Makita 181-224-040 Rim Sprocket .325 Inch Pitch

Product Description

The MAKITA 181-224-040 is a rim sprocket with a .325 inch pitch, designed for use in Makita chain saws and compatible cutting equipment. Rim sprockets drive the saw chain around the guide bar, transferring power from the engine or motor to the cutting chain. This component is a direct replacement part suited for installation by qualified technicians or experienced power equipment service professionals. The .325 inch pitch designation identifies the chain spacing this sprocket is built to match, making correct pitch selection critical before ordering.

This rim sprocket is intended for use in chain saw applications where a .325 inch pitch chain is specified. It is typically found in light- to medium-duty cutting equipment used in landscaping, arborist work, and general outdoor power equipment service. Replacement is commonly performed during routine drivetrain maintenance or when wear, cracking, or damaged sprocket teeth are identified during inspection.

Key Features

• Rim-style sprocket design for standard chain saw drivetrain applications
• .325 inch pitch matches compatible saw chain and guide bar combinations
• OEM Makita replacement part, direct-fit for applicable models
• Rim construction allows sprocket replacement independent of the drum when applicable

Compatibility

Designed as an OEM-style replacement rim sprocket for Makita chain saw models specifying a .325 inch pitch chain. Verify pitch, gauge, and drive link count against your existing chain and bar before installation.

Installation Notes

Rim sprocket replacement should be performed by a qualified small engine or power equipment technician. Disconnect the spark plug wire or power source before beginning any drivetrain service. Remove the clutch cover and clutch assembly per manufacturer service documentation before accessing the sprocket. Inspect the clutch drum and needle bearing for wear at the same time, as these components wear together and are typically replaced as a set.
