I have just fitted a heavy duty valeo clutch to my 300tdi 90. So far I have always fitted standard Borg & Beck clutches but they don't last very long so this time i went for the HD one. to my chagrin, if i put my foot down, the bugger slips. So I pulled the engine out yet again (a day after I had put the whole darn thing together) and could find nothing wrong. I work in a machine shop and my boss told me to bring the flywheel in for a skim. Am I right in believing that since the Vaelo clutch plate is approx 6mm larger in diameter than the standard plate, the edge of the clutch plate is touching an area of the flywheel that has never had a clutch rub against it and is not finding a smooth surface?
not noticeable to me. obviously there's the shiny bit where the clutch rubs and the non-shiny bit where a clutch never rubbed

I run the 130 valeo clutch in mine and have done for years now (several clutches not the same one). The advice I received when first fitting was to skim the fly wheel as it is a larger diameter but I didn't bother. If it is still slipping after the skim I would suggest there is a problem with either the hydraulics hanging up or the spring plate is warped and not holding it in place properly.
