The crankshaft can be removed only after removal of the engine from the car. At the description it is supposed that the conducted cam-shaft gear wheel, a tube of the index of level of oil, the oil pump and pistons assembled with rods are already removed from the engine a flywheel (or a drive plate of the hydrotransformer). Before dismantling the crankshaft, it is necessary to remove the holder of a back epiploon.
| PERFORMANCE ORDER
||1. Before dismantle of a bent shaft check an axial side play. Install the indicator so that his leg was parallel to an axis of a bent shaft and touched one of his cheeks.
| 2. Displace a bent shaft towards a back part of the engine, having made the maximum effort, and in this situation establish an indicator scale on zero. 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 the crankshaft. If wear insignificant, then a side play has to be compensated by installation of new persistent half rings.
||3. In the absence of an indicator head it is possible to measure a side play by means of a set of probes. Carefully displace the crankshaft towards a forward part of the engine. Lay the probe between a cheek of the crankshaft and the surface of the 3rd (persistent) radical bearing and measure an axial side play.
|4. Check marking on covers of radical bearings which has to correspond to number of the cylinder. Usually covers are numbered beginning from a forward part of the engine. If marking is absent, then put tags with a core. Release each of bolts of covers of radical bearings on 1/4 turns at one time, in the sequence, return specified (see rice. The sequence of an inhaling of bolts of covers of radical bearings) until bolts do not begin to turn away by hand.
|5. Easy blows of the hammer through a soft pro-rate get moving forward covers of radical bearings and remove them from the engine. If necessary it is possible to insert bolts of fastening into covers and to work with them as levers. Do not allow loss of the radical bearing if it remains in a cover.
|6. Carefully get a bent shaft from the block of cylinders. It is recommended to do it together with the second person as a shaft quite heavy. Install covers of radical bearings together with bearings on the block of cylinders in a former order, tighten bolts by hand.
