Frequently Asked Questions
Q: What is included in the HY 1334247 brush set?
A: The HY 1334247 is a 4-piece factory-matched brush set for Hyster electric lift truck motors. Each set contains carbon-graphite composite brushes with copper shunt and integral spring, delivered as a complete matched assembly for direct replacement.
Q: Why is the carbon-graphite material used in the HY 1334247 brushes?
A: Carbon-graphite composite provides excellent electrical conductivity, low friction against the commutator, and self-lubricating properties. This material reduces brush and commutator wear, extends service life, and maintains consistent electrical contact during continuous 24VDC motor operation.
Q: Why must the HY 1334247 brushes be replaced as a matched set?
A: The 4-piece set is factory-matched to ensure uniform brush pressure and electrical contact across all commutator segments. Mixing old and new brushes creates uneven contact, causing commutator pitting, brush wear imbalance, and reduced motor efficiency in Hyster electric lift trucks.
Q: Which Hyster motors use the HY 1334247 brush set?
A: The HY 1334247 is engineered for Hyster 24VDC continuous duty electric lift truck motors. It works with motors that use the HY 1334244 brush holder and HY 1334245 brush spring. Verify your equipment motor specifications before ordering to ensure correct fitment.
Q: Is the HY 1334247 compatible with other lift truck brands?
A: The HY 1334247 is an OEM Hyster component. Cross-application with Crown, Toyota, Raymond, Yale, or other manufacturers requires matching brush bore diameter, copper shunt design, and commutator segment spacing. Do not use as a substitute without dimensional verification.
