This is extremely useful if the gearbox on your drill is damage... ... i was using my dewalt hammer drill in the drill mode and suddenly got slower i though the battery was running out. as i ...Looking forward to the repair video.

Try turning the ring to 2 or 3 and run the drill holding the chuck so the clutch slips then try turning it to drill setting. Also try to do it in different speed settings. If not it sounds like a fault in the gear module. It might just be a metal clip just under the clip in side. Undo the 4 screws holding the gearbox onto the housing and carefully remove it, you might see the fault or loads of dirt that needs cleaning. Go to http://www.2helpu.com/world/map.aspx for a drawing.

I am assuming you are talking about not being able to move the "Mode Control Collar" and unless you can get it out of hammer mode, you will not be able to change the torque collar either.

If you feel comfortable taking it apart AND its no longer under warranty, my best guess without seeing the tool will be part# N026313 Gear Case Assembly. It costs about $80.00 US

Hopefully its under warranty, if so you can go to

Good luck

Sorry I wasn

Did you try oil or other type of lubrication under the bezel? Hammer drills make a lot of dust.

Check the speed selector switch. if it is not fully engaged (usually because of dirt) the gears will slip. cycle the switch a few times.

The brushes might need to be replaced. You can find them on Ebay and are easily to replace.

Hello. I can help you. Your motor is producing the smoke. Before more damage is done I recommend taking it or sending it to a Dewalt sercive center.

i am guessing the transmission problem not enough tension to the clutch

ya its a chuck problem wont hold in reverse

chuck should be replaced to parts # 33007575 newer style.
