hydrolic trouble

[ghaney]

Hi everybody out there in tractor world.
I have a, i think its a 1955 model 60 john deere.
It has two plugs right over the power takeoff that covers the holes where you plug the hydrolic hoses in. It has a leaver that pulls up to relise those plugs or pushes down to lock them in. It has a flat spring with two short pins top and bottom that suppose to lock in to the plugs when you push the leaver down and i never had any trouble with it till last fall. But now every time i raise the three point hitch all the up it blows the top plug out and all my 18 dollar hydrolic fluid . I don,t know if im getting back presure or the pins not holding.
anybody got an idea?

first thing I would check is to see if the nut that holds the lever and spring has backed off. could be that the pin is not being pushed in far enough to index the groove in the plug.

I have what I think it’s a 1955 model 60 john Deere.

It has a flat spring with two short pins top and bottom that suppose to lock in to the plugs when you push the leaver down and I never had any trouble with it till last fall. But now every time I raise the three point hitch all the up it blows the top plug out and all my 18 dollar per gallon hydraulic fluid. I don’t know if it’s back pressure or the pins not holding.
Anybody got an idea?

Have you tried swapping the top & bottom plugs?
We are assuming you have the plugs installed and not a hydraulic cylinder plugged in there at the same time?
Tractor ID should be on a serial number plate in front or below the belt pulley.
Have you checked the hydraulic relief valve pressure setting?

What he said PLUS... I've seen the flat spring crack to one side of the mounting bolt's hole. That leaves the spring too weak to do it's job well & they will do exactly as you say even if the nut has not backed off! Just replaced that part on my 44 hand start this spring for that very reason. Ran out of oil (dead spots in the yard prove it) just from plowing the garden!

I would replace o rings the are 2 small diam. and one larger in eash plug hole if the rear small ring lecks the plug act like a piston and blow out

If you have a cylinder plug with a pipe plug in it the plug will blow out because the cylinder plug has a tapered edge where the spring loaded pin rests.This is designed this way to allow the plug to pop out if it has to (ie. as when a plow breaks away) The right pin (also known as a dummy plug AA 4981 R) has a squared off groove so the pin can't pop out.This pin is nessary when using the rock shaft.

Thank you for that bit of sarcasm. Anyway i tryed swaping plugs and it still blew it out and no i dident have the hoses hooked up at the same time because it imposible to hook a hydraulic cylinder up to the tractor while the plugs are in. And the the tractor i.d. isnt going to troubleshoot this problem fo me.
Oh by the way buickanddeere when a man does or sayes somethng in life it will sometime or other come back around to you and when it does then you,ll know what its like to be called stupid. Personaly i think your a jerk. I hope i spelled that right.

The cracked spring sounds like a good idea. Thats the only thing i havent tried. That sounds like a possible problem. I will try that and let you know the results. Thank you. ghaney
