Frequently Asked Questions
Q: What are the specifications of the 77084-040-A assembly?
A: It uses 95A durometer Durarun polyurethane compound and includes integrated shoulder bearing assembly for complete load wheel replacement on Crown pallet jacks and electric lift trucks.
Q: Is the 77084-040-A compatible with Crown PE 4000 equipment?
A: The 77084-040-A is engineered for Crown electric pallet truck and lift truck load wheel applications. Cross-reference your equipment nameplate to confirm compatibility with PE 4000 or similar Crown models. The integrated bearing design makes this a complete replacement assembly, so verify that your equipment uses a shouldered bearing configuration.
Q: What polyurethane compound is used and what hardness rating does it have?
A: The 77084-040-A uses Durarun 95A polyurethane, rated at 95A Shore A hardness. This compound is designed for standard warehouse and material handling environments with typical concrete or composite flooring. It is not formulated for cold storage or wet floor applications.
Q: What cross-reference part numbers are equivalent to this assembly?
A: The 77084-040-A is equivalent to CR077084-040, CR77084040, 77084040, CR077084, and 077084. If you see any of these numbers on your equipment, the 77084-040-A is the direct replacement. Always verify the bearing configuration matches before ordering.
Q: What is the expected service life of the shoulder bearings?
A: The integrated shoulder bearing design is engineered for extended service life under continuous lift truck operation. Bearing lifespan depends on load, floor conditions, and maintenance practices. Regular inspection for noise, resistance, or play in wheel rotation indicates bearing wear. Replace the assembly when bearing noise becomes audible or wheel spin becomes sluggish.
