- First, use a 17-mm socket or open-end wrench to remove the retaining nut from the fog lamp-mounting stud. Be careful to catch the lock-washer that’s under the nut as you remove it. Then lift the lamp up so the mounting stud clears the mounting hole, and pull the fog-lamp assembly out from behind the bumper.
- Remove the screw from either side of the assembly, and then pull the assembly apart. Remove the halves of the housing from the reflector.
- Unplug the single connector for the lamp on the back of the reflector. The lamp is held in place by two small springs retained in notches. Push them toward the reflector and then pry slightly outward to release from the notches. Rotate them on their hinges away from the back of the lamp.
- Pull the lamp assembly out the back of the fog lamp.
- Insert a new lamp assembly. Note that because the lamp is directional, there are two differently shaped cuts in the base. It must be installed in the right direction so the cuts match properly with the corresponding male parts in the fog lamp assembly.
- Relock the two retaining springs in the notches on the reflector.
- Reconnect the electrical connector securely by inserting it over the connector prong on the back of the assembly.
- Check the rubber gasket on the outside of the reflector to make sure it is intact and not cracked. If it is torn or damaged, replace it.
- Install the front and rear covers over the reflector assembly. Squeeze the halves of the covers together so the holes line up, and then install the screws on either side and tighten them gently.
- Position the mounting stud through the mounting hole on the bracket behind the bumper. Install the lock-washer and mounting nut.
- Turn the lamp until it is aligned straight with the bumper, and hold it while tightening the nut.
These instructions should help you do most routine light bulb or sealed beam replacements on your tractor. Although every truck is different, many share common lamp designs that come from the same suppliers. Consult your owner’s manual for specific information relating to your vehicle, which may differ slightly from what’s above.
