Hi Guys

Can anyone shed some light please, I’ve got a Vauxhall Omega Estate 2.5TD, it’s the one with the 6 cylinder BMW lump in it.
I’m guessing the fit may be the same as petrol Omega’s as far as the air con is concerned.

Right, the clutch has fallen off the air con compressor, luckily I did not loose it however the fixing screw and I assume spacer washer have gone missing, no doubt dropped off along the road somewhere.
The only thing I can’t figure out is how the darn thing screws onto the air con compressor shaft.
I can see an M6 tapped hole in the shaft and tried putting a screw in it but when tightened it locks the whole thing up in other words it clamps the clutch hard against the rotating pulley meaning the compressor is running all the time the engine is running irrespective if the air con is switched on or not.
I also noticed the clutch has an M8 tapped hole in the middle of it, does anyone out there know what the fixing screw looks like and the spacer washer thickness.

Thanks to anyone who can sort me out.

Sounds like you're missing alot more than a bolt and washer 

I would probably source another compressor tbh.

Hi Doctor Gollum

Thanks for your reply, Iv'e watched one or two youtube videos and most of the clutches are simply held on by a big screw with a spacer washer, I just wish I could get hold of an exploded view of the omega set up.
I don't want to go to the trouble of buying the complete compressor for such a small item.

Does it look like this...

Shop around, but you will be able to get a spares condenser for alot less hassle than the individual parts...

Late to this as away for the weekend .. don't know if this helps or hinders ....

 Do you have a facelift car or pre facelift?
Pumps are different on the 2.5TD for these
Facelift is a three bolt fixing
If I still have it, I have a pre facelift ac compressor

I did the sketch but had the headache of finding a website where I could upload the photos for free, I did use Photobucket which is no longer free and photos that have been posted on forums through them are no longer visible, what a bind that is.

I have tried a couple of breakers one being called breakersyard.com without much success, I was thinking these Omegas are getting that old now especially the diesel I’ll be lucky to find anything.

So, I got to thinking why buy a compressor if it’s just a simple thing like a screw and spacer which has gone missing.

I’ve got to say to everyone on here who replied, I have just seen the light how stupid can one be.
I’ve just been watching a youtube video only to discover it’s not the whole clutch which slides along the splines of the shaft as I thought, heaven knows where I got that idea from.
I wear varifocals so if anyone asks why I thought that I’m going to swear blind I was looking through the wrong part of the lenses lol.

The one part of the clutch doesn’t move at all, it’s just the outer part that does all the moving in and out towards the driven pulley.

I’ve just run another check on the compressor with it off the car only to find clutch is not moving, when I connected some jumper leads from a battery onto the two pins of the plug it arched as though there was some kind of short, so I’ve done a resistance test with a multimeter and came up with a reading of 0.8 ohms.
I’m guessing that’s bad news because on a couple of American cars on youtube they are talking about the resistance should be between 3 to 5 ohms.

Maybe it would be cheaper just to simple ride around with windows open if its too hot inside the car.

Iv'e got the facelift model year 2000 so I'm not sure if what you have will fit mine unless someone can advise otherwise.

Sorry about the one photo fellas I'm still trying to get use to uploading images

In your other thread, (I did ask admins to merge them to no avail), I have linked to a couple...

Steve at Omegaspareparts has one in stock as well... Which will be a working one.

[Keith ABS]

 No, the one I have is for a preface lift model.
I bought for my facelift car not knowing there was a difference.
My front pulley came off at 60 mph, went through the fan cowl, smashed up the blades, three of which came up through the bonnet. The rest wiped out all hoses across the front of the engine
and bent the viscous coupling, and put a hole in the radiator almost 2 inches in diameter.
Had to stop then

Hello Keith

Thank heavens it didn't do a lot of damage lol.
Have you fixed it all yet or got rid of it.
