Crank bolt stuck

[Terrh]

It works like a big wheel, with a small wheel it is harder for you to get the leverage you need to move it from a standing start. There for the bigger wheel is easier to turn!
In the lowest gear you have just that, "Torque" working for you by keeping the engine from turning over in the form of gearing and compression!
If you try to bump a car in 5th it will turn over easier rather than the hard bump and kick in first!

You've got it backwards.

You want the car in 4th (or 5th, but 4th is nicer to your transmission), and then pull the ebrake or have an assistant standing on the brakes.

using 1st gives you mechanical advantage against the wheels, using 4th or 5th does not.

^thats right, it's all about the gear ratios, first gear is where the most torque goes to the wheel and the most likely of all gears for motion.

with a final drive of ~4.1 and first gear of ~3.2, each turn at the crank is then 1/(4.1x3.2) rotation at the wheel or in other words the inverse of that is translated to amplified torque

Take a minute to look over the explanation as well as the reason behind what I said and what you are posting now and you will see what I was saying!
Put a car in fifth and you can push it in gear, put it in reverse and you wont! Simple! Compression and gearing!

Just got mine off last night. Took 2 guinness, 30mm socket, a 1/2 impact gun and 180psi.

Yea man I needed a big impact gun and a big compressor

You can always get an extra compressor tank as its the cfm that draws too much air for the compressor to keep up with. Only problem is your compressor runs for a long ass time to fill it up lol.

There is no problem getting the crank bolt off when the engine is out of the car, you need to tap the crank bolt with a hammer and flat end punch to avoid missing and dsmaging the delicate front pulley.
Then a 1/2" air impact gun with as low as 80psi will open the bolt.

It is very important to re torque the bolt to factory torque. If not the pulley will be loose and as a result can fuse itself to the crankshaft,ruining a crankshaft,pulley and oil pump.

And for the record, ignore this input, he's got it backwards. Use 4th because it will put less stress on the tranny case and the e-brake and pray the clutch will hold it.

I really feel for you guys with basic hand tools, we were all there once.

Why were you removing the pulley in the first place if you don't mind me asking ?

engine blown, doing a full rebuild, needed it off before i pulled the motor so i can do the crank collar
