TW-10 Hydraulics

KYCASE1 · Sep 8, 2019

Having problems with the hydraulics on a Ford TW-10. It started when I was baling hay and it seemed to have trouble opening and closing the rear gate on the baler, after a couple of times having gate troubles the hydraulics quit completely nothing would move on the baler and no 3 point. I put a gauge on the remotes and i have no pressure at all 0 PSI. Any ideas on were to start looking for the problem? I did change all the filters and it is full of hydraulic oil and no change. thanks

As abruptly as it happened I would bet on a bad internal leak as opposed to a bad pump. They are known, I believe, to sometimes drop the pump lift tube. Your best bet to get at it is to remove the top cover. You do that by taking the cab loose in the back only and lifting it about 6 inches. Then after disconnecting the external lines and removing the bolts you go in with your engine lift crane and lift it up and out. You need to be VERY careful of the linkage between the lift arms and the rock shaft. A shop manual is strongly recommended. You will probably get out of it for under $50.00 in seals etc. Also be very careful of the line for the PTO clutch.

How does it work with cold oil? If it works somewhat with cold oil, and gets progressively worse as the oil warms up, you likely have either a worn pump and/or blown seals in the pump internally. Both are accessed through the pump mounting side cover on the front RH side of the rear axle housing.

On the other hand, if you have nothing even with cold oil, you most likely have a stripped out PTO drive shaft internal to the transmission. This shaft drives the PTO clutch as well as the hydraulic pump. This shaft can only be replaced with a double split, as the hub in the flywheel will also need to be replaced. If the PTO still drives a load, discount this as a possibility.

Dropped pump lift tube? Sorry, that's pretty much impossible on a TW10, and even if it was, going through
the top cover would not give you access.

Thanks for the reply's. It does not work hot or cold and the PTO still operates as it should. Looking at the parts breakdown it looks like the gear that drives the pump is keyed. Is it possible that it sheared the key and the pump is not turning? I have not got into it yet so I am just pulling thing out of the air. When I find out what it is I will post back and let you guys know so maybe it will help the next guy. Thanks again for the help.

Yes, do let us know what you find. I'd be shocked if it was a broken drive key. I've worked on more TW tractors than I care to count, and I have never seen that type of failure before.
