3020 Fluid Leak

Wreckmaster · Nov 20, 2022

I have a 3020 John Deere and it has a fluid leak on the right side of the housing where the clutch would be. There seems to be a brass cap or something that is about an inch in diameter where the oil is leaking from. It looks to be the shaft that disengages the clutch. How can I repair this leak. I am hoping someone has a simple solution so I won t have to break this tractor in 1/2. I just bought this tractor and didn t know it was leaking as bad as it is.

You didn't mention if it has a synchro or
powershift transmission, but either way
there should NOT be oil in the
flywheel/clutch housing to be leaking out
past the clutch operating shaft. If
synchro, there's a removable cover
underneath. Remove it and see if oil is
trapped in there, or simply leaking out
the bottom. DON'T stick your paws up
there with the engine running or
cranking! Post back with type of
transmission and serial number/year, as if
synchro the PTO clutch is hydraulic on
the later units, adding a leak source.

It has a power shift transmission Hydraulic fluid is leaking from the spot I m pointing to. [/url]

Since it is a powershift there's no hydraulic PTO clutch in the bellhousing to leak.

The area where the oil is coming out is the end of the transmission disconnect clutch fork shaft.

Does the leaking oil look like dirty diesel oil or transmission/hydraulic oil?

Either the engine rear crankshaft seal is leaking or the transmission input shaft seal is leaking.

The transmission has a pump in the front with a shaft seal, a very similar setup very similar to an automotive automatic transmission.

One other thing to check, if something is leaking in the steering pedestal area the oil COULD follow the disconnect clutch rod, which passes through a rubber boot into the top of the clutch housing. They are usually decayed, torn, or mouse-eaten, making it easy for any stray oil from above to get in the clutch housing.

Probably one of the previously mentioned seals, though.

The oil looks clean like hydraulic fluid so I'm assuming its the transmission seal. So to repair this one, we must brake it apart right? Is there anything special that we need to keep in mind to do that? I have done a Super MTA like that but not a John Deere.

It does have an issue with the steering. The wheels do not always turn as fast as the steering wheel does. I've been told that the John Deere Dealer had to fix this problem. Do you know of any other way? Our dealer here only knows late model equipment. Only younger guys here. The last older generation guy retired so there you go....

Thanks for all of your help!

A split is pretty straight forward, there's the transmission disconnect clutch on the flywheel, and a single set of splines to match up with an alignment tool IF you inspect or service the disconnect clutch while you're in there.

As to the steering, special tools and knowledge are needed to service/adjust it. You CAN do it if you have a factory service manual AND several special tools/jigs and good attention to detail, but experience DEFINITELY helps.

As you said, not every dealer has an older mechanic with experience on them.

''tim s'', in Ohio, and a regular here, offers a service where he goes through them, reseals them and adjusts them, then ships them back

Hopefully, he will see this, if not direct a new thread at him.
