Bosch 11247 Rotary Hammer would not hammer.
Removed top frame piece and extracted all old oil. Removed front circle lock rings holding the nose of the hammer drill on, then removed large snap ring and removed cylinder and all gears and seals. Please note: if you're going to attempt this make damn sure you TAKE PICTURES!!! of each step of the process because you will never remember the sequence of reassembly or the position (front/rear) of the gears, shifter, and shims. Do NOT rely on any of the parts breakdown pictures available on the internet, they are fascicle and incomplete. Once I replaced all seals and put in new oil (I used refrigerant oil instead of the Bosch brand) and reassembled the drill, it worked like brand new. Parts were exactly as ordered and a perfect fit, and shipping was quick. Thank you for the great service.
