I cant get the actuator levell ball reach the rod to engage the clutch. The rod is sticking out 10mm, is that correct ?
Can it bee that the ball inside the rod is missing?

can easily be the case (not only missing, it can melt when you hold clutch at traffic lights for to long or when decellerating, when on a dynojet to test power etc. etc. etc - happened to me several times... can also be the square on the other side sitting inside the clutch is "drilled" by the other rod, so that the rod sits deeper inside the square metal

Best way to find out is to take the rod out, take magnet on a stick like these below and pull out the rest. This way, you do not have to take the clutch side appart at the first place. check the lengths with Laverda-Paradies webpage and see if they are still long enough. The ball is from a bearing, can be bought separately if missing...

Thanks but what do you mean with " magnet on a stick like these below" ?
 
sorry - forgott the link...

The magnet of this one is small enough to reach into the mainshaft and "grap" the ball/rod inside the mainshaft and drag it out. You might need to remove the oil-seal sitting in the end of the mainshaft. easy if you do it after you pulled the first rod out.

Thanks.
Looking inside the "hole" seems like the ball are missing, the end I can see looks like a rod. What dimension is the ball inside?
Both balls have different partnumber ?
 
Typing "clutch pushrod" into the 'Search' box (top right) reveals this, which may be of help.

 
I do not know why, my memory is not good, but there is a strong indication coming from deep within my own grey matter, that those balls are an imperial size, so be careful, hopefully a professional will see this and add a comment. Not everything, written, posted, online, manuals, or otherwise is accurate, far from it. More than happy to be the one with the duff gen here!

That link refers to an RGS . I have an 750SF 1973. Are they the same?
Yes

Andy Wagner lists the pushrod length as 112.5mm

11mm is the usual protrusion of the clutch operating rod from the mainshaft. So 10mm should be enough for the clutch to start lifting. Are you sure you have assembled the operating lever assembly in the outer cover correctly? The arm position can slip when you offer the cover up to the engine.

Manage to get the rod out with help of a 6mm plastic tub connected to a vacuum cleaner :)
No ball there.
Had to destroy the sealing to get i out.
Anybody know spec dimension of this.
Shall I just get a new ball or shall I go for the long rod ?
 
Thank Paul.
Lots of speaking about the O-rings , washers and shims .
I got my bike partly in parts so I am not sure about the order of placeing those.
Is it just to follow thw drawigs
Oil seal is 6 x 19 x 7
There's a 750 parts list available for download page 4 of the library of this forum. Use it for rebuilding.
If you have any doubts, ask here on this forum. You'll get plenty of answers, some will be correct.

Respect strictly the lengths of the clutch push rods and the size of the balls.

The ball acts as a kind of bearing, separating the clutch drum speed (which is transfered to the inner push rod via the square block inside of the clutch) from the gearbox mainshaft speed. It is a necessary part and should be there.
 
Thanks everybody. I´ll sure be back consulting your knowledge.
Wish you all a Happy new Year and myself celebrating my 70 years anniversary🥂
 
Clutch pushrod ball is 1/4 inch - been discussed on here before (recently). And I'm almost positive the one in the cover is 1/4 inch also - 8mm sounds very odd to me, but happy to be corrected. Not at home (at a beach house) so can't check.

Piet?!!
