Hei trenger hjelp til å skifte clutch på en Fiat ducato bobil 2003 ..
Skulle gjerne ha hatt en bruker manual hvordan mån går fram..
Any questions please ask in English to help me.

But basically.
Support vehicle safely on stands after slackening wheel and hub nuts, then once supported off the ground the, wheels off, battery disconnected, release bottom ball joints, pull suspension out enough to release drive shafts from hubs, collect /drain gear oil, pull out drive shafts, reverse light wiring etc.
Next main problem depends on if clutch operation is pull or push type, on releasing clutch cable see if working the release arm moves the clutch bearing away from the clutch pressure plate, if it does , great , carry on removing bell housing and starter bolts and catch big heavy gearbox!!!
If clutch is a "pull" type the release bearing is attached to the clutch pressure plate which means gearbox cannot separate from engine until clutch pivot arm is removed.
There is a special tool for this which grips the circlip groove in top of shaft from memory which draws the pivot shaft out and releases the clutch bearing allowing removal of gearbox.
I note some one on Forum drilled a hole in bellhousing and punched the shaft out, not professional , but apparently did the job.
The one I did was many years ago on a Citroen Relay with Sofim 2.8 JTD engine and identical running gear and at the time the Citroen Dealers didn't even have that tool!
With the customer/owners permission and as I was replacing the worn clutch assembly completely, I used a large crowbar to force the clutch bearing from the clutch pressure plate allowing removal without damage apart from to old clutch assembly, but it was hard work on my own outside the customers warehouse in a snow storm, so not something to be repeated, I was in my late 50s even then!!!
You may be able to check through inspection hole by release arm to see if it is that type, or inspect the new clutch kit operation.
Incidentally when clutch all assembled and gearbox fitted , with the "pull " type clutch you have to firmly push the release arm forward to install into clutch pressure plate or it will not function.
There is a slim chance yours has either a hydraulic clutch or a standard "push" type release mechanism, if so the job will be much easier.
Others on Forum will be able to identify your clutch/gearbox type.
Note this is the "pull" type I am referring to, see the strange end to release bearing and corresponding arrangement at the clutch pressure plate.
