13 SERVICE NOTES: Use a clean lubricant (compatible with the working fluid) on all pump components during assembly. Thoroughly clean the reservoir, suction lines, suction strainer, drain lines, etc. before re-installing the pump. Most premature pump failures occur when contaminants from a previous failure have not been completely removed from the system, or cause for previous failure is still present (i.e. water in oil, filter bypassing, etc.). Always fill the case with clean fluid before starting a new or serviced pump (fill as high as inlet port will allow on a PAVC style pump). For flooded suction, purge air from suction lines by cracking the inlet fitting or vent plug on pump body. This should prevent an airlock condition and allow for faster priming. Starting the pump slowly by jogging (or turning over engine without allowing it to start) will help the pump prime and makes it easier to determine when priming has occurred. Check for proper shaft rotation if there is a possibility it may have changed during a system rebuild. Start pump with an open circuit whenever possible. Reduce the compensator to its minimum setting during start-up. Cycle the pump on and off stroke while increasing the compensator to its required setting. This will assist in break-in of new components and help purge air from the case. BASIC TROUBLESHOOTING: Pump Won t Prime Note: Pump should prime within 30 seconds. If it does not, STOP! Check for proper drive rotation. Make sure pump shaft is turning (i.e. key at coupling hubs is engaged). Make sure reservoir is full. Check for major sources of a suction leak (vent plug open, shaft seal missing (PAVC), flange not tight, pinched o-ring at flange or pump housing, etc.). Can t Build Any Pressure Make sure pump is primed. Check alignment, especially on PAVC pumps without 9 option. Make sure system is not an open circuit. (A pump produces flow, not pressure. It can only limit pressure when the system requirement is higher than the pump compensator setting.) Can Only Build A Few Hundred PSI Compensator is backed all the way out. Remote/load sense line is vented. Control orifice is plugged. Pressure control dart is lodged open. Torque control plug missing (PAVC). Wrong compensator spool (PVP). Pump Won t Compensate Differential spring over-compressed (i.e. spring guide dislocated). Drain line blocked (PAVC). Pressure control stem vent hole is plugged. Spool travel hindered. Control orifice missing (PAVC). Saturation orifice missing in load sense circuit. Hydraulics Greeneville, TN

Incorrect installation or assembly of these parts could cause the pump or pumps being repaired to fail in subsequent use, or to operate incorrectly. The following precautions should be followed:. All parts should be cleaned and then lightly coated with mineral oil, or another lubricating fluid compatible with the system fluid being used, prior to assembly.. The pump should be disassembled, repaired, and reassembled in a clean environment. 3. Use proper tools to disassemble and reassemble the pump. 4. If you are uncertain as to how to install these parts, you should obtain assistance either from a Parker Hannifin distributor, or from the Fluidpower Pump Division. 9

47 Bulletin PM 60--M/USA Service Notes & Basic Troubleshooting Parker Pumps Parts & Service Model PVP6 **** Service Notes: l l l l l l Use a clean lubricant (compatible with the working fluid) on all pump components during assembly. Most premature pump failures occur when contaminants from a previous failure have not been removed from the system, or cause for previous failure is still present (i.e. water in oil, filter bypassing, etc.) Thoroughly clean the reservoir, suction lines, suction strainer, drain lines, etc. before re-installing the pump. Always fill the pump case with clean fluid before starting a new or serviced pump for flooded suction, purge air from suction lines by cracking the inlet fitting or vent plug on pump. This should prevent an airlock condition and allow for faster priming. Starting the pump slowly by jogging (or turning over engine without allowing it to start) will help the pump prime and make it easier to determine when priming has occurred. Start pump with an open circuit whenever possible. Reduce the compensator to it's minimum setting during start-up. Cycle the pump on and off stroke while increasing the compensator to its required setting. This will assist in break-in of new components and help purge air from the case. Basic Troubleshooting: Pump Will Not Prime Pump should prime within 30 seconds. If it does not, STOP. Check for proper drive rotation. Make sure pump shaft is turning (i.e. key at coupling hubs is engaged). Make sure reservoir is full. Check for major sources of a suction leak (vent plug open, shaft seal missing (PAVC), flange not tight, pinched O-Ring at flange or pump housing. Cannot Build Any Pressure Make sure pump is primed. Check alignment, especially on PAVC pumps without "9" option. Make sure systems is not an open circuit. A pump produces flow, not pressure. It can only limit pressure when the system requirement is higher than the pump compensator setting. Can Only Build A Few Hundred PSI Compensator is backed all the way out. The remote or load sense line is vented. Control orifice or spool is plugged. Incorrect compensator spool (PVP). Pressure control dart is lodged open. Torque control plug is missing (PAVC). Pump Will Not Compensate Differential spring over-compressed (i.e. spring guide dislocated). Control drain line blocked (PAVC). Pressure control stem vent hole is plugged. Control spool travel is hindered. Control orifice is missing (PAVC). Saturation orifice is missing in load sense circuit. Greeneville, TN USA
