CUMMINS ISX15 Timing Gear For Sale (Part 3686778)
About This Cummins ISX15 Timing Gear
This is a good, used timing gear for the Cummins ISX15, carrying part number 3686778. Timing and accessory gears transfer drive through the engine's gear train so the camshaft, pumps, and other components operate in the required relationship. Worn teeth, chips, cracks, damaged keyways, or excessive backlash can cause noise, timing problems, or further internal damage. Tooth count, diameter, hub design, and mounting are engine-specific, so a similar-looking gear may not interchange. Compare the original gear, page photos, and any listed part number before ordering. The part is inspected and tested before it ships, identified by its stock number (324628), 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.
