[QUOTE="oexing, post: 101054, member: 1493"] Greg, why did you choose steel sleeves ? I know Yam SR and XT have cast iron sleeves for the crank main ball bearings but don´t know the theory behind it. I had pondered over brass sleeves but in the end I took 7075 alu sleeves for the knackered HRD bearings resp. the metric alternatives in my projects, just to have same conditions as standard but certainly with my calculated shrink fits. So I know how to use heat with ease to fit and disassemble when pairing an alu case with steel components like bearings. With a correct fit in the beginning alu cases should last ages - at least longer than my expected life span . . . Vic [/QUOTE]
