DMKNLD 0 Posted June 14, 2009 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? Share this post Link to post Share on other sites

RayS 81 Posted June 14, 2009 Is it the seal on the pulley shaft? Share this post Link to post Share on other sites
OrangeMetalGuy 41 Posted June 14, 2009 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. Share this post Link to post Share on other sites
DMKNLD 0 Posted June 14, 2009 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?

OrangeMetalGuy 41 Posted June 14, 2009 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. Share this post Link to post Share on other sites
