Continental Contitech 20043077 Timing Belt Xl 85T

Product Description

The CONTINENTAL CONTITECH 20043077 is an XL-section positive-drive timing belt designed for precision power transmission in light-duty mechanical and industrial drive applications. Constructed from nylon with a fiberglass cord reinforcement, this belt delivers consistent pitch accuracy and resistance to stretching under load. It carries the belt number 170XL, features 85 trapezoidal teeth, and has an internal length of 17.0 inches. Trapezoidal tooth geometry provides positive engagement with matching XL-profile sprockets, reducing slippage and maintaining accurate timing between drive components. This belt is a stock replacement or new-installation option suited for OEM-spec and aftermarket drive assemblies.

XL-series timing belts are widely used in light industrial machinery, HVAC blower assemblies, pump drives, conveyor systems, and equipment requiring synchronized shaft rotation. The 170XL designation places this belt in the standard XL pitch family, making it straightforward to source matching sprockets and tensioners. Technicians and equipment service professionals working on small-frame motor drives, fan assemblies, or precision machine components will find this belt a direct fit wherever an XL-section, 85-tooth timing belt is specified.

Key Features

• XL-section positive-drive belt with 85 trapezoidal teeth for accurate, slip-free power transmission
• Nylon construction provides durability and resistance to wear under normal drive loads
• Fiberglass cord reinforcement minimizes stretch and maintains consistent pitch length over service life
• Belt number 170XL with 17.0-inch internal length fits standard XL-profile sprocket systems
• Trapezoidal tooth profile ensures positive meshing with mating XL drive sprockets

Compatibility

Designed as a direct replacement or new-installation timing belt for drive systems specifying an XL-section, 85-tooth, 170XL-number belt with standard XL-pitch trapezoidal tooth profile.

Installation Notes

Installation should be performed by a qualified mechanical or HVAC technician. De-energize and lock out the drive system before removing the old belt or installing this belt. Do not pry or force the belt over sprocket flanges, as this can damage the fiberglass cord and reduce service life. Verify sprocket alignment and tension according to the equipment manufacturer's specifications before returning the drive to service.
