2.37. Cranked shaft


Check of a lateral gap of a rod


To remove or disconnect

1. Engine.
2. To merge oil.
3. To establish the Engine on the stand.
4. To unscrew spark plugs 20.
5. A pulley 145 with a nave.
6. Cover of a gear belt.
7. A gear belt 44, having weakened bolts of fastening of the water pump.
8. Flywheel 116.
9. Oil pallet 125.
10. Cogwheel of 141 cranked shaft.
11. Back cover of a gear belt.
12. Oil pump 137.
13. Covers of 157 rods with loose leaves, previously having marked.
14. To remove pistons 160 with rods 159 from necks of a cranked shaft.
15. Covers of 122 radical bearings with loose leaves 120 and 121. Previously to mark details.
16. Cranked shaft.

To clear

1. Oil, dirt and deposit.
2. Oil channels from jams and deposits.

To check

1. Shponochny flute.
2. Carving.
3. Necks of bearings and persistent fillets on existence:
      – cracks;
      – metal vykrashivaniye;
      – deepenings;
      – roughnesses;
      – flutes;
      – overheat traces.

To examine the corresponding loose leaves on existence of impregnations of extraneous particles, in the presence of similar defects it is necessary to find out an origin of these alien particles.

In the presence of cracks or other deep defects of workers поверхнос ty it is necessary to replace a cranked shaft. Small roughnesses can be smoothed down the thin skin moistened in engine oil. Teases delete by means of thin grinding whetstone.

To measure

Necks of a cranked shaft. To measure deviations from a tsilindrichnost (konusnost) and kruglost (ovality) by means of the indicator or a micrometer. If the sizes and a shape of necks are in admissible limits, it is necessary to write down results of measurements for the subsequent selection of a set of loose leaves. If a condition of necks unsatisfactory, it is possible to restore a shaft rabosposobnost repolishing of necks. Shaft with nakatanny galtel are subject to replacement.

To check an arrangement of ledges of the radical bearing. If they are located not to the line, a cranked shaft will bend, and is subject to replacement.

To establish or attach

1. New loose leaves 120,121, cranked shaft 119.
2. Covers of 122 radical bearings with new loose leaves. Not to tighten bolts 123. Previously to oil loose leaves.
3. To establish heads of rods with new loose leaves 158 on necks of a cranked shaft.
4. Covers of rods with new loose leaves. Not to tighten shatunny bolts 156. Previously to oil loose leaves.
5. In hammer blows with rubber brisk on the ends of a cranked shaft to center persistent bearings 121.
6. To tighten bolts of radical bearings the moment of 50 Nanometers., then in addition to tighten them turn on a corner 45 °–60 °. To check an axial gap of a cranked shaft. It should be within 0,07–0,30 mm.
7. To tighten bolts of shatunny bearings the moment of 25 Nanometers., then in addition to tighten them turn on a corner 30 °.
8. To measure lateral gaps of all rods. Gaps should be within 0,07–0,242 mm.
9. Oil pump 137.
10. New forward consolidation коленчато го a shaft, using the KM-417 adaptation.
11. Back cover of a gear belt.
12. Cogwheel 141.
13. Oil pallet 125.
14. New back consolidation 117.
15. A flywheel to tighten bolts the moment of 35 Nanometers, then in addition to tighten turn on 30 °–45 °.
16. Gear belt and cover.
17. A pulley to tighten bolts the moment of 55 Nanometers.
18. Spark plugs.
19. To establish the Engine on the car.
20. To fill in engine oil.
