5.2.2 CARTRIDGE VALVE REMOVAL/INSTALLATION
WARNING!
Never remove a valve when the truck is running, and PTO is on.
When installing cartridge valves do not over tighten. Follow torque recommendations below. Over tightening
can distort cartridge body and cause the spool to stick.
Ensure that safe cleanup procedures are followed. Removing cartridge valve coils will drain some oil from the
system, so do not remove the cartridge unless you are ready to replace it right away. Re-fill reservoir to top up
oil level if required.

Remove cartridge valve coil and electrical cable.

Loosen the cartridge using the appropriately sized socket
or wrench for the cartridge hex. It is highly recommended
to use a deep socket to remove and replace the cartridges.
This will allow for much easier removal and replacement
including proper re-torqueing.
#10 size cartridge uses 1 1/16” wrench / socket (780657)
#12 size cartridge uses 1 5/16” wrench / socket (780658)
#10 size cartridge 54-61 N-m (45/50 FT-lbs)
#12 size cartridge 95-102 N-m (70/75 FT-lbs)

When re-installing the valve be careful not to damage the
valve seals .
