Hydraulic Leak..

[duke7595]

I have a 2240 John Deere that is leaking hydraulic fluid from a vent located on the under belly, there is a cotter pin in this small hole where the fluid is leaking from. Can anyone explain what the problem could be?

That's most likely leaking from the transmission input shaft seal. Requires splitting the tractor in half to replace the seal. If it was black oil, it would be the crankshaft rear main seal.

Thank you for your reply. I was thinking maybe the filter screen and hydraulic filter may be clogged causing back pressure, however, you probably are correct.

The oil is black so must be the crankshaft main seal. What is the fix? Is it a big job?

Same deal. Split the tractor, pull the flywheel out, replace the rear main seal. If it has a loader, it's a bit more time consuming as you need to pull the loader mounts out.

Thanks for the info. Think I’ll send it to the dealer. Approximately how many hours would the fix take.

I don't really have a number on that.

I've split a small Kubota B7000 and put it back together in less than 2 hours, but that's a tiny tractor and didn't have a loader at the time.

Needs a special tool to fit that seal. It comes in 2 parts . The seal and a wear sleeve

Wonder could it be back feed from the backhoe.

I doubt that BH feedback is causing the hyd leak. How is BH hyd's attached to tractor hyd system?
