Removal

Details of installation of the steering mechanism


 PERFORMANCE ORDER

1. Establish a steering column in the extended situation.
2. Take liquid from the tank of the amplifier of a steering.
3. Disconnect the R-valve (Y10x1) on the left side and disconnect the conducting socket from the steering mechanism.
4. Disconnect cross-section steering draft (10) from a steering soshka.
5. Disconnect longitudinal steering draft (11) from a steering soshka.
6. Remove a heat-shielding guard (23k).
7. Unscrew returnable (30f) and forcing (30i) pipelines.
8. Remove the lock of blocking of a steering shaft. The steering wheel should not have possibility to rotate, differently the contact spring (А45) can be damaged after replacement.
9. Disconnect a steering shaft (80a) from a shaft of the steering mechanism (25).
10. Unscrew bolts (23a) and remove the steering mechanism (23).

Installation

Details of installation of the steering mechanism


 PERFORMANCE ORDER
