3B flywheel wanted.

[gnutz2]

Just checking if anyone has a 3B flywheel FS before i contact sal.

If there was one in the north it would be handy

[Sonic]

Been after one for a while also, with not alot of luck!

[GazzaG60]

i got a 7a one instead. i looked for 3b and any i found were silly money.

i got a 7a one and will have it lightened. anybody any experience of this and whats safe to take off a 7a.

[Rusty]

I believe the 7A is 1kg heavier than the 3B so whatever you can take off the 3B + 1kg might be help?

Tried All Audi for 7A ones, should be able to help.

[GazzaG60]

i got a 7a to replace the dual mass. i expect it will be lighter than the dual mass anyway. i got a sachs uprated clutch kit to go on too.

hope its worth it.

From the images i have seen the 7A has additional weights on the backside of the flywheel, just machine them off flush and it should be hear identical to a 3B item.

I believe this is a 7A flywheel with the weights removed


My 3B flywheel


I would say both flywheels together weight less than the dual mass version

[Rusty]

Have you got a DM to measure. I've seen lots of weights in the teens but the difference in the way the car drives indicates quite a large change.

[Jamo]

It's about 3kg difference between the dual mass and single mass.

There's a thread with the weights.

The difference with the dual mass isn't the weight so much, it's the fact it's got dampers to absorb vibrations that makes the most difference IMO

[terrybullwon]

so the dual mass is about 14kg?

[GazzaG60]

thanks for the pics. ill have it machined flat plus a little more.

[GazzaG60]

ill weigh mine when off. it wont be till its warmer though.

[Jamo]

so the dual mass is about 14kg?

Gold star for Chef

3B flywheel 10.5kg
7A flywheel 11kg
ABY flywheel 14kg
3B pulley 4.26kg
7A pulley 4.3kg
ABY pulley 5kg

[GazzaG60]

not having seen a 3b or 7a pulley bearing in mind i have no aircon is a swap from an aby to a 3b/7a front pulley a viable option worth looking at too.

You cant as the ABY uses a multi belt and the 3B/7A a v belt.

I got my flywheel to 6kg
