Clearing

PERFORMANCE ORDER
1. Remove from the block of cylinders all hinged units, turn out gauges. Get заглушки for what drill in заглушках apertures in which screw on the screw-samorezu and take pincers for heads of screws.
2. Cautiously clear the block of cylinders of the rests of a material of linings.
3. Remove all заглушки oil channels (if are provided). These заглушки are wrapped very densely, their drilling with the subsequent passage by a tap therefore can be necessary. At engine assemblage all заглушки replace.
4. In case of strong pollution of a surface of the block of cylinders clearing by steam is required.
5. After steam processing of the block once again repeat clearing of lubricant apertures and channels. Wash out all internal channels of the block of cylinders warm water until then yet pure water will not start to follow. Carefully dry the block and grease all demountable and шлифованные surfaces to prevent corrosion.
6. If the surface of the block of cylinders is polluted moderately it is possible to be limited to a sink of the block of cylinders a hot soap solution.
7. Clear carving apertures and banish a carving a tap.
8. Turn new заглушки, preliminary having greased with their hermetic.
9. If engine assemblage is postponed, grease planes of the block of cylinders and cover all block with a polyethylene film.

Check

PERFORMANCE ORDER
1. Visually check up presence on the block of cylinders of cracks and corrosion traces. Check up a condition of carvings in apertures, note places with the broken carving. If there were suspicions on leak of a cooling liquid in the block of cylinders the block should be tested for tightness for what it is necessary to address in a workshop. At detection of defects repair the block (if it probably), or replace.
2. Check up presence having chopped off and задиров on internal surfaces of cylinders. Check up fillet presence in the top part of the cylinder which specifies in the strengthened deterioration of the cylinder.
3. Check up presence having chopped off and задиров on internal surfaces of cylinders.
4. Measure internal diameter of the cylinder in 10 mm from edge of the cylinder in parallel and perpendicularly engine axes. Repeat measurements on distances of 60 and 100 mm from cylinder edge. By results of these six measurements define конусность and ovality of the cylinder.

The prevention

The designation of dimensional group is put by punching in the basis of the block of cylinders from outside a flywheel. It is put two sets of designations - from four figures which specify in an accessory of internal diameter of the cylinder to the given dimensional group, and the fifth figure which concerns beds of radical bearings коленвала in the block of cylinders. The first in a designation for cylinders specifies in dimensional group of 1st cylinder, and 4 – on dimensional group of 4th cylinder (fig. the Designation of dimensional groups of cylinders and radical bearings коленвала see).


5. Check up a condition of pistons and rings. Define a backlash between the piston and the cylinder as a difference of measured diameters of the cylinder and the piston.
6. Compare results to the standard. If any of the measured values leaves for standard limits the cylinder needs to be chiseled under the next repair diameter and if it is impossible it is necessary to replace the block of cylinders. To undertake the most correct further actions, consult at the expert.
7. If a condition of pistons and cylinders satisfactory, and deterioration is that that a backlash between the piston and the cylinder within norm replacement of piston rings is required only.
8. In this case cylinders are exposed only хоннингованию which provides the best to extra earnings of piston rings and their tight прилегание to walls of cylinders (it is carried out on a car repair shop).
