Washer-spring Bell
Part #736-0270
This OEM spring bell washer is a small, circular piece of metal that is shaped like a cone and has an inside diameter of 1/4 of an inch. It is also called a Belleville washer or a disc spring, and it is used in lawn equipment to help spread out pressure and absorb shock between parts. If a washer is broken, it may look flattened or distorted, and your machine may make unusual vibrations or noises. If you do not replace a damaged spring bell washer, your machine will wear out faster because there will be nothing to cushion its parts. To remove a washer, you can use pliers or a flathead screwdriver to pry it from your machine. If it is difficult to remove, you can use a penetrating oil to loosen it first. To make sure you purchase the correct number of washers, which are sold separately, check your user guide to see where they are needed in your machine.
