3288724 Diesel Fan Belt Ribbed for 6BT Engine – V-Ribbed Serpentine Belt

Product Details

Product Overview

This high-quality ribbed fan belt, identified by part number 3288724, is a critical component for the cooling system of the renowned Cummins 6BT diesel engine. Designed to drive the engine’s fan and often the alternator, this belt ensures optimal airflow and temperature regulation, preventing engine overheating and maintaining peak operational efficiency. The “ribbed” or “V-ribbed” design provides superior grip and power transmission compared to traditional V-belts, reducing slippage and extending service life.

Manufactured to meet or exceed OEM specifications, this 3288724 belt is a direct replacement for the original equipment found on a wide range of industrial and automotive applications powered by the 6BT series. As a critical wear item, maintaining this belt in good condition is essential for the reliability of your diesel engine, especially in demanding environments like construction, agriculture, and material handling. This product is sourced from a reliable supply chain in Chongqing, China, ensuring a balance of quality and competitive pricing for global B2B buyers.

Key Features & Benefits

• Precision Fitment: Engineered specifically for the Cummins 6BT engine, ensuring correct tension and alignment for the fan and accessory drive system.
• Ribbed Design for Superior Grip: The multi-ribbed profile provides a larger contact surface area, reducing belt slippage under high load and ensuring efficient power transfer to the cooling fan.
• Durable EPDM Rubber Construction: Made from high-grade EPDM (Ethylene Propylene Diene Monomer) rubber, offering excellent resistance to heat, ozone, and cracking, which extends the belt’s operational lifespan.
• Reduced Maintenance: This durable belt requires less frequent adjustment and replacement compared to standard belts, reducing downtime and maintenance costs for your fleet.
• Quiet Operation: The flexible construction and optimized rib profile minimize noise and vibration during operation, contributing to a more comfortable working environment.
• Cost-Effective Replacement: A direct OEM replacement part that offers high reliability at a competitive price point, making it an ideal choice for warehouse stock and regular maintenance schedules.

FAQ

Q1: How do I confirm this 3288724 belt fits my 6BT engine?
A: The 3288724 is the standard fan belt for the 6BT engine, but it’s crucial to verify your specific application. Check the old belt’s part number printed on its back. If it is 3288724, it is a direct match. For non-standard configurations (e.g., with a different alternator bracket or air conditioning compressor), please consult your engine’s parts manual or contact our technical team with your engine serial number.

Q2: What is the recommended installation procedure for a ribbed belt?
A: Installation is straightforward but requires care. First, ensure the engine is off and cool. Loosen the tensioner pulley (or alternator bracket) to relieve tension on the old belt. Remove the old belt and route the new one exactly as the old one was. The ribs must align perfectly with the grooves on all pulleys. Re-tension the belt to the manufacturer’s specification (usually a deflection of about 1/2 inch under moderate thumb pressure). Over-tensioning can damage the alternator or fan bearings.

Q3: How often should this fan belt be replaced?
A: As a wear item, it is good practice to inspect the belt every 50,000 miles or 2 years, whichever comes first. Replace it immediately if you see signs of cracking, glazing, fraying, or if it begins to squeal. For critical applications like construction equipment, a proactive replacement schedule is recommended to prevent unexpected downtime. Always replace the belt if it has been contaminated with oil or coolant.
