JD 60 Power Steering

[sheibult]

I have JD 60 (Serial #6062360) with non working power steering. The pedestal was leaking, so I pulled it apart, put in new O-rings, and filled the system w/ JD power steering fluid. My hope was the power steering was not working due to very little fluid....unfortunately not, there is ZERO assist from the pump. My multi part question(s) is:

1. Any ideas to pursue before jumping to a failed pump
2. Does anybody have a spare screw that is removed to test the pressure. This one was broken off....I was a able to get it out, but am curious if it is seating too deep? Does it bottom out or sit on the bolt head?

Thank you in advance.....any shared knowledge is greatly appreciated.

A few years ago I took that bolt out on my 630 and installed the homemade adapter and gauge to check the pressure. When I was done I screwed the bolt back in and I had no power steering. I think that I had to remove the relief valve, screw the bolt in and then replace the relief valve and then all was well.

I think this is exactly where I am at....the screw was originally "set" down the flow control valve and limiting movement. It appears this screw needs to be on the cone side of the valve. Does this match your experience?

It's been several years ago, but I think that when I removed the screw, the internal spring pushed the plunger and blocked the threaded hole that the screw fits into. It was an easy fix.

Yep, Mine sucks engine oil into the power steering through the fan shaft. I might have more than one issue going on but regardless I'm going through the whole assembly some day.

I have a 620 that sucked engine oil into the power steering to the point that it overflowed out the power steering vent. What a mess that made.

That's exactly what mine's doing. Couple years ago I had it running on the elevator for ear corn and the next day I checked the engine oil and there was barely anything on the dipstick. Thought maybe the RH crank seal started leaking. Didn't think much of it until spring when I checked the power steering fluid and it was way overfilled and starting to come out the breather.

The ball bearing in the pump had come apart.

Power steering is back up and running.... Thank you all for the input!
Now I have a PTO seal job that got bigger.... when I pulled the shaft out to remove the snap ring, the coupler on the end of the shaft came loose and fell to the bottom of the rear end. Something to do on a cold day, I guess!

What pump seals did you use, Deere? I see that Green parts of VA has the original "wide" seal and looks to be a better design than the replacement seals from Deere. I'm in the process of doing my 630 as we speak.

I just have the single seal replacement....although i am tempted to stack (2). After loosing the coupling, I really don't want to risk another $70 gasket to reinstall the coupling.

Use two seals install them with back to back so one seals in and one seals out. Fill the cavity between them with grease.
