Frequently Asked Questions
Q: What does the CR 089718 carbon brush set contain and what are the brush dimensions?
A: The CR 089718 is an OEM set of four high-grade carbon brushes for Crown electric lift truck motors. Each brush measures 1.3 inches in length, 1.24 inches in width, and 0.628 inches in thickness. These brushes fit direct into motor brush slots without modification.
Q: Which Crown motors use the CR 089718 carbon brushes?
A: The CR 089718 is verified authentic OEM and optimized for Crown electric lift truck traction motors and hydraulic pump motors. Confirm brush slot dimensions match your existing brushes before ordering. Verify the motor manufacturer is Crown and the brush configuration is direct slot mounting.
Q: What is the material composition and grade of the CR 089718 brushes?
A: The CR 089718 brushes are constructed from high-grade carbon material engineered for Crown motor electrical specifications. Carbon composition affects conductivity and wear rate. These OEM brushes are optimized for Crown motor commutators and have no superseded or cross-reference replacements.
Q: How do I know when motor brushes need replacement?
A: Replace brushes when the motor shows reduced torque, slow response, arcing inside the motor, visible sparking at the brush holder, or complete motor failure. Worn brushes reduce electrical contact with the commutator, causing voltage drop and loss of power.
Q: How long do carbon brushes typically last?
A: Carbon brushes for Crown electric lift truck motors last 3 to 5 years or 1000 to 1500 operating hours depending on duty cycle and motor load. Heavy duty or continuous operation wears brushes faster. Replace all four brushes together to maintain balanced motor performance.
Q: Are there any cross-reference or equivalent part numbers for the CR 089718?
A: The CR 089718 is verified authentic OEM with no superseded or cross-reference replacements. Use only this exact Crown part number to ensure correct fit and motor performance. Substituting non-OEM carbon brushes risks electrical incompatibility and motor damage.
