The Husqvarna 587174502 Capacitor is a genuine OEM component designed for HTC280, HTC510, HTC450, PG280, PG450, PG510, and PG510I floor grinders. As a direct factory replacement, this capacitor delivers the correct electrical specification required to keep your grinder's motor starting and running at full output. DHS Equipment supplies this part to help keep your equipment running at peak performance across the full range of compatible Husqvarna floor grinders.
Key Features
- Correct Capacitance Rating — manufactured to Husqvarna's OEM specification, ensuring the proper microfarad rating and voltage tolerance required for the motor circuit in these floor grinders
- Drop-In Electrical Replacement — matches the original connector and form factor, allowing this capacitor to install directly in place of the factory unit without modification
- Broad Grinder Compatibility — fits HTC280, HTC450, HTC510, PG280, PG450, PG510, and PG510I floor grinders, covering a wide range of Husqvarna planetary grinder models
- Restores Motor Start Performance — a worn or failed capacitor can cause hard starts, reduced torque, motor overheating, or complete failure to start; replacing it with this OEM unit restores normal motor function
- Electrical Safety Compliance — using a genuine OEM capacitor with the correct voltage and capacitance rating protects the motor windings and associated electrical components from damage caused by an out-of-spec unit
A capacitor in a floor grinder motor circuit stores and releases electrical energy to generate the phase shift needed to start and run the motor efficiently. It provides the initial torque burst that brings the motor up to operating speed and, in run capacitors, continues to improve motor efficiency during operation. When a capacitor degrades or fails, the motor may struggle to start, draw excess current, overheat, or shut down under load — all of which interrupt grinding operations and can cause secondary damage to the motor windings if left unaddressed.
