220.127.116.11. Check of an axial gap of a bent shaft
Check of an axial gap of a bent shaft
Axial movement of a bent shaft is limited to two persistent half rings established on both sides of the back radical bearing. From the forward party of the bearing the steel-aluminum half ring, and from the back party – ceramic-metal is established (yellow color). Half rings are made the normal thickness (2,31–2,36 mm) and increased (2,437–2,487 mm).
The axial gap between persistent half rings and persistent surfaces of a bent shaft needs to be checked as follows:
– to install the indicator on a magnetic support and to insert the ends of two screw-drivers, as shown in the drawing;
– to move a shaft with screw-drivers and to check an axial gap which has to be within 0,055–0,265 mm on the indicator.
If the gap exceeds the most admissible (0,35 mm), it is necessary to replace persistent half rings with others, increased by 0,127 mm.
The axial gap of a bent shaft can be checked also on the engine installed on the car. At the same time axial movement of a bent shaft is created by pressing and an otpuskaniye of a pedal of coupling, and the size of an axial gap is determined by movement of the forward end of a bent shaft.
