Prevention
The crankshaft can be removed only after engine dismantle from the car. Previously remove a flywheel (or a leading disk), a pulley-uspokoitel, a belt (chain), the pallet, a maslopriyemnik, the oil pump, a forward cover and rods with pistons.
| PERFORMANCE ORDER |
|
|
1. Previously check axial люфт 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 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. |
| 2. If axial люфт 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 a display head люфт it is possible to measure by means of a set щупов. Carefully displace the crankshaft towards a forward part of the engine and measure axial люфт, laying щупы 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 oriyentatsionny 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, oriyentatsionny shooters are turned towards a front. |
|
5. If marking is absent, put labels with a stamp. Labels are put on inflow near a bolt head. |
|
|
| 6. Release bolts of covers on 1/4 turns at one time in sequence of return specified (at the left – 4-cylinder engines, on the right – engines 6V), until then while bolts will 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 directing pins. |
| 7. Carefully displace covers and remove them together with the loose leaf (ами). |
