CUMMINS ISB 24V Belt Tensioner Pulley For Sale (Part 3976833)
About This Cummins ISB 24V Belt Tensioner Pulley
This is a good, used tensioner pulley for the Cummins ISB 24V Belt, carrying part number 3976833. An idler, tensioner, or accessory pulley guides the drive belt and helps maintain the alignment or tension needed to operate engine accessories. A worn bearing, damaged groove, bent mounting surface, or failed tensioning mechanism can cause noise, belt tracking problems, slipping, or belt failure. Pulley diameter, groove count, offset, mounting, and belt routing vary by application, so visual similarity alone does not prove fitment. Compare the installed component, page photos, and any listed part number before ordering. The part is inspected and tested before it ships, identified by its stock number (323443), and backed by included warranty coverage. Freight ships nationwide, quoted to your delivery ZIP. Use the page photos and listed details to compare it carefully with the component being replaced before purchase. Have your engine's year, make, model, and application ready and call (800) 696-5459 to confirm fitment before ordering.
