, Torx set
Parts Used
1. Remove the 4 torx screws that hold the body to the transmission housing and pull the parts directly away from each other.
2. Remove the torx screws that hold the 2 halves of the handle together leaving the body in place remove the right half of the handle. Take the clamp off the power cord so you have more wire length to work with.
3. Take note of how the wires coming from the field coil and brushes are routes through the keeper posts. Take note of the color coding of the wires going to the trigger switch.
4. Pull the brushes out of their sockets by carefully bending the holding springs back. Take note of the orientation on the wire connected to the brush.
5. Pull the coil wires out of the trigger switch. You will need to press a small round object (awl or scribe) into the small hole next to the hole that the wires are seated in to release the wires.
6. Remove the 2 torx screws on the front side of the field coil. Place the housing containing the field coil back side up on a hard surface or gently clamped into a wood vise. Use a punch and hammer gently tap the field coil out through the front of its housing. it will only need the light force for a short distance before it drops out.
7. Slide the new coil into the housing in the same orientation that the old coil was removed (wires up and towards the back).
8. Using the punch and hammer gently tap the field coil back into place. Press only on the steel housing making sure to avoid any contact with the copper wires. Re-install the two torx screws that hold the coil.
9. Route the wires as noted earlier. Pay close attention to how the coil wires exit the housing. They are in close proximity to the armature. They must have NO contact with the armature and maximum possible distance from the armature.
10. Push the coil wires into the trigger switch in the same location the old one were removed. You will need no tools, just push them in. Make sure the wires are run through the standoff posts at the back of the housing.
11. Carefully push the transmission / chuck assembly back onto the body. Secure with the 4 torx screws.
12. Put the brushes back into their holders by gently bending back the springs and sliding the brushes in, orientated as they were removed, let the spring go back into place to hold the brushes in. Re-install the power cord clamp.
13. Re-install the handle making sure the trigger switch is aligned to the cover and fits properly. Make sure to have the strain relive on the power cord in place as it may have slipped down the cord. Screw the two halves of the handle together.
14. Plug the drill in and test it. Make sure there is no unusual grinding or rubbing noise.
DONE.
