7114 hydrostatic leak

Recommended Posts

DMKNLD
I'm new to this forum, which is a great info resource. My 7114 hydrostatic tranny is leaking fluid from the middle of the pump, (looking from the back of the tractor), above the fill tube, where it looks like there is a seal that is leaking. It takes me about 5 hours to mow my 3 acre lawn, and it leaks about 1/2 a pint or so during that time, which I refill after each time I mow. It doesn't seem to slip or lose power. Is this something worth trying to fix, or is my tranny on the way out?

Is it where the hydro pump bolts to the transmission? If so that should be an easy fix, just remove the hydro pump and use gasket eliminator (the gasket-in-a-tube stuff) and replace the pump.

Thanks for the response. Yes, the leak is indeed where the pump bolts to the transmission - I can see where there is a blue sealant where they meet that appears to be where the leak is coming from. Perhaps a past owner repaired this and now it's leaking again. Looking at the Simlicity parts page, it doesn't really show the trans / pump connection. I imagine I have to drain the hydo fluid from the pump and disconnect the lines that go to the hydraulic lift? Maybe something best left to a tractor repair guy?

You should be able to do this... draining is super simple, and I don't think you'll have to pull the lines off the pump just to replace the gasket material. Now, I can send you a manual but you'll have to determine if your hydro is the same as mine (from a 7000-series machine). Send me a PM with your email address and I'll send you the manual I have in .PDF format.

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
