3.16.13. Block of cylinders of the engine

GENERAL INFORMATION

Places of measurement of diameters of cylinders


Plate arrangement with sizes

On the top part of the block of cylinders of the engine there is a plate with the indication of the size of the main neck of a cranked shaft and the indication of diameter of boring of the cylinder of the engine.

Cleaning

PERFORMANCE ORDER
1. Remove all traces of laying from the interfaced surfaces of the block of cylinders of the engine.
2. Remove all caps of the oil highway. At installation use new caps.
3. The most polluted places clear the ferry.
4. Clear all lubricant openings and the oil highway. Wash out all internal channels a stream of warm water until water does not leave pure.
5. It is necessary to drain completely the block of cylinders and to grease with a thin butter layer all interfaced surfaces for prevention of emergence of corrosion. Also grease engine cylinders. If there is a compressed air, use it to accelerate process of drying and to blow all lubricant openings and highways.
6. Carefully clear all carving openings, using a tap with the corresponding carving then blow openings compressed air.
7. Install traffic jams to the oil highway in the block of cylinders of the engine and reliably fix them.
8. If the engine is not subject to immediate assembly, close the block of cylinders a big plastic bag to protect it from pollution.

Check

PERFORMANCE ORDER
1. Visually check the block of cylinders for corrosion existence. Check integrity of a carving in carving openings.
2. Check diameter of cylinders of the engine for wear on existence of a step in the top part of the cylinder.
3. In the presence of the measuring tool measure diameter of a sleeve of each cylinder in the top part (under a wear step) in the center and at the basis parallel to an axis of a cranked shaft (see rice. Places of measurement of diameters of cylinders.
4. Measure length of a special template.
5. Then perform the same measurements perpendicular to an axis of a cranked shaft and compare them to specifications.
6. Repeat procedure of measurement on other sleeves of cylinders.
7. Using a steel ruler and an edge of the probe, check planeness of the interfaced surface of the block of cylinders of the engine.
