Hydraulic Oil

[BillC@8591]

Hey all, as I am working on my 1957 JD 320 U hydraulic system. I was wondering what is the best oil to use? The manual calls for 10W, which I assume was a non detergent back in 1957. I have been using that oil, but I have no more and it is not available. The hydraulic system is separate from the transmission and engine. I am about to take the hydraulic pump off and replace the o ring, so the oil from the hydraulic system does not leak into the engine. Thanks a bunch, Bill C.

I would just put regular tractor hydraulic fluid in it.

I agree with Phill
Tractor Supply has Traveller its a good brand

Scuse the ignorance, what is the definition of SCV?

Hey to all that made suggestions relative to a hydraulic oil leak I had from my hydraulic pump on my 1957 JD 320 U. I took it apart. It was a project. Spent more time taking everything apart just to get to the pump. Pump looked good. Replaced o ring. But the real problem was just behind the o ring was a leather washer. It was completely destroyed. Leak is no more. To the person that mentioned the o ring and the JD price of about $4.50, my JD dealer wanted $7.50 for the o ring. The leather washer was $9.50. Oh, the joy of living in Massachusetts. On to the next project.

Honestly I don't think that's too bad considering you got the parts for a 70-ish year old tractor from the ORIGNAL MANUFACTURER. People fail to stop and consider how many hundreds of tractor models have come and gone in that timeframe, and that Deere stocks parts for most/all of them!

Under $20? I wouldn't cry about that. Living in MA is what I would be crying about.
