Something is applying pressure to the control spool and pushing it out. That is why the lever went back. I'm thinking the TC unit has to come off and come apart for a good cleaning and rebuild.


It works perfectly now. I think there was just a bit of paint causing it to stick. I can't imagine what else. It works effortlessly with no hesitations or leaks. It stops where you want it in small increments. Couldn't ask for a better working TC unit.

Thanks for the help guys. I'll have to post a picture and video of it soon!

using cub today front blade was working ,then I raised it and would not go down . went to full up and then back down on control with no response. Noticed some smoke from breather ,drove to house and shut off. I then checked engine oil and found to be 1 inch over full. Checked hydraulic oil and cant touch with little extended in hole. suspect seal blown on hyd. pump. any ideas before I start is greatly appreciated. Grey Wolf

Overfull engine sump and empty TC reservoir are the classic symptoms of a leaking pump shaft seal.

redman36,

Just for future reference, rather than reply to a two-year-old thread with what is a separate (similar, but yes, separate) issue, you are free to start your own thread.

The main problem with dredging up old threads is people think they are new and start responding to the original post again most of the time.

Second that. In the future, please begin a new thread. Thanks!
