Mcculloch Lawn Mower Engine

A combustion engine will create a lot of pressure by igniting fuel and air with a spark. It features pistons beneath the valves and the cylinder block. Between these areas are the piston rings that have many purposes that include keeping gas compression between the piston and the wall of the cylinder, keeping a layer of lubrication on the inside of the engine, allowing adequate heat transfer, and supporting the piston inside the cylinder. This replacement piston ring is designed for use in a long list of edgers, trimmers, and blowers. It is compatible with Husqvarna, Poulan, and Craftsman machines. This is an OEM replacement part that will require a complex set of steps to install properly. It will require the use of torque wrenches, plug wrenches, pliers, screwdrivers, a mallet, and more to do the repair. It ships individually.

Combustion engines operate because of the chambers that seal in the tiny explosions caused by fuel, air and a spark. The pistons are part of the process of taking power from those explosions, and the piston rings seal the combustion chamber so that all of the gases created remain inside of the engine's crankcase. This replacement piston ring will ensure that a chainsaw's engine can do that, as well as maintaining the right amount of oil between the piston and the cylinder wall. An OEM replacement part, this piston ring works with Craftsman and Husqvarna chainsaws, among others. It will require a wrench set, screwdriver and a pair of pliers to make the replacement.
