-
- Do try to adjust the active region of the clutch: it should be possible.
-
- Can you see the thickness ofthe friction material of the clutch
- through an opening of the clutch housing?
- Compare it with the original thickness.
-
- Anyway, you should replace your clutch only when it starts to slip and
- is beyond adjustment.

- That should be enough. Get a lot of large wooden beams, and possibly another
- jack. Be at least with three persons!

-
- The lowering of the gearbox is not the main problem, getting it back in is.
-
- You must pay special attention to centering the clutch plate in the
- pressure group, but this surely mentioned in your Merc manual.
-
- Let someone rev the engine while you look at the center of the clutch
- plate, and center it as best as you can, _before_ tightening the pressure
- group bolts. When you put the gearbox back in, it might help to rev
- the engine very slowly for one or two revolutions. That just might pop
- the transmission aisle into place.
