my 9 speed shimano cassette fell apart so i stripped it off and rebuilt it today,the 3 screws came loose.now when its back on the ringle hub there is a small gap between the main cassette and the smallest 2 sprockets,maybe 0.5mm gap,enough to allow it all to slide side to side and enough to prevent indexing working properly..
question is,is there a small spacer missing??
