Hydro Leak

[Martin Johnson]

I think I got lucky.
On my 149, I recently performed a hydro transaxle exchange, due to a massive leak. I just happened to have a spare; so while the purist would have repaired the original, I tried this first. Good news, most everything works as intended and I am using my 149 for fall cleanup.

I do have one minor performance problem, probably an adjustment issue. When going DOWNHILL ONLY, the 149 does a little bit of a donkey jerk. Perfectly smooth on level or uphill pulling. Any ideas?

But the main reason for my post is:

I do have a miniscule leak on this unit as well, and it appears to be from the hydraulic return tube connection. I could live with this indefinitely, but it seems it would be an easy fix. Problem is, I have tried to fix a similar leak before; and I made it worse. Of course I used some generic O-ring; plus as I recall it is a bugger to get this off with the hydro pump in place.

Please kindly advise on the proper method and parts.

Pretty simple, unscrew everything, replace bad stuff and screw it back together. BUT! If you want read about it and look at some pretty pics, the Service Manual can help you out with that. http://ccmanuals.info/pdf/1x8-9 & QL Service Manual.pdf
