Makita Drill Repair – Replacing the Switch (Makita Part # 650747-2)


“The variable speed switch in your cordless
tool performs a couple of functions. First, it allows you to turn the tool on and
off and adjust the motor speed. Second, it allows you to change the direction
the motor rotates. Over time, the switch can wear out. Either not turning on or losing its ability
to vary the speed of the motor. Replacing the variable speed switch is a repair
that you can do yourself, and I’m going to show you how. Hi, I’m Mark Sodja. Do it yourself repairs like these are easier
than you might think. From lawn machines to cordless drills, kitchen
mixers, outdoor grills, our how-to videos walk you through each repair from start to
finish, so doing it yourself means never having to do it alone. Let’s get started. I’ll begin by removing the rear cover from
the housing. Now, remove one half of the housing. There’s a label between the two sides of the
housing. I’ll cut that label with a knife. Now, I can separate the two halves. With the housing removed, now I have access
to the switch and all of its wiring. I’ll begin disconnecting the wiring. I’ll pull the connector out for the LED light
and disconnect it. Now, I’ll pull out the battery connector. I’ll take note of the location of each of
the wires and then disconnect them. Lift the switch away from the housing. Again, note the location of the wires and
remove them. Now, begin installing the new switch. First, you need to transfer the heatsink from
the old switch to the new. It’s held in place with a screw. Reconnect the wires. The red wire from the brushes connects to
the M1 connector. The black brush wire to M2. The black battery wire goes to the negative
terminal. The yellow wire in the center, and the red
wire to the positive connector. I’ll realign the battery connector with the
housing and slide it in place. I’ll align the switch with the housing, as
well as the heatsink. I’ll tuck the wires down into the housing
and reconnect the connector for the LED light, and tuck the connector down into the housing. Now, I’ll reinstall the housing and secure
it with the screws. I’ll finish up by reinstalling the rear cover. That’s how you can replace the switch in your
cordless drill. Be sure to check back often for new videos
