HTD Belt 24.567in Long 20mm Wide

The Jones Racing Products HTD Belt 24.567in Long 20mm Wide (Model 624-20 HD) is a high-performance drive belt engineered for marine auxiliary systems, inboard engine accessory drives, and bilge pump applications. This HTD synchronous belt delivers reliable power transmission where precise belt engagement and minimal slippage are critical to safe boat operation, whether on weekend fishing runs or extended offshore cruises.

At 24.567 inches in circumferential length with 20mm width and 8mm pitch, this belt is designed to coordinate seamlessly with marine accessory pulleys and drive systems requiring precise synchronization. The HTD (High Torque Drive) profile provides positive tooth engagement without creep, preventing slippage under load—a critical advantage when driving cooling water pumps, alternators, or vacuum systems on marine engines. The compact 0.17 lb weight and narrow 20mm profile allow for installation in space-constrained engine compartments typical of center console and express cruiser configurations.

This belt suits boaters who prioritize reliable accessory system performance and marine equipment maintenance. Replacing worn or slipping belts prevents cascade failures—a seized alternator belt leaves you without charging capability; a failed water pump belt risks engine overheating in open water. Jones Racing Products' HTD specification ensures that replacement belts meet OEM engagement standards. Verify fitment against your engine's accessory drive configuration before ordering, as belt length and pitch specifications are precise.

HTD belts have become the marine industry standard for applications requiring repeatable power transmission without maintenance adjustment. Unlike V-belts, HTD designs eliminate the need for tension monitoring and seasonal adjustments, offering set-and-forget reliability across temperature swings and extended idle periods typical of seasonal boating use.
