Case 1835B chain case fluid running over

[aaa123]

Was helping a neighbor try to pick his kubota back up out of a hole and the skid loader was tipped forward hard. Suddenly couldn't move anymore, got out and saw a big fluid leak near the loader valve. Shut down and the kubota had to pull me around a little to where I could pick it up with the truck. Well, got the loader valve rebuilt and reinstalled and refilled the hydraulic reservoir. Also changed the engine oil and cranked it a bit without starting to prime the oil pressure. Now I noticed oil is running over out of the left side chain case cover. Removed the cover and fluid went all over. Seems the oil is pumping from the hydraulic reservoir straight into the chain case. I've never worked on the motors and chain drive. Am I right in guessing the drive motor seal blew out and is pushing oil into the chain case? Since I got the machine, one side has always been slower, and I think it's this same side. Thanks -Hans

Well, drained the chain case and waited while gallons of water poured out until getting some white oil sludge. Bad seal on the case cover and a lot of rain... And verified the motor is emptying hydraulic oil into the chain case so out comes the motor for a reseal.

Not a great feeling when you see while oil.
I don't know if this machine runs a seal on the drive motor of it its sealed on a motor carrier. Either way, the seal replacement shouldn't be too difficult.

Well, I figured out the problem... the nose of the motor is broken off, cracked right around through the cast iron. The machine went through hydraulic oil since I had it, but figured something was leaking under there but it was winter and couldn't work on it so I just kept it full. The pumps are dry and no obvious hose leaks, so here's where the oil was going. That motor was always half the speed of the other as well, so mystery solved. Was cracked and finally broke through. Don't know if that nose cone is still available or if I will have to spring for a whole motor. Yuk. -Hans

Ouch, at least the mystery is solved.
I'd suspect the part is available. You'd just need to fond a place that has them available. You can always try http://www.loaderpartssource.com/

Neither Coleman nor LPS could supply parts to fix it. I could probably braze the housing but no guarantee it would work, and getting it in and out of there is a bear. Gotta get this thing back together before winter and I don't want to have to pull that motor out again, so I bit the bullet and laid down the $1100 for a new motor from LPS. Ouch is right! Thanks for the help.

It does sting a bit....
I have to agree, if you welded it back up, whats to say it will not damage the hardness and cause it to fail again later. Its fine if you don't rely on it and as you pointed out, its a horrible thing to remove.
