International Comfort Products 74335 A31 V-belt 33.2 Inches

Product Description

The INTERNATIONAL COMFORT PRODUCTS 74335 is an A31 standard V-belt rated at 33.2 inches in outside circumference. This belt transmits rotational power between the motor sheave and blower pulley in forced-air HVAC systems. The A-section profile fits standard A-series sheaves and is a direct OEM-style replacement for units requiring a 31-inch inside circumference belt. HVAC technicians install this belt during blower motor service, belt replacement on scheduled maintenance visits, or when diagnosing reduced airflow caused by a worn or slipping drive belt. The 0.65-pound weight makes handling straightforward during rooftop or air handler service calls.

This belt is suited for residential and light commercial air handling units, package units, and split-system air handlers that use belt-driven blower assemblies. It is commonly installed in units where the original equipment specified an A31 cross-section belt. Technicians should verify the sheave diameter and center-to-center distance before ordering to confirm correct belt length for the application.

Key Features

• A-section V-belt profile fits standard A-series sheaves and pulleys
• 33.2-inch outside circumference for precise fitment in belt-driven blower assemblies
• Lightweight at 0.65 pounds, simplifying handling in confined air handler cabinets
• OEM-style replacement for INTERNATIONAL COMFORT PRODUCTS equipment specifying an A31 belt
• Standard cross-section allows cross-reference to Browning and other A31-equivalent belts

Compatibility

Designed as an OEM-style replacement V-belt for INTERNATIONAL COMFORT PRODUCTS equipment requiring an A31 belt designation. Verify sheave size and center distance before installation to confirm proper fit.

Installation Notes

A licensed HVAC technician or qualified mechanic should perform belt replacement. Disconnect and lock out electrical power to the air handler or package unit before opening the blower compartment. Never pry a belt onto a sheave under full tension; loosen the motor mounting bolts to reduce center-to-center distance, seat the belt, then adjust tension per manufacturer guidelines before re-tightening. Check belt tension and alignment after the first few hours of operation.
