Removing Piston Rings




Tools


NOTE: Combustion deposits on the piston crown are not to be removed mechanically.












1. Place the removed pistons on a clean surface and look for the gap of the piston rings.







2. Remove the piston rings starting from the piston crown. In order to do this, place the middle point of the piston ring pliers into the gap of the relevant ring. The holding arms of the piston ring pliers should clasp the piston ring from above. Only open the piston ring as much as is needed to remove the piston ring from the groove.







3. Remove piston ring from the pliers. Relieve the piston ring pliers and remove the piston ring from the pliers.







4. Look for the gap of the oil scraper spring. In the ring groove of the oil scraper ring is another oil scraper spring. Look for the gap here. This is exactly opposite the tighter winding.







5. Pull apart the oil scraper spring at the gap.







6. Remove the oil scraper spring from the third ring groove.
