3.5.12. Pistons and rods


Piston and rod

1. Lock ring

2. Piston finger

3. An arrow on a piston head

4. Piston

5. Rod

6. Rod label


1. Before check of pistons with rods remove from pistons piston rings and carefully clear pistons.
2. For removal of piston rings from pistons unclench a ring and insert under a ring evenly on a circle two or three old edges щупа and on them shift a ring from the piston.


Be careful, 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 carefully not to be cut. Hold each set of rings together with pistons for repeated installation them on the places.

3. Clear all traces of a deposit from the top part of the piston.
4. Remove a deposit from flutes under piston rings in the piston, using an old piston ring.
5. After removal of a raid clear the piston with a rod the corresponding solvent and wipe dry.
6. Carefully examine each piston on existence of cracks round a skirt and openings under a piston finger.
7. Check wear on a piston skirt, an opening in a piston head, and also burned in the top part of the piston.
8. Traces of dot corrosion on the piston specify that cooling liquid got to the chamber of combustion. It is necessary to find the reason of hit of liquid in the chamber of combustion and to eliminate it.
9. Measure diameter of the piston.
10. Define a piston gap in the cylinder for what from diameter of the cylinder take away diameter of the piston and divide into two.
11. Check each rod on wear and existence of cracks, and also form distortion.
12. On all petrol engines piston fingers are pressed in the top head of a rod therefore replacement of rods is necessary for making in a specialized workshop.
13. On diesel engines piston fingers are established on sliding landing and fixed in the piston by two lock rings. On these engines pistons and rods can be divided as follows.
14. Using an edge of a thin screw-driver, remove from the piston a lock ring and a hand squeeze out a piston finger. At repeated installation of a piston finger use only new lock rings.
15. Check a piston finger and the bearing of the top head of a rod on wear.
16. Rods usually do not demand replacement if before it there was no engine jamming.
17. On the engine of 1,7 l collect the piston and a rod so that the adjusting label on a piston head (it is specified by an arrow) was from the same party, as a label on a rod (is specified by an arrow).
18. On engines of 2,0 l collect the piston and a rod so that the arrow on a head of the piston showed aside, opposite from a label on a rod.
19. Grease a piston finger and insert it into the piston and the top head of a rod. Check, that the piston easy and freely turned on a piston finger then fix a piston finger new lock rings. Check, that each lock ring was correctly located in a piston flute. On engines of 2,0 l establish lock rings so that their locks were directed up.
20. On engines of 2,0 l the cut of a lock ring should be directed up the piston.
