3.16.24. Installation of pistons
THE GENERAL DATA

Correct arrangement of pistons before installation of internal lock rings of a piston finger


PERFORMANCE ORDER
1. Establish the engine on a workbench in the same position as it is and in the car.
2. Establish new lock rings of a piston finger in an internal flute of a piston finger of each piston (fig. the Correct arrangement of pistons before installation of internal lock rings of a piston finger see).
3. Check up that locks of piston rings are correctly located on the piston. Grease a skirt of the piston and piston rings with pure engine oil. Using the adaptation for compression of piston rings, compress piston rings on the piston of the first cylinder.
4. Turn a cranked shaft of the engine so that rods of the first and second cylinders were established in the bottom dead point. Establish the top heads of rods precisely on the cylinder centre.
5. Insert the piston with the adaptation compressing rings, into the top part of the first cylinder. Thus inscription UP or TOP should be directed upwards.
6. Using wooden брусок or the hammer handle, press the piston into the cylinder.
7. Move the piston until the aperture in the piston under a piston finger will not be combined with an aperture in the top head of a rod. Apertures under a piston finger are visible through a technological aperture in the block of cylinders. If necessary, using a core of the corresponding diameter, level apertures under a piston finger.
8. Grease a piston finger with pure engine oil and establish it through a technological aperture in the piston and a rod.
9. Establish an external lock ring of a piston finger in the piston.
10. Similarly establish the piston of the second cylinder. Apply a thin film hermetic on a lining of a technological stopper and establish linings and stoppers in the block of cylinders.
11. Turn a cranked shaft of the engine so that rods of the third and fourth cylinders were established in the bottom dead point.
12. Repeat operation on installation of pistons and piston fingers of the third and fourth cylinders.
