Single Access Cover Removal  Cover is o-ring sealed.  Remove bolts.  Lift cover straight off.

Check Valve Removal  Check valve modules.  Modules sealed by o- ring and secured by a retainer.  Slide retainer straight out of body.  Modules can now be removed by hand or with a screwdriver flat.

Check Seat Removal * Check seats are attached to the cage with a bayonet type locking system. * Check seats are attached to the cage with a bayonet type locking system. * Module is spring loaded- Hold firmly. * Module is spring loaded- Hold firmly. * Hold the cage in one hand, push the seat inward and rotate clockwise. * Hold the cage in one hand, push the seat inward and rotate clockwise. * ¾” M2 modules snap apart. * ¾” M2 modules snap apart.

Check Disc Replacement  Check disc and disc holder can be replaced as one piece.

Check Valve Reassembly Notes  Reassemble in reverse order.  Apply lubricant to o- rings.  If check retainer does not slide into place easily, make sure checks are seated properly.
