It is crucial to check the machine's serial number and the number of hydraulic ports (1 hole) on the old housing.
The housing works with the hydraclamp piston. Replacing the housing often involves replacing a damaged or corroded piston. It is also worth checking the condition of the hydraulic hoses supplying oil.
A faulty hydraclamp (leak, cracked housing) causes the kingpost with the entire backhoe attachment to slide sideways uncontrollably during work. This creates a huge risk to machine stability and the safety of people nearby.
The hydraclamp is a hydraulic brake that locks the lateral movement of the rear arm on the frame (slide). The lower housing contains a piston that presses the arm against the frame under pressure.
