1964 John Deere 4020 Powershift hydr leak under lift lever

jguher78 · Nov 2, 2015

Have a hydraulic leak coming from the valve body under the lift levers. It looks like a 3/4 bolt head. Is there an o-ring that could be bad?

Are you looking at the power steering valve unit in the control pedestal?

Or at one of the "selective control valve" that are operated by the levers in the control pedestal, but are located under the rear of the hood?

I think 3/4'' size bolt head will have an o-ring or sealing washer under it.

It is at the selective control valve under the hood. Is it a pretty easy job to change those o-rings?

Yes one o-ring under a plug on scv is the same o-ring utilized on most older JD orb hose fittings. Part number is R26375
