Installation
Installing Piston Rings
Component view
1. Open oil scraper spring. In order to do this, pull apart the oil scraper spring at the gap. The gap can be recognized by the tighter winding of the spring.
2. Insert oil scraper spring. Insert the oil scraper spring into the lowest ring groove and then push together.
3. Align the gap of the oil scraper spring. The gap of the oil scraper spring must be installed offset by approx. 60° into the twist lock of the second ring groove.
4. Insert piston ring into the piston ring pliers. Make sure that, when installed, the designation of the piston rings is pointing in the direction of the piston crown.
5. install piston rings. This will start the oil scraper ring. Place the gap of the oil scraper ring into the middle point of the piston ring pliers. Carefully stretch the piston ring with the help of the pliers to a point where this can be placed over the pistons into ring groove 3. The gap of the oil scraper ring must be installed offset by exactly 180° into the gap of the oil scraper spring (or offset by 120° into the twist lock of the second ring groove). Make sure that the oil scraper spring is in the oil scraper ring. Then install the stepped taper faced ring (indicated by the lower recess on the outer edge). With the help of the piston ring pliers, insert the stepped taper faced ring into the second ring groove in such a way that the designation "TOP" is pointing towards the piston crown. The twist lock of the second ring groove must be between the gap of the stepped taper faced ring. Insert the taper faced ring into the ring groove in such a way that the designation "TOP" is pointing toward the piston crown.
6. Check that the piston ring is correctly seated and positioned. Make sure that the oil scraper spring is inside the oil scraper ring. In terms of the piston ring in the ring groove 2, the twist lock must be on the inside of the gap and the designation "TOP" must be pointing towards the piston crown. The highest piston ring must be installed in such a way that the designation "TOP" is pointing towards the piston crown. The gaps of the individual piston rings must always be offset by 120°.
