CR 113989

Frequently Asked Questions

Q: What does the CR 113989 contactor tip kit contain?
A: The CR 113989 is an OEM Crown contractor tip kit that contains high-conductivity contact elements designed to restore electrical continuity in contactor assemblies. These contact tips are engineered for the specific contactor configuration used in Crown electric lift trucks and ensure reliable high-current switching.

Q: Which Crown lift truck models are compatible with the CR 113989?
A: The CR 113989 is intended for compatibility with specified Crown electric lift truck models. Contact us with your lift truck model number and serial number to confirm fitment and to identify any recommended superseding part numbers if your truck uses a newer contactor assembly design.

Q: What material are the contact elements in the CR 113989?
A: The CR 113989 uses high-conductivity contact elements optimized for minimal electrical resistance during contactor switching. High-conductivity contacts reduce heat generation in the contactor coil, improve motor response, and extend the operating life of the contactor assembly in Crown lift trucks.

Q: How often should the CR 113989 contactor tip kit be replaced?
A: Contactor tip replacement frequency depends on lift truck usage intensity and electrical load. With normal material handling duty, contactor tips typically remain serviceable for 3 to 5 years. Heavy-duty or continuous operation may require more frequent replacement. Replace the CR 113989 when you observe reduced motor acceleration or contactor chatter.

Q: What symptoms indicate the CR 113989 needs replacement?
A: Replace the CR 113989 if the lift truck experiences slow or hesitant acceleration, intermittent power loss, audible clicking or chattering from the contactor, or visible pitting and discoloration on the old contact tips. These signs indicate that contact wear is increasing electrical resistance in the motor control circuit.
