Q: What is the material composition of the TO 00590-04748-71 brushes?
A: The brushes are constructed from carbon-graphite material, which provides conductivity and controlled wear rates. Carbon-graphite is standard for industrial electric motor brushes in material handling equipment.
Q: Why does the TO 00590-04748-71 come as a set of 4?
A: The set of four brushes matches the standard brush configuration in Toyota traction and hydraulic pump motors. Most motor commutators require replacement of all four brushes simultaneously to ensure balanced electrical contact and prevent motor damage.
Q: What is the maintenance interval for brush replacement?
A: The TO 00590-04748-71 is classified for scheduled preventive maintenance. Brush life depends on motor run time and load cycles. Typical replacement occurs every 1,500 to 3,000 operating hours. Inspect for wear and scoring on the commutator as indicators of brush degradation.
Q: What symptoms indicate the TO 00590-04748-71 brushes need replacement?
A: Signs include reduced motor performance, increased noise or grinding, visible sparking at the brush contacts, blackened or damaged commutator surface, or arcing during operation. These symptoms indicate brush wear and potential motor damage if not addressed.
