The nut has the left woodcarving. |
|
|
Do not result three pins of a rotor. |
To check
|
|
- There compensate for a gentle scraper the superior surfaces of pistons of deposits from coal, compensate for the inter-connected surfaces of the cylinder block and leaders of the cylinders of the placing then the punch remains the dirt remains the compressed air and the oil of punch of sculpting openings below pins of the leaders' fixation of cylinders.
- Compensate for a brush of wire of the camera of combustion of deposits from coal then cylinders leaders do the dish a gentle brush with the solvent.
- Through the rifle small rod they compensate for the captures of direction of valves. Clear leaders of valves of deposits from coal valves then clear a gentle brush.
- Through an equal flat sovereign they measure not planeness of leaders' surfaces of the inter-connected cylinders to the cylinder block. If necessary a head of cylinders substitutes.
- Measure the internal diameter of the captures of direction of valves, the diameter of nucleuses of valves (in several sections) then they calculate a slit of oil. Compare all the data obtained with demands of Specifications of the Chief Dvigatel, if necessary a guide substitutes to capture and / or the valve.
- Measure a corner of facet of valve, the height of a consolation of a chief of Kapan, the length full of the valve and check the superior surface of a nucleus of the valve of the use. Compare all the data obtained with demands of Specifications of the Chief Dvigatel, if necessary the valve substitutes or grind the superior surface of a nucleus (but not less than what to the least admissible length of a nucleus!).
|
|
-
Perforate saddles of valves in an angle the 45th hail. also check concentricity of saddles of valves and facets of valves, and also width of his interface. If necessary a valve saddle perforates.
|
- Supporting valvate springs against a metal corner, vertical will measure the size of detour of face of spring end of. It will measure the spring length in a free state then they measure a spring tension in the moment of the compression he to the 33,8 mm length. Compare all the data obtained with demands of Specifications of the Chief Dvigatel, if necessary it substitutes springs valvate.
- It will measure a radial thrashing of the central neck and the diameter of necks of each axle. Measure height of cames and a play of axial side of axles. Compare all the data obtained with demands of Specifications of the Chief Dvigatel, if necessary the axle substitutes or check a slit of oil of his loads.
- Check loads of axles of the existence of flakings and carve. If necessary there substitutes coverings of loads and a head of joined cylinders.
- The clear necks of a covering of loads of axles then measure a slit of oil of loads through the play of Plastigage, when held tight pins of the fixation of coverings of loads with the effort of 16 nanômetros. Compare the data obtained with demands of Specifications of the Chief Dvigatel and if necessary there substitutes the axle and / or the coverings of the loads and a head of joined cylinders.
