CAMPAIGN: STARTER MOTOR PINION STOP
SUBJECT: STARTER MOTOR PINION STOP
MODEL: CERTAIN 1994 DEVILLES (4.9L ENGINE)
CONDITION
General Motors has determined that certain 1994 model DeVilles (4.9L engine) may have improperly heat treated starter motor pinion stop collars. This condition could result in a part failure causing slow engine crank speeds or an engine no start condition.
DEALER ACTION
To prevent the failure from occurring, dealers are to inspect and, if necessary, repair certain starter motors on all affected vehicles as per the Service Procedure section of this bulletin. Starter motors with date codes of N093, N103, N113, N123, N133, N153 and N163 are to be repaired by replacing the pinion stop collar and retaining ring. No repairs are necessary on motors that fall outside of these date codes.
VEHICLES INVOLVED
All 1994 model DeVilles (4.9L engine) within the following VIN range require this campaign: From RU223740 Through and Including RU231486
All vehicles indicated on your Dealer List require this campaign; other suspect vehicles should be checked for campaign involvement prior to sale or service utilizing the Vehicle Information Service System (VISS).
DEALER LIST
A list of involved vehicles, which our records indicate were sold by or shipped to you, is enclosed for your follow-up. This list contains owner names, addresses and telephone numbers obtained from Cadillac delivery records. Dealers are to contact the owners of the vehicles indicated on their list and arrange for the campaign correction to be performed as soon as possible. If no list is enclosed, none of the involved vehicles are known to be in your area at this time.
DEALER CAMPAIGN RESPONSIBILITY
All unsold new vehicles in dealers' possession and subject to this campaign must be held and inspected/repaired per the service procedure of this campaign bulletin before owners take possession of these vehicles.
Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time forward.
Owners of vehicles recently sold from your new vehicle inventory are to be contacted by the dealer, and arrangements made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such owners a copy of the owner letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the owner may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.
COURTESY TRANSPORTATION
The availability of courtesy transportation to owners of vehicles involved in this campaign is of the utmost importance in maintaining customer satisfaction. Dealers are to take the steps necessary to ensure that these owners clearly understand that courtesy transportation is available and will be provided upon request at no charge to the owner.
To support dealer efforts in this regard, Cadillac has made specific adjustments to allow payment of courtesy transportation claims related to the completion of this campaign even though the labor time involved is less than two (2) hours. Dealers should submit such claims in the normal manner and appropriate credit will be issued.

SERVICE PROCEDURE
*** INSPECTION ***
1. All vehicles within the VIN range should be inspected to determine the starter motor date codes. The date codes are imprinted on the upper half of a tag located on the motor end of the starter. The tag information is read upside down as viewed from the bottom.
2. Vehicles should be inspected by raising the vehicle on a hoist and utilizing a mirror and a flashlight to read the date code in the mirror from below the vehicle. It is also acceptable to use a pliable material such as modeling clay or similar material to make an impression of the date code and then reading the impression in the mirror.
3. Starter motors with date codes of N093, N103, N113, N123, N133, N153 and N163 are to be repaired by replacing the pinion stop collar and retaining ring. Proceed to Step 5.
4. No repairs are necessary on starter motors that do not match the date codes indicated in Step 3. Proceed to Step 17.
