Malfunction

Cause

Remedy

External leakage pivot box lever or

control kit side.

Worn spool seal due to mechanical

actuation or high back pressure.

Locate the leakage and replace the seal.

Check back pressure level.

Excessive internal leakage on A and B

ports.

Increase clearance between spools and

body due to high wear.

Replace the directional control valve and

check the oil contamination level.

Dropping load during transition while

raising

High leakage on the load check valve.

Remove the load check valve and clean

the seat, verifing it’s not dented.

Inability to build pressure on A and B

ports.

Pressure relief valve blocked open.

Remove and clean or replace the valve.

Inability to build pressure on A and B

ports.

Low pump pressure and flow.

Check the pump and circuit.
