  1. Ridgid R86034 Trigger Assembly Replacement, Disassembling Ridgid R86034 Housing: step 1, image 1 of 1
    • Use the flat side of a metal spudger to peel the black rubber cover off of the casing.

    • Use some force; the rubber cover is securely attached to the housing.

    • Rotate the casing until it fits onto the housing with no gaps between it and the clear cover.

    • Orientation is important when putting the rubber cover on the casing.

    • Remove the plastic cover with your hands.

    • There is no need to force off the plastic cover. The plastic cover should be much easier to remove than the rubber cover.

    • Unscrew the four 16 mm long screws from the back panel with a T10 Torx Screwdriver.

    • Use a firm grip to peel off the back panel. It is sealed tight and requires a good amount of force to remove.

  4. Ridgid R86034 Trigger Assembly Replacement: step 4, image 1 of 2 Ridgid R86034 Trigger Assembly Replacement: step 4, image 2 of 2
    • Unscrew the eight 15 mm T10 Torx screws from the housing

    • The screw hole located nearest the battery port is deep and small. Most screwdrivers with replaceable bits will not fit into the hole. Instead, use a conventional screwdriver that fits.

  5. Ridgid R86034 Trigger Assembly Replacement: step 5, image 1 of 1
    • Place the driver flat on a table before completely separating the two halves of the housing so components of the drill don't fall out during opening.

    • Pry apart the two halves of the housing at the back side of the driver using the metal spudger.

    • The housing is easier to remove if you pry from multiple sides.

    • Do not remove the direction switch.

    • Pull out all electrical components from housing by hand.

    • Lift out the motor.

    • Follow the wires.

    • The components should come out of their respective slots with ease and require little force to lift out.

    • The circuit board located nearest the battery pack and the LED light will be hard to pull out.

    • Remember to precisely place all components in their correct slots with their correct orientations when reassembling.

    • DO NOT attempt to desolder the white shrink wrapped wire located at the bottom left of the trigger assembly. It requires advanced soldering techniques and isn't necessary.

    • The soldering iron is hot and could burn you.

    • Take note of where each wire is attached to the trigger assembly for resoldering the new trigger.

    • Use the soldering iron to desolder and remove the red, blue, and three black wires.

    • If you don't know how to desolder, or need to brush up on your skills, iFixit posted a How To Solder and Desolder Connections guide.

    • Use the wire cutters to cut the white wire, as close to the terminal on the trigger assembly as possible.

  9. Ridgid R86034 Trigger Assembly Replacement: step 9, image 1 of 2 Ridgid R86034 Trigger Assembly Replacement: step 9, image 2 of 2
    • The following steps are for your new trigger assembly.

    • Be careful not to cut the wire while stripping the insulation off.

    • Using 16 gauge wire strippers, strip about one quarter inch off both the white wire of your new trigger assembly, and the white wire coming out of the translucent orange fuse.

  10. Ridgid R86034 Trigger Assembly Replacement: step 10, image 1 of 2 Ridgid R86034 Trigger Assembly Replacement: step 10, image 2 of 2
    • The soldering iron is hot and could burn you.

    • Solder the red, blue, and three black wires to their respective spots on the new trigger assembly.

    • Be sure to attach each wire to the same location on the new trigger assembly as it had been on the old the one.

  11. Ridgid R86034 Trigger Assembly Replacement: step 11, image 1 of 1
    • The soldering iron is hot and could burn you.

    • Solder the two loose ends of the white wires together.

    • Wrap the joint with electrical tape, to ensure that the circuit doesn't short.
