double check you have all the bolts out ,its easy to miss one
if you are SURE they are all out give the casing a good tap or 2 with a rubber / plastic mallet , if you don't have one use a wooden block or the handle of your hammer , sometimes the casings can be quite tight to get off.
good luck.

Hi

As above, but you will probably find there there are a couple of locating dowels on the casing so it probably has to come straight off rather than be knocked downwards.

All the best

Just as BlackSheep and Kickstart said.

But, if there is a cork or (more likely) a paper gasket in place and you damage it getting the cover off, then have a tube of silicone sealant to hand.

If you damage the gasket do not re-use it, or you'll just have oil pissing out all over the place when you start the engine. To be honest, you shouldn't really re-use ANY type of gasket once it's been removed. It's a complicated explanation, so I ain't gonna bother

Scrape off all the remains of the old gasket material from both surfaces to get back to bare metal. When you're ready to refit the cover wipe both surfaces clean, run a bead of silicone sealant around ONE surface only - probably best to do this to the clutch cover, since you'll be able to lie it flat down.

Then, using your finger, smear a very thin coating of oil on the engine side of the clutch housing. Why? Because if you have to remove the cover again, this smear of oil will prevent the silicone from bonding both surfaces together, which makes it much easier to remove the cover again at a later date.

Allow the silicone to skin over and harden slightly, so that it has a rubbery feel to it. DO NOT refit the cover whilst the silicone is still soft, otherwise it'll just 'ooze' out of the joint and do nothing whatsoever.

Once the silicone has begun to harden, refit the clutch housing and only tighten the bolts to the manufacturers torque setting. It's so easy to over-tighten bolts. Don't forget, you're only producing an oil-tight, medium pressure seal, you're not bolting the head to the block or the engine to the frame

Hope this helps.
