Key Features
- Correct Electrical Specification — Manufactured to Husqvarna's exact capacitance and voltage rating for the PG400, ensuring the motor receives the precise charge it needs at startup and during operation.
- Genuine OEM Part — Sourced directly from Husqvarna, this capacitor matches the original component in every respect — no substitutions, no compromises on fit or function.
- Direct Drop-In Replacement — Engineered to connect to the existing wiring and mounting points on the PG400 floor grinder, allowing for a straightforward swap during servicing.
- Fits the PG400 Floor Grinder — Verified for the PG400; cross-reference 587174503 against your machine's parts diagram to confirm compatibility before installation.
- Restored Motor Performance — A failed or degraded capacitor causes sluggish motor starts, overheating, or complete failure to run; replacing it with this OEM part restores normal grinder operation immediately.
A capacitor stores and releases electrical energy to help the motor start and maintain a steady run cycle. In a floor grinder like the PG400, the capacitor provides the initial voltage boost the motor needs to reach operating speed, and in many designs it also supports smooth running under load. When a capacitor degrades or fails, the motor may struggle to start, run erratically, draw excess current, or shut down under load — all of which interrupt grinding work and can cause broader motor damage if left unaddressed.
