Help need ideas

My F150's nut is set at almost 200 ft lbs. Don't know the spec's to yours but its likely way up there.

There is a special tool to hold the flywheel from turning, it grabs the teeth / gear. Its in the shop manual under special tools for the power head.

That tool and a long breaker bar should remove it if you don't have an air gun with that high a capacity..

I think the F150 flywheel nut is being confused with the F90 drive sprocket nut.

You need a longer breaker bar. And be careful when the nut breaks loose. Don't ask me how I know to be careful. Now that I do.
