Position new body gasket and the two o-rings and press pump body together. Reinsert air "in'' fitting, discharge and suction fitting into pump and
slide retainer clips over fittings until they snap into place. This will help hold the pump together during assembly.
Lubricate and carefully reinsert the drive shaft through the pump body. Install new diaphragm and piston assembly onto drive shaft and hand
tighten. Note positioning and direction each part is facing.
Position end caps onto pump body. Insert body bolts through pump body. Install washer, split washer and hex nut on each bolt.
Note: Remember to insert mounting bracket into niches on the body before installing end caps and bolts.
With a 5/16" (8 mm) nut driver, alternately tighten each body bolt maintaining even pressure around pump body. Using a 5/16" (8 mm)
torque wrench tighten body bolts to 20 inch lbs.
