GENERAL INFORMATION

Prevention

The crankshaft can be removed only after dismantle of the engine from the car. Previously remove a flywheel (or the leading disk), 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 back part of the engine, having made the maximum effort, and in this situation establish an indicator scale on zero. Then push a cranked shaft towards forward part of the engine and consider indications of the indicator. The size of an axial side play is equal to distance on which the shaft moved.
2. If the axial side play exceeds standard value, check wear of persistent surfaces of cheeks of the crankshaft. If their wear insignificant, 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 forward part of the engine and measure an axial side play, laying probes between a cheek of the crankshaft and a 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 forward part of the engine, orientation shooters are turned towards a front.
5. If marking is absent, 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 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 an insert(s).
