Hello everyone, I'm after some help regarding a slow, weak & shuddering dipper arm when operating inward. The pilot pressure is within spec and the pump/motor is heavily loaded while moving the arm in the air. Pressure from the control valve to the ram is low so I'm assuming the problem is in the main control valve. The spools and relief valve have been removed and inspected with no clear problem evident. All other functions work perfect. The valve is a KYB - KSJ3106 Any help with this will be greatly appreciated - Thank you in advance!
