Frequently Asked Questions
Q: What does a Woodruff key do in electric lift trucks?
A: A Woodruff key is a mechanical fastener that prevents relative motion between a shaft and hub by transmitting torque. The CR 042051-001 is used in Crown equipment drivetrain and motor shaft assemblies.
Q: Which Crown models require the CR 042051-001 Woodruff key?
A: The CR 042051-001 is a Crown OEM part for electric lift trucks. Confirm your equipment model number and shaft specifications match this key before ordering.
Q: Can I use an equivalent Woodruff key instead of CR 042051-001?
A: Only if the replacement key has identical dimensions, material grade, and keyway specifications. Using an undersized or oversized key can cause shaft slippage and equipment failure. Verify specifications before substitution.
Q: What signs indicate a Woodruff key needs replacement?
A: Symptoms include shaft wobbling relative to the hub, visible rust or corrosion on the key surface, or equipment loss of power transmission. Replacement is necessary to restore proper drivetrain function.
