Flexplate Spacer

[1993Saturn]

I was going to replace the Flexplate to crank spacer. What is the ID of the spacer hole?

Also, what is the allowable runout of the Flexplate? I measured mine with a dial gauge right at the spots where the 4 mounting pads of the T/C contact the flexplate.

Glad I had the little skinny wrench for the fan to turn the engine. Sure beats accessing the damper pulley to do it.

Yes, this was the exact same choice I had made after reading a post by Brain. I wanted to know the OD of the pilot on the T/C where it sets inside the spacer and the ID of the spacer. I would like to compare to my current bad parts and to check on the new parts when they arrive.

Also, what is the allowable runout of the Flexplate? I measured mine with a dial gauge right at the spots where the 4 mounting pads of the T/C contact the flexplate.

What about these runout specs as well. Any info on this?

Thank you

The center hole of the spacer is 3/4" in diameter. This is one of the links in # 9 in my list of useful threads: http://www.sonnax.com/tech-articles/TASC-TIP-10-04.pdf

Thank you for that link. I now know about the longer TC pilot. The most important question is the one listed below, so I know if my flywheel is good or bad. I really appreciate the help on this. I don't want a 3rd failure because I didn't know enough information.

The holes shouldn't have any excess play. Do they look oblong or egg shaped?

If you are asking about the mounting holes in the flexplate, they are fine, no distortion. What I want is to know how much runout is within tolerance at each of those holes. The T/C makes a contact ring about 1/8" around the hole. I turned the crank to each of those spots. With the dial gauge passing over each of those spots, I got the following measurements in a clockwise rotation: .000", .004", .0055", .003". Is this OK? It is also the old style flywheel with the reinforcement welded to the center by 3 spotwelds.

Those measurements seem like small numbers so the holes can't be off by too much.
