Hopefully I'll be able to scam a day off this Friday, so I'll take my car into the shop so I can use a lift and inspect my flywheel and the torque converter bolts. My question though, is what is the best method to rotate the crankshaft? On the crank pulley on my Toyota, there's a large nut that I can put a socket on to turn it clockwise, but on the slant in my Duster, whatever's there appears to be recessed into the pulley. Is it just a simple matter of getting the correct socket on/in there with a ratchet and turning it clockwise?

Remote starter switch with the coil disconnected?

I thought of that, but I'd much rather be able to turn it by hand so I can get a boroscope up in there to look around in the bellhousing and feel around the assembly with my hand.

Pull the plugs, it should turn pretty easy then. I wrap the fan belt around the crank pulley and rotate it with the belt.

Probably the cleanest and easiest way is to go get the right bolt and washer to install in the front of the crank. It's not needed to hold the pulley on, but it does make it much easier to turn the engine small amounts. The bolt is ¾"-16, 2¼" long. The appropriate flatwasher is about 2" diameter or a little under.

I think you oughta put the bolt and nut in the crank to work up top, but if I was looking for the bolts in the bell, I would use a flywheel turner. Kind of a strange gripper that fits in between a span of teeth, and as you turn, grips the teeth and rotates the assembly. Less than $6 at harbor freight.

That doesn't sound like a bad idea. Got a part number? I just checked around on their site and couldn't find anything like what you described.

I have done the same thing with a large screwdriver. It will only turn a couple of teeth at a time but it will work. The flywheel turner is definitely a better solution if you can find it.

Dan's right on with the bolt. For some reason, it is missing on many of the slants, but it sure makes it easy to turn the engine over with maximum control.

It's not missing...it wasn't installed on most of them, 'cause except for convenience in servicing, it's not needed. The crank pulley is an interference fit on the crank.

And if you have one, and not have the spacer behind the fan, it can
be a bit tight between the fan and the bolt.
