Husqvarna 501831503 Clutch Drum 2 Pack Chainsaw

Product Description

The HUSQVARNA 501831503 is an OEM clutch drum sold in a 2-pack, designed for use in Husqvarna chainsaws. The clutch drum connects the centrifugal clutch assembly to the drive sprocket and chain, transmitting power from the engine to the cutting chain during operation. When the engine reaches the engagement RPM, the clutch shoes expand outward and contact the drum interior, driving the chain. This is a direct-fit OEM replacement component, making it suitable for technicians and service shops performing routine maintenance or restoring a saw to factory-specified function.

Clutch drums are a wear item in chainsaw service. Over time, the drum interior develops grooves from clutch shoe contact, reducing engagement efficiency and accelerating wear on adjacent components. Replacing the drum restores proper power transfer and protects the clutch shoes and sprocket from compounded wear. This 2-pack quantity suits service shops that maintain fleets of saws or technicians who prefer to keep a spare on hand for back-to-back repairs.

Key Features

• OEM Husqvarna part — factory fit and material specification
• Sold as a 2-pack, reducing per-unit cost for service shops

Compatibility

Designed as an OEM-style replacement clutch drum for compatible Husqvarna chainsaw models. Verify fitment against the specific model and serial number using Husqvarna parts documentation before installation.

Installation Notes

Clutch drum replacement is typically performed by a qualified small-engine technician or chainsaw service professional. Before beginning, disconnect the spark plug wire and allow the saw to cool completely. A clutch removal tool is required to hold the crankshaft stationary while loosening the clutch assembly — use of improvised tools risks crankshaft or bearing damage. Refer to the model-specific service manual for the correct removal and torque sequence.
