3.2.2.9. The block of cylinders and коленвал

Clearing

PERFORMANCE ORDER
1. Remove from the block of cylinders all hinged units and gauges. For clearing it is necessary to get also заглушки. For this purpose drill in заглушках on a small aperture in which screw on the screw – саморезу. Заглушки are taken by pincers for heads of screws, or by means of a shock stripper.
2. Соскребите all rests of a material of linings from the block of cylinders and from a skeleton of covers of radical bearings (in those engines in which the skeleton is provided), being careful not to damage demountable condensed planes.
3. Remove all заглушки oil channels (if are provided). These заглушки have very dense landing, their drilling with the subsequent passage by development 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 маловязким with oil to prevent rust occurrence. Drying process can be accelerated a purge of internal channels the compressed air.
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 rigid brush and hot water (with the temperature excluding burns) with soap or a washing-up liquid. Do not feel sorry for time and carefully wash out the block of cylinders. Irrespective of a way of clearing very carefully wash out all internal lubricant channels and well dry. Walls of cylinders oil to prevent rust occurrence.
7. Carving apertures in the block should be cleared that will provide exact indications of the moment of an inhaling at assemblage. Banish a carving a tap as it will allow to clear carving apertures of a dirt, traces of corrosion and hermetic rests, and also to restore a carving. At possibility blow apertures a stream of compressed air for removal of the rests of a material from passage by a tap.

The prevention

Good results are given by injection in apertures of vodno-dispersive greasings under a high pressure which are available on sale in long баллончиках with аэрозолью. At clearing in such a way dress goggles.


8. Establish in the block of cylinders new заглушки, preliminary having greased with their suitable hermetic.
9. If engine assemblage is postponed, cover the block of cylinders with a polyethylene film to prevent hit of a dirt and rust formation. Grease all demountable condensed surfaces that will protect them from corrosion.

Condition 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 expedient to address to the expert. 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, the fillet 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.
5. Designations of dimensional groups of cylinders (are specified by arrows) are stamped on a demountable plane of the block under a lining of a head of cylinders, near to cylinders.
6. Check up a condition of pistons and rings (subsection 3.2.2.12 see). The backlash between the piston and the cylinder is defined as a difference of measured diameters of the cylinder and the piston.
7. Compare results with specified in (subsection 3.2.1.1 see). 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. In spare parts pistons only – 0,2 mm are delivered one repair size.
8. 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.
9. 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.
10. Хоннингование it is usually carried out with the help хоннинговальной heads with подпружиненными stones which is inserted into an electrodrill. It is necessary to prepare also kerosene or oil for хоннингования and rags. In process хоннингования periodically move the tool upwards and downwards in the cylinder, plentifully greasing cylinder walls.
11. After хоннингования on a surface of walls of the cylinder the structure of the thin lines crossed at an angle nearby 60 should be formed. Do not remove a superfluous material, хоннингование finish right after surface operational development. If new pistons it is necessary to have in view of are established that the manufacturer of pistons processing of walls of cylinders with a bit different corner of crossing of lines can be recommended. In this case observe the instruction of the manufacturer of pistons.
12. It is forbidden to get from the cylinder хоннинговальную a head during rotation, – at first wait a full stop. Upon termination of carefully wipe the cylinder from oil. In the absence of the adaptation for хоннингования or if you are not assured that can qualitatively execute this operation, it is necessary to address in a workshop, where cylinders отхоннингуют for a moderate payment.
