Cutting teeth (from a flywheel)

[coulomb]

For those converters that retain the gearbox and clutch, here is the way to remove the teeth from the flywheel and save a little weight and inertia:

We machined ours on a lathe. Took off the teeth and machined the front face flat to make a nice fit with our taper-lock hub. It's hard to tell in the photo, but...





It's the part between the clutch (right) and the profile plate (left). After machining, we took the flywheel to an automotive machinist to have it balanced. Note the drill-press marks on the outermost surface.

thanks for sharing

just wondered if you expect to be changing gear alot with that motor having such a wide torque and RPM range

could you have done away with the gearbox and clutch completely , saved alot of weight and just direct mounted an IRS diff to the electric motor from something like a WRX , your motor is reversible so you wouldnt have to turn the diff upside down , ( you might need longer axle shafts though between the CV's )

there is a thread here somewhere with photos of a barina using that method

cheers and good luck

edited to correct the use of " driveshafts" when i meant axles

I have to say that when I tried this, it wasn't as easy as it looked. I had to drill quite a hole, which was hard work, and then it took a lot of bangs to get it off. But it certainly did come off. It might have been easier to just cut it off with a hacksaw.
