Dual Mass Flywheels

[TimberCutterDartmoor]

Suspect mine is on the way out - judder in the driveline (estate car), the shakes under high load, a little vibration through the clutch pedal (but none in neutral). In my case the potential cost is thousands -

 

Plus, also in my case apparently it can wreck the main bearing since the high compression (v6 diesel) causes it to run out of balance... Some grief for an engine with 45K on it...

 

Any advice ???

 

I know, it's an off the wall one...

John are you sure your not going in at the deep end a bit...? Have you checked stuff like props, cv joints,worn sus/ engine/ gearbox mounts, warped hubs etc etc as these sort of things can all create weird judders too? Just hoping its not what you think mate.

Just had to have one replaced on a ford ranger.... thank god for warranty!!

 

I'd get it checked out ASAP at a good garage mate..

Engine mounts were my first thought and I'd love it to be that simple. Just that this particular Isuzu 6-pot is known for the flywheel going bad... If it is I can't run it - doing so can render the block scrap - imagine the proverbial I'd be in!

keep a good eye on your prop u/j's, they wear quickly on these!!!

[Cracker]

Sounds like a prop uj to me.

There is no prop - being front wheel drive. Have googled "symptoms of dual mass flywheel failure" and in relation to Saab 9-5s with the 3 litre diesel. I'm 99% sure it's the problem. My word, I hope there's some comback from the dealer - only bought the car on friday!!!

Ever since these were introduced I've heard nothing but bad things about them.

 

The dealer will probably be ok about it, they don't get chance to thoroughly check and test drive every car.

 

Good Luck

burn it

I hope you're right Dean; wasn't a Saab dealership though, just a legitimate used car sales co. Vehicle has full Robert Bowett (Leeds) service history too

 

My reading suggests too that they are nowt but trouble; fitted to high torque common rail diesels in particular (which mine is) to iron out vibes.

 

Cost of flywheel is a couple of hundred but the time to change it means mega labour bills which I simply can't afford. I guess it's a ramp job, seperating block from gearbox (drain fluids?) and all that?

 

Should possibly do the clutch at the same time?
