Gas engine power outputs must be approximately twice the pump power requirements shown above. We recommend a 1.15 service factor be specified when selecting an electric motor as the power source. To compute specific pump horse power requirements, use the following formula: HP = (GPM X PSI) / 1450 SPECIAL NOTE: The theoretical gallons per revolution (gal/rev) is 0.0089. To find specific outputs at various RPM, use the formula: GPM = 0.0089 x RPM P420A-3100/5100 PUMP PARTS LIST ITEM PART DESCRIPTION QTY.

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 socket wrench, remove the three discharge valve plugs and three inlet valve plugs (32). Inspect the o-ring (33) for wear and replace if damaged. 2) Using needle nose pliers, remove the inlet and discharge valve assemblies (27A). Note: It may become neccesary to remove the valve seat (27) from the valve casing using a slidehammer. 3) By inserting a small screw driver between the valve seat (27) and the valve spring retainer (30), the valve assembly can be separated. 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 125 ft. lbs. Use a 8mm allen wrench to remove the 8 socket head cap screws (34). Carefully slide the valve casing (26) out over the plungers. Remove the weep return rings (25). 6) Remove each seal case (20) with o-rings and oil seals (21 and 22) from the crankcase (1). 19 22 20 21 24 23(B) 2S 24 23 23A OO® GOO.
