Frequently Asked Questions
Q: What is the YL 580015604 hydraulic breather designed for?
A: The YL 580015604 is an OEM hydraulic breather for Yale MPB040E (B827) and MPW045E (B802) electric pallet truck power unit hydraulic reservoirs. It provides atmospheric ventilation while filtering contaminants.
Q: What are the material and thread specifications for the YL 580015604?
A: The YL 580015604 is constructed from thermoplastic with 1/2 inch NPT male threads. It features nominal 40 micron filtration media (porous plastic disc) for contaminant removal.
Q: Which Yale electric pallet truck models accept the YL 580015604?
A: The YL 580015604 is compatible with Yale MPB040E (model designation B827) and MPW045E (model designation B802) electric pallet trucks. Confirm your model number before ordering.
Q: What is the filtration rating and function of the YL 580015604?
A: The YL 580015604 provides nominal 40 micron filtration. It removes particulates and moisture that enter the hydraulic reservoir during thermal cycling. This protects pump and actuator components from contamination-induced wear.
Q: Is the YL 580015604 a pressurized or atmospheric component?
A: The YL 580015604 is a non-pressurized atmospheric breather. It equalizes pressure between the hydraulic reservoir and ambient air as fluid level and temperature change during truck operation.
Q: How does a plugged hydraulic breather affect pallet truck performance?
A: A clogged breather restricts air exchange, causing vacuum formation in the reservoir. This can slow hydraulic actuator response, reduce lifting speed, or prevent proper pump operation. Regular visual inspection and cleaning of the porous filter disc maintains peak performance.
