3.10.6. Check of an axial backlash of a cranked shaft
Check of an axial backlash of a cranked shaft
Axial moving of a cranked shaft is limited by two persistent half rings established on either side of the back radical bearing. From the forward party of the bearing it is established сталеалюминевое a half ring, and from the back party – ceramic-metal (yellow colour). Half rings are made a normal thickness (2,310–2,360 mm) and increased (2,437–2,487 mm).
| PERFORMANCE ORDER
| 1. The axial backlash between persistent half rings and persistent surfaces of a cranked shaft is checked so:
– Establish the indicator on a magnetic support and insert the ends of two screw-drivers, as is shown in drawing;
– Move a shaft screw-drivers and check up on the indicator an axial backlash which should be within 0,06–0,26 mm.
|2. If the backlash exceeds as much as possible admissible 0,35 mm, replace persistent half rings with others, increased by 0,127 mm.
The axial backlash of a cranked shaft can be checked also on the engine established on the car, by means of the adaptation 67.8701.9510. Thus axial moving of a cranked shaft is created by pressing and отпусканием coupling pedals, and the size of an axial backlash is defined on moving of a forward ring of a cranked shaft.
