Crank shaft pulley wheel came lose , but it wasn't the bolt . It was stripped down and found to be from inside the sensor blade , had been worn away , and so had the round big washer
All new parts were bought and when being put back together , it was found that the wood ruff key when fitted was not a tight fit, and loose , any it was put back to gether, and worked grand for 3 weeks , but nowthesame has happened again ,
1. Should the woodruff key be a tight fit ,theres more than likely enough room for two in the crank slot
2. Or is it a new crankshaft ( God forbid)
Any help please lad
