My patrol got a solid flywheel and h/d clutch installed a week ago and a I happy with how it goes but just a little concerned about the extra engine vibration at highway speeds, around town it's great but while on the high way there is a bit more engine vibration, I have searched and got mixed answers about how much vibration a solid flywheel should create, thanks for any input.

Thats why they have the dual mass wheel from factory... to damp out bad vibes.

It will probably be hard to judge what you are experiencing over the 'net. What is acceptable or expected by one person can be hard to describe to another.

If it was a reputable mob who did it get them to check it again on a road test maybe?

It was a well known place that did it so maybe I'll get them to take it's for a spin on the highway

Chnage out Dual mass flywheels.

My patrol got a solid flywheel and h/d clutch installed a week ago and a I happy with how it goes but just a little concerned about the extra engine vibration at highway speeds, around town it's great but while on the high way there is a bit more engine vibration, I have searched and got mixed answers about how much vibration a solid flywheel should create, thanks for any input.
It's too bad you didn't do more research on this site on this matter, as it's dealt with in depth on many occasions.
I would council to ALWAYS REPLACE your dual mass flywheel with ORIGINAL parts.
The reason I say this, is because I was talked out of doing this, when it became neccessary to replace my clutch, I was told a solid flywheel would be better.
But no one explained to me, what it'd be better for.
I allowed the so called 'experts' to convince me to go down the sloid road much to my REGRET.
YES, there IS vibration there, and YES, the whole purpose of the dual mass wheel is to ABSORB such vibration in the first place, there's also back lash from the wheels when changing down, all normaly absorbed by the dual mass flywheel.

So, would I replace the flywheel again with the ORIGINAL DUAL MASS set up ?
In a heartbeat :punkrock: course it depends on what sort of ride you want, and how many pennies youve got.
I seriously doubt very much, that the guys who fitted it can do much about it.

^^ what you say is correct, but if you increase the engine performance from stock then the dual mass flywheel will fail.

So you get more power out of the car, then you smash the springs in the dual mass flywheel. Then you put a suitably rated clutch in. You put a dual mass flywheel back in you'll smash it again and again unless you reduce your power back to stock levels.

Just had 4terrain clutch and solid flywheel fitted to my 2004 zd30, and it is great, good feel no noise or vibration even at low revs, those standard DMFs are crap and will always fail well before a solid one, it is just another problem that has arrisen in the patrol zd30, and if you tow, well a DMF will fail quicker.

Has anyone thought to machine down the new steel one piece flywheel to make it lighter and give the engine better performance.
