Hi all, I've just stripped, cleaned and reassembled one of these beasts, 1) are the pulley bolts #93/A threaded at the ends or like #933 or #3461 fully threaded? mine are fully threaded & secondly are the adjusting screws #99 chrome plated or just like the lesser plated ones, mine are chrome plated. I suspect these parts may have been replaced, but then again I could be totally wrong, afterall this item is a low milage item and overall is a very nice item. I do suspect thou that the mounting bolt is new, esp when comparing to the bottom bolt........regards wayne davidson Invers NZ.........
