Continental Contitech 20042765 Cogged V-belt 4L 37in

Product Description

The CONTINENTAL CONTITECH 20042765 is a fractional horsepower cogged V-belt designed for light-duty power transmission in HVAC, agricultural, and general industrial drive applications. Built from high traction rubber, this 4L-section belt measures 37 inches outside length and 36 inches internal length. The cogged profile reduces bending resistance, which improves flexibility around smaller sheaves and helps lower operating temperatures. It carries an abrasion-resistant and ozone-resistant compound, making it suitable for environments where belt degradation from UV exposure or particulate contact is a concern. HVAC technicians, equipment mechanics, and facilities maintenance professionals install this style of belt on fan drives, blowers, and light power-transmission assemblies.

The 4L-section cogged V-belt is commonly installed on residential and light commercial HVAC systems including condenser fan drives, furnace blower assemblies, and evaporative cooler drives. It is also widely used on small compressors, pumps, and general-purpose power transmission setups that rely on fractional horsepower sheave-and-belt drives. The belt number 4L370 is the standard industry designation for this size and section, allowing cross-reference with compatible sheaves and drives specified for the 4L series. This belt is sold and installed individually as a single-unit replacement.

Key Features

• Cogged design reduces flex resistance and heat buildup on small-diameter sheaves
• High traction rubber construction provides reliable grip under variable load conditions
• Abrasion-resistant compound extends service life in dusty or gritty environments
• Ozone-resistant formulation resists surface cracking in outdoor or UV-exposed installations
• Wide operating temperature range from -40 degrees F to 284 degrees F (140 degrees C)
• Industry-standard 4L370 belt number for straightforward cross-reference and replacement

Compatibility

Designed as an OEM-style replacement for fractional horsepower drive systems requiring a 4L-section V-belt with a 37-inch outside length and 36-inch internal length. Cross-references by belt number 4L370.

Installation Notes

Belt replacement is typically performed by HVAC technicians or equipment mechanics. Always disconnect and lock out power to the drive system before removing or installing a belt. Loosen the motor mounting fasteners to relieve tension before removing the old belt, then seat the new belt in the sheave grooves before adjusting tension to the drive manufacturer's specification. Avoid prying the belt over sheave flanges, as this can damage the cord structure and reduce service life.
