Service Parts Guide Summary
This document is a Parker Hannifin Service Parts Guide for the PAVC Series Variable Volume Piston Pump, Model PAVC 65, effective February 1996. The guide provides detailed technical specifications and component information for hydraulic pump maintenance and repair. The document includes comprehensive exploded views, assembly diagrams, and section drawings with labeled parts, torque specifications ranging from 10 to 125 foot-pounds, and critical installation depths for needle bearings. Multiple configuration options are detailed, including inlet port variations (rear port or top port), control options (OMIT, A, C, H, M, ME, S, SE, AM, CM, HM), differential variations (non-adjustable and adjustable), maximum volume stop variations, and dual shaft bearing configurations.
The parts catalog identifies 77 distinct components with part numbers and quantities required for pump assembly and maintenance. Key component categories include shafts, housing units, seals, springs, pistons, barrels, and various plugs and fittings. The guide specifies shaft seal options (items 1 and 65), both standard and optional needle bearing configurations, trunnion housing assemblies, and pressure compensation and servo control assemblies. A critical caution section emphasizes proper cleaning, assembly procedures, use of compatible lubricants, and the importance of clean work environments during pump disassembly and reassembly. The document directs users to consult Parker Hannifin distributors or the Fluidpower Pump Division for uncertain installation procedures.

These service parts are intended for use in hydraulic pumps.
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:
1. 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.
2. 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.
