Frequently Asked Questions
Q: What does the PR 307634-000 brush kit include?
A: The PR 307634-000 is a brush kit that includes two carbon brushes. This set is the complete replacement assembly for Prime Mover electric lift truck motor applications where both brushes should be replaced as a pair.
Q: Which Prime Mover lift truck motors use the PR 307634-000 brushes?
A: The PR 307634-000 is an OEM brush assembly designed for Prime Mover electric motor applications. Verify your specific truck model and motor type before ordering to confirm compatibility.
Q: Why should both brushes be replaced together as a set?
A: Carbon brushes wear at similar rates when operating together. Replacing only one brush creates an imbalance in electrical contact pressure and wear, leading to uneven brush wear, reduced motor efficiency, and premature failure of the new brush. Always replace both brushes as the PR 307634-000 kit is designed.
Q: What symptoms indicate the PR 307634-000 brushes need replacement?
A: Signs of worn brushes include reduced motor power, slow or inconsistent truck movement, sparking at the motor commutator, and audible arcing noise. If you notice any of these symptoms, inspect brush wear. Replace with the PR 307634-000 kit when brushes are worn to approximately one-quarter inch length or show uneven wear.
Q: How long do carbon brushes typically last in a Prime Mover lift truck?
A: Carbon brush lifespan depends on motor duty cycle, load conditions, and operating hours. Light-duty trucks may run 1000 to 2000 hours between brush replacements, while heavy-duty applications may require brushes every 500 to 1500 hours. Regular maintenance and prompt brush replacement extends overall motor life.
Q: Are there cross-reference part numbers for the PR 307634-000 brush kit?
A: The PR 307634-000 is also referenced as 307634-000 or 307634000 in some parts systems. Use any of these numbers to locate the same two-brush kit for Prime Mover motors.
