Question about Makita 18V LXT Lithium - Ion Cordless Impact Driver Kit Model BTD140

The motor is working but the chuck head is not turning properly - it turns and then when you put pressure on it it stops. I have 3 makita drills and this is happening with all of them

    Makita 8444D

  • david549 Apr 20, 2009

    I have a 8444 combi and when pressure is put on to drill it seems to disengage, the motor is still working but the chuck can be stopped with light hand pressure. All switches are engaged correctly.

    Only had light use and quite frankly this is very poor reliability.

    This model wouldn't last 1 day in the pro field.

    Regards, David

First, check the lever on the top of the drill (high/ low lever speed) and make sure it is engaged in one of the positions. If it is in the middle it will cause your drill to stop. Otherwise, the gear box is gone and will need to replaced. The part # you need is #125-429-0 and it runs about $59.20.
Good luck

Makita bhp453 chuck screw wont loosen


The chuck screw on drills is put in with lok-tite and is reverse threaded. You need to get the screwdriver on it firmly and turn it clockwise, as you are, with strong, constant pressure until it breaks free. Don't let the screwdriver slide out of the screw slot, if you round off the screw head you'll have to cut the chuck off. If it still won't break free, try putting the drill in a vice or use a screwdriver with a hex nut molded into the driver shaft so you can use a wrench for some more torque.

I have just purchased a Makita 8391DWPETK 18V Cordless Combi Drill - how do i actually put a drill bit in? Do I need to take off the plastic ring?


The large black part of the chuck should turn left and right to extend (close) and retract (open) the three chuck teeth that hold the bit in place. Turn the chuck to open it far enough to get your bit fully in the chuck then turn it closed to hold the bit in. When the teeth make contact turn the chuck a bit further to get it tight enough that the bit won't slip. When you get used to it, sometimes it's easier to hold the chuck lightly and turn it by lightly squeezing the trigger to turn the chuck with the drill motor.

How do i remove the chuck from a Makita 8391D


I think you will find that if you open the chuck fully you will see a cross head screw inside the chuck which you need to undo before removing the chuck. this secure the chuck from unscrewing while being used in reverse to undo screws. Once this screw is out a spanner is used at the base of the chuck to unscrew it from the shaft. this may need a short sharpe shock to get it to move.

Makita 6408 drill motor. can't see how to replace the chuck.


If you have the 6408 as listed the spindle is threaded and you are correct there is no retaining screw. What you would need to do is find a bent handle allen wrench about the size of the chuck capacity 3/8" and insert the shorter end in the chuck and tighten. put the chuck on a block of wood or workbench and position the long end at about a 30 degree angle in the counter clockwise position and strike it with a hammer, this might take a couple hits. If this is not a 6408 let me know and I will look at the tool for you and see what you got.

Can't get the keyless chuck off cordless Makita 6095D drill.


If this is a newer tool it is probably a Torx drive screw usually a T20. The screw is LH thread and after removing it you will need to put some screws back in tool to remove the chuck. First shift the gear selector to the low setting and the clutch to the drill only. Next get a bent handle allen wrench about the capacity of the chuck install the short end of wrench in chuck and tighten. Put the chuck on a block or wood or a workbench to support is and turn the wrench to about a 30 degree angle in the counterclockwise position. The chuck has standard threads so you want to hit the wrench with a hammer to loosen it. This might take a few tries but it will work. Good luck
