[QUOTE="richard, post: 2214, member: 285"] My service manual doesn't show anything about the hydrostatic motor, only how to remove/install it. In fact, in that section it says "SEE THE COMPONENT REPAIR MANUAL FOR HYDROSTATIC MOTOR DISASSEMBLY AND ASSEMBLY PROCEDURE". So I called my local Bobcat dealer today to order this "component repair manual" and they were not aware of one. The parts department did fax me a breakdown of the hydrostatic motor for my particular model out of their parts catalog, which was very helpful (btw, I can scan these in if anyone needs them). Looks like the shuttle valve IS behind those two allen key screws Tazza was talking about....and it looks like it could all be repaired/replaced without pulling the motor. Well, according to the manual, my problem is now down to A: shuttle valve not working properly, or B: damaged valve plate seals in the motor. I was thinking...since it sometimes works and sometimes doesn't, then it must be the shuttle valve not working properly because it seems to me, if the valve plate seals were damaged it would not work at anytime. Does this sound logical? Goodtech must be on vacation.....I sure hope he has some insight. Thanks again for all the help. [/QUOTE]
