I used TVD shell ATI917020 on my engine - it is available from multiple sources. I got my original from JEGS, and just got a second one (for test fitting the production hub) from Summit Racing.

Recently met with the machine shop - hub fabrication scheduled to be complete in 2 weeks, then out for anodizing, which will be another week or so.

Great! My motor reassembly is coming along so I’ll be needing to get the damper put back on in a few weeks :jumper:

Sorry for the delay, but the shop had a China Virus case, which slowed things down.

I'm scheduled to pick up the completed parts this morning - hoping to get it done before the pending snow storm here in NJ. I'll post pictures, pack them into the nice little boxes I bought, and start contacting the interested parties. One was delivered to a customer about 10 days ago (emergency need - he took the part unfinished, without anodize, shipped directly from the shop - I never even saw the part). Everything went well, but it didn't go on all the way before it cooled (he worked around it), so, I posted revised installation instructions raising the soaking temp a bit from 250F to 275F. Stay tuned....

Good points - I'll leave it up to folks as to whether they want the kit right away or after the holidays.

I’ll take two. Bump this thread after The Crazy Days and I’ll order them for inventory; No immediate need right now.

In case the hub cools down too much before fully seated against the timing belt guide, I revised the instructions (added STEP 3A) to show how you can use the removal tool parts and crank bolt to drive the hub into its final position. I will include the extra washer (shown in STEP 3A picture under the crank bolt head) with the kit. Merry Christmas!

Geza, I will be installing one of mine this weekend. I will give you a full accounting of the process.

Life got in the way of installing the harmonic balancer this weekend. I did get closer to it, just couldn't make it happen yet. I should be stringing Timing belt tonight, so maybe tomorrow night.

I now have everything installed prior to the HB. I will make it happen this weekend. (if the sun shines and the creek don't rise)

I installed the hub and the new Harmonic balancer last night. I had trepidations about this whole process prior to beginning the installation process. These fears were unfounded. I was afraid that I would get the securing bolts in the wrong holes. I didn't. I was fearful that I would end up with the hub halfway on and get stalled there. It didn't. The entire process, although somewhat lengthy, was smooth and everything fit well. The hub slid right on like it was made to fit there. :)

Glad it worked out for you. Did you use the removal rods as a handle? If so, did you add them before or after you heated the hub? Any suggestions on improving the instructions? Thanks

Yes, I installed the removal rods prior to putting the whole lot into the oven. Put a piece of foil down on a cookie sheet and put the whole mess into the oven. When it was time, I removed the cookie sheet and loosely wrapped the foil around the hub to conserve heat. Used good oven mitts to handle the removal rods and the hub and place it onto the crank snout. Once aligned, it slid right on. I let it cool a bit and unscrewed the removal rods.
