Increasing the life of a dual mass flywheel

[Searider]

Anyway, what I dont get about these DMF's is that they are there to protect the engine/gearbox from shocks through the transmission. How come then they dont have them on tractors and plant gear? A 400hp, 12 litre, tractor will send massive shocks through the transmission when pulling hard, and yet they dont have a DMF? Okay, the whole unit is bigger, but proportionally not massive.

A 400hp tractor will be an auto box anyway?

Unfortunately a DMF is usually regarded as a "wear and tear" item, just the same as a clutch, brakes or tyres.

It will depend on the dealer though.

Best of luck!


Oh, and don't even think of fitting a solid flywheel, a quick search will tell you all you need to know!

Not true - a sprung clutch and solid flywheel combination can, in some cases, replace the dual mass flywheel. My car is an example of this - same engine in a transit has no dmf, thus, you can replace it with transit parts.

My understanding is that the VAG cars' gearboxes aren't quite as agricultural strong as the ford ones, but I could be wrong.

I'm sure they'll probably try that argument and if the car were higher mileage it might be understandable, but certainly not at 30k. They're designed to last the design life of the car which is definitely over 100k and if you google dmf and warranty it brings up loads of cases where the dmf is covered. So I can't really see how they'll get around that but even if not for the warranty I'm sure they're liable under the sales of goods act given I only bought it two months ago.

Thanks, I may need it!

I've done a 100K without giving the DMF a single thought, it's been faultless, and I do every thing 'wrong'. Either yours was sub-standard from new, thrashed to death, or massively clocked. Whatever, it is just bad luck/unavoidable. Like any other random car problem, there is no reason why a replacement will need any special driving consideration or not last 100K+. Loads of petrol cars have DMFs these days (although they seem to lead an easier life).

What car have you got? They seem to fair better on less powerful diesels, though it's not like mine's a leon FR. This car has only had one lady owner (which I believe given all the shopping receipts I've discovered) but may well have been laboured at low revs. It hasn't been clocked which I can tell from the finish on the controls let alone the history. As you say, it may just be bad luck, but if I can make my own luck i'd be more optimistic

Since the Mk6 transit was introduced in 2000 it was fitted with a Dual Mass Flywheel. Ford haven't produced single mass flywheels for transits since the 2.5Di engine fitted to the smiley face transit.
