Sierra 18-5656 Starter Drive Assembly, 10 Tooth, Replaces 68575, White

The Sierra 18-5656 is a 10 tooth starter drive assembly engineered to engage the flywheel ring gear and transmit starter motor torque during engine cranking. The drive features a machined exterior finish in white and is built to Sierra's standard fit, form, and function specifications so it installs and operates the same as the original equipment part it replaces. As the engagement point between the starter motor and the flywheel, the drive assembly is a wear item that spins and retracts with each start cycle, so its threads, springs, and pinion gear teeth need to be in good condition for reliable cranking. This drive assembly directly replaces OEM part number 68575, making it a straightforward like-for-like swap when the original drive is worn, chipped, or no longer engaging smoothly. Sierra parts are backed by Sierra's customer satisfaction warranty, giving buyers confidence in fit and durability. Always confirm the 10 tooth pinion count and part number 18-5656 match your existing starter drive before ordering, since drive assemblies are built in different tooth counts for different starter applications and are not interchangeable across tooth counts.
