Continental Contitech 20043123 Timing Belt 480L L Section

Product Description

The CONTINENTAL CONTITECH 20043123 is an L-series positive-drive timing belt designed for precision power transmission in mechanical drive systems. It features 128 trapezoidal teeth and a 480L belt number, corresponding to a 48.0-inch internal length. The belt body is constructed from nylon with a fiberglass tensile cord, providing dimensional stability under cyclic load and resistance to stretch over service life. This belt is installed by mechanical and industrial service technicians in applications requiring accurate speed ratios and synchronous shaft drive.

The 20043123 is suited for L-section timing belt drive systems where trapezoidal tooth profile and fiberglass cord construction are specified. L-series belts are commonly found in light industrial machinery, HVAC blower assemblies, conveyor drives, and equipment requiring positive, non-slip power transmission. The 480L designation follows the standard L-series belt numbering convention, making cross-referencing against OEM drive specifications straightforward.

Key Features

• L-section trapezoidal tooth profile for positive, slip-free drive engagement
• 128 teeth with 480L belt number and 48.0-inch internal length
• Nylon belt material for durability and wear resistance
• Fiberglass tensile cord for low stretch and dimensional stability
• L Series Positive Drive configuration for accurate speed and timing synchronization

Compatibility

Designed as an OEM-style replacement for L-section positive-drive timing belt applications requiring a 480L belt with 128 trapezoidal teeth and a 48.0-inch internal length.

Installation Notes

Timing belt replacement is typically performed by mechanical or HVAC service technicians. Before servicing, de-energize the drive system and lock out the power source per LOTO procedures. Verify pulley alignment and check pulley groove condition before installing the new belt. Do not force the belt over pulley flanges or use tools that could cut or kink the cord body.
