Frequently Asked Questions
Q: What does the WW PM-29P O-ring seal and what are its specifications?
A: The WW PM-29P is a hydraulic seal O-ring for Dayton model 3KR84 manual pallet jack hydraulic units. It prevents hydraulic fluid leakage from critical pressure points within the unit, maintaining system performance and preventing oil loss.
Q: Which Dayton pallet jack models require the WW PM-29P O-ring?
A: The WW PM-29P is compatible with Dayton model 3KR84 manual pallet jacks. Always verify the O-ring bore diameter and groove dimensions match your specific hydraulic unit before ordering. Using an incorrectly sized seal results in leaks and system failure.
Q: How often should the WW PM-29P O-ring be replaced as preventive maintenance?
A: Hydraulic O-rings like the WW PM-29P do not have a fixed replacement interval but should be inspected annually for signs of degradation, hardening, or swelling. Replace the seal immediately if you detect leaks, or at 3 to 5 year intervals if the jack is in regular heavy-duty service or exposed to temperature extremes or contaminated hydraulic fluid.
Q: What hydraulic fluid types are compatible with the WW PM-29P O-ring?
A: The WW PM-29P is designed for use with standard mineral-based hydraulic fluids. Always use the hydraulic fluid type specified in your Dayton pallet jack manual. Some synthetic fluids or high-viscosity fluids may cause the seal to swell or degrade prematurely. Verify fluid compatibility before service to avoid seal damage.
