Question about Bosch 1199VSR 8.5 Amp 1/2 Inch Hammer Drill
Hi, I took the drill apart and found the slipping problem to be in the nose end of the drill. It's the larger gear , part # 33 (http://www.ereplacementparts.com/bosch-1199vsr-electric-drill-parts-c-128_1010_4165.html ) on the drilling spindle # 24 that the chuck screws to. It will rotate completely around the shaft, as if it was broken loose. It turns a little hard halfway around the shaft (180 degrees) then becomes very loose the rest of the way. When I spin by hand it is tight, loose, tight loose, continually.I haven't quite figured out how it comes off the shaft yet, but I'm assuming I have to remove the catch disc # 36 first. This seems to be pressed on. The other gear next to the #33 large gear, #34 locks on the shaft well when the pins #30 are engaged. I believe this would be the lower gear. It has 2speeds, 1 and 2. I never did try to see if the problem existed in low gear.
Check to make sure part number 30 is not stripped out or the edge knocked off. I can't find a part number on Ereplacement for them but I am sure that Bosch would have it. It sounds like you are on the right track and the way you describe it the gear is bad and like I said I think the keys might be bad also
