BREATHER AND DIP STICK
Frequently Asked Questions
Q: What is the purpose of the BJ 504578 breather and dip stick assembly?
A: The BJ 504578 breather and dip stick assembly serves dual functions: the breather allows hydraulic fluid to ventilate while preventing contamination and moisture from entering the hydraulic tank, and the dip stick enables fluid level monitoring and maintenance checks.
Q: Which lift truck models use the BJ 504578 breather and dip stick?
A: The BJ 504578 is compatible with electric lift trucks and pallet jacks from major manufacturers including Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Verify your equipment model references the BJ 504578 SKU.
Q: Why is the breather function important on the BJ 504578?
A: The breather prevents moisture and airborne contaminants from entering the hydraulic system. Without proper ventilation, water accumulates in the tank, causing rust, seal degradation, and fluid breakdown. A blocked or failed breather reduces equipment reliability and accelerates fluid oxidation.
Q: How often should the BJ 504578 dip stick be used for fluid checks?
A: Perform hydraulic fluid level checks using the dip stick weekly or before heavy-use shifts. Keep the fluid level within the marked range on the dip stick. Low fluid levels cause pump cavitation and system noise; overfilled tanks can damage seals.
Q: What maintenance does the BJ 504578 breather element require?
A: Inspect the breather element for clogs, dirt buildup, and damage at regular intervals. If the element becomes blocked, airflow is restricted and pressure can build inside the tank. Replace the breather element if performance degrades or visible contamination is present.
