Some things to check might be:
1� Steel lines and fittings�
2� Welds (Base to cylinder barrel)�
3� End gland of cylinder�
4� Cartridge O-Ring�
Internal leaks are more difficult to find and almost without exception require cylinder removal� Three
items must be checked to isolate the leak:
1� The load holding cartridge�
2� Stop engine� Activate outrigger control handle to relieve trapped pressure� Disconnect extend port
hose at valve�
3� If oil runs out of the extend port, the cartridge is bypassing and must be replaced�
TO CHECK LOAD HOLDING CARTRIDGE:
1� Raise truck off ground until tires are clear� If possible, apply maximum payload to flatbed
2� Stop engine� Activate outrigger control handle to relieve trapped pressure� Disconnect extend port
hose at valve�
3� If oil runs out of the extend port, the cartridge is bypassing and must be replaced�
TO CHECK STOW HOLDING CARTRIDGE:
1� Fully retract cylinder�
2� Devise a means of externally trying to extend the cylinder� (Porta-Power or Block & Tackle)�
3� Disconnect retract port hose at valve� If oil runs out of the cylinder, retract pressure port� The stow
holding cartridge is bypassing and must be replaced�
TO CHECK CYLINDER PISTON:
1� Fully extend cylinder�
2� Remove retract cartridge� Use caution, as there will be trapped pressure behind this cartridge�
3� Pressurize extend port to full system pressure�
4� If oil runs out of retract cartridge bore, piston is bypassing and cylinder must be serviced�
REMOVAL & DISASSEMBLY OF MAIN OUTRIGGERS
1� Extend the outrigger until the shoe just touches the ground�
2� Remove the snap rings from the link pin at the outrigger leg� The pin should drive out easily if the
leg is properly positioned� If the pin does not drive out easily, reposition the leg so the pin is not
loaded� Allow the links to swing down after the pin is removed�
USE A HOIST OR OTHER SUITABLE LIFTING DEVICE TO SUPPORT THE LINKS�
DO NOT LET LINKS “FREE SWING”� DAMAGE OR INJURY COULD RESULT�
3� Disconnect the outrigger hoses, after marking for later reinstallation� Cap hoses and fittings on
cylinder�
