Basically yes. Lower power units are usually titled as "hammer drills." Higher power units, usually labeled "rotary hammers," tend to be larger and provide bigger impact forces. But there are a few differences that are worth knowing: The rotary hammer usually have a chisel only feature, for light chiseling and masonry removal. Rotary hammers also have specially designed chucks that only accept bits specifically designed to fit their chuck. The special chuck on a rotary hammer helps hold the drill bit and prevents it from slipping during use.

Most of the time the o-ring on the striker needs changed. Look closely at the hammer piston as well, once in a while (very rare) the piston will develop a crack that allows air to escape by the striker, keeping it from striking the impact bolt. Make sure to add a little extra grease when going back together as well.

Sorry I couldn't be of more help. I've looked at about every DV 20 version parts list and cannot find a part 16 that would create any difficulty in removing. All are either gears, pins, or the plate that goes under the switch. from the way you are describing it it sounds like the only possibility would be the Model DV 20VB which has a spindle which has to be unscrewed from the drill chuck it is held in by a retaining clip that you would need retaining ring pliers to remove.

The speed shift slider switch wasn't lined up correctly when the unit was reassembled.
Unfortunately, you going to need to repeat the disassemble/reassemble process once more.
I've been there. It doesn't take much to be out of alignment. Set everything to the lowest setting (clutch, speed) and take your time.
