How to Replace the Housing Set on a Makita Cordless Hammer Drill (Model LXPH01)

Drill housing hammered? It's time to face the fix. Whether you are a master carpenter or an occasional drill-seeker, eReplacementParts.com provides the parts, procedures and facts you need to fearlessly fix what fails you.

The housing set is the most visible part of your cordless drill, and it serves several functions. The housings secure the motor, brush card, gear box and clutch assemblies. The central part of the housing forms the drill's handle and secures the switch. The lower portion of the housing is where the battery mounts and locks into place.

The housing set is usually replaced due to damage caused by accidentally dropping the drill. Overheating the motor (or switch) can also damage the housing by melting portions of it.

This article provides step-by-step instructions for removing and installing the housing set on a Makita cordless hammer drill.

Let's get started.   REMOVING THE HOUSING SET [top] 1. Remove the battery.

Remove the battery from the drill.

  2. Remove the rear cover.

Remove the (2) screws.

Remove the rear cover from the drill.

  3. Split the housings.

Remove the screws from the top half of the housing.

Lift the top half of the housing away from the unit.

  4. Remove the primary components.

Lift the heat sink out of the housing.

Lift the terminal block out of the housing.

Carefully lift (as a single unit) the motor, gear assembly, heat sink, terminal, and switch assembly away from the bottom half of the housing.

  5. Remove the secondary components.

Slide the leaf spring out of the lower half of the housing.

Slide the F/R change lever out of the lower half of the housing.

Remove the screw securing the belt clip to the housing.

Remove the belt clip from the housing.

  INSTALLING THE NEW HOUSING SET [top] 6. Install the secondary components.

Install the belt clip onto the new housing.

Secure the belt clip with the screw.

Install the leaf spring into the new housing.

  7. Install the primary components.

Place the motor, gear assembly, heat sink, terminal, and switch assembly in their approximate position within the new housing.

  8. Seat the motor and gear assembly.

The notch on the yoke unit is designed to engage the plastic tab on the lower half of the new housing. Rotate the yoke unit (as necessary) to ensure alignment of these components.

Manipulate the motor and gear assembly (as necessary) until: 1) the notch on the yoke unit engages the tab on the housing; 2) the speed-selector switch is properly seated within the channels on the housing; and 3) the brush card is properly seated in the housing.

  9. Install the LED.

Install the LED assembly into the housing; the wires for the LED light should pass beneath the switch assembly.

Tuck the wire connector clip for the LED into the recess in the housing.

  10. Seat the switch.

Align the notch on the forward/reverse change lever with the post on the switch.

Install the switch (and F/R change lever) into the lower half of the new housing.

Tuck the switch wires into the channels on the housing.

  11. Install the heat sink.

Install the heat-sink into the slot on the new housing.

Verify that the wires (extending from the heat-sink) are positioned on the switch-side of the plastic post (not on the motor-side).

  12. Install the terminal block.

Slide the terminal assembly into the new housing.

Tuck the switch wires (connecting the switch to the terminal) into the center channel of the new housing.

  REASSEMBLING THE UNIT [top] 13. Reinstall the top half of the housing.

Inspect all of the wires for potential pinch-points; make adjustments as necessary.

Install the top half of the new housing.

Secure the top half of the housing with the screws. Note: Because this is a new housing, the mounting holes (on the lower half) do not yet contain threads. Therefore, it is advisable to use a hand-screwdriver (instead of an impact driver) to initially install (tap) the screws into the mounting holes, and create (cut) the new threads. Subsequent removal and installation of the mounting screws may be completed with an impact driver (once the threads have been cut).

        14. Reinstall the rear cover.

Install the rear cover.

Secure the rear cover with the (2) screws.

  15. Reinstall the battery.

Install the battery.
