1250 transmission leak. Need help!
 

1250 has a slow leak somewhere on transmission. After about a week has a puddle about the size of a coffee can lid under it. Can't seem to see where it's coming from. Any suggestions where the likely source is? I will take off fenders to get a better look. If it's a gasket, please leave part number so I can look it up on an exploded view.
Thanks

It is most likely one of two things. (A) The cork gasket between the Hydro Unit and the rear end, or (B) an "oozing" Relief Valve(s). Pull the Tunnel Cover and inspect the Relief Valves first.

I was able to find mine by wiping clean, waiting and finding wetness with finger or paper towel. But someone suggested cleaning the area and dusting with baby powder, to see the leakage path. My leak end up being the round sheet metal plug, above the filter.
Good luck!

Thanks R Bedell. It's not the relief valves for sure. Hopefully that cork gasket isn't too difficult to change?

Thanks Andrew. That powder trick seems like a good idea. How did u fix the leak?

I've done it twice now. Is pretty easy once you get the tractor split.:beerchug:

Do I have to worry about parts flying everywhere when I split it?

If you have not downloaded the manual I suggest that you do so.

I also suggest that when you have the rear out to replace the cork gasket, If your tractor has internal brakes, is to check for leakage in the area around the plunger that goes inside the housing, the o-ring on the plunger can fail and leak.

I split the Tractor as desribed in the manual, then removed the old sheet metal plug. Carefully cleaned the hole, put tiny amount of oil resistant permatex and gently hammered new plug flat. I also replaced the internal brake oring, as suggested above. I found that I could grasp the rear side of the piston with needlenose pliers and sort of carefully twist it out. That saved quite a bit of transaxle disassembly. Note that to remove these thing the fluid must be drained, so it is a great time to change the filter, fluid, etc. Also, to be in this deep, it is a good time to consider the trunnion fix, if you need that, as I did.

Good luck.
