Hi, I found ereplacement.com's videos on assemby and disassembly of the Bosch 11224 VSR Hammer Drill.

Seems pretty easy except...

The 1st step is to remove the rubber cover and I removed the rubber cover without any diffucuties. Then the plastic sleeve is supposed to come right off. Well, on my drill it doesn't.

I've tried rotating it in case there is a keyed slot or somethnig to retain it. I've tried to pull it and pry it off but it doesn't come off. Could it be my drill is 12 years or more (Hardly used) and the sleeve is retained in some other way?

Or could it be related to the problem I need to disassemble the drill? I lent my drill out and specifically told the person several times that he needs to buy the right size HAMMER DRILL BIT and not a masonary drill bit. Well, of course he didn't listen or just saw the price of a hammer drill bit and figured no problem. Well, there is a problem now as the masonary bit is stuck. I suspect the end is mushroomed or something.

Could this stuck bit cause the plastic sleeve not to come off? I can slide the sleeve down (compress the spring) as if installing a bit. Any ideas if something is damaged inside?

Thanks
