This metal ring in your engine, known as the piston ring, seals the gap between the piston and cylinder wall. It makes sure that the gases produced during combustion do not escape and that the engine maintains the pressure it needs to run. If the piston ring is damaged, oil can seep into the combustion chamber, causing your engine to exhibit rough idling and your machine emit blue smoke. To switch out a defective piston ring, detach the old ring from the piston with a screwdriver. When installing the new ring, you may need to compress it to make it fit properly. Please be aware that this genuine OEM replacement part is bought individually. It is recommended that you replace all the piston rings in your machine at once, as they tend to wear down at the same rate. Carefully review your user manual to determine how many rings your machine needs before placing your order.
