If your lift is working well the pump is fine; read over the manual, especially page 48 in section 4.

Surge & ztnoo I found tag and tow valve its tight I changed fluid and filter it will go in forward ok.for a little while but it will not go good enough to pull a blade and it will not back up.I pulled the pump section off but can't figure out how to sepperate the pump from gear section unless its all the pump.I will try to down load pics if it will let me.thanks.it says its too big.how can I download pics.

If you are a site supporter it will allow bigger and more picture files . There is a link at the top of the forum on the main page .

Ok. Thanks sarge 

[Bubba KC jr 9]

Ok. Thanks sarge it is a 1973 but it has the flat head screw type tow valve and its tight.but it will barely pull for a bit then you have to get off the machine and walk beside it.I have another GET 14 with the same pump motor but the actual pump is different.I am thinking about changing it out and see what happens.Do you think that will help.thanks

[Sarge 3,463]

Might want to post up some pics , it makes it easier for folks to help you out . Not sure if the pump will interchange as there are at least 2 variations - just make certain to keep dirt out of the system as it doesn't take much to destroy the pump .

MODEL # s Early and late

 

So as far as model numbers of the Sunstrand the early model without the directional valve on top  [on my 1065 I just got]  is Model # 90-2019 serial 9347

I also have a later machine with the tow valve on top.

 

 I am not 100% sure that I have found the tow valve on the front simply because the slotted screw is not there and what is there is an Allen head. It looks factory, but after 50 years who really knows?.On the later model there is a solid plug up front, so I am encouraged that the allen head may be the tow valve adjustment There is no oil on the dip stick of the 1075 and i really need to get out the engine gun and clean it up, remove the filter and then see what is going on.

 The later model Electro 12  trans works well, but needs the same maintenance as it could have very old fluid and filter. I could easily understand that the control linkage could be worn enough [ on Bubba's machine] so the reverse is barely able to work. 50 years of operation and dirt could cause that

 

 Here is the bottom line. i am gonna finally bite the bullet and buy a support membership so I can post some pics. BTW the model # tag is located in front of the tool box and on the rear of the transmission. More later.

 

 Sorry I could not get the model number to my other Sunstrand, but that tool box is pretty stubborn in coming off.

 

OK, so now I am a supporter and feel pretty good about it!

Well ohiofarmer.mine has the flat head screw and it's tight.

Backed it out would not move at all,put new fluid,filter and drove it forward 100' then would not pull forward after that now no forward or reverse.

Going to try and change pump later and see what that does.

But thanks for your help

[Wheelhorsegt14 1]

Wow what a awesome group of people this is my first post and am having the same problem with mine. I have to say it is great to see people really go out of their way to help someone with pictures and every thing. Thanks guys know I have a great place to start.

I gave up and sold the whole shooting match everything associated with my tractor.

No longer own it.

But good luck to all you guys.

And thanks for all your help.

You shouldn't have to remove the fender. Possibly the seat, and the maybe apparatus that locks the seat in a fore/aft position to get to the tow valve, but you shouldn't need to remove the fender.

I have never had to do that.

The valve may be really stuck in whatever position it is now in, so it may take some real elbow grease and penetrant to free it up. It may have never been turned since it left the factory. If its a '69, 1-1441 model, that means almost 48 years at this point. That's a long time for any valve not to have been turned, one way or another.

 

Screwing the valve to the open position (tow) should let you push the tractor around, although at almost 900 lbs. "wet" with fuel, oil, and tranny fluid, it's still work. We're essential talking about roughly half a turn.

Screwing the valve to the closed position (drive) will allow the tranny to operate normally and it will be almost impossible to roll the tractor due to hydraulic resistance and pressure in the system.

So if I can push mine then the valve is in the wrong position? It takes some effort but I can push mine around.

My tractor has the battery under the hood and under the seat is just transmission and a bunch if hydraulic lines if I reach up under fender on left side I can feel what seems to be a part of transmitted that sticks out like a finger with what seems to feel like a flat headed screw with a straight screwdriver slot in it.I do know you can push it now its not easy but it can be pushed in what ever position the valve is in currently.after it warms up outside I will go out and use all this great information all of you have given me and also find the serial # and mod.# tag and get back with you all thank you all.

I uploaded pics.don't know if you can tell anything from them but I can't find serial # and mod # tag but its to cold.I will have to wait until it warms up.I don't have a garage to put it in.thanks.

This is awesome I bought this machine 3 or 4 weeks ago and it still has the same problem lol 

This is so cool i have to say I bought this gt14 a few weeks ago. It still has the same problem go figure I would find a blog about it. Lol

Is their a difference in the sunstrand and a hydrogear?

It was on the right hand side under the dash sir.

Thanks for your comment but I put a new belt on it and pensioner and spring are good.I am going to change filter and fluid to see if that will fix it. 

the replacement belt was 5/8 by 84.7 

[daveoman1966 3,760]

The GT-14 Hydro-gear power unit is made by Sundstrand.  Here is the tag.  Here is also why your tractor has no power...the brass piston slippers are probably scored and need refinished.  There are PROBABLY other issues as well and  it'd be a good idea to pull hydro pump from the Hydro-gear to have a look-see.  If your piston slippers are scored like this, MAYBE to just refinish them would solve your problems.  If not, then there are other issues at hand.

I have rebuild a few of these over the years and can provide pics internals and the issues you  may encounter.

I’m gonna jump into this old thread Bri recent got a 1-7441 GT14 and I’m changing fluids, filters, etc. so I know when it was last done. Unless I’m missing something it looks like the tow valve on mine is on the rear of the transmission case. Anyone run into this?

I’m sure somone more familiar with these transmissions will chime in but you’re better off starting a new thread in the transmission section. The tow valves I’m familiar with were on the top left hand side under the seat plate.

Nicely hidden there I might add I had to drill a hole in the sheet metal to get better access.

[JimSraj 433]

I’ll try to get a picture of it ASAP.

If it is on the back it is not the original hydro unit.  Someone swapped in an early Wheelamatic hydro from something like a 1075

[JimSraj 433]

That’s a good possibility. I found the tag on the unit and it’s a 90-1173. Original was 20-2062 if my info is accurate. Changed the fluid today and found it was oil not trans fluid so replaced with 10-30. New Stens filter as well. Guessing whoever swapped out the unit converted to oil for whatever reason. 

I’ve attached a couple photos of the unit. View from the rear and the from the top. I added the bolt bc I wanted to see if I could move the valve. Probably going change it to a roll pin so it stays put. 

Thanks again!

BTW, I see you are in NE PA, I’m just outside of Klecknersville in Northampton County.

[pfrederi 17,866]

That is not the tow valve that is the opposite side of the motion control.  1173 wwere use on  D series hydros and some C series hydros.  The motion control shaft was out both sides as the C series mounted differently than the D series.  This pump could be used in either one.  It also would be piston to piston unit and I wonder if the hydro motor was changed out (if it was they had to change the drive gear.  What does you hydro motor look like...  #1 hydro gear (what came on GT-14) #2 Piston to piston....
