It's pretty straight forward really , do you have a workshop manual ?
How much stuff is over the clutch housing (brake booster , radiator expansion tank etc ) ? You'll need to remove them all first , normally a brake booster you can move just enough to get the housing past it so don't stress too much .
First , chock the rear wheels and jack up the mini and put it on DECENT AXEL STANDS , not bricks . Remove earth wire from battery as you'll probably be using spanners near the starter solenoid if it's above the clutch housing . Undo the bolts from the drivers side engine mount , undo the earth strap from the clutch housing , take the clutch return spring off the clutch lever and undo the two bolts holding the clutch slave cylinder onto the engine (when you undo the bolts for the slave it will move back and the rod stays attached to the clutch arm so once the springs off you're set) . Undo all the 7/16th bolts around the face of the clutch housing (back ones about half way up can be a bitch to do ) , then jack the clutch end of the motor up slightly so there is room to pull the clutch cover off (bit of a wiggle and you're done , you'll figure it out) . Once you have the cover off and on the bench undo the two big nuts on the outside of the cover , then remove the pin holding the clutch arm to the housing and the clutch arm . Now the shaft that the bearing is on will slide out (towards the direction the clutch was when the cover wa on the car ) and you can take it to someone to get the old bearing pressed off and the new bearing pressed on . then reassemble it all (reverse of taking off) and adjust the clutch as per the manual (someone else can type that out
) .
Once you've done a few you can do them on the side of the road they are that easy , first time should only take a couple of hours to strip and reassemble , the longest time might be getting the old bearing off and new one pressed on .
