Trane a35 V-belt Drive 37.2 in Od 36.3 in Pitch

Product Description

The TRANE a35 is a standard A-section V-belt designed for drive applications in HVAC air-handling systems. With an outside diameter of 37.2 inches and a pitch length of 36.3 inches, this belt delivers reliable power transmission between motor and blower pulleys. The A-section profile fits standard A-series sheaves and is built to handle the continuous-duty demands of residential and light-commercial air-handling equipment. Licensed HVAC technicians and experienced service professionals typically handle replacement as part of scheduled preventive maintenance or unplanned belt-failure service calls.

This V-belt is suited for belt-driven blower assemblies found in central air systems, furnaces, and air handlers where an A-section drive belt is specified. It is appropriate for installations requiring a 37.2-inch outside diameter belt with a 36.3-inch pitch. Technicians should confirm both the section designation and pitch length against the existing belt or equipment documentation before installing.

Key Features

• A-section V-belt profile fits standard A-series sheaves and pulleys
• 37.2-inch outside diameter with 36.3-inch pitch length for precise drive fitment
• Engineered for continuous-duty blower drive service in HVAC applications

Compatibility

Designed as an OEM-style replacement A-section V-belt for belt-driven blower assemblies in HVAC air-handling equipment requiring a 37.2-inch OD, 36.3-inch pitch drive belt.

Installation Notes

Belt replacement is typically performed by a licensed HVAC technician. Disconnect and lock out electrical power to the unit before removing the belt guard or accessing the drive assembly. Never force a belt over a sheave with a pry tool, as this can damage belt fibers and reduce service life. After installation, verify proper belt tension and pulley alignment per the equipment manufacturer's service documentation before returning the unit to operation.
