CAMPAIGN:INCORRECT STEEL SPARE WHEEL
SUBJECT: INCORRECT STEEL SPARE WHEEL INSTALL NEW RIM
Models: 1993 Chevrolet/GMC G2 Vans Flint Built Only (Plant Code F)
TO: ALL GENERAL MOTORS DEALERS
General Motors of Canada Limited has determined that a defect which relates to motor vehicle safety exists in certain 1993 Chevrolet/GMC G2 vans equipped with base wheels. Some of these vehicles were built with an incorrect spare wheel. The use of the incorrect spare wheel at a regular wheel position could, under certain loading conditions, eventually cause the wheel to crack and possibly result in separation of the wheel from the vehicle. If the wheel separates from the vehicle, loss of vehicle control may occur which could result in a vehicle crash without prior warning.
To prevent this condition from occurring, involved vehicles will be inspected for the correct spare wheel and if an incorrect wheel has been installed, the wheel will be replaced.
VEHICLES INVOLVED:
Involved are certain 1993 Chevrolet/GMC G2 vans equipped with base wheels (less RPO N67/PF3) built within the following VIN breakpoints:
Year Model Plant Plant Code From Through
1993 Chev G2 Van Flint F SOP PF340171 1993 GMC G2 Van Flint F SOP PF513784

SERVICE PROCEDURE:
NOTICE: THIS CAMPAIGN DOES NOT INCLUDE RALLY OR ALUMINUM WHEELS.
INSPECTION OF THE SPARE STEEL WHEEL
1. The spare wheel will be located inside at the rear of the vehicle. The spare wheel will have a stamp code located to one side of the air valve stem as shown in Figure 1.
2. Verify the stamp code. If the stamp code is XH, the spare, wheel must be replaced.
3. Remove the spare wheel from the carrier by removing the fastener as shown in Figure 2.
4. The steel spare wheel comes from the factory painted white. The paint used is a high solid baked enamel, GM CODE WA-8624. The wheel that is received from GMSPO is painted with a primer black. The steel spare wheel MUST be painted white. If the spare wheel has been painted an alternate color, this color must be matched to the same color. It may be necessary to contact the customer if any color other than white is needed. For paint reference, refer to the paint instructions listed below.
NOTICE: When the steel spare wheel is mounted at the factory, the wheel does not have a spare tire mounted on the wheel.
IMPORTANT: It is possible that the customer has had a tire mounted to the spare wheel. The spare tire will have to be removed and mounted to the replacement wheel.
IMPORTANT: It is possible that the customer has had a flat tire or rotated the tires and has installed the spare tire to a regular wheel position. If this has happened, it will be necessary to inspect all wheels on the vehicle.
IMPORTANT: The steel spare wheel must be clean and free from all contaminants. If the wheel is not clean, poor adhesion of paint will result.
Paint can be obtained from any GM paint supplier. The paint must be an exterior Hi solid Enamel.
GM CODE: WA-8624
PRODUCT CODE: BE-1123
REMOVAL AND MOUNTING OF THE SPARE STEEL WHEEL WITH MOUNTED TIRE
1. Removal of the spare wheel from carrier is accomplished by removing the various fasteners shown in FIGURE (2).
2. Use a tire changing machine to mount or dismount tires. Follow the manufacturer's instructions. Do not use hand tools or tire irons to change a tire as they may damage the tire bead or wheel rim flanges.
3. Rim bead seats should be cleaned with a wire brush or course steel wool to remove contaminants from the bead area. Before mounting or dismounting a tire, the bead area should be cleaned and well lubricated.
4. Install the valve stem and inflate to proper air pressure, which is located on the rear edge of the driver's door. Check locking rings of the tire to make sure they show around the rim flanges on both sides of wheel.
NOTICE: It is important to note that damage to either the tire mounting surface or the wheel holes can result from the use of improper wheel attachment or tire mounting techniques. It takes 70 seconds for all the air to completely exhaust from a large tire. Failure to follow proper procedures could cause the tire changer to put enough force in the tire to bend the wheel at the mounting surface. Such damage may result in vibration and/or shimmy and under severe use lead to cracking.
CAUTION:
Do not stand over the tire when inflating. The bead may break when it snaps over the safety hump and may cause serious personal injury. Do not exceed 27S kPa (40 psi) pressure when inflating. If 275 kPa (40 psi) pressure will not seat the beads, deflate, re-lubricate, and reinflate. Over inflation may cause the bead to break and result in personal injury.
REMOVAL AND MOUNTING OF TIRE AND WHEEL IF THE SPARE TIRE HAS BEEN ROTATED TO A REGULAR POSITION -----------------------------------------------------------------------------
REMOVAL OF TIRE AND WHEEL ASSEMBLY
1. Raise the vehicle and support with safety stands.
2. Remove Hub cap if required.
3. Remove wheel nuts.
4. Remove tire and wheel assembly.
5. Remove tire from wheel by following the instructions previously mentioned for tire and steel spare wheel removal and mounting.
INSTALL TIRE AND WHEEL ASSEMBLY
1. First clean all wheel nuts, bolts, and the wheel and rotor mounting Surface.
2. Install tire and wheel assembly.
3. Tighten all wheel nuts (Qty. 5 studs). Do not torque at this time.
4. Torque wheel nuts (Qty. 5) in an even and alternating sequence to 140 N.m (100 lb. ft.).
5. Install Hub cap if required.
6. Remove support stands and lower vehicle.
IMPORTANT: Before installing the wheel, remove all contaminants on the wheel mounting surface and brake disc or drum mounting surface by scraping and wire brushing. Installing wheels with poor metal to metal contact at the mounting surfaces can cause wheel nuts to loosen. This may lead to a wheel coming off while the vehicle is moving. Possible loss of control may result in personal injury.
NOTICE: A torque wrench must be used to ensure that the rim nuts are tightened to specification. Never use lubricants or penetrating fluids on wheel studs, nuts, or mounting surfaces, as this may raise the actual torque on the nut without a proper torque reading on the torque wrench. Rim nuts, studs, and mounting surfaces must be dean and dry. Failure to follow these instructions could result in rim, nut, and/or stud damage.
BALANCING TIRES AND WHEEL
There are two types of tire and wheel balancing, static and dynamic. Static balance is an equal distribution of weight to the inboard and outboard rim flanges at one location of the, wheel. Dynamic balance is the distribution of weight on each side of the centerline so that when the assembly spins, there is no tendency of the assembly to move from side to side.
IMPORTANT: Foreign material must be cleaned from the inside of rim. Stones should be removed from the tread in order to avoid injury during spin balance. The tire should be inspected for any damage and properly balanced according to the equipment manufacturer's recommendations.
1. When balancing tire and wheel assemblies off die vehicle, use a balancer that pilots the wheel by the center hole (not wheel bolt holes) if possible. Always follow the equipment manufacturer's instructions.
2. Install Campaign Identification Label.
INSTALLATION OF CAMPAIGN IDENTIFICATION LABEL
Clean surface of radiator upper mounting panel and apply a Campaign Identification Label. Make sure the correct campaign number is inserted on the label. This will indicate that the campaign has been completed.
