Frequently Asked Questions
Q: What are the exact dimensions of the CR 20252-1 motor brush?
A: The CR 20252-1 measures 0.62 inch in thickness, 1.24 inch in width, and 1.34 inch in length. These dimensions are designed for precise fit in Crown electric lift truck traction motor and hydraulic motor assemblies. Verify measurements match your motor brush holder before ordering.
Q: Is the CR 20252-1 compatible with both traction and hydraulic motors?
A: Yes, the CR 20252-1 is manufactured for use in both Crown electric lift truck traction motor applications and hydraulic motor assemblies. It is fully cross-referenced to replace CR 020252-1 and CR 20252-001. Confirm your specific motor assembly type and bore dimensions before ordering.
Q: What material grade is the CR 20252-1 brush constructed from?
A: The CR 20252-1 is manufactured from high-purity electric motor grade carbon. This material provides superior commutator performance, reduced brush wear, and consistent electrical contact across varying load conditions. The composition is engineered specifically for continuous duty lift truck motor cycles.
Q: What parts does the CR 20252-1 supersede or cross-reference?
A: The CR 20252-1 supersedes CR 020252-1 and CR 20252-001. It is equivalent to OEM part numbers 020252-001 and 20252-1. If you are replacing an older brush assembly, any of these part numbers indicate the correct fitment.
Q: How do I know if the CR 20252-1 will fit my Crown lift truck motor?
A: Measure your motor brush holder bore dimensions and compare them to the CR 20252-1 specifications of 0.62 inch thickness, 1.24 inch width, and 1.34 inch length. Confirm your motor is a Crown traction or hydraulic motor assembly. Cross-reference your existing brush part number to 020252-1, 20252-001, or 20252-1 for compatibility verification.
Q: What is the expected lifespan of the CR 20252-1 motor brush?
A: High-purity electric motor grade carbon brushes typically last 1,200 to 2,500 operating hours in continuous duty lift truck applications, depending on commutator condition, brush holder wear, and actual load cycling. Regular inspection for brush length reduction and commutator arcing will help determine replacement timing.
