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

if the drill is slipping in speed 3 & drill mode. it needs new transmission assy. see www.toolpartsdirect.com , www.ereplacementparts.com for pricing for the the parts.

see www.ereplacementparts.com or www.toolpartsdirect.com for parts & diagram.

position the drill to speed one & drill mode.u need a allen key then clamp it the chuck jaw close & tight. hit the allen key with hammer counter clockwise until its loosen. may have to do it any several times.

a higher voltage means more drilling power but it can also mean more weight - don't buy a drill you won't need, 12 volt drills are powerful enough for most home users, bigger models just weigh more so think carefully about what you will be using the drill for.

It screws off

ya its a chuck problem wont hold in reverse

you need a special jig to remove the chuck on this kind of drill

1. Turn the screw clockwise to take it out.
2. Then you needs 3/8 allen key & insert the short side of the allen key & tighten the chuck.
3. hold the drill at the edge of the table & wack the allen key
counter clockwise & do it again as needed.
4. dewalt keyless chuck will fit but you might add a washer to insure the chuck is not rubbing the clutch collar.
5. putting it back together the other way.

the charger rearly fail. it must be the battery problem.have your battery tested also the switch of the drill.if the drill runs slower than use to be changed the switch.

may not be a solution, just an idea
but the switch shits actual gears, the splines may not be aligned enough to allow the transfer.
put it back in low, run the motor a few revolutions to change the alignment of the gears, then try the shift again, like a crash box on a model T

u need allen key that fit to the chuck. insert the short end to the chuck. tighten the chuck if u can. hold the drill at the edge of the table & smack the allen key counter clockwise. do it again if needed. but before u do it set the speed to #1 position & drill mode.thanx good luck

if the battery are less than a yr old should be a warranty
if drill DC920 or DC925 they are on recall for switch. may be co'z the battery to die. have them check at ur nearest service center.

dewalt dont make 5/32 collar for the DW660. best option is to ask the guys that sales store carry woodworking stuff.sorry man

yeah you have a bad chuck. there is a screw inside the receiver of the chuck if you remove this screw the chuck will come off. Reverse this procedure to re install the new chuck.

front of the trans had a pin the spring is inside. if theres no tension maybe missing spring or the large out crown gear are worn. you can get the trans in assy,

Hi,

the Chuck should be 2 Part.

Use 2 pair of stillsons Or pipe wrenches, Tight On the 2 Chuck Parts, Crack in opposite Directions.

Alternative, Use Wrench On Chuck Jaw, Short sharp Blow With Hammer.
