My pulley from the crankshaft came off, it might be a stupid question, but did it break or just come off?? 1999 Mercury Grand Marquis

Not a stupid question. If thedampener is not tightened down sufficietly., The bolt can work itself out over tine.Without the clamping effect of the bolt the hub is able or will react to the crank shaft rotation pulses.which the dampener is supposed to absorb. Enough vibration,rotation counterin stress and eventually shears the keyin the crank and the dampener hub starts slipping on the crank . The rest is a given, the more it moves the more it loosens untilit no longer holds, Then you end up ssking this question. If you have lost a dampener, Just installing a new one will more than likely be futile.. The crank is now worn down and there will not be adequate sizing for the interference fit.. If you clean up the crank, and use loctite red on the pully and crank surfaces making sure the bolt is tightened real good with loctite thread lock on the threads, you mjust might get away with it. I can't see the dmage so you make the call. Now is you chance to replace the front crank seal. Is it in the shop now?

Remove bolt on crank ram 1500 360 engine 1995

The bolt holding the pully on the crankshaft is normal thread, so you turn it CCW to remove.
But you will need someone to lock the crankshaft from turning, by putting a bar into the flywheel teeth. If there is no opening, you can make one by taking out the starter.

How to remove bottom pully bolt 1.6 hdi 307

you need to peg the crankshaft near your gearbox. There is a hole in engine block for this purpose. Find this hole and insert an allen key (thick enough to fit in there). Turn the crank pully with ratchet in clockwise while try to find out the locking hole in crankshaft near gearbox by pushing allen key through engine block hole. You'll hear a click and the allen key goes fully inside. Now your crankshaft is locked and you can open (anticlockwise) the pully bolt.

Is the bolt on the crankshaft pully right or left hand threads?

The crank pulley bolt on most Honda engines are very difficult to loosen. Most 1/2" impact guns are just are not strong enough to loosen them. The choice is yours to either use a 3/4" impact gun, the bolt is left losey, righty tighte

They are usually in there pretty tight. If drivable, you can have someone loosen it up with a shop air gun.
Thread is not reverse.
There is a second way to remove it...Use a solid 1/2" breaker bar with the correct size impact socket. You need to support it and brace it against the floor. Then "bump" the engine over Don't crank, just bump. The engine crank will unscrew itself from the bolt. Be careful doing this if socket and bar get loose they can damage you and stuff around the area where you're working. I use a pipe driven into the ground with a pair of vise grips attached to the breaker bar to keep it at the right height. (bar goes inside the end of the pipe)

The large bolt holds on the lower crankshaft pulley for timing belt, the six small bolts hold the larger pulley that drive the alternator, power steering etc. It sounds correct.
