Key Features
- Genuine OEM Drive Geometry — machined to Husqvarna's exact pulley diameter and groove profile, ensuring the belt seats and tracks correctly under continuous grinding loads
- Complete Assembly — supplied as a fully assembled center pulley unit, so the component drops into the existing mounting position without additional sub-assembly work
- Designed for the HTC650 Floor Grinder — engineered specifically for the HTC650 drive train, with fitment verified by Husqvarna's own part number 593477901
- Restored Drive Transmission — a correctly functioning center pulley maintains consistent belt tension and torque transfer to the grinding heads, preserving surface finish quality and grinding efficiency
- Durable Construction — built to handle the sustained rotational stress and vibration typical of production floor grinding, maintaining pulley integrity over extended service cycles
The center pulley is a core component of the floor grinder's belt-drive system, transferring power from the motor to the grinding head assemblies. It acts as the central routing point for the drive belt, and its alignment and condition directly affect how evenly torque is distributed across the machine. When the pulley wears, cracks, or becomes misaligned, the drive belt can slip, track unevenly, or fail prematurely — leading to uneven grinding performance and increased stress on surrounding drive components. Replacing a worn center pulley with a genuine OEM unit restores proper belt engagement and keeps the grinding system operating as designed.
