1. Prepare Fluid Plate Assembly for Repair,
page 80.
2. Remove the cartridge assembly by loosening the
valve housing (CE) with a 6 mm hex wrench and
pulling the cartridge assembly out of the base hous-
ing (CD).
NOTE: The retaining nut (CC) often loosens when
removing the cartridge assembly from the base housing.
Be sure to re-torque as described in step 4.
3. Inspect and clean the internal walls of the base
housing (CD).
NOTE: Be careful to not scrape or gouge the internal
walls of the base housing. They are a sealing surface.
4. Re-torque the retaining nut (CC) to 140-160 in-lb
(16-18 N•m).
NOTE: You must re-torque the retaining nut before you
install it in the base housing during step 5.
5. Install the new cartridge assembly in the base hous-
ing (CD), and torque the valve housing (CE) to
30-35 ft-lb (41-48 N•m).
NOTE: The valve seat is double sided and may be
reversed for extended life. The o-ring and ball must be
replaced. See instruction manual 308647.

Carefully handle the hard carbide ball, valve actua-
tor, and valve seat to avoid damaging them.
