Have the spark plugs out? Pull the crank pulley, put the bolts back in and stick a breaker bar or pipe between the bolts. You can also buy a crank socket that goes over the snout of the crank and keyway if the balancer os off.
Why not just put a socket on the balancer bolt and rotate it that way? It's held on there wth a good 60-70 lb-ft/tq.
well, I tried turning that bolt but it is not moving with the plugs out, any other options? Should I worry about it, the engine will probably sit on that stand for at least another 8months, should I worry about it?
This is common practice and everybody does it including me, but "technically" this is a no-no....mostly for fear of damaging or snapping the bolt if there's too much compression and you wind up further tightening it instead of spinning the motor over.
