THE GENERAL DATA

Cranked shaft

1 – a bolt, 54–59 Nm;
2 – the radical loose leaf;
3 – a cranked shaft;
4 – the radical loose leaf;
5 – a cover of the radical bearing of a cranked shaft

Removal

PERFORMANCE ORDER
1. Remove a gear belt, a forward cover, a head of the block of cylinders, a flywheel and the oil pallet.
2. Remove a back cover of the block of cylinders and a back sealing ring.
3. Mark covers of rods and rods according to cylinder number in which they are established.

The prevention

Note rods and covers of rods so that at installation they have occupied correct position and a direction. At wrong installation of rods greasing giving in шатунные loose leaves that will lead to their fast damage will be broken.


4. Turn a cranked shaft of the engine so that pistons of the second and third cylinders were established in the bottom dead point and similarly mark rods and covers of rods.
5. Turn away a nut of fastening of a cover of a rod and easy blows of a plastic hammer bring down a cover.
6. Uncover a rod.

The prevention

For protection of necks of a cranked shaft dress on bolts of fastening of covers of rods pieces of a rubber or plastic tube.


7. Wooden бруском or the hammer handle push out the piston with a rod from the cylinder.

The prevention

Note an arrangement and orientation of covers of radical bearings of a cranked shaft further to establish them on the initial places.


8. Turn out bolts, remove covers of radical bearings and a cranked shaft. Hold radical loose leaves together with corresponding covers of radical bearings of a cranked shaft.

Check

PERFORMANCE ORDER
1. Check up necks radical and шатунных bearings of a cranked shaft on absence of deterioration and development.
2. Check up lubricant apertures of a cranked shaft on absence of a contamination.
3. Establish the first and last necks of radical bearings of a cranked shaft on V-shaped blocks.

4. Establish a measuring head of the indicator of hour type on an average neck of the bearing of a cranked shaft and establish an indicator scale on 0. Turn a cranked shaft and measure its palpation. If palpation exceeds nominal palpation, replace a cranked shaft.

Palpation: 0,04 mm

5. In the presence of development or ovality перешлифуйте a cranked shaft.
6. Repolishing of necks of a cranked shaft spend only till next repair size.
7. If a cranked shaft перешлифован for the repair size of +0,50 mm, spend heat treatment of a shaft for increase in its durability.

Diameters of necks of radical bearings of a cranked shaft:
1st repair size (+0,25 mm): 49,688–49,706 mm
2nd repair size (+0,50 mm): 49,438–49,456 mm
3rd repair size: (+0,75 mm): 49,188–49,206
Diameters of necks шатунных bearings of a cranked shaft:
1st repair size (+0,25 mm): 39,690–39,706 mm
2nd repair size (+0,50 mm): 39,440–39,456 mm
3rd repair size (+0,75 mm): 39,190–39,206 mm
