I bought the Park Tool SPA-6 pin spanner and was almost shocked when my Fauber came apart with no problem at all. The Park Tool pins were much too small, still it worked fine after I had soaked the cup with CRC & waited for a few hours. Some parts, including the right hand bearing cup, actually unscrewed by hand. A few taps with hammer + punch were needed for the left hand bearing cup, but nothing was really that hard. The crank was full of oily sand, so taking the 30 year old Fauber apart was definitely a good idea. Recommended, but soften up with CRC or something first and get a pin spanner.
