Continental Contitech 20042489 Cogged V-belt 3VX 33.5 in

Product Description

The CONTINENTAL CONTITECH 20042489 is a cogged V-belt in the 3VX section, also known by belt number 3VX335, with a 33.5-inch outside length. Constructed from fiber-reinforced Wingprene rubber, this belt delivers reliable power transmission in demanding drive applications. The cogged profile reduces bending resistance and improves heat dissipation compared to standard wrapped belts. Its oil-resistant construction makes it suitable for environments where fluid exposure is a service concern. HVAC technicians, mechanical contractors, and industrial maintenance professionals install this belt type in fan, blower, and motor drive assemblies.

The 3VX335 is designed for use in HY-T Wedge Matchmaker cogged drive systems. Typical applications include residential and commercial HVAC blower drives, refrigeration condenser fan drives, and general-purpose belt drive assemblies where a 3VX section cogged belt is specified. The cogged design allows this belt to run on smaller-diameter sheaves without excessive flex fatigue, making it a common choice in compact drive configurations found in rooftop units, air handlers, and fan coil equipment.

Key Features

• 3VX section cogged profile reduces flex heat and improves efficiency over standard wrapped belts
• Fiber-reinforced Wingprene rubber construction provides durability under continuous load
• Oil-resistant material resists degradation in environments with incidental fluid exposure
• 33.5-inch outside length matches OEM drive specifications for 3VX335 applications
• HY-T Wedge Matchmaker cogged style supports matched-set drive configurations

Compatibility

Designed as an OEM-style replacement for drive systems specifying a 3VX section cogged V-belt with a 33.5-inch outside length, belt number 3VX335.

Installation Notes

Belt replacement should be performed by a qualified HVAC technician or mechanical contractor. De-energize and lock out the equipment before removing the belt guard or accessing the drive assembly. Never pry a belt onto a sheave using a screwdriver or similar tool, as this can damage belt cords and shorten service life. Verify sheave alignment and condition before installing the new belt, and check belt tension per the drive manufacturer's specifications after installation.
