EXECUTIVE MECHANISM OF SYSTEM CRUISE CONTROL
Removal
PERFORMANCE ORDER |
1. The executive mechanism of system cruise control is established sideways the block of cylinders. |
2. On the majority of models for access to the executive mechanism it is necessary to remove a casing of the air filter. For further improvement of access to the executive mechanism tighten the parking brake, lift a forward part of the car and fix on supports. Unscrew screws and remove an engine mudguard. |
3. Remove a weight wire from the accumulator. Disconnect the electric socket of the executive mechanism located on a plait of wires. |
4. Using a screw-driver edge, remove draft from the spherical hinge of the executive mechanism. |
5. Unscrew the nuts, fixing an arm of the executive mechanism to the block of cylinders and remove the executive mechanism together with an arm. |
6. If necessary unscrew bolts and remove the executive mechanism from an arm. Thus note an arrangement of rubber pillows and laying. |
|
Installation
PERFORMANCE ORDER |
1. Installation is made in sequence, return to removal. At installation of the executive mechanism check a condition of rubber pillows. If necessary the length of draft can be adjusted, for what it is necessary to weaken a lock-nut and to screw or screw together spherical sharnirny connection from draft. After adjustment of length of draft tighten a lock-nut. |
