Gt14 hydraulic hose looped front to back

[Webrx 0]

Hi,

new guy here. I have a few older cubs and a GT14. The GT was an engine and trans on a rolling frame so it’s mostly just a shell. 
 

I bought it for the engine but found it won’t work in the project I had. So, I decided to see if the trans works. My intent is to use it as a trailer puller and maybe do a little snow plowing. The pressure hydraulic hose was there but the return was missing. So, I looped the hose from pressure to return, replaced filter and fluids and put it on jack stands. Fired it up, had motion in fwd and reverse but the hoses leak pretty good. 
 

2 questions. 
1. is looping this hose going to cause an issue assuming I can stop the leaks. 
2.  Is it ok to plug the hydraulics off if I don’t intend to use them just now, assuming I can find plugs that are right size. 
 

thanks in advance for any info.

Our resident Sundstrand experts @daveoman1966 or @pfrederi should be along to help. in the meantime take a look at this manual.

Welcome.   You have a Sunstrand  Hydro gear system.  If you want to eliminate the hydraulic lift You need to make some changes to relief valves.  You will remove the implement lift check valve and move the charge pump relief valve over to that position and plug that port.  Do not just plug ports. Look a page 35/6 in the manual provided above. I am not sure if you loop idea will cause an issue or not.

Welcome

Ditto!

And be sure to hold onto any parts you remove! Many members work on Sunstrands, some converting the other way (to ADD hydraulic lift) and look for parts!

I would think the loop should be fine as that is really what happens with the lift valve plumbed in as the oil passes through the valve and back to the return when it is not being actuated.

 

Your leaks might be as simple as needing new O rings on the hose fittings.

Looking at Cleats reply and thinking on it he is right the loop should not cause an issue...

 

If it is leaky hose ends you could try replacing the O rings  Sometimes it is the swivel itself worn out..but it doesn't hurt to try the rings first. They are Dash #905 o rings.  PM me your address i can send you a couple.
