Loosen plugs (56) and take out complete valve assemblies (51) with a slide hammer. Use a bent piece of wire to remove the o-rings (52). 2. To dismantle the valves, carefully tap the valve plate (51B) with a bolt until the valve seat (51A) is pushed out of the spacer pipe (51D). 3. Check the sealing surfaces and replace all worn parts. Check the o-rings. 4. When reinstalling the valve assemblies, particular care must be taken so that the o-rings (52) sit properly in their fittings in the valve casing. 5. Tighten the plugs (56) to 160 ft.-lbs. (220 NM). To Check Seals and Plunger Pipe 6. Loosen nuts (49A) and remove the valve casing (50). 7. Separate the plunger connection (36) from the crosshead assembly (25) by means of two open-end wrenches (size 22mm and 27mm). 8. Pull seal sleeves (40) out of their fittings in the crankcase (1). 9. Take the seal case (41) out of the seal sleeve (40). 10. Examine plunger parts (36-39) and seals (44 and 45). 11. Check o-rings (41A through 41D) and replace worn parts. 12. When replacing plunger pipe (37), tighten tension screw (38) to 30 ft.-lbs (40 NM). 13. Grease seals with Silicone before reinstalling. IMPORTANT: Do not loosen the three plunger screws (36) before the valve casing (50) has been removed; otherwise, the tension screw (38) could hit against the spacer pipe (51D) when the pump is being turned. 14. The seal unit (43, 44, 44A) is pre-tensioned by a spring (42). Seal life can be increased if the loading allows for a little leakage. This assists lubrication and keeps the seals cool. It is therefore not necessary to replace the seals before the leakage becomes too heavy and causes output and operating pressure to drop. 15. When reassembling, tighten plunger screw (36) to 33 ft.-lbs. (45 NM). Mounting Valve Casing 16. Check o-rings on seal case (41). 17. Clean surfaces of seal sleeves in crankcase (1) and sealing surfaces of valve casing (50). 18. Push valve casing (50) carefully onto o-rings (41A and 41B) of seal case and centering studs (49C). 19. Tighten nuts (49A) to 103 ft.-lbs. (140 NM). To Dismantle Gear 20. As described above, take out the plunger and seal sleeves. Drain the oil. 21. After removing the circlip ring (33B), use a screw driver to lever out the seal retainer (33). 22. Check the seals (32, 32A and 33A) and surfaces of the crosshead (25). 23. Remove the crankcase cover (4) and make sure that the o-ring (5) looks good. 24. Loosen the inner hexagon screws on the connecting rods (24). IMPORTANT: Connecting rods are marked for identification. Do not twist connecting rod halves. Connecting rod halves are to be reinstalled in the same position and orientation onto the crankshaft (22). 25. Push the connecting rod halves as far into the crosshead guide as possible. 26. Take out the bearing cover (14) to one side and push out the crankshaft (22) taking particular care that the connecting rod halves don’t bend IMPORTANT: Seal (32A) must always be installed so that the seal lip on the inside diameter faces the oil. Possible axial float of the seal adaptor (33) is to be compensated for with shims (33C). 27. Reassemble in reverse order 28. Regulate axial play of the crankshaft clearance to minimum of 0.1mm, maximum of 0.15mm by means of fitting disc (20A). The crankshaft should turn easily and with little clearance. 29. Tighten the inner hexagon screws to 30 ft-lbs. (40 NM). IMPORTANT: The connecting rods have to be able to slightly moved sidewise at the stroke journals. 6 REPAIR INSTRUCTION - GP6132 PUMP SYSTEM MALFUNCTIONS MALFUNCTION CAUSE REMEDY The Pressure and/ or the Delivery Drops Worn packing seals Broken valve springs Belt slippage Worn or Damaged nozzle Fouled discharge valve Worn or Plugged relief valve on pump Cavitations Replace packing seals Replace springs Tighten or Replace belt Replace nozzle Clean valve assembly Clean, Reset, and Replace worn parts Check suction lines on inlet Unloader of pump for restrictions Check for proper operation Water in Crankcase High Humidity Worn Seals Reduce oil change intervals Replace seals Noisy Operating Worn bearings Replace bearings, Refill crankcase oil with recommended lubricant Cavitation Check inlet lines for restrictions and/or proper sizing Rough/Pulsating Operation with Pressure Drop Worn packing Inlet restriction ...
