Hydra Mac 8b

[trenaud]

Just bought a Hydra Mac 8b, used it for a couple hours and all of a sudden the right hand drive went crazy and now it's stuck is reverse as fast as it will go. The T handle will somewhat control the left side, but has no affect on the right side. How do I get to the control levers that are connected to the T handle? and also where do I put oil in the hydrostat? Thanks

Is it hydrostatic drive?
Sounds like you may have a linkage broken or stuck. Check from the levers to the pump, something has to be loose.
Sorry, i can't give details on how to gain access to the T handle controls, i have never worked on one.

i had one like that, what it was is on top the drive pump is a spline shaft sticking up, the connection to that shaft was slipping and sometimes it would catch sometimes not.
