clutch slipping

[fbssub1]

have a mate just put a new motor into his v2, skimmed the flywheel retired the old 225 clutch and brought a 230mm clutch and pressure plate, now he has a slipping clutch.

Now I thought 230mm clutch needed a different flywheel to the 225 clutch???? the only other thing I could think of is oil on the plate itself,

any ideas would be great

100% sure its the clutch?

a broken axle will give the same issue

(they can strip spines out - or just fracture at the end of the splines - the cv boot makes it all look ok and holds the axle up)

Silly question but did you wipe the pressure plate before install?

Could be unrelated but is it a shudder or more slip, mate had similar issue in his evo 7 turns out the garage he took it to re-used the old fly wheel and had it skimmed even though it had hot spots and a slight warp (he would have been more than happy for pay for a new flywheel).

So the car had a bad shudder, and on the garages advice he was told just to drive it and it would bed in. Long story short it toasted the new clutch kit and after MTA getting involved the garage had to pay for a new clutch kit and flywheel.

And according to some clutch specialists flywheels should never be skimmed, only ever ground.

pressure plate not set to correct clamp pressure .Always check or have it checked prior to install.

Autoclutch in Auckland requires flywheel,plate,pressure plate. Neill sets it you install and its guaranteed to work..Clamp force stated.

Brian this guys pressure plate could have been overpulled and now has f***all clamp.....Probably

Any chance if the clutch not being bed in yet? I heard it takes a while to bed in too. But slipping most probably pressure plate.
