Hi, what i found out was that my TBs have no locknuts on the inner side (pulleys). To assemble the TB, I need a locknut which screwes on the new shaft (spindle). Unfortunately those are not included in the kit.
BTW, if you look really close at the picture in the first post of this thread (I think it is a picture of 1150 TB), you can see, that there is no locknut to keep the pulley on the shaft...
