Product questions
How many teeth does the Cummins 4851 starter ring gear have?
The 4851 ring gear is listed with 118 teeth. Check the existing gear and confirm the part against your engine and flywheel before ordering.
Will the 4851 ring gear fit my Cummins N14 or NT855?
A flywheel catalogue lists 4851 for a particular N14/NT855 flywheel, but that does not establish fitment for every engine or flywheel configuration. Provide the engine serial number and flywheel part number for verification before ordering.
