Frequently Asked Questions
Q: What is the 5059665-78 transmission filter and which lift trucks does it fit?
A: The 5059665-78 is a transmission filter for electric lift trucks. It removes contaminants from hydraulic fluid to protect transmission components and extend system life. Verify your lift truck model and transmission type to confirm compatibility before ordering.
Q: What are the filter specifications for the 5059665-78?
A: Filter specifications include micron rating, flow capacity, and connection port size. The 5059665-78 is designed for specific transmission systems; verify your equipment pressure rating and fluid flow requirements match the filter specifications to ensure proper operation.
Q: What materials make up the 5059665-78 filter?
A: The filter typically features a synthetic or fiberglass media designed to capture particles while maintaining adequate flow rates. The housing is usually aluminum or steel. The media rating determines what size contaminants get blocked without restricting fluid circulation.
Q: How often should the 5059665-78 transmission filter be replaced?
A: Follow your lift truck manufacturers service schedule, typically every 500 to 1000 operating hours depending on operating conditions and fluid cleanliness. Change intervals shorten in dusty or contaminated environments. Monitor pressure differential indicators; replace when restrictions develop.
Q: What happens if the 5059665-78 filter becomes clogged?
A: A clogged filter restricts fluid flow, causing reduced transmission pressure, sluggish shifting, or transmission overheating. Bypass valves may open, allowing unfiltered fluid through and causing accelerated wear. Replace immediately if pressure warnings activate or performance degrades.
Q: Is the 5059665-78 compatible with all transmission fluid types?
A: The filter is designed for hydraulic fluids matching your lift truck manufacturers specification. Use the correct fluid viscosity and type; incorrect fluids degrade filter media and reduce protection. Confirm your fluid specification before ordering replacement filters.
