To remove a compression ring, first use a ring expander to spread the ring. Slide the piston ring compressor over the piston and place the expander into the ring groove. Tighten the compressor to expand the ring until it can be slipped off the piston. Inspect the ring for wear and damage, and replace it if necessary. Always follow proper safety precautions and use the correct tools for the job.

Understanding Engine Components Involved
Pistons
The pistons are the workhorses of the engine, moving up and down inside the cylinders to compress and burn the fuel-air mixture. They’re made of lightweight materials like aluminum or iron and have a ring of grooves cut into their outer surface.
Compression Rings
Sitting in these grooves are the compression rings. Their job is to seal the combustion chamber and prevent gases from escaping past the piston. These rings are usually made of steel and have a tapered shape to create a tight seal against the cylinder wall.
Oil Control Rings
Just below the compression rings are the oil control rings. These rings scrape excess oil off the cylinder walls as the piston moves up and down. This helps keep the engine running smoothly and prevents oil from burning in the combustion chamber.
