Then came the chamber (bottom bracket) to the series. With a crank I removed the crank on the left and the 5-speed crank along with sprockets on the right. It took some strength, the crank of the square shaft of the cartridge chamber to get. Now I was curious if the stock turn out the lies, after all, it was now over several days have been sprayed with penetrating oil. With the right bottom bracket key, I tried to solve the camp, but the thing was rock solid and yielded no tenths. With violence and greater leverage to work I did not want to the thread in the bottom bracket is not damaged, I hoped that I turned in the right direction. I go like this one from the BSA-thread 1.37 "x 24 with right hand thread on the left and right hand thread is installed. After the next day I again tried my luck, the camp was moving but I chose another solution.
I borrowed from a hot plate, the heat usually thought of ball bearings for is getting better at it on a wave. I asked but the complete bike with the bottom bracket to the plate and the chamber heated to about 75 degrees (measured in square).
Then I sprayed a warehouse with the internal teeth of the cold spray and immediately proceeded to the BB key and ... the camp was moving. Now I could not quite turn out and clean the bottom bracket. 
following chamber came to light: Shimano BB-LP20
thread with BSA (1.37 x24), 68 mm case width 110mm axle length.
then I ordered a BB-UN54 with the same information.
Next, I cut the gears and all cleaned. The pedals I have left once on the cranks, but even they get a load of new fat.
The rear Cantilerverbremse I also completely disassembled and cleaned.
Now I have only one lying around enough items that I only can once Reassemble magazine and the new chain are ordered and on my last stroll through a bike shop I have to say two pair took new brake pads, if go whole hog, eh ;-)
The waiting time for the camp bridging I with some reminders:
