Continental Contitech 20043105 Timing Belt 135L 36T

Product Description

The CONTINENTAL CONTITECH 20043105 is an L-section timing belt designed for positive-drive power transmission applications. Built with a nylon construction and a fiberglass cord reinforcement, this belt delivers consistent pitch accuracy and resistance to stretching under load. It features 36 trapezoidal teeth and a 135L belt designation, corresponding to a 13.5-inch internal length and a 135.00 mm pitch length. Licensed trades and industrial maintenance technicians install this belt in equipment where synchronous motion control is required, such as conveyor drives, HVAC blower assemblies, and light industrial machinery.

This belt fits standard L-series positive-drive pulley systems. The trapezoidal tooth profile mates with matching L-section sprockets and pulleys. It is appropriate for both OEM replacement and new installation in residential and light commercial equipment where an L-series synchronous belt is specified. The 135L designation is a widely used industry-standard size that can be cross-referenced across multiple pulley and drive system manufacturers.

Key Features

• L-section belt with trapezoidal tooth profile for positive, no-slip drive engagement
• 36 teeth for precise synchronous motion indexing
• Fiberglass cord construction minimizes stretch and maintains pitch accuracy over time
• Nylon material provides durability and resistance to wear in drive applications
• 135L industry-standard designation for straightforward cross-referencing and replacement
• 13.5-inch internal length fits standard L-series sprocket configurations

Compatibility

Designed as an OEM-style replacement for L-series positive-drive belt applications using the 135L belt size with matching L-section pulleys and sprockets.

Installation Notes

Power down all equipment and lock out the drive system before removing the old belt or installing a new one, following LOTO procedures. Verify pulley alignment and center distance before seating the belt to avoid premature tooth wear. Do not force the belt over sprocket flanges with tools that can damage the tooth profile or cord. A qualified technician or equipment maintenance professional should perform this installation in accordance with the equipment manufacturer's service documentation.
