5.12. The crankshaft - dismantle

Remark.
The crankshaft can be removed only after engine dismantle from the car. Previously remove a flywheel (or a leading disk), a pulley-uspokoitel, a chain, the pallet, a maslopriyemnik, the oil pump (on V6), a forward cover and rods with pistons.

1. Previously check axial люфт the crankshaft (photo). For what 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. If axial люфт exceeds standard value, check wear of persistent surfaces of cheeks of the crankshaft. If wear insignificant, люфт has to be compensated by installation of new radical bearings. Люфт it is possible to measure щупами, laying them between an end face of the 3rd radical bearing (or the 4th on V6 engines) and a crankshaft cheek.
2. Check existence on covers of oriyentatsionny arrows and markings of number of the cylinder. Usually covers are numbered beginning from a forward part of the engine. If marking is absent, put labels with a core. Release bolts of covers on 1/4 turns at one time in the specified sequence of return (photo), until then while bolts will not begin to turn away by hand.

3. Carefully displace covers of radical bearings and remove them together with the loose leaf. On 4 - cylinder engines of a cover of back and average bearings are taken by the adaptation (photo). On V6 engines of a cover are cast in a uniform framework.
4. Carefully remove the crankshaft. Establish covers with loose leaves in a former order and tighten bolts by hand.
