Flexplate/Flywheel interchange question

[ChevyToughRebel]

I just wanted to verify with others about an issue im having. Doing an engine overhaul on my 89 camry with the 3SFE, auto, 8 bolt crank. Did some research online and to the best of my knowledge the older 3SFE engines had a 6 bolt crank, and flywheels and flexplates are supposed to be able to interchange if you did a crank swap from 8 to 6 bolt and vise versa.

Soooo I got an engine core out of an 88 camry with manual trans from the wrecking yard that had a 6 bolt crank and thought all I had to do was find a 6 bolt flexplate and I was good to go.

Instead of going through the wrecking yards to find one I thought I would check online and found an auction on ebay for one, came with all of the bolts and bolt flange for crank bolts. The auction listed said the 6 bolt flexplate came out of an 88 camry auto. When I got it and matched it up to the original flexplate out of my camry, it was about 1"-1.5" inches smaller in diameter!

I have come to 3 possible conclusions. 1) My research of flexplates and Flywheels interchanging on the 3sfe is incorrect. 2) The person that sold the flexplate on ebay had the wrong info about the part/sent me the wrong part. 3) The flexplate did come out of an 88 auto Camry, the engine just wasnt a 3SFE.

Any help is greatly appreciated! Ive already had the engine machined and it is assembled. Just need to get the flywheel issue straightened out.

I recently pulled the A/T out of my 1990 Camry 3S-FE with an 8 bolt crank and flex plate, and put in a M/T with a 8 hole flywheel. The flywheel was new from Advanced Auto. They are the same outer diameter and would have to be to line up with either the M/T or A/T transmission housing to engage the starter. The 6 bolt flywheel out of my 1988 M/T Camry 3S-FE also appears to be the same outer diameter.

In short they all appear to be the same diameter. I didn't actually measure them, but to the naked eye they look identical. I can take measurement of the parts I have left over laying around, the 1988 flywheel to 1990 flex plate.

^^^ Good point. If the starter gear ring is a different diameter, its the wrong part. All the starters/transmissions are 'compatible' between all gen2 Camrys (4 and 6 cyl, AT and MT)

Most of the 4cyl Camrys came with a 3Sfe, are the flexplates and flywheels compatible between the 3sfe and any other engine that was available in the Camry? Im just trying to find out if its possible for the camry to have another motor from the factory besides an S series engine, and if so if the flexplate could possibly be a smaller diameter. Would like to find this out before I start accusing the seller of sending me a flywheel that wasn't out of an 88 auto Camry.

Thanks for the input so far!

All gen2 Camrys have the same diameter starter ring. This is true for the S-series motors, VZ series motors and even the MZ and AZ series motors. In other words, all Camrys from '84 through today have the same diameter starter ring... You probably have something from a Celica with an A-series motor...

It is probably an honest mistake by the seller, but it still sucks.

Finally got them measured as promised. The over all diameter, that is to the tip of the teeth on the ring gear, is 12". Both the flexlate from the 1990 8 bolt, and the flywheel from the 1988 6 bolt measure the same.

You have the wrong part.

Thats what I figured. By chance I was able to verify today at the wrecking yard that the flexplate I got from the seller on ebay is from a corolla. Hopefully he will be reasonable and give me a refund if I send the part back. Thanks for the help! Now I just gotta find a 6 bolt flexplate :/
