2520 power steering

Chris2520 · May 30, 2008

I always notest as the tractor gets hot my 2520 power steering is not as strong as it is when cold. i dont think nothing is wrong cause its been that way since it was new. it has 60 hours , and its still the same. when its cold. it steers easy even at ideal. and hot you need to rev up to at least 1000 to 1500 for it to be easy to steer. i know the fluid heats up. and gets thinner i am sure. I am fixing to do the 50 hour service. is there a better grade of fluid to put in than the JD fluid that came in it. i live in GA and its hot here we dont have much winter. and in summer its 90 degrees all the time.
anyone else ever notest this?

Cold oil = more pressure. Once warm, just bumping up the RPM as you do is the right thing. 1000 RPM is pretty low anyway.

JD Hy Gard is one of, if not the best, non-synthetic hydraulic oils out there. That and the Plus-50 engine oils are engineered by JD and are very good. Not just JD branded "regular" oil. I'm not saying JD makes oil, just that it is JD's special spec for anti-chatter, anti-foam, shear properties, etc.

Chris,
I would stay with the regular Hy Gard hydraulic oil from JD, not the Low Viscosity stuff.

in other words its never going to steer easy at a ideal hot..

Now you can trade without feeling guilty. JC

Not exactly what's been said, it's never going to steer (or do anything) well at "ideal hot" and idle RPMs. If JD doesn't want the engine sitting and doing nothing for extended periods at less than 1200 RPM I wouldn't expect it to do any real work at those speeds. Bump it up to 1750 or 2000 RPM and you should be fine.

Chris, my 2305 doesn't steer good at idle cold or hot. have to get her above 1500 rpm to get the pump going good. BTW, I just did my 50 hour service, be prepared for sticker shock on the hygard! a 5 gallon bucket was $60.

$60.00! Hate spending money on something you can't see. LOL!
