2.5. Cranked shaft

GENERAL INFORMATION

Cranked shaft

1–bolt, 54–59 N • m;
2–radical loose leaf;
3–cranked shaft;
4–radical loose leaf;
5–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.

Prevention

Note rods and covers of rods so that at installation they occupied the correct situation and the direction. At the wrong installation of rods supply of greasing in shatunny 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. Unscrew nuts of fastening of a cover of a rod and in easy blows of a plastic hammer bring down a cover.
6. Uncover a rod.

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 whetstone or the hammer handle вытолкните the piston with a rod from the cylinder.

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 the corresponding covers of radical bearings of a cranked shaft.

Check

PERFORMANCE ORDER
1. Check necks of radical and shatunny bearings of a cranked shaft on lack of wear and development.
2. Check lubricant openings of a cranked shaft on lack 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 carry out only till next repair size.
7. If a cranked shaft перешлифован for the repair size of +0,50 mm, carry out shaft heat treatment for increase in its durability.

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 of shatunny 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
