4.11. Removal of a bent shaft


The bent shaft can be removed only from the engine removed from the car. It is also previously necessary to remove a flywheel, a quencher of tortional fluctuations, a gear belt, the oil pallet, an oil receiver pipe with the mesh filter, the oil pump, pistons and rods, and a back cover of a bent shaft.

1. Before removal of a bent shaft measure its axial side play with use of the indicator of hour type.
2. Move a bent shaft back against the stop and install the indicator of hour type on 0. Then move a bent shaft forward against the stop and write down indications of the indicator. If the axial side play is more than admissible, check the surfaces of a bent shaft adjacent to persistent half rings, for wear. If wear is not recorded, replace only persistent half rings.
3. Measurement of an axial side play of a bent shaft can also be performed with use of edges of the probe.
4. Mark covers of radical bearings.
5. Gradually and consistently unscrew bolts of fastening of covers of radical bearings. On the engine 3VZ-FE V6 of a cover of radical bearings are executed as the uniform block. On the engine 1MZ-FE V6 bolts of fastening of the block of covers of radical bearings are established the block on each side.
6. Remove a bent shaft from the block of cylinders of the engine.
