Clutch won't disengage

Gazza1969 · Oct 11, 2022

Hi all. I have bought a universal farmliner 445c dtx8, not sure what the 445c dtx8 means?
The problem I have is that the clutch won't disengage. It has two covers on the gearbox. I have taken them both of and have sprayed WD-40 and brake cleaner in there with the clutch pedal down. Still won't release.
Tips and info of what to do next would be greatly appreciated.

Hmmm....need more information here.... Has the tractor sat for a long time prior to this happening? Does the clutch feel like it depresses?

Gazza1969 · Oct 11, 2022

The guy I bought it off said he parked it and the next morning would not disengage. How true I don't know.
Yes there is still weight on the clutch pedal

If the clutch acts like it is working movement wise and has a running engine prop the pedal down and drive it around in the field if it still is stuck check that the facings are what is stuck. IF the spline is stuck it will probably need to come apart to get loosened up. If just the linings then park it against a tree and let it try pushing the tree it will come loose or spin holes.

Thanks heaps caterpillar guy. Will give that a go.

Looks almost like a Fiat design. caterpillar guy is right but I would just start the engine and let it run for a couple of hours without clutch pedal held down to
prevent excessive wear on throw out bearing.

I've had luck getting them loose by jacking
up one rear wheel, blocking the clutch
down, putting it in the highest gear and
rocking back and forth on the wheel. That
gives a jerking motion that seems to work
well for freeing them. Some that have sat a
long time get stuck real hard tho. One 1030
I tore apart I had to destroy the clutch to
get it apart.

Wow ok. I'm so hoping this won't be the case. I'll take to shop as I'm not familiar with splitting a tractor in half. Sounds very heavy to do so.

Gazza1969 · Oct 11, 2022

I'll try that. Only had it running for 10mins. Thanks heaps.

BOILING hot soapy water works a lot of times.

If the pedal is not held down then the clutch is not going to come loose since it is being held tight to the flywheel. That is the reason for the blocking the pedal. Now for wear on the throughout bearing. If that wears out the bearing then the clutch needed to come out anyway. I've never worn a throughout bearing in all my life so far. I've had them go bad from lack of grease. But never wore one out. So if it is greased it would be fine for this issue.

I had a similar problem with a Ford 8N. I made a spray hole, tapped it and sprayed brake cleaner all over the clutch and flywheel. After a few minutes I started the tractor and the clutch was still stuck. So I got another can of brake cleaner and sprayed the whole can in there. Then I got a long chain, hooked it to the rear of the 8N and hooked it onto another tractor (Cockshutt 540). After clamping the clutch on the 8N down with a large clamp, engine off and gear shift in Reverse, I got on the Cockshutt and with a fair throttle I gave a big sudden jerk on that chain. That did it!! The big jerk with the spray did the job for me. Of course I then put a bolt into that tapped hole.
Hope that helps.

That happened to me. Parked it and it was
fine. Next morning it wouldn't let go,
hardly any pressure needed to push the
pedal down. Broken spring on one of the
pressure plate fingers. Started it in gear
and drove it to the garage.

(quoted from post at 17:15:14 10/11/22) Hi all. I have bought a universal farmliner 445c dtx8, not sure what the 445c dtx8 means?

I looked up the UTB Universal Farmliner 445 on google, and it appears that the tractor has a 45HP engine, so the "45" in the 445 is the HP of the engine.

The "DT" means it has MFWD (4x4, 4-wheel-drive, however you want to call it).

By looking at the top picture, you might be able to block/tie the clutch pedal disengaged, then rotate the engine and look for an opening in the flywheel to get a screwdriver in to pry the disc from the
flywheel. Did this on a 3020 JD.

The drive disk is the encased one not the one against the fly wheel,probably as said lock the clutch pedal down and drive a screw driver between the clutch disc and the steel plate.

Gazza1969 · Oct 12, 2022

Got the clutch held down.
I have seen on here an old post and they push it off a jack. Was thinking that may break something.

Gazza1969 · Oct 15, 2022

Pulled the tractor apart. Front fly wheel had alot of surface rust. However I don't know how to take apart the second half of the clutch. Any ideas? The plates seam like new. I'll post pictures. Thanks heaps.

I can't see any springs
