Frequently Asked Questions
Q: What is the WW PM-8P and where does it fit in a Dayton pallet jack?
A: The WW PM-8P is a hydraulic O-ring seal for Dayton model 3KR84 manual pallet jacks. It functions as a primary seal in the hydraulic cylinder or pump assembly, preventing fluid leakage during lift and lower cycles.
Q: What material is the WW PM-8P O-ring made from?
A: The WW PM-8P is manufactured from NBR nitrile rubber, a standard elastomer for hydraulic applications. Nitrile rubber provides good resistance to petroleum-based hydraulic fluids and maintains sealing capability across typical operating temperatures.
Q: How do I know if the WW PM-8P O-ring needs replacement?
A: Replace the WW PM-8P if you observe hydraulic fluid leakage at the cylinder or pump, loss of lifting pressure, or slow or unresponsive lift operation. O-ring degradation occurs over time and with exposure to hydraulic fluids and temperature changes.
Q: What is the typical lifespan of the WW PM-8P O-ring?
A: O-ring lifespan depends on usage frequency, hydraulic fluid condition, storage conditions, and temperature exposure. Regular maintenance and fluid checks extend seal life. Replace when performance degradation or leakage occurs.
Q: Is there a cross-reference part number for the WW PM-8P?
A: No official cross-reference or supersedes part numbers are published for the WW PM-8P. Order using the OEM part number WW PM-8P to ensure you receive the correct seal for your Dayton hydraulic unit.
