To check the quality of work, it is necessary to install in
place of the removed parts and devices, start and warm the
engine, listen to its work. With properly adjusted gaps knocks
in the valve mechanism should not be.
The size of the clearance on the cold engine ZIL-130 is
0,2 .... 0,25 mm (do similarly to the above method).
After the completion of the laboratory work, the results
of measurements of the thermal clearance of the inlet and outlet
valves, the moment of tightening the nuts of fastening the head
of the cylinder block and the shaft of the shaft must be inserted
into the table, compared with the normative data, perform the
analysis and present the findings.

11.4 Individual task. Each student, on the basis of a
positive assessment, receives an individual task for laboratory
work at a poll in the class.
12.4.1 Draw a gas distribution diagram for the given
engine.
12.4.2 Describe the structure of the GDM of the given
engine.
12.4.3 Draw a kinematic diagram of the camshaft GDM.
12.4.4 Give the scheme and describe the structure and
principle of the system of changing the phase of the GDM.

11.5 Control questions:
1. Name the order of cylinder operation of the KAMAZ-
740 engine.
2. Describe the process of adjusting the thermal gaps of
the given engine.
3. Name the general structure of GDM.
4. Describe the structure of the system of changing the
phases of the distribution of fuel and lubricants.
5. Draw a gas distribution diagram for the given engine.
