I did have a crank shaft bolt come loose once on my Series 111 Safari. I was going up the Old Kent Road and heard the most horrible clattering so pulled over to investigate. A very dodgy looking white tipper lorry pulled up for the driver to ask what's up, and in a strong Irish accent when told, invited me to pull into his 'camp' (an about to be demolished Post Office workshop facility with loads of caravans corralled in it!) In no seconds flat he was under the S111 spanner on the pulley nut followed by what seemed to be a brand new Britool torque wrench
What a nice man
