Engine drive shaft coupler to hydraulic pump failure. Need help!

[River Valley Landscaping]

I also have NH hydraulics sizing up a loader and lift cylinder seal kit and should be ready tomorow. I had one kit that came with the tractor when I bought it. I brought it to them to make a 3 more. It will be interesting to see what their price comes in at.

They tend to dry out when they sit on the bench for any length of time. Mine was fine before I had to take it apart. It sat for about 3 months while I managed to repair the coupler between the drive motor and the differential. When I put it all back together it leaked. First a little and after several hours of use it became a problem

Did you get the seal kit?

Hello: I think I have also stripped out my Kohler coupler.
How did you make out on your project?

I ended up pulling the pump and it looks like the spines at the engine stripped out.
The splines on the pump shaft look OK.
Next is to order the part from Kohler.
