yeah a fresh one comes with the new kit.

Its REAL tight in there, i used a combination of heating up the surrounding aluminium (dunno if that made it expand away from the sleeve thing, or clamp onto it tighter...) and thrashing it out with a well chosen drift. The thing is with the drifting it out plan is that you have to set the job up so that you can give it a f**king good smack and that all your hammer energy goes into the part you're trying to get out. If you're not working on a good solid bench top and don't have a way of keeping the clutch cover from jumping around when you hit it, then your life will be harder than it has to be. I started off tapping it like a girl because i wasn't sure how it was fixed into the clutch cover but once i was sure it was just a tight interference fit i gave it the brutality it deserved and out she popped.

To get the new one in, i actually put it in the freezer for half an hour to shrink it. When the time came, i heated up the clutch cover with my heat gun (a glorified hair drier if you've never used one), pulled the water pump sleeve thing out of the freezer and tapped it home with another well chosen drift. Whether the heating and cooling was worth the trouble i don't know but that whole carry on saw me to eventual success.
