Description
Overview:
This Genuine Honda Clutch Assembly (part no. 22000-ZM3-003) is a centrifugal clutch unit for Honda handheld brushcutters and small engine tools. Built from hardened steel with bonded friction linings and coil springs, it transfers engine power smoothly to the drive when revs increase, then disengages at idle to prevent head creep. It is designed for the Honda UMK425E brushcutter and engines in the GX25 family, giving reliable engagement and consistent cutting performance. Replacing a worn clutch restores bite, reduces slip, and helps protect the engine and gearcase from unnecessary stress. Suitable for professional use and home users who need dependable starting and clean pick-up under load in grass, brush, and light clearing work.
Key Features:
- Genuine Honda part for assured fit and function on compatible models
- Durable steel construction with friction linings for long service life
- Smooth, predictable engagement for better control and less head creep at idle
- Helps reduce slippage, heat build-up, and premature wear in the drive line
- Maintains efficient power transfer from engine to cutting attachment
- Consistent performance under varying loads common in brushcutting tasks
- Straightforward replacement with basic tools and standard workshop practice
- Supports safe operation by disengaging the drive when the engine returns to idle
- Built to OEM tolerances to match Honda crankshaft and drum interfaces
- Suitable for regular maintenance schedules to keep machines working reliably
Typical Applications:
Restoring drive engagement on Honda brushcutters where the head stalls, slips, or creeps at idle. Ideal after heavy use, glazing, overheating, or contamination of clutch linings. Used during engine overhauls, scheduled maintenance, or when symptoms include high revs with poor cutting action or vibration at take-up.
