Fitting Clutch Cable - Through Kidney Shaped Window

I have half told you about this, the early one has a nipple small enough to be pushed through the threaded adjuster, the later cable has the nipple larger and comes with the threaded adjuster captive on the cable, you need the right sized clevis for the nipple be it a large one or a small one, I am guessing that Paul H is trying to fit a later and much more common cable to an earlier style clevis, which would come with his kidney shaped cover, and anyway (rivet counters stop reading here) you bike Paul H is too young for a kidney shaped cover if we are talking the ex Hale, ex flying bogie, or is this another, if it is, then push on and get you kidney cover and cable working and stuff the R C's

I'm sure my SF1 came with a different nipple (and clevis) to the SF2, but I'm also sure it wasn't as small as that one pictured - I might have kept it, so can produce evidence! I changed to the SF2 one when I got a new clutch cable way back in history.

My understanding (talking to Wolfgang) is the very small nipple and clevis (as pictured) was only fitted to the early bikes which also had the flimsy Verlicchi levers (off scooters!!) which were quickly changed to Tomaselli (?) so most probably a couple of other sizes used later.
Anyway, something like that...................
 
Shape ya self its a clutch cable ,  and your in isolation, so you got ages yet , may be a full year to get it sorted 😜
 
cut a slot in the fucker and fit a Coxy stainless longer actuating arm poking out the top,
and just think what a joy that will be when the inevitable happens not even 1,000 miles later and the cable snaps, with you in a rainstorm and getting dark.

I have a spare kidney cover, and a spare coxy long lever, I could even get the slot properly machined for you, rather than badly done with a hacksaw and the waste material snapped off, without the sides even being parallel, like this one in my picture,awaiting repair when lockdown finishes, and yes, I will fill the round hole as well as the crack (to the left of the slot) I mean, with a longer arm there is no need for the hole, and the resultant weaker case cover is there, so why not?

cost would not be prohibitive and you would have the only kidney clutch cable orificed cover in the world WITH A SLOT

ps I wish that I had invested in a good TIG machine entirely for aluminium capability, the cost of more than a grand seems insignificant, now that both the local alloy welders are closed.

Hey Mystic Clem. Your crystal ball is half right. Yes, the kidney cover is going onto the Flying Bogie (late 71 SF), but it's just probably temporary and wasn't intended to go on that bike. A new front sprocket lead to the old (round hole and slotted for long actuation arm) cover being removed. I found it was goosed and pressed the kidney version into service:
? 4 out of 5 M6 female threads came out on the screws.
? None of the sealing faces were remotely flat or smooth.
? There are cracks emanating from the end of the cut-slot.

All easily recoverable, but I wanted a running bike asap. I know the kidney cover is too early for the bike, but I don't worry about that much. Best function is the way for me.

In addition, the aftermarket long actuator arm, though resplendent in sexy chrome plate, was made of too soft a material and the ball had dug in and spread the material out. The roller (reacts against the bottom of the actuation) arm was also completely worn out.

Oh they joys of Laverda ownership. Hag.

BTW - the end of the cable is the small type and correct size for the clevis retainer (both were from the SF and not donated with the kidney cover) Though it was a very 'near' fit. I made a little bent poker/proder from and old spoke to help me get it lined up and solve the fat-finger problem that lead to this thread. Something now essential for the traveling tool kit.

 
Paul, just in case you run into trouble when you replace the roller, I found that the one on my 3C was smaller than the 12mm replacement provided by Richard Slater.   

I also found that the perch that retains the smaller roller was a little different to that fitted to later triples, eg. an 80 Jota .   

Fitting the 12mm roller on the 3C perch resulted in insufficient clutch cable free play.

Not sure what others have done but  the slot in my cover for the longer arm (a foot brake lever cut and welded to the orig short lever) diesn't go to the bung hole. Sounds like some have cut the slot right into the hole. Never had any cracking probs and it was easy to get it straight - used a wide file to get the slot sides parallel and wide enough.
 
Thanks Tom, I didn't know that about the roller diameter. Mine was so utterly buggered I have no idea what diameter it started life as :-)  Luckily the kidney-cover came with perch and [short] lever in good shape, so I used those in the rebuild. I will watch out when rebuilding the worn stuff.

Another thing I found 'whilst in there' was that the eccentric stop for the gear change was a different diameter, older = smaller. I will start another thread about that - just for folk to refer to of they have a sloppy gear change.

This whole 'just a quick new sprocket' job became quite a saga. I even snapped the clutch push rod when trying to straighten it. Being hardened for full length, it snapped like a carrot.
