Flywheel

Since my original flywheel just got turned for the last time I thought I better pick up a spare so I bought this one:

Besides the lack of the orange paint daub does this look to be a hipo flywheel? Engineering number is correct, hope I didn't make a boo boo...

The flywheel thing has been discussed a few times around here and despite what the books say a C3OE-B Engineering number is not HiPo specific. The HiPo unit will have an orange paint daub but even if that is missing all original HiPo flywheels I've seen also have an obvious Brinnel hardness test mark and are balanced differently. If you can see the test mark it's likely a HiPo flywheel. If not it should be no big deal to have the one you bought rebalanced to HiPo specs.

Hmmm, you seem to have found the posts I didn't find.

Probably paid too much... we'll see when it gets here I guess.

Ok, I can't find any brinell test marks on this flywheel but does have a number 6 stamped on it. Date code is 6G21. Weighs somewhere right around 19 lbs on the bathroom scale. Definately had a 10-1/2" clutch run on it from the wear marks. Guess I'll have to take it up to the balancer to see where it's balanced...

Would a service replacement part have a hardness test? This flywheel looks to clean to be an original.

Merlyn, the auction pic (which is terrible as usual) almost looks like there is a "smooth" area in the 2:00 position on the thick pad. Is that real or not? If real look for the "BB" impression. If the flywheel has been hot tanked and/or bead blasted may be hard to see the test mark. Dave.
