Frequently Asked Questions
Q: What are the brush dimensions on the RA 570-604/512?
A: The RA 570-604/512 brushes are nominally 1.13 x 0.50 x 0.31 inch. These dimensions are critical for fitment in Raymond motor brush housings; verify against your equipment before purchase.
Q: What material are the RA 570-604/512 brushes made from?
A: The RA 570-604/512 brushes are constructed from carbon-graphite composite material with copper pigtail terminals. Carbon-graphite provides low electrical resistance and controlled wear for reliable motor commutation.
Q: What is the continuous and peak current rating for the RA 570-604/512?
A: The RA 570-604/512 brushes are rated for continuous current of 38 amperes and peak current of 62 amperes. Operating beyond these ratings will shorten brush life and damage the motor.
Q: Which Raymond 7400 reach truck models use the RA 570-604/512?
A: The RA 570-604/512 fits Raymond 7400 Reach Truck Drive Lift Pump and Motor Assembly DC models. Confirm your reach truck model and serial range match the 7400 specification before ordering.
Q: Does the RA 570-604/512 come pre-assembled or loose?
A: The RA 570-604/512 consists of four individual brushes with spring-loaded mounting. The brushes are spring-mounted for direct fit into Raymond motor brush holders without additional fasteners.
Q: How long do RA 570-604/512 brushes typically last in operation?
A: Brush life depends on truck usage, load cycles, and motor operating temperature. Raymond DC motors typically operate 10,000 to 15,000 hours with original equipment. Monitor for arcing, noise, or reduced lift speed as indicators that brush replacement is due.
