What's your opinion on the condition of this flywheel?

[FWP]

Whatch think? There's some minor heat cracks that didn't show up in the pic.

I thought flywheels were all silver and shiny , or is it a Dodge thing ?

Definitely needs surfacing. Plenty of heat scoring too huh? Mine was nearly that bad, but it cleaned up just fine.

Burn marks all over it, the heat cracks won't affect anything but that flywheel needs to be machined.

Interesting. Just got of the phone with Peter from Southbend clutch. This is completely normal for a Cummins. Dress it up with a flapper wheel on a grinder, done.

Seriously Fred, you'd "dress it up with a flap wheel" to save $20-$25??? That surface needs to be flat not just prettied up. A flap wheel disc on a grinder is going to ruin that flywheel.

^^^^Very true!!!! Have that thing re-ground at a machine shop, no wories. If they try it on a lathe make sure they don't get it chucked up wrong and put some nice run-out into it.

if they do it on a lathe, find someone else. its almost impossbile to get it perfectly square on a brake lathe.

South Bend clutch... yeesh... if i could tell you the amount of crap that i hear about that comes out of that shop.

Even better.

On a low power budget build it'd be one thing, but with the price of those Cummins clutches, I'd get it done right.

This aint my first rodeo . I just thought it interesting what was said .

BTW, whoever mentioned a lathe- flywheels are not professionally turned on a lathe. They use a stone and a tool designed for flywheels- FYI.

Can you elaborate? First hand experience? The guys on TDR swear by them, for the most part.

 

[beater_k20]

living within 20 mins of South Bend, alot of the racers around here use them. they just dont last as long as other clutches.

Thanks God Fred, I knew you had more sense than that.

I believe they use a surface grinder for flywheels...
