Title: clutch/pressure plate combo for 1200 bolted to IRS trans
Post by: Jeremy on December 21, 2010, 04:53:38 PM: So I've bought a running 1200cc engine to throw in the '59 to putt around in for now. (Emphasis on putt) The question I have is since I've converted it to IRS do I have to change the pressure plate and throw out bearing or can I bolt the engine right up and let er fly? (Other than using a 6v starter and a 12 generator and coil)

That ring comes out of most of the diaphram style PP's I've seen, it's a big flat pressed on circlip inside that has to come off, wear goggles while you pry as the clip shatters sometimes ;)

If you go this route you will also need to change the cross shaft! It makes it a little more work.

Post by: BUSDADDY on December 22, 2010, 10:20:20 AM: Oooops, Geoff's right, if you remove the sleeve and change the TO bearing the cross shaft is different too, the simple fix is pry the ring out of the PP and go for a drive :D
