The multi-function valve cartridge is removed with a 1-1/4" (042 thru 100 pumps)
or a 1-5/8" (130 pumps) hex wrench on the largest hex on the cartridge.
Inspect cartridge for damage to parts and o-rings.
Install cartridge in multi-function valve cavity and torque to 66 Ft. Lbs. (for 042
thru 100 pumps) and to 206 Ft. Lbs. (for 130 pumps).

For pumps with an auxiliary mounting pad, remove the four screws holding the
auxiliary mounting pad to the end cap and remove auxiliary mounting pad.
Using a 10 mm (042 thru 100 pumps) or a 13 mm (130 pumps) hex wrench,
remove the six screws holding the charge pump cover retainer.
Remove the retainer and the charge pump cover. For pumps with an auxiliary
mounting pad, remove the auxiliary drive coupling.
Remove the charge pump shaft and charge pump drive key.
Remove the spacer plate(s) (which may be present in later production pumps).
Remove the charge pump outer port plate.
Remove the charge pump gerotor assembly.
Remove the outer eccentric ring and alignment pin.
Remove the inner port plate.
Inspect the port plates, gerotor assembly, bushing, and charge pump shaft, for
abnormal wear, damage or foreign material.
NOTE: If a different displacement charge pump is being installed, the gerotor
assembly, gerotor outer eccentric ring, and inner port plate (earlier production
pumps) or outer spacer plate(s) (later production pumps) must be replaced
together. If different thickness port plates are included in an earlier production
charge pup assembly, the thicker plate is the inner port plate (installed next to
the pump end cap).
Prior to installation, apply a small quantity of petroleum jelly to the I.D., O.D., and
side faces of the gerotor assembly.
