Old thread, but hoping for some insight.
I have a S60XL with GM-181 engine and the starter leaks. I've resealed it and after sitting three days it will begin a very slow drip. When the lift is running or sits less than three days nothing and if the lift is run and then the starter is pulled the fluid level is below the starter. This indicates that the jet or scavenger pump is working. So, how is the fluid draining back into the bell housing. On diagram I only see hydraulic pump and oil return line from the steering. If pump was leaking then I'd think it would be a bigger leak under pressure and I'd have a hydraulic issue. Lift works fine and pump is quiet. That leads me to think it's draining in to the bell housing through I the steering return line. This appears to be an issue with the GM-181 engine H and S series Hysters. Please is anyone has figured this out fill me in on the cause. Thank you
We have a lift like that. The starter went out on it and I figured out the flywheel rides in oil. Replace your starter and seal it ( the starter) with silicone. Be sure you clean all surfaces. I had to do mine twice. Good luck
got a GM engine in it?
if so the best i can tell is that this system is fed by a return line from the steering orbital valve going to the bellhousing, the 'scavenger tube' as he put it feeds back to tank. It circulates hydraulic fluid through the bell housing to keep the pump drive chain wet for lubrication.
As for how much fluid is supposed to be in there? Well it would only stand to reason that it will maintain a certain level if the return line is functioning properly, what that level is i do not see any references to this. If they hydraulic pump happens to be leaking into the bellhousing i don't see this as any problem other than it may cause some pressure build up which might be the cause of the starter seals being blown out? causing the leak?
Not really sure how to test for this though unless you have a way to remove a bolt or some other plug gaining a clear access to check internal pressure while the engine is running and hot to see if there is much pressure inside the bellhousing after it runs a while. I'm sure there will be some pressure but how much is the real question.
If the pump is leaking bad enough it could fill the bellhousing up too quickly and the scavenger tube would not be able to keep up with the amount and allow the compartment to fill up too much.
Is this unit a manual shift trans?
this would not be the first time a hydraulic pump had leaked into the bell housing.
That is how it appears to be. Without pulling the pump assembly off I do not know for sure.
May this truck have a hydraulic pump that is driven through the bell housing?
The hose that goes to the top is the scavenging tube hose. It catches the oil slung by the spinning torque converter and returns it to the tank. Not sure about the XL model, but the older machines had a way to unbolt that and adjust it. If you can take that off, check it, but something tells me that on the newer machines you can't access it.
Not that I have seen. There is something called a scavanging tube that I keep reading about that cracks alot and will cause this issue. But I think the trans has to be pulled to get to it. Also, the hydraulic pump is mounted to the bell housing. It mounts from the engine side of the bell housing. Could there be a seal there that is leaking?
Sounds like the return from the bell housing is clogged- there should be about 2-3" of oil in the bottom of the housing- it shouldn't be full. I'm not familiar with your exact machine- are there any other hoses coming off the bell housing other than the one on the top?
I had the back end of the lift raised about 10 inches off the ground and about a quart or so of oil came out of the mounting hole on the starter when I removed it. I lowered the lift and returned the next day to quite a bit of oil on the ground. Is there a place or way to check the oil level? I heard it was one of the bell housing bolts but do not know which one.
When you removed the starter- where was the level of the oil in the bell housing?
repair the starter
replace the mount gasket when remounting
job done
nothing else to do
IT MIGHT BE NORMAL FOR OIL TO BE IN BELL HOUSING STARTER IS BAD.SEAL IS BAD IN STARTER.WHAT TRUCK IS IT
