I see 3 varieties of alignment tools on the web. One, like I have aligns friction plate with pressure plate, no good. No. 2 is a box of 17 bits, a holding rod and an assortment of sleeves to fit to it; might do, if the 2 vital bits are there. No. 3 is a shaft with tapered handle centre, and again some sleeves. Again, few list sizes on the web.

I see Haynes says it can be done with a screwdriver thrust through the friction plate into the spigot bearing with tape wrapped around the shaft to fill out the spline hole in the FP. Lots of scope here for improvisation. Thanks for suggestions chaps.

If ID of spigot bearing is really 15mm I have lots of copper pipe like that . .

Grubbing around in my plumbing drawer, I have found a 15mm to 22mm  copper adapter that slips smoothly into the centre of the splines. I think I have my alignment tool.

The kit I have has a selection of fittings that screw to the end of the alignment tool and fit inside the spigot bearing, there is then a second piece that slides onto the shaft of the alignment tool which sits inside the friction pate splines.  :y

There are suitable bits for the Omega setup in the kit

Have you confirmed that you have the correct clutch? Either side by side with the old one or on the input shaft...

Also, any lip on the flywheel face? If so, the clutch won't sit flush, then the pressure plate won't bolt up true, and the whole think will jam solid.

Everything off, find a suitable socket to fit the hole on the end of the crank. Offer clutch up, position approximately central, but certainly within the recess of the flywheel. Then locate pressure plate on its dowels and get the bolts started...

Insert socket with long extension and you should be able to tweak the clutch plate as required.

Once satisfied it's central, nip up the pressure plate bolts in an even fashion, quick double check of the clutch plate position and torque the bolts up.

Make sure the box is in gear and offer it up, rocking the output shaft until it catches, the shove the box home onto its dowels and get the rear mounting bolts started.

Have a well earned cuppa and get the rest bolted up :y

If you have tried all types pf alignment tools then as suggested i would make sure that you have the correct clutch by comparing it to the new one and making sure they are identical...other than that as long as you make sure the box is straight inline when offering it up and give the box a good old wiggle / rotate by rights it should go in... :-\

Fitted my clutch last week and as AL says I used the 13mm deep socket on a extension. Found the spline and the shaft stuck and wouldn't slide together. I put it in gear and turned the flange on final drive side. Slid home no probs after that

Thanks to all for advice and encouragement. I don't know what is wrong with me, I spent the weekend failing to attach gearbox to engine, like men have been doing for over a hundred years. May have been mislignment of friction plate with spigot bearing, may have been misalignment g'b to engine. Monday I lugged car out of garage and parked it outside in the rain while I mended other cars. I shall try again next week, with Marks' alignment kit and some stud to assist me.

Next weekend is listed as family birthday bonanza, all ranks (and Omegas) will be home to celebrate 3 birthdays, so no work on cars then. Big birthday for me was last Sunday when grandson Tom was one.

Reassembling the gear linkage. On strip down I found an orange washer below the plate and above the link pin (see pic). It seems to have no function there. Should it be above the plate?

Possibly part of the support bearing in the lever mounting :-\

How was the gear change before? Any horrific slop?

Gear change was fine before dismantling.

On the pics I took when I changed the clutch on my 3.2 January 2014 the orange washer was above the plate. It makes more sense there, that's where I shall put it. I conclude this car has already had one new clutch.

I didn't leave it attached the first time, I think I might have followed the instructions in the book of lies Haynes manual  ::)

I didn't make that mistake the second time  ;)
