Wrong Flywheel with conversion clutch

[Chuckmeister]

From the way it acted, I figured I had a cracked pressure plate spring as well as a disintegrating dual mass flywheel. I bought a Perfection conversion kit from Rock auto. Since my 89 7.3 doesn't have a turbo, I chose the Perfection, rather than the Valeo which was for aftermarket turbo. I have the Perfection installed and the ring gear is too large. The starter won't engage. My question for you guys who have been swapping stuff around for years is, is there a starter that would have the drive just a bit farther from the flywheel, or is there a solid flywheel that would accept the pressure plate. I can't find specs on bolt diameter and Rock Auto isn't much help. If I can find contact info for Perfection I'll look there. Any thoughts. Much appreciated.

You should have went with the Valeo. its for NA or aftermarket turbo.

Find the number on the box and plug it in. See what application it's for. I know it's already in the truck, but I wonder if you could get any numbers off the actual pieces.

I say this because I bought a set of rear brake shoes for my truck from RockAuto. I went to put them on, and they would not fit. I looked the numbers up online, the numbers on the box were correct, but the numbers on the actual shoes were different and the wrong ones. I went on RockAuto's site and was going to do a return. They had this little routine I had to click on and they wanted to know the numbers on the box and the numbers on the shoes. After I plugged that in, it told me just to keep what I had, they would send me another set. They were the right ones that time. It was pretty painless, but you can't get in a hurry, it took a few days.

Good thought to look on the box. If I can come up with a part number for the pressure plat, that should make it easy to match with a smaller flywheel. I've found other suppliers who give more dimensions. Looks like my original flywheel is 15 11/16. Somewhere I've seen the one that is now in the truck at 15 7/8. They all seem to have 55 teeth. Short term, I guess they aren't fussy about good meshing with the starter. Thanks for the tip
