These genuine replacement piston rings seal the crankcase and create the optimal compression to power the lawn tractor engine. Piston rings are constantly exposed to high pressure and temperatures and can wear down or become damaged over time. A worn or broken seal means that the engine will lose compression and power and could become completely disabled if the damage is bad enough. Replacing the piston rings will give the engine the proper seal for optimal performance when OEM parts like this ring set are used. This genuine OEM ring set is manufactured to be used in hundreds of engines for lawn tractors manufactured by Briggs & Stratton and Toro. These rings have multiple locations and applications, depending on the type of engine and tractor in question. The piston rings are sold in a set of four durable rings made of high-quality metal. Always perform engine repairs only after the engine has cooled and when the spark plug has been disconnected for safety.

This O-ring seal is used in all sorts of lawn and garden equipment as a seal for the oil dipstick. It helps seal the system from debris and dirt that could otherwise reach the oil and end up in the motor. Over time, an O-ring will start to shrink, which can result in air and oil leaks and a poorly performing engine. If the O-ring has pits, blisters, or pocks on the surface, it will also need to be replaced.If an O-ring seal is worn, damaged, or clogged, it should be cleaned or replaced before the equipment that houses it is used again. A flat head screwdriver can be used to remove the damaged O-ring. Once the old one has been removed, a new one can be placed into the same position before using the tool.This O-ring seal is designed for lawnmowers, snowblowers, tillers, wood chippers, pressure washers, generators, and leaf blowers.
