Makita impact driver wobble

What parts should I consider replacing to fix a drive wobble on my impact. it's not the bit holder, and it's at the point where a 3" screw is difficult to drive without stripping.

Many of my customers that use this tool heavily have the same problem. It's usually the Hammer Case (PN 154590-6). The nose if the case is the bushing that holds the anvil in place and sometimes wears out of round. Rarely the anvil (PN 324432-0) wears where it passes through the hammer case so check that also.

SOURCE: Makita 14.4V Cordless Impact Driver only works at high speed

Most cordless drill / drivers like this have electronic switchs which unfortunately would have to be fixed by a repair agent. Depending on it's age - make sure that you tell the agent that it never really worked properly, warrentys only cover parts that were faulty from manufacture and not wear and tear, so it may get fixed for free depending on the repair centre

Place drill in vice with chuck in vice facing up . Clamp chuck lightly but with enough force to hold firmly.
put allen wrench in chuck and lightly tap down to make good fit to allen screw head.Clamp chuck jaws down onto allen wrench lightly to hold wrench steady. Take piece of pipe to end of wrench,10".
These chuck screws are tight. Hammer clockwise until screw brakes loose.Open chuck completely and remove screw.Chuck is threaded to spindle shaft . Place allen wrench with long end facing out of tool in chuck and tighten chuck securely. With hammer tap allen wrench sharply counter clockwise ( normal thread.)

I would recommend going to Makitatools.com and typing in your model number for a schematic. Basically all you have to do is remove the 4 screws on the front holding the gearcase and then remove all the other screws holding the handle halves together. Let me know if I can help

Screw driver bit stuck in chuck of impact driver.

a tough one If can't get hold of it you may be screwed LOL
getting that rammed in the chuck is very hard to get out even if can get a grip unfortunately you can't beat it out you would do more damage And no lubricate is going to help because it was tightened down. Hope someone can help you in this otherwise may have to replace the drill

I'm looking for keyless chuck to makita btd 140

The Makita BTD140 is an impact driver that has a hex-drive anvil and bit holder assembly, it does not have a keyless chuck accessory. There are some aftermarket chucks with hex shanks on them to put into impact drivers but I've seen very few that hold up.

The chuck on the dewalt impact driver does not hold the bit holder in

If you go to dewaltservicenet.com you can enter your model number to see the parts breakdown. It can be tricky to get the retainer clip off and on but the rebuild of the bit holder is easy other than that. The spring and the steel ball are all that usually need to be repalced. Hope that helps.

Replace chuck on Makita cordless drill

The BTD 140 only has a sleve, spring, washer, clip and 2 balls. If you need to replace the bit holder then it is part of the shaft (324432-0) that comes from inside the gearbox.Cover unscrews from the body.

I have a pear 6980, and it works just high speed and you can control the speed I wanted to know what can I do if I can fix it myself

The variable speed function is controlled by the switch. On rare occasions you can remove the switch, spray it with electronics cleaner and blow it out well to get it to work again. Usually you have to replace the switch. The switch for your impact driver is Makita part number 638326-6 and runs about $65.

The screw point got stuck inside of the makita

Low quality steel drill bits get stuck in the Makita because the hammer impact squashes the metal, forming a ridge that gets snagged on the anvil's steel ball bearing. Use only impact drill bits.

Motor works,but no impact at bit

It soulds like either the striker is stuck or the ram. Unless you are mechanically inclined I would recommend taking to a repair shop. If you are give me the exact model number and I will see if they make a repair kit and get you a schematic for this tool before you start dissassembly.

Makita 6222D hole drill bit is stuck

When this happened to me I held the shaft of the drill bit tightly with my hand and reversed the direction of drive for an instant. It released at that point. It still does that occassionally though.
