Re: Leaking Clutch Oil Seal

Hi Terry, yes indeed it can be frustrating, but I've managed to resolve this. Primarily, you need to remove the whole clutch casing, and replace the main seal 'on the bench' rather than in situ. Paul Compton has an excellent series of videos on this on YouTube, well worth following (to the letter!)
I used a double lipped viton seal from Simply Bearings (UK) costing around £10. I don't believe that you can replace this seal in any other way - I've tried to do it in situ without success (see my postings earlier in this thread). When replacing the casing, I used 3M flexible masking tape to make 'taper sleeves' on the camshaft and clutch mainshaft to guide their seals into place, and it worked fine. Remember to use plenty of lubricant! Clutch housing seal should be fitted dry (no Hylomar) and remember to clean the locator dowels scrupulously. It's not as difficult as it sounds, so go for it. PS it's worth having a clutch holding tool made up by welding a couple of old clutch plates to a handle. A local machine shop made mine up for £15. Please keep us posted, best of luck!
