how to get the crankshaft nut out??

[talon1987]

like the title says how do you get the crankshaft nut off , what are some good methods and the motor is out of the car and on a stand

If the flywheel is still on you can wedge a screwdriver in one of the holes. Just make sure its making solid contact against something sturdy on the block. Or you can just use an impact

A impact gun, if you don't have one borrow one. If your referring to the nut on the timing belt/dampner side you'll need to turn it the nut clockwise to remove it. Flywheel bolts are counter clockwise to remove.

If all else fails, you can pull the pan and wedge a hammer between the block and a couterweight on the crank then remove the bolt using a breaker bar.

Like espinelli said if you have access to an impact gun use it, it will make things a lot easier for you. I know I tried to get that same bolt out without an impact gun and it was a total p.i.t.a.

Are you saying that its reverse threaded? I know my 6 bolt isn't and i've never heard of a 7 bolt being reverse threaded...

His statement is wrong. Both the flywheel and crank bolts have right hand threads so you will need to loosen both in a counter clockwise manner. Either he is jsut thinking of working on a perkins diesel engine or he has no hands on 4g63 experience.

Thats exactly what I was thinking.

Also for the original poster: You may want to heat up the bolt really well to get the locktite to melt.

To get that bolt out I took a stud and put it into one of the holes for the fly wheel and made sure it was long enough to catch on part of the engine stand. Then I took an impact to it.

Plenty of hands on; I've done everything with the exception of machining by blocks. When I tore down my 7bolt block (dampner side) the nut in question was clockwise (right handed) to remove. I'm known to have a terrible memory, then again this could just be a difference between a 7bolt and 6bolt. Oh and I've worked a couple diesels as well.

hey guys thanks for the respones, looks like im gunna have to take the nut off the hard way because i have no way of getting an impact but thanks again for the info

OK, not to sound stupid or anything but the block is on the deck surface right now, and I'm confused about which way to turn the nut. is it clockwise or CCW? BTW it's a 6-bolt.

Put two opposing flywheel bolts into the rear of the crank, and wedge a LARGE screwdriver between them. have a buddy hold it in place (or wedge it against the engine stand), and use a breaker bar to remove the sprocket bolt. And it's CCW to remove it.

Don't know what kind of car you are wokring on but both 6 bolt and 7 bolts are ccw to remove that stud.

I agree.

My 94 7 bolt tightens clockwise like my 6 bolts did........I put the dampner on yesterday

 

[espinelli]

My apologizes guys, I have a horrible memory. Regardless, just use an impact gun when doing this. It will make the job a lot easier.

Put two flywheel bolts back on the other end of the crank. Get a crowbar and wedge it inbetween those two flywheel bolts, positioning it so that the crowbar can rest against something solid on the ground when you start to loosen the bolt.

Or you could just make a brace from flat stock just like in the Vfaq. I've done about 5 six bolt timing belt jobs and have used the brace I made every time. Makes removing and torquing the crankshaft bolt a piece of cake.

Drill two holes, make two bends and cut out one section. Bolt the crank sproket to the upper engine mount.

And yes the bolt tightens clockwise.

Just for shits I took a big wooden block and jamed it between the crank counter wieghts and the inside of the block and broke it loose that way. IF the motor / head are junk or you don't need them anymore you could take a block and put it in a cylinder on top of the piston and put the head back on and loosen it that way. You could make a bracket that runs from a flywheel bolt to the engine / trans mounting bolt and lock the flywheel that way, or you could take 2 flywheel bolts and a crowbar to hold it while someone else gets that nut loose. Any of those methods work, but I always just use the impact gun.
