Overview – BELT 178472
178472 is the drive belt used on CUMMINS engines to transmit power from the crankshaft to the fan, alternator and water pump pulley system. We can supply this belt as well as the related family numbers listed below, in stock or available on order – welcome to enquire by part number.
Parts Characteristics
The belt is built to the original length, width and rib profile, with the multi-rib construction matched to the CUMMINS pulley set. The rubber compound and cord reinforcement are selected for the heat and load of the engine accessory drive. The back of the belt has the correct surface for flat idler pulleys. As an OEM-spec belt, it fits the original tensioner travel and pulley grooves without adjustment of the mounting brackets.
Applicable Models & Applications
This drive belt is used on CUMMINS engines for the fan, alternator and water pump drive where the accessory pulley layout matches the original specification. The family reference 178520 covers the same belt duty on adjacent engine builds. Confirm the belt length, rib count and profile against the belt removed from your engine before ordering.
Maintenance & Replacement
Inspect the belt for cracking, glazing, frayed edges and loose rib sections, especially when charging or cooling problems appear. Check belt tension and pulley alignment during regular service. When replacing, release the tensioner, remove the old belt, and route the new belt over every pulley exactly as the old one was fitted, then reapply tension to the original specification. Rotate the engine by hand to confirm the belt tracks correctly.
Price Reference (USD)
The reference price for this BELT (178472) is approximately USD 15 – 80 per unit depending on grade, quantity and shipping destination. This is a planning estimate only – confirm current pricing and availability with our sales team before ordering.

Value & Service
The wrong belt length will not track properly on the pulley set, so we verify 178472 against the original CUMMINS length and rib profile before dispatch. We stock the belt and the family number above, and they can ship together with the tensioner and pulley kit in one tracked order. Our team will confirm the correct belt for your engine before you buy.
