Hydraulic SystemXR620/621/842/1045/1245/1254/1267/1534/2050/30348-20 MAINTENANCE REQUIREMENTS FOR FAILED PUMPIf the hydraulic pump should fail, the hydraulic fluid will very likely be contaminated with metal particlesand other types of contaminants. In addition to replacing the pump, the following maintenance actionsshould be taken:• Drain the reservoir.• Clean or replace the hydraulic reservoir strainer.• Fill the reservoir with clean, filtered hydraulic fluid.• Replace the high-pressure filter.• Replace the return line filter.• Operate all hydraulic systems through ten cycles of operation.• If any subsystem fails or has degraded performance, the components of that system should beremoved from the forklift, disassembled, and thoroughly cleaned.• Remove the return line filter. Inspect the filter and hydraulic fluid for contamination.If the hydraulic fluid is still contaminated, perform the following maintenance actions:• Drain the reservoir.• Clean or replace the hydraulic reservoir strainer.• Fill the reservoir with clean, filtered hydraulic fluid.• Replace the high-pressure filter.• Replace the return line filter.• Operate all hydraulic systems through ten cycles of operation.• If any subsystem fails or has degraded performance, the components of that system should beremoved from the forklift, disassembled, and thoroughly cleaned.• Take a sample of the hydraulic fluid and have it analyzed. Perform additional maintenance perrecommendations provided in the hydraulic fluid analysis report.Service Manual Rev 01 – 05/10 8-47P/N 24933-000
