Piston rings

Setting

PERFORMANCE ORDER

1. Check the play in the joints of the Rings.
2. Lay the pistons assembled with rods and new piston rings in such a manner that the set of rings corresponded to the cylinder, which will be measured by the gap in the rings that checks will be installed.
3. Insert the upper ring of the first cylinder and push the piston head inside, so that the ring inside cylinder became perpendicular to its axis. Push the ring to a depth at which the edge of the piston skirt becomes equal to the split plane of the cylinder block, then remove the piston.
	4. Measure the clearance probe and compare the result to the standard.
5. If the gap is too small, then gently file off the ends of the ring with a thin needle files.
6. If the clearance is above the norm, make sure that the ring corresponds to the given motor and the cylinder size group.
7. Repeat for each ring of the first cylinder and other cylinders for rings. The rings and plugs corresponding to one and the same cylinder store together.
8. After selection of rings, measurement and adjustment of the gap of the ring can be mounted on the pistons.
A warning Always follow the instructions of the manufacturer of the Rings, as different manufacturers recommend different procedures for installation of rings on the piston. Do not confuse the upper and lower compression rings which have different profiles.
9. The first set oil ring.
	10. Install the expander in the groove.
	11. Then, between the expander and platforms piston groove set in order the upper and lower wheels oil ring.
12. Install the lower compression ring.
	13. Install the top compression ring it properly oriented. If the ring has a symmetrical cross section, then place it so that the identification label is facing up.
	14. Place joints in line.
15. Set the rings on the other pistons.
