Frequently Asked Questions
Q: What is the CR 089719 brush plate used for?
A: The CR 089719 is a brush plate component for electric reach trucks and pallet jacks. It is part of the traction motor electrical circuit and manages current distribution and brush contact during motor operation. This part is critical to maintaining proper motor function and electrical performance.
Q: Which Crown electric lift trucks use the CR 089719 brush plate?
A: The CR 089719 fits various Crown electric reach truck models and configurations. Cross-reference your equipment model number and serial range with Crown documentation to confirm this part is correct for your specific unit. Contact technical support with your equipment details for precise compatibility verification.
Q: What are the symptoms of a failing brush plate on a Crown electric lift truck?
A: Common failure indicators include loss of drive motor power, erratic acceleration or deceleration, sparking visible through motor inspection ports, burnt smell from the motor compartment, or inconsistent load lift performance. If these symptoms occur, the brush plate may require inspection or replacement.
Q: Is the CR 089719 a wear item that requires periodic replacement?
A: Yes, the brush plate is a consumable component subject to electrical and mechanical wear. The carbon brushes on the plate gradually wear down with continuous motor use. Operating hours, motor duty cycle, and electrical load all affect replacement intervals. Inspect annually and replace when brush thickness is less than 1/8 inch remaining.
Q: What material is the CR 089719 brush plate made from?
A: The CR 089719 brush plate is constructed from reinforced phenolic or composite material with embedded carbon brushes designed to maintain electrical contact with the motor commutator. The composite backing provides dimensional stability and electrical insulation properties required for traction motor circuits.
Q: Can the CR 089719 brush plate be cleaned and reused or must it be replaced?
A: Once carbon brushes are worn to replacement thickness, the brush plate assembly must be replaced as a unit. Cleaning or sanding worn brushes is not recommended, as it compromises brush pressure, contact geometry, and electrical performance. Replace with a new CR 089719 when wear limits are reached.
