on a 3.2 be replaced with the normal flywheel (and clutch) from a 'lesser' model?
:y
-
er, no !
at least not with standard kit anyway.

why not ???

Put an auto box in!!!! ::) ::) ::) ::)

All Omega manuals come with DMF.
Whats wrong with your DMF?
-
I dont like it ;D
Basically, I feel that the v6 would be livlier with a 'normal' fly, that and I could uprate the clutch on it. :y
Ive heard rumors of people fitting red top flys on 2.5's...?

Well it wont be livelier....thats the thoughts of people who cant apply logic to it!
The option on a standard fly wheel would have to come from a Cav or Calibra V6......you then need a different friction plate to the Omega one as the Omega variant does not have the cush springs built into it.

cav or vectra non DMF flywheel won't fit in Omega, either.
the friction face is further away from the rear face of the engine on Omega to give room for the dual-mass gubbins. So with the "transverse" flywheel, you'd run out of release bearing travel before releasing the clutch. you could, of course, space out the release bearing assembly, but that sort of thing isn't exactly a straight swap.
the Cav or Vectra flywheel isn't going to be that much lighter than the Omega one, and if you want it to be "livelier", then you're really after a flywheel with a lower rotational inertia. That's aftermarket territory.
I dislike the DMF, too - it's fine for comfort and low NVH, but not really any good for more sporting ventures. I had a replacement aluminium flywheel made for the Omega Evo.
Just for reference, the DMF applies both weights to the engine when you're out of gear (smooth idle), whilst applying only the inner weight to the engine when in gear and driving - the outer weight is applied to the transmission to dampen drivetrain vibrations.

oh yes, the bolt pattern is different on the four cylinder cars

I know 2 people who got done conversion by use parts of cav/vectra( clutch and flywheel)and fit in to omega and they dont have any proplems since job done

Reality is, it may help the car rev faster in neutral, but will only have minimal effect whilst driving - the inertia of the DMF is minimal to that of the car.

As it happens, I have all of the components, so I'll measure again just to make sure. It might be that the release bearing has enough travel to reach the new clutch position.
Any chance of asking either of them if their biting point is any closer to the floor ?

Legend :y
The main reason is I give the clutch a fair amount of abuse and the DMF and clutch just arent as good as normal set up.
Chances are it would be cheaper than a replacement 3.2 clutch too, so if there is an easy solution using existing parts, then it could work well for more than just idiots like me! ;D

The hydraulic system should take up the extra clearance and give the same biting point BUT.....
if the slave cylinder reaches the end of its travel and pops out of the end you will have a puddle of fluid in your bell housing and no clutch realease :(
Also.. if the gearbox input shaft isn't long enough the driven plate might not engage the splines and/or the nose might not engage with the spigot bearing.

The clutch I just picked up for my tractor (same one I believe as the 3.2) Sachs Brand (LUK Stamped) was only 77 quid... I saw Cav ones for around 40 + postage, but, I didn't look to see what power rating...

I think the "concentric" clutch cylinder on Omega B has a positive stop which would prevent it popping out. It would prevent any clutch action beyond the stop, though.
all of the input shaft choices are the same length ( apart from gearboxes for CiH )
also apologies for not posting up all of the dimensions - I'm having a mare of a day - someone drove into the back of the Holden this morning

Sorry to hear about the smash mate, hope all is ok?
And the 3.2 clutch is unique to the 3.2, main dealer only and made of cheese (for my abuse anyway), tractor one is different afaik.
If a tractor one will fit, the result as being diseasal means its potentially beefier
