Product Description
Professional-grade motor brush spring set for electric lift truck drive motors. This 4-piece set contains high-carbon spring steel springs engineered to maintain optimal brush contact pressure and motor performance. Designed as a direct replacement for Prestolite-type motor assemblies commonly used in Crown, Toyota, Raymond, and Yale electric pallet jacks, reach trucks, and walkie movers. Proper maintenance of motor brush springs extends motor service life and ensures reliable power transmission under demanding warehouse and dock conditions.
Frequently Asked Questions
Q: What equipment does the PL MGP-185S spring set fit?
A: The PL MGP-185S is a 4-piece spring set designed for electric lift truck motor brush assemblies, compatible with Prestolite-type motor designs commonly found in Crown, Toyota, Raymond, and Yale electric pallet jacks and reach trucks. Verify your motor brush assembly configuration before ordering to ensure fitment.
Q: How many springs are included in this set?
A: The PL MGP-185S contains four (4) individual springs as a complete replacement set for one motor brush assembly.
Q: What material are these springs made from?
A: The PL MGP-185S springs are manufactured from high-carbon spring steel, engineered to maintain consistent tension and load-bearing capacity across repeated motor cycles in material handling applications.
Q: What is the typical lifespan of these motor brush springs?
A: Spring lifespan varies based on motor usage intensity and load cycle frequency. Under normal operation in moderate-duty applications, these springs typically perform for 1,000 to 2,000 operating hours before tension loss requires replacement. High-intensity or continuous-duty equipment may require replacement sooner.
Q: How do I know if these springs need replacement?
A: Symptoms of worn motor springs include reduced brush contact pressure (visible as arcing or sparking at the motor commutator), intermittent power loss during operation, or excessive brush wear. If your lift truck exhibits reduced power output or audible electrical noise from the motor, these springs may have lost tension and require replacement.
Q: Are these springs compatible with all Prestolite motors?
A: The PL MGP-185S is specifically engineered for standard Prestolite motor brush assemblies. While widely used in Crown, Toyota, Raymond, and Yale equipment, motor specifications vary by model year and configuration. Confirm compatibility with your equipment's motor specifications before purchasing.
