INSTALLATION INSTRUCTIONS 4. Use of a dampener is necessary to minimize pulsation at drive elements, plumbing, connections, and other system areas. The use of a dampener with Giant Industries, Inc. pumps is optional, although recommended by Giant Industries, Inc. to further reduce system pulsation. Dampeners can also reduce the severity of pressure spikes that occur in systems using a shut-off gun. A dampener must be positioned downstream from the unloader.

REPAIR INSTRUCTIONS - P300 SERIES NOTE: Always take time to lubricate all metal and nonmetal parts with a light film of oil before reassembly. 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 24mm 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.
REPAIR INSTRUCTIONS - P300 SERIES 9. Remove the pressure rings (#24) and grooved seals (#23) from the valve casing (#26). Inspect parts for wear and replace if necessary. For P318 only, the spacers (#23A) can now be removed. 12. For all pumps (except P318), use a flat screw driver to pry the oil seals (#19) loose from the seal case (#20) . For P318 Pumps Note: Occasionally, this procedure can be carried out for P318 pumps.
REPAIR INSTRUCTIONS - P300 SERIES Reassembly sequence of the P300 Series pump 14. If the oil seals (#19) were removed, replace them with the primary seal lip (grooved side) towards the crankcase and the dust lip (tapered end) towards the valve casing (#26). Lubricate the seal before replacing. Install the oil scraper (#18) over the plunger. each seal case (#20). 17. For P318 only, place the spacer (#23A) (#23B) into the valve casing (#26).
