Answer to these Questions

No it is not  .....................*First things first mate, is the clutch slipping ?
No, tried that, wont slip.....*Can you slip the clutch with the handbrake on ?
No kick or Judder..............*If the DMF is on its way out, you normally get a kick or judder when you take up drive.


Is this right, a DMF for the 2.6 and 3.0 are the same as the 2.5, that came from a parts supplier, although Halfrauds has different
sizes for the friction plates

2.5 = 228mm dia
3.0 = 240mm dia
2.6 = anybody any info on this ?

cheers

Unlikely to need a salve cylidner on an Omega, never yet seen one fail.

Three piece clutch kit can be got for sub 150 notes e.g. here:

http://www.buypartsby.co.uk/details/VAUXHALL/OMEGA/3.0/2000/__/34/624165209/clutch-kit/

DMF on these does not cause any issues and easy to check once the box is off.

Imho, i'd be thinking about the box 

[vauxsky]

the box - really - its that simple once these points everyone has mentioned have been met - what about linkage adjustment.

Suppose I had better take it off then and have a look.

[Marks DTM Calib]

Linkage is not adjustable, its a rear wheel drive box.

[Panto Voice]Oh yes it is![/Panto Voice]

The shaft between the back of the box and the remote gear lever (hidden inside a rubber boot thing) on my 1994 Omega was very similar to the linkage on an Astra (but about 2 feet shorter )

It did seem a bit unnecessary so I suppose it could have been designed out on later cars

Does the clutch pedal feel normal? Just wondered if there was bit of air in the system that might need bleeding but im no expert and im sure I will get alot of replys to this explaining why im wrong.

That could cause clutch drag, there is a bleed nipple sticking out through the side of the bell housing that might be worth checking.

The other possible cause is the master cylinder if the seals are on their last legs.

the gearbox is out?

the clutch plate is not down to the rivets yet, but there are funny surface marks on both sides of the pad. Also, there are, what looks like hot/burn marks on the pressure plate and the flywheel face.

But, these might have been caused by me trying the handrake - dropping the clutch "test" to see if there was any slip - which there was not.

So now I need to know what to measure to see if the flywheel needs replacing - any ideas where I get this measurement?

the local parts guy said he has a diagram for the measurement of the Dual Mass Flywheel, so I might take a trip down to him to see what he has.

dmf's are expensive and so is the dmf clutch set..
 
I used 2.5 vectra single mass flywheel (machined) and its clutch(new) .. no probs..

I saw your suggestion, Standard Flywheel(Skimmed) and New Clutch - does this still work with the hydraulic
Thrust Bearing - do not need to change gearbox - use my gearbox?

Rang LUKe the suppliers and manufacturers, he suggested to test if the DMF is ok, put a bar from one side to the other(make some bolt-bar lash-up) and force the DMF down onto its springs - do this around the DMF and feel the tension - if they are all the same and no nasty sounds it is probably ok.

Be carefull not to turn the dmf too fast or you might jump the belt.

I think that if you're using the standard hydraulic bearing, you need a spacer to space the flywheel off by the equivalent thickness of the DMF?

Sure Cem/others will confirm, though.

not a big difference between smf and dmf as I remember..

"we use everything standard except the flywheel and clutch(pressure plate etc).. gearbox is getrag 240.. "

Hi CEM, I thought you said,  everything was standard except the FLywheel and Clutch, whats a Gertrag 240 gearbox and your pictures are showing a DMF flywheel?

I think I am keeping it standard, just changing the Pressure Plate and Clutch Pad.

Will just mention the Bushes on the Linkage Pin were broken too - 2 off, ordered new ones £8.0 ea from VX
