Frequently Asked Questions
Q: What is the DA BK100 hydraulic seal kit used for?
A: The DA BK100 is a complete hydraulic seal kit engineered for the pump and cylinder assemblies in Dayton model 4YX97 manual pallet jacks. It replaces worn seals that prevent hydraulic fluid leakage during lift and lower operations.
Q: What materials does the DA BK100 seal kit contain?
A: The DA BK100 consists of Nitrile rubber seals, carbon seal faces, and ceramic backing elements. Nitrile provides resistance to mineral hydraulic oils and temperature variations typical in warehouse material handling equipment.
Q: Which Dayton pallet jack models are compatible with the DA BK100 seal kit?
A: The DA BK100 is designed for Dayton model 4YX97 manual pallet jacks with a 5/8 inch pump shaft. It is compatible with B Series hydraulic assemblies. Verify your equipment model and shaft diameter before ordering.
Q: What are cross reference part numbers for the DA BK100?
A: The DA BK100 is equivalent to seal kit numbers WW 97-100 and 5NP21. If you have access to equipment documentation with those part numbers, the DA BK100 will provide identical performance and compatibility.
Q: How do I know the DA BK100 seal kit needs replacement?
A: Replace the DA BK100 if you observe hydraulic fluid leaking from the pump or cylinder, reduced lifting pressure, difficulty achieving full lift height, or fluid dripping under the pallet jack when parked. These are signs that seals have degraded.
Q: What is the expected service life of the DA BK100 seal kit?
A: Under normal warehouse operation with regular maintenance and proper hydraulic fluid levels, the DA BK100 seal kit typically provides 4 to 7 years of service. Lifespan varies based on frequency of use, ambient temperature, and hydraulic fluid contamination.
