Genuine Husqvarna Clutch Assembly - 537 11 05-03
The Genuine Husqvarna 537110503 Clutch Assembly is the heart of your saw's drive system. This centrifugal clutch is precision-engineered to engage at the correct RPM, ensuring smooth power transfer from the engine to the chain while preventing engine stalling at idle.
Smooth Power Engagement
This OEM clutch assembly features factory-calibrated springs and high-friction shoes designed specifically for Husqvarna's mid-range professional and rancher saws. Replacing a worn clutch restores cutting torque and eliminates the "creeping chain" issue caused by weak or broken clutch springs.

🛠️ Mechanic's Tip:
This is a left-hand thread (reverse thread) part. To remove the old clutch, you must turn it clockwise. We highly recommend using a piston stop tool and a proper clutch removal wrench to avoid damaging the crankshaft. Inspect your needle bearing and clutch drum for wear while the clutch is removed.
