Basset down - Balancing a Dual Mass Flywheel?

[jade]

I spoke with basset down in regards to balancing my ADU motor & I have being told that they will not balance a motor with dual mass flywheel, only normal flywheels

Any advise on who could balance my motor

Aelred on here is an I5 guru

Get a 3B flywheel on there if you can't find anyone else.

Agree with andys comments, best thing to do

[Jamo]

Really? Speak to Aelred he got my crank balanced.

This will help you understand why Phill would not balance a DM FW

That doesn't explain for me why he wont?

When balancing load is applied to the clutch system is it?

[terrybullwon]

wrong link. Sorry, i'll fix it

[Rusty]

If I had to be honest, I've not noticed much difference in vibration between 3B and ABY FWs apart from at 1400-1500rpm. That could be the transmission mounts tho. If it's all getting balanced then it's a win-win decision IMO.

I would like to keep the dual mass flywheel I will try to contact aelred

Dual mass flywheels are difficult to balance as the 2 halfs of the flywheel do not end up constantly in the same position, ie: idling and engaging (load) hence difficult to accurately balance, as you cannot simulated load on the balancing machine
Apart from BDB there is another balancer local to me I can ask him, having said that I never had a dual mass flywheel balanced.

Thanks for the repile I would like to keep the dual mass flywheel as i have read other peoples probelms with the 3b convertion & also for driveabilty as this is a road car not track car.

After going through all this work it would be good to have the engine balanced

Any contact or advise welcome

It seems like a no-brainer to me. Get a stock 3B flywheel and clutch, and get that balanced. Or are you saying a 3B isn't drivable on the road?

[Acidburn]

Think its more aimed at the aby/rs2 duel mass feels more refined than the 3b.

I still think that the 3b ain't that bad, mine was smooth enough etc

[Rusty]

As you're having it balanced there shouldnt be much vibration from a 3B FW anyway as it will be balanced...

[jade]

After a discussion with aelrad by email, it looks like the way forward will be to convert to a 3b flywheel as i imagine a balanced 3b set up will be better than a unbalanced adu set up.

How about the front pulley, this must need changing also.
