hi , I have a a10 1959 , the end float is 15 thou, can I still ride it or is it too far gone, will it do a lot of damage , it is a strip down of the engine I would like to avoid this as I am only a sunday morning rider your thoughts on this will be very welcome , thanks P P
BSA Service Sheet 208 states that it should be on A10 Maximum float should be .005 in. Any error should be corrected with additional packing shims. Commando has more knowledge than I do, I'm just going by the book.
Hi Check the sump plate filter for any shim debris, if there is any then the engine needs attention immediately There are dozens of similar topics on the A10 forum Excess endfloat is usually caused by the cush drive nut not being properly torqued up allowing movement between the crank and main bearing inner race, this chews up the shims wears the crank mainshaft and the drive splines On one occasion I saw a rod failure due to excess endfloat, but this was a severe case
