Ariens 52004200 Gear Case 22 Inch Iron Small Top Load

Product Description

The ARIENS 52004200 is a cast iron gear case designed for 22-inch walk-behind lawn and garden equipment. The gear case houses and protects the drive train components that transfer power from the engine to the wheels or auger, depending on the application. Its iron construction provides the durability required for the mechanical stresses of continuous drive engagement. This part is installed by equipment technicians and experienced service professionals performing drivetrain repairs or seasonal overhauls on Ariens outdoor power units.

This gear case is intended for small top-load configurations on 22-inch Ariens walk-behind units. It is a direct OEM replacement component used when the existing gear case shows wear, cracks, stripped threads, or internal gear damage that compromises drive performance. Proper fitment depends on confirming the correct unit model and configuration before installation.

Key Features

• Cast iron construction for high mechanical durability under drivetrain load
