b.Wash metal parts in an approved solvent and dry with low pressure, filtered, compressed air.c.Check the wearing surfaces of pressure plates (7, 12) and ring (10) for scoring and excessive wear. Removelight scores by lapping. Replace scored or worn parts.d.Inspect the vanes (9) for burrs, wear and excessive play in the rotor slots. Replace damaged vanes with a vaneand spring kit. Replace the rotor (8) if slots are worn.e.Rotate the bearing (22) on shaft (21) while applying pressure to check for wear, looseness, roughness and pittedor cracked races.f.Inspect the seal and bushing mating surfaces on the shaft (21) for scoring or wear. Replace the shaft if markscannot be removed by light polishing.g.Be sure that any paint or burrs raised on the body (27) and cover (2) are removed before assembly.4-14.1.4 Assembly. (Figure 4-36).NOTECoat all parts with clean hydraulic fluid to facilitate assembly and provide initial lubrication.Use small amounts of petroleum jelly to hold o-rings in place during assembly. Soak the shaftwiper (26) in oil before assembly.a.Install the wiper (26) in body (27). Grease the shaft seal (25) and press it into the body using seal driver (seefigure 4-35). The spring on seal must be toward the bearing (22). Place the washer (24) in the body against theseal.b.Support the bearing (22) inner race and press in the shaft (21). Install snap ring (23).c.Lightly tap the shaft and bearing (21, 22) assembly into the body (27) with a plastic hammer. Install the lockring(20) to secure shaft. Be sure the lockring is properly installed.NOTEIf an assembled cartridge kit is being installed, proceed to step k.d.With the rotor (8) lying on a clean, flat surface, slide the vanes and springs (9, 11) into the rotor slots. Lift thevanes slightly to insure the springs are positioned in the spring recesses of the rotor.CAUTIONBe certain the springs remain seated as the vanes are compressed.e.Using a piston ring compressor, compress the vanes (9) in the slots of the rotor (8).4-154
