SOURCE: my chuck is broke , on my 18v makita cordless

Put the chuck key on and strike it with a hammer counter clockwise. the chuck key must be properly seated in the hole. Once the chuck is brokrn free, you can unscrew it my hand. Buy a new chuck an screw it in olace and againm strike the key but no as hard clockwise. It will self tighten more as it is used, Good Luck-Ned-

SOURCE: removing chuck from Makita 64C1 drill

secure the short end of an allen wrench in the chuck, making sure it is as tight as possoble. Useing a wood or hard rubber mallet strick the long end of the allen wrench so it turns counter-clockwise. This should loosen the chuck from the spindle enough that you can unscrew it by hand.

SOURCE: Broken Makita Drill 6408k chuck

If the chuck itself slips, you can tear down the outer layers (yes it is a bit brutal)
of the chuck until you reach the inner metal core. You can then try several things;
1 loosen it with a pipe wrench, provided you can get a grip on the axle of the chuck to counter the torque
2 Weld an allen key to the metal core of the chuck and use a firm rapid blow by a hammer to rotate it counterclockwise
3 Dismantle the final shaft with the chuck core, and set it in a vise with aluminium plates to protect it, while you turn the chuck with a wrench or pliers.
4.If there is no senter lock screw inside the bottom of the chuck it may be fitted with a thread locking compound. It will loosen easilier if heated with a heat gun or moderate gas heat.Only supply just enough heat to loosen it, or the hardening of the steel may be compromised.

Fitting new gearbox to 8444d


that is a pain. when you take them out they have to go back in that specific way that specific place. if you don't get back just right the case won't fit back together. if you take it slow and only remove what you need to remove you may not have any trouble. you will have to remove all the case screws to get to the gearbox. everything is a tight fit.

Sorry Mate your battery is dead...
The makita lithium batterys dont like getting worked hard quickly.
