SERVICE PROCEDURE (CONT'D.)

Procedure 'B' (dash-mounted ignition lock cylinders) (Cont'd.)

18. Determine the tumbler numbers and arrangement by placing the tip of the key directly over the tip of the illustrated key in section OA of the 1997 Service Manual. Be sure the key is outlined by the diagram.

Starting with position number one, determine and record the number of each tumbler in each of the nine tumbler positions.

19. Using a small, thin-bladed screwdriver, carefully pry off the spring retainer.

#### Notice: Careful pi-ying attempts, alternating from one end of the retainer to the other will result in successful removal of the retainer without tearing.

In some cases, it may be necessary to use a dental pick or similar instrument to push some of the staked ignition cylinder metal clear of the edges of the retainer to allow removal of the retainer without tearing.

20. Carefully remove the nine tumbler springs and set aside for reinstallation.

21. Remove the old tumblers and discard (only after the tumbler numbers and sequence have been determined and recorded).

22. Select the required new tumblers (Part Numbers 2852732, 33, 34, 35) and insert in their proper slots in the correct order. Pull the side bar out with your fingers so that the tumblers will drop completely into place.

23. Insert one tumbler spring above each tumbler.

24. Lubricate the tumblers with GM Part Number 12346241 Super Lube multi-purpose lubricant or equivalent.

25. Insert a new spring retainer Part Number 26047315 so that its end prongs slide into the slots at each end of the cylinder.

26. Press the retainer down. Make sure that the retainer is fully seated in the depression.

27. While holding the spring retainer in position, insert the key into the lock cylinder to check for proper tumbler installation. The side bar will drop down flush with the cylinder diameter if the tumblers are installed properly. Disassemble and reassemble if necessary.

28. Remove the key and place the lock cylinder assembly into J-41340 Lock Cylinder Staking and Holding Fixture (or other appropriate holding device).

Make sure the spring retainer is facing up and is positioned directly under the punch slots.

Push the cylinder into the lock cylinder staking and holding fixture as far as it will go. The punch slot needs to be butted up against the cylinder bezel. Secure lock cylinder in fixture.

29. Hold the flat side of the punch squarely against the face of the cylinder bezel and stake the retainer in place by staking lock cylinder metal over the retainer comers.

30. Remove the punch and rotate it 180*. Hold it squarely against the end of the punch slot and stake metal over the other end of the retainer.

31. Remove the cylinder from the holding fixture and inspect the retainer staking to make sure the deformed material is touching the retainer to secure the retainer in position. Repeat staking if necessary.

32. Lubricate the detent pins and cylinder retainer with GM Part Number 12345996 or equivalent high temperature paste type grease. Do not use a spray type grease.

Dear General Motors Customer:

General Motors of Canada Limited has decided that certain 1997 'J' and 'N' model vehicles may exhibit a condition in which the ignition key can be inserted into the ignition lock cylinder, but the cylinder will not always cycle to the "run" position.

To prevent the possibility of this condition occurring, your GM dealer will replace the tumblers in the ignition lock cylinder.

This service will be provided for you at no charge.

Please contact your GM dealer as soon as possible to arrange a service date.

If parts are required, ask your dealer for details regarding their availability. If parts are not in stock, they can be ordered before scheduling your service date.

This letter identifies your vehicle. Presentation of this letter to your dealer will assist their Service personnel in completing the necessary correction to your vehicle in the shortest possible time.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.

Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
