GP7132 AND GP7136 REPAIR INSTRUCTIONS NOTE: Always take time to lubricate all metal and non-metal parts with a light film of oil before reassembling. This step will help ensure proper fit, at the same time protecting the pump non-metal parts (elastomers) from cutting and scoring. 1. Lossen screws (58C), take plugs (58) out of valve casing with two screws. 2. Take out complete valve (51) using either tool (part #07662) or stud bolt. 3.
GP7132 AND GP7136 REPAIR INSTRUCTIONS 8. Separate plunger (36) from crosshead (25) by means of one open-end wrench. 38A 38B 38 38B 9. Pull seal sleeves (39) out of their fittings in the crankcase. Take seal case (38) out of seal sleeve (39). 38A 36 10. If o-rings (38A) or support rings (38B) are damaged, replace with new parts. Examine plunger (36) for wear. 39A 39 41 42 43 45 11.

GP7132 AND GP7136 REPAIR INSTRUCTIONS CAUTION: Don't loosen the 3 plunger (36) before the valve casing has been removed otherwise the plunger (36) could hit against the spacer pipe (51F) when the pump is being turned. Seal life can be increased if the pretensioning allows for a little leakage. This assists lubrication and keeps the seals cool. It is therefore not necessary to replace seals before the leakage becomes too heavy and causes output and operating pressure to drop.
