I have an old skid steer (Bobcat 610) It is belt drive with 4 clutches. The clutches are getting worn and I would prefer not to replace all of them since it would be more than I paid for the skidsteer.
I am considering connecting a hydraulic motor to the drive system on each side and bypassing the old drive system completely, this would also allow me to use a variety of engines if mine ever needs replaced.
I know that ideally I would get a hydrstatic pump, or variable displacement pump. However, this is a project to SAVE money, not spend it.
I already have several gear pumps and a vane pump that I have salvaged from other machinery. I also have several matching spool valves (Gresen 400).
Question:
Can I use regular spool valves or do I need something with a variable control in order to get fairly smooth operation? What would you recommend? I am just afraid it will be stop or full speed with these valves and was hoping for opinions.
Remember, this is a 40 year old machine, so I'm not expecting it to operate like a cadillac, just functionality and safety.
