I just changed the chuck on my 18 volt xrp half inch hammer drill,yes first you must remove the torx screw with #15 torx bit,note this is a left handed thread screw,knowing the bad chuck was bad I added some heat from a propane torch to the chuck then making sure it was in 1st gear i took some vise grips and the chuck is screwed on with normal right handed threads,it broke loose (was stubborn but needs a lot of torque )ahhhhhh wat a pain.

ya its a chuck problem wont hold in reverse

the problem is the metal part of the clutch that meets the pin from the transmission. remove the 4 screw from the clutch & check if the the inside of the clutch & the trans pin meets. all you can do is to push back the metal parts of the clutch setting.
