All done without any drama! You have to be very careful when you put the crank pin in, i.e. only put it in when it is almost at TDC otherwise it stops the crank in the wrong position. I can see why people struggle with the crank pulley bolt but I reckon its 40% knowledge, 40% Tools and 20% Luck. Actually had far more trouble getting it tight enough, only managed 75 deg of the final 90 deg turn and broke my snap on 18mm socket!

Serviced it while I was at it..... the top quick release clip on the fuel filter is fun isnt it.........

Thanks for the help.
