Hello . I have cat 305ccr # cat0305cvhwj00557 while I was digging with it the control of the stick messed up and is trying to come towards the machine at all-time when machine is running even with the control lock up or down/on or off. What would cause that and how do I fix it. Does any one have a diagram of hyd system . Thanks for any help you can give me.
Sounds like the spool is stuck in the main control valve
Good day This can happen if the piston seals fail in the cylinder check for by-pass. Kind regards Uffex
