arms and travel look fine to me, but thanks for the input. The left pump is the one troubling, the right is fine.

Been trying to source a part number for the hydo unit left side

Cub calls it 918-05128B
Google that, also look at the label on the hydro case for the HydroGear model.

wow that is over my head for sure, but I did find the issue
the top of the left drive - where the cooling fan "axle" goes into housing - and that is where it is leaking, looks like a rebuild is possible according to video , but ...
so looking now for a left tranny

they are quite pricey I see, perhaps I can find a good used one, but does anyone know an individual or business that can rebuild the one I have ?

sourced a used one , and noticed this - is this a fill port for transmission oil ?

my old one, is leaking fluid , and if this is a fill port perhaps topping it off would get me through the summer. work on replacing when its not 95 degrees Thoughts?

I gave you the link to the service manual in post #11.

Just spit balling here but if you are trying to just get through the
summer. How about a fluid change to a heavier weight oil?
