How do you rotate the flywheel on a 1986 F-150 to get the starter to engage I want drive it to the repair shop.?

You Can Rotate The Engine By Turning The Harmonic Balancer, ( Crankshaft Pully Mounts On It ) By Using A Socket And Extension That Fits The Nut Holding The Balancer On It Will Be Rather Large Maybe 1 &1/2 Inch Or More. You Can (maybe hold the fan belt tight enough & turn the engine this way. Before I Did All This I Would Make Sure Its The Ring Gear & Not The Starter Drive. Good Luck
