Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to Husqvarna's exact tolerances, this spacer plate maintains the correct motor offset critical to consistent grinding head engagement and drivetrain alignment.
- Direct Drop-In Replacement — Engineered to match the original mounting pattern and plate thickness, this component installs directly into the motor assembly without modification.
- Broad PG400 Series Compatibility — A single part that fits the PG400, PG400II, PG400III, and PG400IV floor grinders, making it straightforward to cross-reference part number 585083301 against your machine's parts diagram.
- Restored Motor Stability — A worn or damaged spacer plate can allow motor movement and misalignment, leading to vibration, uneven grinding, and premature wear on surrounding components. This replacement restores secure, stable motor positioning.

The Motor Spacer Plate sits between the motor and its mounting structure within the PG400 series floor grinder's drivetrain assembly. Its role is to establish and maintain the correct spatial relationship between the motor and the components it drives, ensuring proper load transfer and preventing unwanted movement during operation. When this plate becomes worn, cracked, or dimensionally compromised, motor misalignment can follow — introducing vibration, accelerating wear on bearings and seals, and reducing the quality and consistency of the grinder's output surface.
