be leaking with your hand. The small hoses lead to the brakes, high and low range, clutch packs, and will require the rear panel, counter weight, floor boards to be removed to get to the other end of the hoses if one are leaking. It could be the pressure line to the dash gauge also. Big thing is to make access see if you can find the leak area, pressure wash and repair. They are not bad to work on just be careful putting it in and out of gear while standing on tracks or behind them. The seat is a real treat to handle also. Let us know what you find, could even be some leaked battery acid has causes a tube to get a pin hole, my guess trans hose off the valve or hose to dash pressure gauge.
Thanks. It's a big leak should be easy to find once I get it opened up. Won't have time to work on til Monday. Will let you know what I find. Thanks again.
just wondering have they changed much from the 1150B
Had a similar thing on a 1150C, caused an increase in converter temp, turned out to be one of the gaskets sandwitched between the valve bodies that make up the main transmission control valve unit, leaked to outside at the rear. Not too hard to fix, as long as all hoses etc were marked for reassembly.
I took everything off like you said and found a leaking hose that came off center of control valve. It is easy to get to at control valve, but it connects somewhere in the front of the transmission just under the shift levers. What is best way to get to the hose to remove? Thanks
As sheep foot suggested, floor plates, possibly belly plates to get in from underneath.
make like a octopus The lines to the front side can be a little hard to get to. Once again with the seat pan and floor boards out, rt side fuel pedal pin can be a pain, if it has a cab more pain. You have to get yourself side ways and reach down under the shift tower to loosen them up. There will be some P clamps on some of those lines that will have to come loose depending on which ones. Be careful to not bend those lines (old ones) to much as they also may start leaking from the heat and age of that machine. I have a large selection of angle wrenches, crow foot wrenches and even with the correct tools some jobs are just bad. I have been stuck before with a cramp working threw the floor boards. It's kind of a bad spot with not enough tracks to kneel on. A pick up with some pallets and a sheet of plywood backed up to the track may make it easier, The service trucks you could place two 2x12 from the tailgate to the floor board and lay down. Have you a helper around if possible, keep oil wiped up on the tracks to prevent slips. Tag or make your lines, The smallest line in the center of the valve like said runs across and up behind the dash (engine side) it's around 80 inches long and leads to the dash pressure gauge. Like i said, make like a octopus!!
Thanks sheepfoot. Had to take a break had some sickness in the family. Your advice was exactly right. Was able to reach through after removing floor boards. Had to remove front hose to get to the broken one. $25 hose and $50 Trans fluid. Many thanks
