This drill is compact, powerfull and easy to use but all these drills have a defect, the gear on the armature can't take the tork, this is the first part to go bad in this unit, I have 4 units in my shop with this problem, the rest of the unit is fine but I would have to replace the armature in all 4 units , I feel this a warrenty problem and i'm not sure if I will purchase any of these units in the future. With this type of problem I will go to a different Brand.
I have a Bosch 11224VSR Hammer Drill that leaks oil out from around the chuck. What do I need for parts. The drill has very low hours and work well other than the leak...

I own a Bosch Bulldog 11224VSR rotary hammer that has very weak blows. I opened it and a quick inspection tells me the the general mechanichal is excellent for a machine that has worked A LOT.
But i also saw that the striker that travels inside the striker piston was quite deep inside the piston (which is in fact a cylinder). I took out the striker and then put it back inside the cylinder so the green O-ring was just passed the side vent hole in the cylinder. I then pushed it hard to check the air tightness and SURPRISE ! I HEARD A FAST AIR LEAK (PFFFT !). I removed the striker and inspected the cylinder's inside to see a circular groove machined in the cylinder. So, if i push the striker far enough to allow the O-ring to access this groove, i lose all my air pressure.
My questions:
1 - Where is the stryker supposed to be in the cylinder ? In front of the
machined groove or behind it ?
2 - If it's behind the groove what does cause my problem ? I inspected both the striker
and the striker pin and i found no signs of wear, no chips, no cracks.
I have a Bosch 11224vsr hammer drill that has a broken chuck. The SDS bits will not lock in or turn when the motor is engaged. I have not been able to figure out how to take the chuck apart so I can see what is wrong. Does anyone know how to disassemble this drill?...

Does anyone know the correct oil or grease for this hammer drill? I've used this tool extensively and now, when it heats up, the grease or oil is dripping down the tool into my work. I'm sure the seal is probably defective as well, but want to make sure the tool has enough lubrication.
Anyone? Many thanks.
