I tried searching but I can seem to find any info on what you guys use to lock your crankshaft when torquing up the bottom pulley bolt, I know that Vaux and sealey do a tool but its a bit dear for a one off job. I have had the pulley off before to do the chain kit but the bottom seal is leaking again so I suspect the pulley is worn, when I tightened it last time I think I used a bar and somehow locked it, it worked but I remember it being a precarious so I want to do it properly this time. What do you suggest? thanks
