Repair Repair Disassembly 1. Relieve pressure. See system manual for pressure relief instructions. NOTICE Recommended Hydraulic Oil 2. Use two people to lift and clamp the cylinder (1) in a vise. Use Graco-approved Hydraulic Oil, Part No. 169236 (5 gal) or 207428 (1 gal)) or a premium, ISO grade 46 petroleum-based hydraulic oil containing rust and oxidation inhibitors and anti-wear agents. NOTICE To prevent damage to sealing surfaces, do not clamp any sealing surfaces in the vise.
Repair Assembly Residual hydraulic oil in the cylinder can spray out of ports during removal of the piston assembly. NOTE: Be careful not to damage piston rod assembly (9). 7. Place a cloth over the hydraulic ports (P). Use a rubber mallet to tap piston rod assembly (9) out of cylinder (1). NOTE: Be careful not to damage piston rod assembly (9). 1. Clamp piston rod (9) flats or hex in a vise to prevent damage to the piston rod. 2.
Repair 5. Lubricate inside of cylinder (1) with hydraulic oil to allow easy installation of piston assembly. Continue to next step if the cylinder hasn’t been flushed and there is residual hydraulic oil. 9. Install second seal housing (2) on cylinder (1). Torque to 150-160 ft-lbs (203-216 N•m). NOTE: Use a rubber mallet to gently tap seal housing while turning by hand to start threading the seal housing into cylinder. 1 1 2 lubricate with hydraulic oil r_258640_3A0020A_6h 6.
