If you want a 1500 flywheel, I have a freebie in Brighton.

Great News! After Clive very generously donated a flywheel from a Spit 1500, along with the clutch cover and bolts, I was able to source a 190mm 1", 23-spline driven plate, for £55 delivered, from this guy, Neil McCarty, who I found on the Facebook group "Type 9 Gearbox World" (who knew there was a whole Facebook group dedicated to just this gearbox?!) 

After an epic job of replacing the gearbox, which after about 6 hours I realised I ultimately had to remove the inlet/outlet manifold as it was stopping the input shaft aligning with the cam shaft spigot bearing (in fact it wouldn't even go through the hole in the clutch cover finger plate) I now have a mobile car again. A couple of minor issues to fix, such as the speedo not working, so I must have made a mistake connecting the cable in the gearbox drive but altogether very happy.

Thanks again Clive and thanks Neil McCarty, if you're out there

The parts needed are:

Second hand Spitfire/ MG Midget 1500 flywheel. 

Flywheel bolt spacers, Paddocks have them in stock & are half the price of Canleys. https://www.jamespaddock.co.uk/flywheel-spacer-bush-2

Spitfire 1500 clutch kit (you only need the pressure plate & release bearing from the kit). https://www.jamespaddock.co.uk/clutch-assembly-1500-2

1600 Sierra clutch friction plate. https://m.buycarparts.co.uk/aisin/299946

 

Many thanks Amy, however that clutch plate only has 20 teeth whereas the Type 9 has 23 teeth

Yes please

If the 23 splines are same as 1500 dolomite splines, there is a 23-spline small plate fitted to a Triumoh, possibly later Toledo or 1300 Dolomite. I think.

You're saying I may probably need to buy a 'plate'? To fit where exactly, please?

Yes. True. This is why the Canley text copied further up this thread mentions flywheel bolt adapters - just four little collars to increase bolt ID at the critical point - to get around this. The actual location/centralisation is done by a dowel and the lip on the back of the flywheel so this is less flakey than it sounds.  Torque is transmitted by the clamping friction, not the bolts…..
 

I remember creating some adapters to match a 1500 flywheel to my Herald 1200 engine out of a piece of random steel pipe that happened to have the right diameters. I still have my feet….

I've checked the Canley parts list and the drive plate is N/A so not sure where I get the correct one

Yes I wonder if that clutch could even go again if the operation of the thrust bearing could be corrected? Alright as Clive says the friction plate has only got 4 out of 6 torque springs but I think it must have been custom made like that and maybe isnt a problem - it would certainly save a lot of expense and/or work if reusable....

It definitely wasn't made like that as I retreived a load of broken bits of spring when I removed it

That looks like it is the "custom supplied" clutch plate. No idea who sells them, but Frontline were the people supplying kits, so may be able to help.

The better idea may well be to use the larger clutch/1500 flywheel. Proably the cheaper option too. Besides, the plate you have looks as if it has lost springs? But appears to have plenty of friction material. And the cover has odd wear marks on the fingers, as if the bearing has been rubbing halfway down them. Wear is usually at the tips.

I think the 1500 flywheel uses 7/16 bolts to bolt to the crankshaft but my original uses 3/8 so would this mean the holes in the 1500 would be too big and hence would be problematic to centralise?

No, it indicates that the person doing the conversion had to decide between two routes - one very expensive and problematic, the other simple but needing some effort in the conversion. So what you need to do is find out what flywheel you have fitted.

Take the gearbox out, photograph the clutch/flywheel and post the picture here. Somebody will answer that question very quickly. The 1500 flywheel has a ridge for the clutch cover fixings, the 1147 (and 1300) are flat.

Well it has been a long time coming but I finally managed to get the gearbox out and remove the clutch. It appears to be a 23spline version with a 6.5"pressure plate. Photographs attached. If anybody could advise where I can buy the respective parts Or which parts I need to be looking for it would be greatly appreciated

Thanks for the quick reply Rob. When I get I manage to get the gearbox out I'll do as you say 

Hi Guys,

I have a spitfire4 Mk2 1147cc in which the previous owner installed a Ford Sierra Type 9 5 speed gearbox, which I understand was/is a popular conversion. My problem is that the clutch has now gone so does anyone know if I can simply buy a standard mk2 Spit clutch or is there something else I need to buy. The Canley website, as attached, indicates I have to do something else but they have nothing available to buy. Any help greatly appreciated :)
