Frequently Asked Questions
Q: What equipment does the HY 3002679 brush set fit?
A: The HY 3002679 is a brush set designed for Hyster electric lift trucks. Confirm your truck model and serial range against product documentation before ordering.
Q: How do brush sets differ between motor types in electric lift trucks?
A: Brush sets vary by motor voltage, armature speed rating, and terminal configuration. A 12V motor brush set does not fit a 24V motor and vice versa. Verify voltage and frame size against your equipment nameplate.
Q: What is the cost of premature brush set failure due to contamination?
A: Dirty or damaged commutators cause rapid brush wear and require both brush and commutator replacement, doubling repair costs. A contaminated commutator scores the brush surface, accelerating failure to weeks instead of months.
Q: Do brush sets require matching replacement or can I replace individual brushes?
A: Brush sets should be replaced as a matched pair or set to maintain equal pressure and wear characteristics on the commutator. Replacing only one brush or worn brushes creates uneven contact and causes rapid re-failure.
Q: What causes brush chatter and how is it different from normal brush wear?
A: Brush chatter is vibration caused by worn brushes losing contact with the commutator or a damaged commutator surface. It differs from normal wear: chatter produces noise and sparking, while normal wear is silent. Chatter indicates commutator damage requiring machine shop restoration.
