Frequently Asked Questions
Q: What is the 00591-35188-81 brush holder assembly and what does it do?
A: The 00591-35188-81 is a brush holder assembly for electric lift truck dc traction motors. It maintains brush contact with the commutator, delivering current to motor windings. This assembly contains high-conductivity copper alloy contacts and glass-reinforced insulation for durability in continuous duty motor service.
Q: Which equipment models and part numbers does this brush holder cross-reference?
A: The 00591-35188-81 cross-references to Toyota part numbers yt220051425, yt509015804, and yt511274800. It supersedes ty00591-42287-81 and is equivalent to references pl50-525, ra570-240-119, and ra570-249-213. It also relates to part number 107090. This assembly is compatible with Toyota electric pallet jacks and lift trucks rated for up to 4-ampere continuous duty in dc traction circuits.
Q: What material properties and electrical specifications does this brush holder have?
A: The assembly features high-conductivity copper alloy contacts that provide low resistance and reliable power transfer. Glass-reinforced insulation resists electrical breakdown and mechanical wear. These materials are engineered for dc traction motor systems in standard material handling environments.
Q: How long does a brush holder assembly typically last?
A: Brush holder lifespan depends on motor duty cycle, environmental conditions, and maintenance. In normal continuous duty applications, these assemblies last 3-5 years or longer with proper brush maintenance. Wet or corrosive environments, heavy duty cycles, or poor brush condition accelerates wear. Monitor brush wear and commutator condition periodically to extend assembly life.
Q: What are the signs that a brush holder assembly needs replacement?
A: Symptoms include loss of motor power, erratic motor operation, visible arcing at the commutator, burnt or discolored insulation on the assembly, or loose brush contact. If brush wear has exceeded limits or insulation is damaged, replacement is necessary. Verify the exact failure mode with your motor controller technician before ordering.
Q: What makes and models is this brush holder compatible with?
A: This brush holder assembly is compatible with Toyota electric lift trucks and pallet jacks. It is designed for use in dc traction motor systems rated for up to 4-ampere continuous duty.
Q: How do I know if this is the right replacement part for my equipment?
A: Check your equipment's model number and consult the cross-reference list provided. This assembly is compatible with Toyota electric lift trucks and pallet jacks, and it supersedes ty00591-42287-81. Ensure the part number matches your equipment's specifications.
