Frequently Asked Questions
Q: What does the YL 220051435 brush set do in a Yale electric lift truck?
A: The YL 220051435 brush set is a carbon-graphite assembly for brushed DC motors on Yale electric lift trucks. It transfers electrical current from the stationary holder to the rotating motor commutator, enabling continuous duty operation across 24VDC to 48VDC systems.
Q: Is the YL 220051435 compatible with non-Yale lift truck brands?
A: The YL 220051435 is designed specifically for Yale ERP series and compatible Yale electric lift truck motor assemblies. This part does not cross-reference to Crown, Toyota, Raymond, or other OEM brands. Do not attempt to substitute on different manufacturer equipment.
Q: What are the cross-reference part numbers for the YL 220051435?
A: The YL 220051435 supersedes prior revision 220051435R, replaces E4558, and is equivalent to E-4558. Interchange numbers include E4558 and 220051435R. Always verify that cross-reference parts are original OEM stock and not used or reconditioned inventory.
Q: How long does the YL 220051435 brush set last before replacement?
A: Carbon-graphite brush sets typically require replacement every 1000 to 2000 operating hours, depending on motor load, duty cycle intensity, and ambient conditions. Monitor brush wear during maintenance intervals. Worn brushes reduce electrical contact quality and motor efficiency.
Q: What material properties does the YL 220051435 carbon-graphite construction provide?
A: The carbon-graphite composition provides excellent electrical conductivity, self-lubricating properties, and commutator compatibility. ASTM-compliant materials ensure stable contact resistance and reduced arcing under continuous duty on both 24VDC and 48VDC truck systems.
