Omega General Help / Re: Dual mass to solid flywheel conversion - Help

« on: 04 November 2010, 18:22:46 »

Also the flywheel to crank bolts are different too, the bolts for the dual mass appear to be 5-10mm longer than the solid flywheel ones.

So I've ordered some new ones from Vauxhall

The dual mass omega flywheel is and identical depth to the Vectra solid flywheel, the ring gear is identical too.

The friction plate is obviously different as the Omega one has no springs, and the Vectra one being a normal type friction plate does. The diameter is different too the vectra is 230mm the Omegas is 240mm. However the actual lining is the same thickness.

What effects the total thickness from the crank mounting face to the end of the fingers, is the fingers on the clutch cover. On the Omega the they sit much flater, but on the Vectra cover the fingers are more dome shaped.

Some pics.......







Here you can see the difference in design......


Oh and yes the input shaft for the FWD and RWD boxes is the same configuration 14 splines

Right I ordered a new dual mass and clutch though my work to compare to the Vectra Solid flywheel and clutch. It all seems spot on the only thing I'm worried about is the solid flywheel and clutch is actually 4mm taller than the dual mass and clutch.

I don't know wether or not that will be an issue or not! Guess I'll have to find out!

In at the deep end for my third post 

For what I'm using my Omega for I'm already experiencing problems with the standard DMF and clutch setup. When I kick the clutch or violently snatch up a gear the flywheel is over loaded and slips (originally I thought it maybe a knackered clutch, but I've done some research and it seems that the dual mass will slip when you try to overload the transmission, great if your driving Miss Daisy, not good for drifting)

Anyway is there an off-the-shelf solid flywheel conversion avaliable or is there a way to uses the cluch and solid flywheel from a Vectra V6 or Cavalier possibly? Or would a 3.0 omega DMF handle the abuse better? I did look into using a 4 pot flywheel but it appears the flywheel isn't thick enough and the release bearing my have a problem actuating the clutch?


Anyway any help or advice is welcome, Thanks Robin

that what you need for conversion

release bearings can stay from omega

I've got my hands on a Vectra V6 flywheel and clutch, so this should all fit with out modifing my standard Omega release bearing and the standard Omega starter motor will engage the solid flywheel?

Thanks again Robin

Thanks for the info guys, I was thinking of using the Vectra friction plate too as this has the dampening springs mounted in it. Atleast I know it's possible just need to get my hands on a V6 Vectra flywheel (that lightened one look cool but it's a bit expensive when you factor in a clutch on top of that, plus I'd rather keep low down torque at the expensive of throttle response).

Thanks again Robin

Thanks for the warm welcome

I imagine you'll be after an LSD then?

I'm not after an LSD lol, that's a bit posh for me. I removed the original diff and got a mate to weld it up. A welded diff is far more reliable and preditable than an LSD, plus it's cheaper and requires no special maintainance.

Hi I'm Robin, I've just brought an M-reg 2.5 manual Omega it's a clean straight car with FSH picked it up for £570 and tbh I'm really enjoying it.

Hope I don't get shot for this but I'm going to use it for Drifting (or trying to drift) I've owned several Sierras, an E30 and a Volvo 360 which I've all used for skidding. I just not a fan of Japanese car lol! Good to look at but painful on the wallet lol.

Thanks Robin
