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