Per Chilton's instructions, I loosened the three back subframe bolts, removed the three front subframe bolts, and used a jack to lower the front part of the subframe.
The pulley did go down a little bit with the frame, but it seems that the frame went way down while the pulley went down just a little bit.

I don't know what's in the way of the pulley going further down so that I can install a pulley removal tool. Right now the pulley's not down enough.

The picture shows a mount next to the pulley. Is this mount preventing the pulley from going lower? If so, how do I remove it? Do I also need to remove more mounts?

Also, since I'm replacing the pulley with a new one, can I just heat the bore area and pry it off?

Thanks.

You remove the LOWER nut at the BOTTOM of the mount.
No, heating it alone won't do it. A puller is required.
Somewhere in my poor memory, either Cadillac or Buick had an engine that the HB was a SLIP fit, but can't remember who or when.

Crank pulley/harmonic balancer- Special torque + degrees of bolt rotation to install............ or you have no oil pressure.

37 lb/ft + 120 degrees of rotation with the engine flexplate locked.

#11 - oil pump drive spacer - friction-driven by the face of the balancer hub.

As an aside, why are you removing the HB?

Got it. It was the lower screw. Pulley came out. Now for the hard part-installing the seal :suspect:

Thank you guys for all the answers.

Okay, time for the seal. The picture shows the seal just placed by hand over the hole. (The pulley shaft had eroded throughout time, making the pulley wobble). Back to the seal: The seal is practically impossible to "set in straight" in preparation for a PVC pipe to be used to mallet the seal in. I tried the PVC pipe gently and noticed that the seal is going in crooked--part of the seal goes in further than another. Any ideas would be appreciated.

Practice, practice, practice

Or

You could use the pulley bolt with a proper force transfer device to push the seal on (ie bolt, washer, washer, steel flat plate, pvc, seal

I have an assortment of hardwood dowels for just this problem, and a small stubby ballpeen.
don't let it get cocked more than 1/16" or so before straightening it up. Slow and easy, don't go deeper than the original.
And be sure that snout is polished to perfection!

If any doubt, go get another seal, or it will have to be done again. This is no place to 'hope' or get 'lucky'.

I don't need to tell you how I know this. A couple times in a lifetime is more than enough.:mad2:

Got it. Practice, practice, practice. Now for putting everything together the and getting proper torque on the bolt. Thank you all.
