Replacing the Bearing Flange Question by Valerio 08/13/2009
Hello does someone know how to change the bearing flange for the 11236VS. When i am trying to insert the new bearing flange it goes in but it sticks out nearly 2 millimeters en when i attach the screws it does not going in all the way. When i turn the armature fan to see if the bearing flange is inserted correctly i see that it does not turn so the bearing flange is not going in correctly.Can someone help me please

My drill is running very slow aned i think is making too much effort and after a few seconds it smells like its burning i changed the carbons and wiped some dirt of the field and nothing happened.
Someone gave me a Bosch 11236VS hammer drill that has lost its hammering ability. This unit has seen lots of hard pro use. Looking at the exploded diagrams, my guess is that its general means of function is that the "arm" on the "eccentric" pulls the piston rearward, compressing the main spring (pulling from the front of the spring thru linkage coming through the spring from the rear), and at a certain point in the rotation of the assembly, the piston is released, striking the rear of the striker pin, which is linked to the chuck holding the bit. The only other mechanism I can imagine is that the "eccentric arm" merely plunges the piston forward against the rear of the spring (and thru linkage to the chuck), but it seems to me that this would supply an insufficient force for the impact function. I have disassembled the unit (quite a greasy mess), and can see no broken or obviously worn parts. I could NOT see some of the forward parts which, if my memory serves me correctly -- it's been perhaps a year -- were hidden inside the impact mechanism housing, which seemed a more formidable task than I was ready to tackle without knowing more. Anyone know what part or parts are worn o...

I bought a new Bosch 11236VS hammer drill on a clearance rack at Home Depot. It does not have a chuck but the price was $60. so I figure I can afford a new chuck at that price. My question is since I don't have an old chuck to take off, is there any trick I need to know to install the chuck? Is this a snap ring and ball? And no I don't feel guilty about the price I paid....

I just acquired a second one of these and it seems to have slightly more "gear" noise than the first one. The motor brushes are worn much less than 50%. So, if they haven't been replaced, this drill should have a good bit of life left in it. I noticed an excessive amount of grease at the rear of the chuck and in the area of the drill/hammer selector knob. After cleaning everything externally, I removed the rear handle/cover and the bearing flange so that I could check the grease inside the drill. It looked sort of like the greasy residue that I've sometimes seen in drains - Dark and almost soupy. Is this normal? If not, what does the color/consistency indicate?
What is the proper grease to use in these drills? Should it be packed full or not?
Other than improper lubrication, what is the most likely cause of the additional noise I am hearing? (I understand that there are dozens of parts but what are the most common issues?)
I have tested the drill and it seems to function normally. I did not run it for more than about five minutes so I don't know if the grease on the exterior came from sloppy lubing of the bits or if it is leaking through the shaft or knob seals. Are such l...
