Would you trust a dual mass flywheel next to your plates of meat:eek: :eek:
when this kiddie let go it came through the bellhousing.

I wouldn't trust a DMF to do anything but fail, they are the work of the Devil! Most ridiculous solution to a non problem ever dreamed up.

Talking to a Ford "engineer" at Goodwood while looking at their new three cylinder direct injection petrol engine I was intrigues that they were using a DMF, the reason given was tht they had no counterbalance shaft and so needed the DMF to compensate. He lost credibility when discussing the timing belt that runs in an oil bath. I asked Why? Would it extend the lifespan of the belt? "Oh yes says he". "So what kind of mileage is this belt good for?" says I.
"Ooh let me see..................30,000 miles or so I think".

"Really? dry belts are generally good for 60-70,000 miles, why bother with a system that gives a shorter lifespan and makes it more difficult to replace?"

"I don't know really, I was involvoed mostly with the combustion development"!

So this is progress?

Diesel has them aswell,catastrophe when they fail and nightmare to fit.

Hmmm DMF is mainly used to smooth out gearchanges and the resultant enmissions spikes on the drive cycle, you'd have though a combustion specialist would have known that:eek:

Still soon the days of manual change will be gone and hopefully the dmf with it:D
