Frequently Asked Questions
Q: What equipment uses the YL 516595602 hydraulic pump?
A: The YL 516595602 is a hydraulic pump for Yale electric lift trucks, pallet jacks, and reach trucks. It powers the mast lift and load handling functions. This pump is compatible with 24-volt or 80-volt electric motor drive systems depending on your equipment configuration. Confirm your vehicle model and hydraulic system type before ordering.
Q: What are the pump displacement and pressure specifications for the YL 516595602?
A: Displacement is typically measured in cubic centimeters per revolution (cc/rev) and varies by model version. Maximum system pressure rating is usually 210 to 280 bar depending on valve settings and equipment design. Check your equipment service manual for exact specifications and pressure relief settings.
Q: What failure symptoms indicate the YL 516595602 pump is failing?
A: Common failure signs include slow or no mast lift, reduced load capacity, jerky lifting motion, unusual noise or grinding from the pump, visible oil leaks from pump seals, or hot hydraulic fluid. If the mast will not lift, check fluid level and filter condition before assuming pump failure.
Q: How long does the YL 516595602 hydraulic pump typically last?
A: Under normal operating conditions with regular hydraulic fluid changes and filter maintenance, the YL 516595602 has a service life of 6 to 10 years. Lifespan is reduced by contaminated fluid, high ambient temperatures, or continuous heavy lifting. Replace if internal wear causes pressure loss or noise.
Q: What maintenance extends the life of the YL 516595602 pump?
A: Change hydraulic fluid according to manufacturer intervals, typically every 500 to 1000 operating hours. Replace filters regularly to prevent pump wear from contamination. Check all hydraulic connections for leaks monthly. Monitor fluid condition for discoloration or odor, which indicates overheating or oxidation.
