Good afternoon brethren. 

I have a delemma. I have three GT14 hydro pumps, with rearend. 

I know the mechanical status of only one, the one I replaced on my running GT14. Although it moved forward and backwards, and had trouble going up a hill.

The other two pumps and rearends are on parts gt14s I bought. 

I have people asking if they're for sale. I don't want to sell them junk.

Is there any kind of test, or a way to check these for "good working condition"?

 

Thank you.

Sadly I do not believe it is possible with out them being hooked up to an engine.  Even if you rigged up some kind of belt to an engine all you would be able to test would be the charge pump pressure.  If valve plates were scored it wouldn't show up until you got it hot and put it under load

Manny, the majority of GT-14s were worked hard and the wight of the tractor and attachments took a tole on the Sundstrands. The springs on the acceleration valves break and cause poor performance. If the pump is good and the acceleration valves haven't been damaged a few new springs will make it like new. In my case the valves were destroyed and I couldn't repair it, but made a discovery.  A Charger, Bronko  or Electro will have the same transmission with the exception of the final drive gear ratio and tend to be in better condition. I took a unit that was known to be good and changed out the output gear to fit it to the GT-14. Here is a thread on how it is done.

No special tools needed and once you get over the fear factor of working on a hydro it is not too bad a job. Check the manual to see what I am referring to on the acceleration valves, if they are good the whole unit is likely to be good.

Hope this helps.

God bless you.

      GT14 (1970)
      By Rob R
      I finally broke something serious on my GT14 the Lift arm that is attach (by chain) to the plow snapped off at the receiver arm top which is attached to the Hydro cylinder on the bottom. It appears the broken arm was welded there (see pics) my big question is how do get the "H" arm which is mounted on each side of the tractor by the steel plates the go up from the tractor frame out. I took off the four mounting bolts for it but it is tightly fit in aforementioned side plates I can move it up and down but cannot get it out. Is it relatively easy to remove one of the side plates and if yes which side is the easiest the pedal side left side (from the back) or the right side (from the back). Has anyone from the square experienced this problem, does anyone have this lift assembly. Any and all comments welcomed. p.s. I have used this beast for 10 years with zero major issues guess the stress of the lifting finally got to the arm which obviously is under tremendous pressure......Rob

      K321 Condenser Location and Hook up
      By Rob R
      Hi Guys, got a K321 14HP Kohler in house with all the electrical components removed. I cleaned and aligned the points, added a 12v (resistor coil) positive 12V battery feed to positive terminal, ran a line from the negative side of the coil to the points. I know I have to add a condenser also to the negative side. My question is does location of the condenser matter i.e. next to the coil or is closer to the points better. Thanks Rob

      GT14/D series lift cylinder modification
      By tractorboy79
      I was looking around on ebay and noticed that hydraulic actuators from John Deere 312, 317, etc models appear to be Identical to a Gt14 or d series lift cylinder. My question is would a new cylinder from ebay be able to replace one that is on a gt14 or d series?

      69’ GT14
      By wh315-8
      I have a question about the 69’ model. I took my tank out to work on carb easier. A couple weeks later as I put it back together & after cleaning everything; I replaced the white weatherstripping that was at bottom of tank and on the corners of the strap. Seems to be all that holds it in place. Because the strap around the tank will not go around the metal bracket on bottom and fit the tank. And even if it did the strap would only line up with the bracket mounting bolts which would be in the way. What did I miss? Didn’t pay close enough attention when I took it apart and can’t see in the parts diagram where the strap does go around the bracket. The weather stripping is tacky enough that the tank stays in place and it is a made to fit perfectly in position. Just seems that the metal strap is pointless.

      Gt14 dash and control panel plastic
      By tractorboy79
      I have a old gt14 and the plastic plates or control panels are way past their prime, and I saw someone was remarking them with a 3d printer a little while back and I was looking to se if I could find the file but no luck. If anybody has info that would be amazing. Thanks for your time and anything helps.
