Continental Contitech 20043138 Timing Belt 270L L Section

Product Description

The CONTINENTAL CONTITECH 20043138 is an L-section positive-drive timing belt designed for precise power transmission in mechanical drive systems. Constructed from nylon with a fiberglass tension cord, it delivers consistent pitch accuracy and resistance to stretch under cyclic loading. The belt runs 27.0 inches in internal length with 72 trapezoidal teeth spaced on the standard L-series pitch of 3/8 inch. It is installed by mechanical technicians and maintenance professionals on OEM and replacement drive applications requiring exact timing and synchronization.

This belt is suited for light- to medium-duty synchronous drive applications found in HVAC equipment, industrial machinery, pumps, and other powered mechanical assemblies that use L-series timing pulleys. The trapezoidal tooth profile mates with standard L-section timing pulleys for reliable, slip-free power transfer. It is sold as a single belt per package, making it appropriate for one-for-one replacement service work or new drive assembly builds.

Key Features

• L-section positive-drive belt with 72 trapezoidal teeth for accurate synchronization
• Nylon construction provides durability and resistance to wear across repeated flex cycles
• Fiberglass tension cord minimizes stretch and maintains consistent pitch length under load
• 27.0-inch internal length with a 270L belt designation for straightforward replacement cross-reference
• Trapezoidal tooth profile mates with standard L-series timing pulleys

Compatibility

Designed as an OEM-style replacement timing belt for mechanical drive systems using L-section timing pulleys with a 270L belt designation.

Installation Notes

Installation is performed by qualified mechanical technicians or maintenance personnel. Always de-energize and lock out the drive system before removing the old belt or installing the replacement. Verify pulley alignment and center distance before tensioning the new belt. Do not pry or force the belt over pulley flanges, as this can damage the tension cord and reduce service life.
