How do you hold a flywheel when torquing?
Place a pry bar, pipe, or some other piece of metal between the bolt head and the ground. Turn the flywheel in the direction of engine rotation until it makes contact with your prop, and torque away!
How do I keep my crankshaft from turning?
An old trick for this is to remove a spark plug, then feed a length of string into the cylinder through the spark plug hole, leaving enough string hanging out to pull it all out when done. The string won’t compress, so stops the motor from turning, allowing you to tighten the crankshaft bolt.
Should the crankshaft turn freely?
The air conditioning compressor has a clutch on it that should spin freely as well but it will not be rotating the internals of the compressor. That you cannot rotate either cam or crankshaft pulleys by hand is completely normal. If you were able to rotate them bare handed, THEN you would have a problem.
Can you turn a crankshaft by hand?

How do I know if my crankshaft pulley is bad?
Bad Crankshaft Pulley/Harmonic Balancer Symptoms
- 1) Engine Vibrations. The first symptom that will likely come up are engine vibrations.
- 2) Alternator Failure. The crankshaft pulley is responsible for powering the alternator.
- 3) Power Steering Pump Failure.
- 4) Transmission Damage.
- 5) Irregular Idle Engine Speed.
What happens if you turn the crankshaft the wrong way?
The problem with turning the crank backwards is the risk of the timing belt jumping a tooth as the tight side of the belt is relaxed and the slack side tightened. Even if the belt does slip it will do no permanent damage, but you would have to resinstall the timing belt as per the garage instructions.
Can a engine run counter clockwise?
