Product Details

Gates PowerBand Green Stripe belts are engineered for problematic, heavy-duty, high-vibration accessory drive systems that require matched belt sets. The joined construction keeps the strands aligned so the belt rides more consistently in the pulley grooves, which supports smoother power transfer across the drive system. Part number 2/9670PB is also referenced by cross numbers such as 2/17671TT and 2B17670 for the same application.

Common Issues This Belt Can Address

• Belt flutter in high-vibration accessory drive systems
• Uneven loading across multiple V-belts
• Tracking instability in pulley grooves
• Noise caused by inconsistent belt alignment
• Wear associated with matched-belt drive setups

Installation Notes

Verify pulley groove width, belt section, and effective length before installation. Inspect the accessory drive pulleys for wear, contamination, or misalignment, since joined V-belts depend on proper groove engagement. Confirm the replacement matches the original belt profile and routing for the vehicle application.

Compatible With Ford F-150 and Chevrolet Silverado accessory drive belt applications where the specified HC50 joined V-belt is required. Use part number 2/9670PB to confirm the correct replacement during service.
