Frequently Asked Questions
Q: What is the 853943 washer designed for?
A: The 853943 is a load-bearing washer for wheel axle assemblies and suspension mounting bolts on sit-down forklifts and pallet jacks. It spreads fastener load across the mounting surface to prevent wheel hub cracking and axle bearing failure.
Q: What material does the 853943 use?
A: The 853943 is constructed from tempered steel with zinc plating for corrosion protection. The tempered hardness provides dimensional stability under the repetitive shock loads generated by wheel contact with floor surfaces.
Q: What equipment is the 853943 compatible with?
A: The 853943 fits Crown, Mitsubishi, Clark, and Hyster material handling equipment. It is suitable for both manual and electric forklifts. Verify your wheel hub diameter and fastener size match your equipment specifications before ordering.
Q: What is the expected service life of the 853943?
A: The 853943 typically lasts 3,000 to 6,000 service hours depending on load capacity utilization and floor surface conditions. High-frequency loading in narrow-aisle environments or outdoor concrete surfaces may reduce service life to 2,500 hours.
Q: When should the 853943 washer be replaced?
A: Replace the 853943 if wheel wobble develops, if the washer shows visible cracks or spalling, or if it no longer maintains flush contact with the wheel hub during axle inspection. Also replace if fasteners require retightening more frequently than normal, indicating washer yielding.
Q: Does the 853943 have any cross-reference part numbers?
A: Cross-reference your equipment manual for alternative part numbers in your warehouse system. The 853943 performs the same function as equivalent OEM load washers from Crown, Mitsubishi, and Clark. Verify dimensions and material specifications match before substituting.
