Husqvarna 640200036 Rim Sprocket 3/8 Pitch 7 Tooth

Product Description

The HUSQVARNA 640200036 is a rim sprocket designed for chainsaw drive systems. It transfers power from the clutch drum to the saw chain, controlling chain speed and tension during cutting. The sprocket features a 3/8-inch pitch and 7-tooth configuration, which must match the pitch of the saw chain in use. Installation and replacement are typically performed by outdoor power equipment technicians or experienced operators during routine drivetrain maintenance.

This rim sprocket is suited for chainsaw applications where the 3/8-inch pitch chain standard is specified. Rim-style sprockets are common in professional and semi-professional saw configurations, allowing the rim to be replaced independently of the drum body. This reduces maintenance cost and extends the service life of the overall clutch drum assembly.

Key Features

• 3/8-inch pitch matches standard 3/8-inch saw chain
• 7-tooth rim configuration for chain drive engagement
• Rim-style design allows rim replacement without replacing the full clutch drum
• OEM HUSQVARNA part for reliable fitment and durability

Compatibility

Designed as an OEM-style replacement rim sprocket for HUSQVARNA chainsaws specifying a 3/8-inch pitch, 7-tooth drive sprocket. Verify clutch drum compatibility and chain pitch before installation.

Installation Notes

Rim sprocket replacement is performed by qualified outdoor power equipment technicians. Disconnect the spark plug wire and allow all moving parts to come to a complete stop before beginning any drivetrain service. A clutch removal tool appropriate for the saw model is typically required to access and seat the sprocket correctly. Inspect the clutch drum bearing and chain at the same time, as uneven wear on any one component accelerates wear on the others.
