Power Steering Oil Leak

rljohnson · Jul 13, 2016

I have a 1957 D14 that has oil flowing out of the power steering breather just in front of the radiator when the tractor is put under a load and throttle is nearly wide open. Any other time there is no such problem. I checked the oil in the power steering sump. The sump is 2.25 inches deep and there is 1 inch of oil in it. I assume half-full. What is causing this problem? The tractor runs very well otherwise. There are repairs that need to be made. I have already replaced some parts, others coming. Just replaced the rear rims and tires because of rust. My mechanical skills are limited. I grew up on an Allis Chalmers WC, a John Deere 45 and a John Deere 630. During the summer working at my uncle's farm, drove a D14. Your insights on my problem are greatly appreciated. Dick

is the breather plugged up?

Does the the oil you use say anything about "non-foaming"? One of my D14's has power steering and when I bought it there was a very faithful leak. I figured I had nothing to lose
by adding Lucas power steering additive. I have followed the instructions on the container and it has significantly reduced the leak and I never have the problem you're describing
even when I work the tractor hard at full throttle sometimes by the hour. That said, I claim no expertise on the problem in yours.

(quoted from post at 10:46:27 07/13/16) is the breather plugged up?

Thank you for that suggestion. No, the breather is functioning properly.

Excellent input. What oil do you use and how much do you generally put in the sump? My next move is to drain the sump and start over. Thanks for your help.

I can't remember without looking at the manual. I believe there's a gear directly under the fill opening. I think you're supposed to cover that with oil, by maybe an inch? Use any good hyd/trans fluid. Also- replace the suction hose- the clamp on hose on the side which connects two steel lines. It may be hard and allowing the pump to suck air, aerating the oil.

Before starting the Lucas oil I used to mostly use synthetic 10W 30 engine oil and regular 10W 30 oil. The bigger reason I liked using synthetic was because it stays thin in the cold
of winter. With the leak the power steering used to have synthetic became more costly over time. Now thankfully most of that challenge is in the past.
