[Devilish]

I have done it before, many times, last time on a M47, every time I tried to move the tensioner with the spanner, it come loose, so I wound the belt on turning the crank. Don't know why the mech would turn it opposite to its normal rotation. I always believed, the M47 chain tensioner is capable of allowing the crank to be turned in the opposite direction, otherwise the cam would chatter in normal rotation.
