Cub hydro system

[OhioGuy]

Is there a website with good service info on the Cub's hydro system. My latest 1872 project (auction) is leaking a bit, I believe from the hydro relief valve. I'm hoping to power wash and isolate the source, but then what.

I noticed in the parts diagram there four different relief valves or maybe the ported and non ported serve a different purpose?

I hate oil leaks!

It also wants to creep forward, I guessing some trunnion adjustment is in order?


Thanks,
Curt

You can download the 1862 (very similar model) service manual here:

The hydro creep is due to the linkage to the pump needing adjusting, which is very common on older hydro tractors. The leaks are likely to be your typical seals and gaskets.
