Timing gears can wear on the teeth and should be replaced at rebuild time to remove slack in the chain and restore original timing. This is an aftermarket replacement for the standard single-row "simplex" timing gears on any A+ classic Mini engine. Includes crank and cam sprockets and timing chain for little more than the cost of the cam gear alone.
Tensioner 12G2621 sold separately.
