Frequently Asked Questions
Q: Which Crown reach trucks use the CR 87391 hub?
A: The CR 87391 hub is designed for Crown RS Series Reach Trucks. This hub serves as a connecting component between the axle assembly and the load wheel or steer wheel. The RS Series includes multiple production years and variants, so verify your specific reach truck model and serial number before ordering.
Q: What are the dimensional specifications for the CR 87391 hub?
A: The CR 87391 hub is a special order item with specific bore, width, and mounting hole configurations matched to RS Series Reach Truck axle assemblies. Exact dimensions depend on whether this hub is for front steer wheels or rear load wheels. Provide your truck model number and axle location for precise fitment confirmation.
Q: What material is the CR 87391 hub manufactured from?
A: The CR 87391 hub is typically cast iron or ductile iron construction, selected for strength and durability under the dynamic loads of a reach truck wheel assembly. This material resists wear and maintains dimensional stability under repeated start, stop, and directional load cycles common in warehouse environments.
Q: How long does the CR 87391 hub typically last in service?
A: A properly functioning CR 87391 hub can last the operational life of the reach truck if wheel bearings are maintained and the truck is not subjected to repeated overloads or impact damage. Replace the hub if it shows cracking, missing mounting surfaces, or severe wear at the bore. Hub failure typically occurs due to bearing degradation or axle damage rather than hub material fatigue.
Q: Is the CR 87391 hub compatible with other Crown reach truck models besides the RS Series?
A: The CR 87391 hub is specific to the RS Series Reach Truck. Do not assume compatibility with other Crown reach truck lines such as the WR Series or RC Series. Cross-model fitment is not guaranteed without verified bore diameter, mounting hole count, and axle shaft specifications. Contact us with your exact truck model to identify the correct hub.
