Hi I have a 2002 Gu 3.0 litre Patrol with 101,000 KM on the clock I have just replaced the clutch and have also replaced the flywheel after it was advised to me from the clutch specialist that it was at ,
that it had to much movement in it. I rang Nissan
Melbourne Head office to make a claim and they advised me to put it down in writing so I did.
They wrote back with that the extended waranty would not warrant this and if I would like to take the flywheel to the designated nissan service centre for another opinion, which I did they believe that it is
still okay and they wouldve left it. Since this i went back to the clutch specialist who did the work andhe is sticking by that it has too much movement in it
I guess Im asking has anyone had similar issues with the 3.0 litre

Just a quick question?
What part of the fly wheel had too much movement?
A flywheel is a big lump of machined metal, is it the spigot bearing that is shot?
Usually all that is required is the face to be machined.

I think they are "Dual Mass" wheras there are 2 independant parts, the bolt section has some movement in relation to the friction surface. This method is used to improve idle quality.
Quite common. Commodores (At Least around VS) use them as do BMW.
They can have quite a lot of movement, maybe 10-15 degrees and still be ok in the case of BMW.
Good Luck
Greg

The 3.0 has a damper flywheel, 2 part pressed together and oil filled, to stop the engine vibration that wears 5th gear splines off the main shaft and gear....
They do crack around the bolt holes, leaking oil on some, also, if you machine them, no warranty, and they dont like to get hot, slipping the clutch.
I dont see, unless the "movement" can be measured, and proven, how it would be possible to blame it.

Not sure about the degree tolerance but 25mm in the max.
We don't put the dual mass flywheel back in.
We fit Daiken solid mass flywheels to both Patrol 3.0 and commodores. Haven't had one come back yet.
We did fit one new Dual mass flywheel a few years ago and the taper on the mating surface was incredible. I would not have liked to have had it put in my own car and as they are not recommended to machine them, they are what they are.

Hey 120scruiser
Does that mean with the Daikin clutch fitted more vibration is felt through the car, because it isn't the dual mass oil filled job, or do the Daikins fix all the issues?
cheers

Gday Andrew.
The last one we fitted, April this year, I took it for a run without the gear shift rubber boots fitted. Yes I did notice a noise, no where near as bad as my old 80 series but once you fit the boots no noise. The customer is wrapped as the clutch feels great and not spongey any more and it doesn't give that slipping feel.
I suppose time will tell.
The commodores we do come up with a fantastic clutch pedal.
All the customers have said its the best clutch pedal they have had.
Like everything, its a compromise.
My opinion on 5th gear is if its going to go its going to go no matter what clutch is fitted. I think its a fault but I have no evidence to prove it otherwise.
Try this link which is our experiences in our workshop.

Cheers for now

I forgot to mention Andrew the clutch conversion kit was $1900 retail which is cheaper than a new Nissan flywheel.
If it goes again in the future all you have to replace is the clutch kit itself and the flywheel is machinable.

dasmper flywheel is to stop vibration, which causes spline wear at rpm, on hwy, like 5th gear issue, so solid replacement may not be felt, as to stop harmonic, but may be felt many km down the road by components.

I think what Darren is trying to say is that the solid state flywheel may be a short term fix but could inadvertantly cause problems elsewhere.
5th gear splines wear on the gearbox's even with the dual mass flywheel and maybe Darren is right.
Like I said earlier time will tell.
Unfortunately these 3.0 motors haven't been around for too long so we are all learning as we go.

Thanks for the comments
It was the movement between the plates in the flywheel that is the problem I suppose I should have given it to nissan to do the work.
When fitting the solid flywheel do you have any vibration problems plus how would this affect the warranty ie gearbox etc could nissan blame this or use this as an excuse on other problems.

Nissan would find any excuse (as would anyone else) to get out of a warranty claim.

Warranty claims are under each dealers discression.
Unfortunately what one dealer won't approve another dealer will.
Obviously if the clutch/flywheel has been changed, it won't be covered under warranty. How this affects other items is undeterminable. (Is that a word?)
An example of discression is - I had a daewoo with a coolant leak between the head and block. When coolant leaks and hits the atmosphere it crystalizes. This was evident and had leaked from the headgasket and was hanging down the block a good 3 - 4 inches. I will mention the dealer as they are shocking, Penrith Nissan said there is no evidence of a leak. I informed the customer to try a dealer closer to his work, Parramatta and they wouldn't give it back to the customer until it had been fixed, under warranty. This is the difference between dealers.
Some are good and some are terrible.

When it comes to Nissan warranty claims it's not up to the dealer but head office. Head office don't let the dealer decide what needs to be done. That's why the dealer has to get back to you all the time as they check with Head office first. Holden on the other hand I have found to be excellent as they fix things on
the spot and are allowed to use their discretion. This actually puts me off buying another nissan.
