I have two flywheels that I removed from 2 different A-series engines. One from an A12 & one from an A14. The A12 looks lightened substantially, its diameter is 9 7/8" , theres approximately a 3/4" deep recess from the ring gear surface to the clutch surface. The A14 one is 10 3/4" diameter & flush across the surface. It looks like comparing the two that the A12 one has been milled down quite a bit.

I took pictures & tried to upload but I cant seem to get it to work right. I resized them & tried uploading but still no go. Ideas anyone?

what are the standard diameters of flywheels for these motors ? I thought they were the same diameter through the A series line, am I wrong?

Thanks, Evan

OK, I posted some pic's to the site. they are pic #'s 465 thru 468.

If somebody can tell me how to get them into this post that would be great.
Thanks, Evan

I thought they were all the same diameter. Could one be from the B-210 with 5-speed? It used a larger transmission & clutch.

For posting pics to the club Photo Album, it depends on the message you received back. See Photo Album FAQs.

The one where the clutch sits inside the flywheel is from a front-wheel-drive car, probably a 76-77 Datsun F-10 (E10) or a 78-82 Datsun 310 (N10)

My problem with uploading was simple - too big! I posted them at 640 x 480 & up they went just fine.

I'm wondering how all these strings end up with photo's posted in them. Can you attach or upload when your starting a new post?

No, but you can add them manually. It's in the FAQ, see "How Do I Link a Photo into a Discussion Topic?".

I had an F10 once, I have no idea what the flywheel looked like though. Would it have been a smaller diameter?

Would the previous guy have used it on this motor for weigh savings or some such? My plan had been to bench run this motor & I needed to put a started on it so I pulled the flywheel for an A14 I had to get the cover/protector plate to swap onto the A12 & then took this flywheel off the A12 & I found the differences then.

It even looked like someone had previously milled the bolt heads down, they had a very shallow head on them, approx. 3/16" high.

Neither of them look much like A series to me
The one on the left the recessed one... NFI
Never seen one like that before on an A
The one on the right.... strange that it has a step on it
Toyota do that
20 thou step
More clamping for no extra money
My race flywheel is like that though
Usually A series are flat across the face

I have a third A12 motor in storage that I'll pull the flywheel & compare that to the others. the one with the recess is at least 1/2 the weight of the one off the A14, thats what made me think its been milled down.

They both definitely came off A series motors, it'd be nice to know diameters of stock flywheels for A12's & 14's if anybody knows.

What motor is standard for an F10?

Thanks, Evan
