Removal and installation of the lock cylinder

Note: This procedure is described below using the Corsa C model as an example.

Removing

1. Remove the outer handle (see Section 19).

2. Using a screwdriver, pry and remove the circlip from the back of the lock cylinder housing (see resist. illustration).



3. Remove the lever with the leash (see illustration 20.2) and two springs, remember their installation position.

4. Insert the key into the lock cylinder and using a mandrel ∅ 2 mm knock out the cylinder pin (see illustration 20.2).

5. Turn the key anti-clockwise and remove the lock cylinder together with the outer sleeve from the body.

6. If necessary, remove the inner sleeve, balls and mounting sleeve.

Installation

7. Insert the mounting sleeve into the body of the lock cylinder, install the balls into the grooves (IN) (see resist. illustration) and thread the inner sleeve into the housing.




8. Enter the key into the lock cylinder and insert the cylinder together with the outer sleeve into the body - the protrusions of the outer sleeve must fit into the grooves on the inner (see illustration 20.7, A).
