If you are talking about the gear on the crank not sure it can be removed.

gear and install on new crank.

Do you mean the crankshaft pulley/harmonic balancer?

Have seen this also but don't know how it comes off.

Is the crank out now. Any screws, bolts, etc.

The crank is one solid piece. The gear would need to come apart into two sections, it could never slide off.

Not all cranks are set up to receive the gear, assuming it can be removed and transferred. If transferring make sure the new crank is designed to accept the gear.

The number of teeth on the gear may have been changed around 1994 to quiet gear noise.

My FSM shows the gear but does not discuss how to remove it. The crankshaft is cast and machined as one piece so if the gear is not a two piece then you'll need a new crankshaft to fix it. Got a picture?

Would concur, but have seen the statement about transfering over the gear to another crank. And that the new crank must be setup to take the gear.

Post Solution:

Yes, the gear does come off. I just had a local machine shop press it off. Even though it's 6" or so in diameter, it's only 1/2" thick, and maneuvers its way off and on the crankshaft.

To put it back on, the shop heated it up to expand it. They mentioned that you don't want to heat it up too much, or it would lose its tempered characteristics. Didn't follow up on that, but it makes sense.

So, long story short, take it to your machine shop. They may need to get creative to press it off, but it can be done. It cost me $40.
