GT14 Hydro woes

[flyovrcntry 115]

I have a GT!4 1969 model# 1-7441,I have only had it a couple months.I bought it with some riding mowers and was going to sell it originaly,but as I started working on it,I decided to hold on to it .When I got it it was leaking trans fluid out of some hoses so I fixed that and a few other items.I found a blade for it and when we had a few inches of snow I pushed it ok.Then the other day I went to push some of the wet piles and it just had no power in forward or reverse.There seem to be quite a lot of free play in the shift in the neutral position maybe 1/2".I forgot to mention that I changed the dex III fluid and filter with a mapa gold filter,I forget the # but I made certain it wa a hyd filter.When I first started running,the tractor the shifter would not hold position ,it would just move on up to the fastest position.I adjusted the tension as instructed in the manual and I think that helped.I guess I need some guidence,I know nothing about hydro's .So what would you do?

Thanks ,Bob

i dont know much about the gt14,but i would look into the linkage and where it connects to the pump,my c160 had linkage problems,i would replace the plastic plate that controls the pump,and it would strip,i had to shim the ball that fit into the plastic lplate,but i dont know about your setup,just start looking and hope that it is linkage not internal

flyovrcntry, #1 change the trans filter to a 79-5270 thats a Toro- Wheel Horse #. #2 it could be a couple of broken acceleration springs that could be a possible solution. That would be the first things that I would do. Check em' out. See ya, bye Burly

Are you letting the Hydro warm up all the way?

[flyovrcntry 115]

Yes I warmed it up real good,I guess I will take the linkage apart and look there first.I dont know what springs you are talking about so next I will look into that.

thanks for the replys

check the accelerator springs. they were shot on my GT14 and i replaced them and it helped a lot. tough part is finding a set. i replaced one with a known good unit but my reverse spring i grabbed one from the hardware store, it works but does the same thing you were talking about. it doesn't hold a speed in reverse. nothing in neutral then slowly speeds up to full reverse. So that being said, i would go for the springs. they are easier to get at than the linkage (in my opinion)

Could ou show me the springs you are talking about

Thanks Bob

when u move the speed control lever watch the action at the pump,is part #62 the plastic shifter plate moving up and down smoothly,sorry i dont know about the accelerator springs,your pump setup looks similar to my c160

Bob, here is what you want to do. Go out and take the left fender off where you expose the trans amd pump. You are going to find two large bolt heads which are

1 3/16" You are going to need to break these loose and behind that there are some springs. There are two of these bolts (One to the front side of the trans, for forward, and one one on the back side, for reverse) take apart one at a time works best. Remember how it goes back together. Should be a couple of springs behind each bolt. Let us know what you find. I have a friend that had these springs remade. I believe he gets twenty dollars a set. It is a whole lot easier with the rear fender removed. You can probably leave the kick panel inplace. Good Luck

See Ya, Bye Burly

[JUSS10 250]

i thought the front spring and valve was for reverse and the rear one for forward.... guess it doesn't really matter, just make sure to check both :banghead:

[Brrly1 1,146]

Yup, it really doesn't matter. I never have asked anybody, I guess it just doesn't matter. Check both. As a matter a fact, How did yours turn out Justin? See ya, Bye Burly

Bob, did you get your GT14 trans problem fixed? Also did you recieve the Email I sent you? This is my second attempt to respond. Could not figure out how to send a reply when I read your post. Newer type newbie here. Eddie

Thanks to everyone for the info

Did you change the springs yet out of curiosity I have the same issue with my 69 gt14 but forwards goes fantastic but reverse is very weak won't back up any kind of incline but forward seems perfect thanks allot

I'm having a hydo problem with my GT14. I took it apart and the strainer had red paint in it. Took the rest apart and found nothing. It has no power when it warms up. Any ideas ?

[953 nut 59,748]

  Juss10 is right, the one on the rear is for forward, but I agree with Brrly1 that both should be changed out. Mine were both broken although it was strong in Reverse and puny in Forward. You can download the Automatic Transmission manual on here and read up on it before doing the job. You will want to do them one at a time because the pistons are a little different, but do the whole job, not just the spring change out. By pulling the pistons behind the springs you make sure all of the broken pieces of the spring  are gone and the pistons will move. It they don't move then new springs won't accomplish anything.

 

Good luck and keep us posted. 

 

ps; take a few pictures and include them when you are done, it will help others see how simple this job is. The hardest part of the job is pulling the wheel and fender off!     

[fast88pu 3,370]

Mine has the piston style.not the hydro gear style. Checked the springs and they were intact and feel stiff still

[fast88pu 3,370]

Should it be able to spin the tires ? Mine had the ark loader and weight box on it and chains ?

[pfrederi 18,633]

My D200 with FEL was weak when I got her.  After overhauling the Sundstrand piston to piston she will dig the rears in with loaded ag tires and a counter weight.

[fast88pu 3,370]

What did you change out when you overhauled it pfrederi ?

[pfrederi 18,633]

What did you change out when you overhauled it pfrederi ?

Completely disassembled the hydro pump and hydro motor. Pulling parts from 2 other units and all new seals. Refinished all the slippers, valve plates, and swash plates on increasingly fine wet sand paper on glass and a lot more
