Lucas CAV DPA Back Leakage Valve and Sealing Washer - Replacement
Because the valves are installed 90 degrees to the pump axis, the pump may need to be removed to change the valves
close to the cylinder block.
Caution: The installation torque is very critical. Overtightening can distort the bore in the pump
hydraulic head causing the rotor to seize in the bore. Never tighten the valve with the engine running.
