This step will ensure proper fit, at the same time protecting the pump nonmetal parts (i.e., the elastomers) from cutting and scoring. 1. With a 22mm socket wrench, remove the (3) discharge valve plugs and (3) inlet valve plugs (32) Inspect the o-ring (33) for wear and replace if damaged. 2. Using a needle nose pliers, remove the inlet and discharge valve assemblies (32X). 3. By inserting a small screw driver between the valve seat (27) and the valve spring retainer (30), the valve assembly can be separated. 4. Remove the o-ring (31). Inspect all parts for wear and replace as necessary. Apply one drop of Loctite 243 to the valve plugs (32) and tighten to 59 ft.-lbs. 5. Next, use a 5mm allen wrench to remove the 8 socket head cap screws (34). 6. Carefully slide the valve casing (26) out over the plungers. necessary Check surfaces of plunger (16). A damaged surface will cause accelerated wear on the seals. Deposits of any kind must be carefully removed from the plunger surface. A damaged plunger must be replaced! 7. Remove the weep return ring (25), pressure ring (24), and v-sleeve (23) from the valve casing (26). Remove the v-sleeve (23A) from the seal case (20). Inspect all parts, including o-ring (21) for wear and replace as 10 9. If the crankcase oil seals (19) are to be replaced, they can be removed by prying loose with a flat screwdriver. Take care not to make contact with the plunger. REPAIR INSTRUCTIONS - P217/P218/P219/P220/P221/P227/P230 PUMPS 10. If the ceramic plunger pipe (16B) is damaged, remove the plunger bolt (16C). Discard the old plunger pipe (16B) and copper gasket (16D), and clean the old locktite from the plunger bolt (16C) and plunger base (16A). Replace the plunger with the new one and locktite the plunger bolt and torque to 220 inch-pounds. NOTE: If there are deposits of any kind (i.e., lime deposits) in the valve casing, be certain that the weep holes in the weep return ring (25) and valve casing (26) have not been plugged.
