Before installation of new piston rings it is necessary to check a gap in their joints.
It is meant that the gap between a ring and a platform of a landing flute is already checked and corresponds to norms.
Spread out pistons assembled with rods and new piston rings in such order that the set of rings corresponded to this cylinder on which the gap will be measured in a joint.
Insert into the first cylinder the top ring and push the piston bottom inside so that the ring in the cylinder became perpendicular to its axis. The ring should be in the lower part of the cylinder, in the situation corresponding to the bottom dead point.
If the gap is more or less established, repeat measurement to be convinced of possibility of installation of a ring.
If the gap is too small, it should be increased, otherwise in the course of operation of the engine there will be a smykaniye of end faces of a ring that can cause serious breakages. The gap in a joint of a piston ring can be increased carefully having filed end faces a thin file. Clamp a file in a vice with soft sponges and carefully move on it a ring, deleting a superfluous material.
The gap can exceed established, but there should be no more than 1 mm.
It is necessary to repeat measurement to be convinced of suitability of a ring.
Repeat measurements for each ring established in the first cylinder, and also for each of the rings established in other cylinders.
After measurement of gaps in a joint of rings and its adjustments, a ring it is possible to establish on pistons.
The maslosjemny ring (the lowermost on the piston) is established to the first.
This ring consists of three details.
After installation of all details of a maslosjemny ring be convinced that top and bottom directing freely are turned in a flute. Place joints of a maslosjemny ring according to drawing.
Following устаналивается average ring (number 2). On this ring the label of "R" which should be turned towards the piston bottom is stamped.
Establish the adaptation for clothing of piston rings, be convinced that labels are directed towards the bottom of the piston and move the corresponding ring to an average flute of the piston. Do not plant ring joints on bigger distance than it is required for its passing over the piston. Instead of the adaptation it is possible to use metal strips.
