4.1.16.3. Check of pistons and rods

THE GENERAL DATA

Before check of pistons with rods remove from pistons piston rings and carefully clear pistons.

For removal of piston rings from pistons unclench a ring and insert under a ring in regular intervals on a circle two or three old edges probeа and on them shift a ring from the piston. Be cautious, do not scratch the piston the ring ends. Rings very fragile also can burst, if them to unclench very strongly. Working edges of piston rings very sharp, therefore address with them very cautiously not to be cut. Hold each set of rings together with pistons for their repeated installation on the places.

PERFORMANCE ORDER

1. Clear all traces of a deposit from the top part of the piston. 2. Remove a deposit from flutes under piston rings in the piston, using an old piston ring. 3. After touch removal clear the piston with a rod corresponding solvent and wipe dry. 4. Carefully examine each piston on presence of cracks round a skirt and apertures under a piston finger. 5. Check up deterioration on a skirt of the piston, an aperture in a piston head, and also presence прожога in the top part of the piston. 6. Traces of dot corrosion on the piston specify that the cooling liquid got to the combustion chamber. It is necessary to find the reason of hit of a liquid in the chamber of combustion and to eliminate it. 7. Measure diameter of the piston. 8. Define a piston backlash in the cylinder for what from diameter of the cylinder take away diameter of the piston and divide into two. 9. Check up each rod on deterioration and presence of cracks, and also form distortion. 10. Rods usually do not demand replacement if before it there was no engine jamming.
