Dismantle

PERFORMANCE ORDER

The prevention

Коленвал it is possible to remove only after dismantle of the engine from the car. Preliminary remove a flywheel (or a leading disk), a pulley-uspokoitel, a belt (chain), the pallet, маслоприемник, the oil pump, a forward cover and rods with pistons.


1. Preliminary check up axial люфт коленвала.
2. Displace коленвал towards a back part of the engine, having made the maximum effort, and in this position establish an indicator scale on a zero.
3. Then push a cranked shaft towards a forward part of the engine and consider indicator indications. The size axial люфта is equal to distance on which the shaft has moved. If axial люфт exceeds standard value check up deterioration of persistent surfaces of cheeks коленвала. If their deterioration insignificant люфт it should be corrected by replacement of radical loose leaves with the new.
4. In the absence of a display head люфт it is possible to measure by means of a set probeов.
5. Cautiously displace коленвал towards a forward part of the engine and measure axial люфт, laying probeы between a cheek коленвала and an end face of the persistent radical bearing.
6. Check up presence on covers ориентационных the marksman and marks of number of the cylinder. Usually covers are numbered beginning from a forward part of the engine, available arrows should be turned towards a forward part of the engine. If marks are absent, начерните labels.
7. Release bolts of covers on 1/4 turns at one time in, until then while bolts not begin to turn away by hand. At assemblage bolts should be turned on former places. Keep in mind that on a part of engines bolts are used as pins which also should be turned on former places.
8. Cautiously displace covers and remove them together with loose leaves.
9. Cautiously remove коленвал. Leave loose leaves in проточках the block of cylinders and covers. Put covers on the places and tighten bolts by hand.

Check

PERFORMANCE ORDER
1. Wash out a cranked shaft solvent and dry, clean oil channels, clear necks and remove надфилем agnails.
2. Check up a condition of necks of a shaft, presence of cracks, hollows, задиров. Check up a roughness of necks, потерев about them a copper coin. If there are traces necks follows перешлифовать. It is recommended to execute internal дефектоскопию коленвала.
3. Measure diameter of necks in several places and define конусность and ovality.
4. At appreciable damages коленвал follows перешлифовать and to replace loose leaves repair.
5. If on necks under epiploons the deep flute from a working edge of an epiploon was formed, there are scratches or other damages коленвал it is recommended to replace, or проконсультроваться in car-care centre where a neck it is possible to chisel and напрессовать the plug.
