PERFORMANCE ORDER

Prevention

The crankshaft can be removed only after dismantle of the engine from the car. Previously remove a flywheel (or a drive plate), a pulley-uspokoitel, a belt (chain), the pallet, an oil receiver, the oil pump, a forward cover and rods with pistons.


1. Previously check an axial side play of the crankshaft.
2. Displace the crankshaft towards a back part of the engine, having made the maximum effort, and in this situation establish an indicator scale on zero.
3. Then push a bent shaft towards a forward part of the engine and consider indications of the indicator. The size of an axial side play is equal to distance to which the shaft moved. If the axial side play exceeds standard value, then check wear of persistent surfaces of cheeks of the crankshaft. If their wear insignificant, then a side play has to be corrected by replacement of radical inserts with new.
4. In the absence of an indicator head the side play can be measured by means of a set of probes.
5. Carefully displace the crankshaft towards a forward part of the engine and measure an axial side play, laying probes between a cheek of the crankshaft and an end face of the persistent radical bearing.
6. Check existence on covers of orientation arrows and markings of number of the cylinder. Usually covers are numbered beginning from a forward part of the engine, the available shooters have to be turned towards a forward part of the engine. If marking is absent, then nachernit tags.
7. Release bolts of covers on 1/4 turns at one time in until bolts do not begin to turn away by hand. At assembly 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. Carefully displace covers and remove them together with inserts.
9. Carefully remove the crankshaft. Leave inserts in pro-points of the block of cylinders and covers. Put covers on the places and tighten bolts by hand.

Check

PERFORMANCE ORDER
1. Wash out a bent shaft solvent and dry, clean oil channels, clear necks and remove with a file agnails.
2. Check a condition of necks of a shaft, existence of cracks, hollows, zadir. Check a roughness of necks, having rubbed about them a copper coin. If there are traces, then necks should be pereshlifovat. It is recommended to execute internal defectoscopy of the crankshaft.
3. Measure diameter of necks in several places and define conicity and ovality.
4. At noticeable damages the crankshaft should be pereshlifovat and replaced inserts 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, then the crankshaft is recommended to be replaced, or to prokonsultrovatsya in car service where a neck it is possible to chisel and napressovat the plug.
