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.
PERFORMANCE ORDER |
|
1. Previously check an axial side play of the crankshaft. 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. 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. |
2. If the axial side play exceeds standard value, then check wear of persistent surfaces of cheeks of the crankshaft. If their wear insignificant, then it is necessary to replace half rings |
|
3. In the absence of an indicator head the side play can be measured by means of a set of probes. 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 the surface of the 3rd (persistent) radical bearing on 4-cylinder engines, or the 2nd radical bearing (V6). |
|
4. Check existence on covers of orientation arrows and markings of number of the cylinder (are specified by an arrow). Usually covers are numbered beginning from a forward part of the engine, orientation shooters are turned towards a front. |
|
5. If marking is absent, then put tags with a stamp. Tags are applied on inflow near a bolt head. |
|
|
6. Release bolts of covers on 1/4 turns at one time in the sequence return specified (at the left – 4-cylinder engines, on the right – engines 6V) until bolts do not begin to turn away by hand. On engines 3VZ-FE (V6) of a cover are executed in the form of a uniform framework. Designate the provision of hairpins which are used as the directing pins. |
7. Carefully displace covers and remove them together with insert(s). |
