[QUOTE="oexing, post: 136109, member: 1493"] Problem with these bolts seems same like with brake drum bolts on hubs, or sprockets on hubs. You want ZERO play in the bolt fits in bores so all load will spread evenly onto all bolts . Great job with precision ground bolt shafts and reamed bores but the cruel reality is you will not get all fits so perfect for even loads on all bolts. And still some play in threads too, these are not meant to bear side loads. One good way would be to replace all bolts and nuts with rivets , possibly aviation ht alu rivets that you heat up to 550 degrees to anneal them before riveting. Rivets will take the complete space within matching bores and will be evenly loaded afterwards. You don´t have to disassemble that kind of parts all the time I guess when there is no need. And even so, you can drill out alu rivets no problem, they do it all the time on aircraft for repairs. I will use alu rivets on brake drums and sprockets but you can keep your bolts provided you put a good measure of mild to medium Loctite on bolt threads plus the bolt shafts to fill any gaps in the assembly. It is NOT a matter of preventing shaking loose the bolts but to fill up all space within the fasteners to spread all loads safely on all bolts. So really this will save you any problems described above. Easy to do with existing spares, you cannot do any harm but don´t use high strength Loctite, even mild types are allright as they can carry high loads from shear forces. Vic [/QUOTE]
