Have you fitted a new pressure plate? If you have, you may have forgotten to remove the hooks that keeps the fingers down for transport purposes. When you fitted new plates, have you turned them the right way around? That is the marking "flywheel side" to the front. By the way, I think that you can change (get) all gears but the tractor will not drive (move).

It maybe, if you have not had the tractor that long, that the previous owner has moved the pedal in relation to the cross shaft to allow for pedal adjustment as the clutch wore.

You can't move the pedal on the shaft on an 880, only on the 770,780 and early 885.

Ollek the pressure plates are fine, only replaced the plates as they were contaminated with oil and looking slightly worn, PRs is right you cannot turn the shaft as they are milled in the centre only allowing the movement of the cross shaft to be removed from the housing,the plates are in the correct orientation but I cant fathom out why I still have the gap between thrust bearing and race???

There are two types of clutch pressure plates, live drive and non live drive, as I found out when I could not get a pedal. Studied the diagrams of the clutch long and hard before it was obviously the wrong plate supplied.???

Another thing to check is the position of the eccentric pin that holds the roller, the part with the series of holes on the outside below the clutch pedal.

Well I've found the problem fellas, the circlip which holds the driven shaft in the gearbox had slipped out of bed resulting in the driven shaft going back into the gearbox when the two halfs of the tractor have come together when aligning the clutch,
job done little 880 can have its first showing this weekend at chipping steam fair with its stable mate and best buddy 900... :D
