I recently picked up a Cat 235 and it doesn't have any auxiliary hydraulics. I would like to add a hydraulic thumb to it and so has anyone added auxiliary hydraulics to this machine? Or would it be possible to find the parts I need at a salvage yard? I haven't dont alot of research yet but wondered about putting a flow divider in the swing motor circuit so I would take say 5 GPM from the pump that operates the swing and designate it for a seperate solenoid valve to operate my thumb. Would this work? Anyone have any other ideas? Don't want to spend a fortune but want something that will work also. Thanks in advance for the help. Chris
