Accessory Drive Belt Overview

The Gates 6433BR accessory drive belt is an OE Exact replacement built for lawn and garden equipment applications. It uses a narrow section molded notch V-belt design with EPDM construction and aramid cord reinforcement for consistent fit and dependable belt tracking.

Compatible With Polaris Pro XD Full-Size Diesel and Polaris PRO XD 2000D / 4000D applications listed below, this belt is identified by part number 6433BR and matches the original belt composition and construction for the specified equipment.

Key Features

  • Aramid cord material for added tensile strength.
  • 3VX cross section with a 45-degree angle profile.

Detailed Description

Gates Special Belt line products are engineered to match the composition, construction, and fit of original belts used on common lawn and garden equipment. The 6433BR follows that approach with a molded notch profile, EPDM belt material, and aramid reinforcement to support proper drive performance in accessory applications. If you are replacing a worn accessory drive belt on Polaris Pro XD Full-Size Diesel or Polaris PRO XD 2000D / 4000D equipment, this part number provides a direct OE-style service option.

This part cross-references MAHLE 5704 for the same application.

What It Helps Address

  • Belt cracking or glazing from age and heat exposure.
  • Loss of proper belt tension or tracking.
  • Squealing or slipping in the accessory drive system.
  • Wear-related belt stretch that affects drive performance.

Installation Notes and Tips

Verify the belt profile, outside circumference, and application before installation. Confirm the equipment uses the listed alternator application and compare the old belt to Gates 6433BR for size and construction match. Proper pulley alignment and tension setup are important for service life.

Quality Assurance

Gates Special Belt products are built to OEM-quality standards for lawn and garden equipment and are designed to match original belt construction and fit.
