Anyone got a tutorial or some good pointers on fiting of a clutch.
Ive got a new sach clutch, m20 fly, 323 release bearing and spigot bearing (i think) all for my m42 box.
Never fitted one before so not really got much of an idea what exactly needs to be done to fit it, any special tools needed, what sort of prep needs to be done etc?
Fitting clutch

Fitting the flywheel is easy enough; just make sure you use new flywheel bolts, torqued appropriately and don”˜t forget the load spreader!
Only thing you might need for the clutch is a clutch alignment tool - although most people say an appropriately - sized socket with some tape will do the job, the tool is about £15 from Machine Mart - not expensive. Pick an appropriately sized bit for the alignment tool to fit into the spicot bearing in the crank, then slide on a tapered bit that fits the hole in the centre of the friction plate. Slide the friction plate onto the tool, then align the pressure plate with the flywheel - it only fits one way, there are alignment dowels for this purpose. Use new pressure plate screws and ensure they are torqued to spec, remove the alignment tool, job done!
If I”˜ve forgotten something or gotten something wrong I apologise...

This, catching a stay flywheel is no fun.
Clutch aligning tool will save a lot of hassle.
The bolts on some clutches are 6mm cap head allen key bolts, use a socked allen key for these as they are easy to round off.
Spiggot bearing is a bit tricky to get out but I have a trick for them:
Get some wet toilet paper and stuff it through the centre hole, pack it in with a bar roughly the same size as the hole in the bearing, repeat, keep going until you have to start hitting the bar with a hammer, then keep going more.
As you stuff it in and pack it down it deforms and pushes up/out on the bearing, keep going and you will essentially jack the bearing out, it puts uniform pressure all around the bearing and essentially extrudes the paper until the bearing is pushed out.
When the bearing is out you can just flick the paper out with a screwdriver and then wipedown/spray down the area.
Some people do a similar thing with grease but its much more messy, you cop a face full of it half the time and it won't move stubborn ones.

Forgot about changing the spigot bearing! I used the E36 ZF 'box so didn't need to do this. You will if you're using the M42 'boxHairyScreech wrote:

Thanks for the replies lads, so it's not the biggest of undertakings then! For the sake of a few quid is it worth investing in the tool?
I've not new bolts and the load spreader waiting to go on, I need to check to make sure but I think I also have alan headed bolts for the plate (maybe they came with the clutch).
