Frequently Asked Questions
Q: What are the specifications for the CR 087885 motor brush set?
A: The CR 087885 is a carbon composition motor brush for Crown electric lift trucks. Each set contains four brushes with the following dimensions: 1.24 inches width by 0.628 inches thickness by 1.3 inches length. These brushes are designed for precise current transfer and wear resistance.
Q: Why is the CR 087885 brush set supplied as four pieces?
A: Motor and hydraulic assemblies in Crown electric lift trucks typically use four brushes positioned around the commutator or rotating component. The set of four ensures you have matched brushes for balanced current transfer, optimal performance, and even wear.
Q: How often should the CR 087885 brushes be replaced?
A: Brush lifespan depends on motor duty cycle, current load, and operating hours. Carbon composition brushes typically require replacement after 1500 to 3000 operating hours. Inspect regularly for wear debris, reduced brush length, or motor performance loss as indicators of replacement need.
Q: What are the symptoms of worn CR 087885 motor brushes?
A: Signs of worn brushes include reduced motor power, excessive sparking, grinding noise, or inconsistent equipment movement. You may also see copper debris or brush dust in the motor housing. Replace all four brushes as a set to maintain balanced performance.
Q: Can I use the CR 087885 as a direct replacement brush for other equipment?
A: The CR 087885 is designed specifically for Crown electric lift truck motor and hydraulic applications. Brush replacement requires exact dimensional and material match. Verify dimensions, carbon grade, and current rating before using as a replacement on other equipment models.
Q: What is the difference between carbon composition and other brush materials?
A: Carbon composition brushes like the CR 087885 provide good conductivity, wear resistance, and commutation performance for industrial lift truck motors. They handle variable loads effectively and are standard for Crown electric lift truck applications.
