speedometer and rpm cables

Thanks Piet and Paul M, I haven't checked what you say but I will go for 15mm hex on the cable, in recent years I have taken to using a very small but really well made Bahco adjustable spanner every time I need to disconnect, saves me a lot of fiddling and remembering if its 15 or 16 (which it isn't)

The reality is that when removing the front wheel, I no longer bother unscrewing the cable at all, just swing the gearbox aside on the still tightened  up cable.

These aftermarket parts that don't fit were getting much better a few years ago, now they seem (to me) to be in decline, and with most consumables being in this category, what are we supposed to do? NOS consumable are virtually gone, and behind that non Laverda specific parts are drying up as well (Brembo, Marzochi, Ceriani, Bosh etc) and they also being produced now in crap quality (not always)
It is a joy when using something that Laverda actually made themselves that is new old stock, such as a few gearbox parts recently.
CLEM
ps, someone is going to chip in any moment and say that gearbox parts were a subcontract, I guess.

I'm very much afraid Clem that I believe that it's a question of demand and that is falling sharply I should think due to the bikes not being used as intended.

In order for a speedometer or rev counter to last a long time, the following should be observed:

- The devices must no longer stand on the glass (e.g. as a spare part), otherwise the damping = silicone oil will leak and you will get a nervous pointer!

- The square for the drive must not protrude beyond the edge of the sleeve than specified (see picture).
  Otherwise the bearing will be pushed up and the speedometer / tachometer will be damaged.

- All drive shafts should run without kinks.

- Occasionally lubricate the shaft with some non-resinous oil.

Yes well, I made the assumption that must be something similar, because now I have in the instrument side just 3/4 mm as the veglia and doesn?t work, so must be the other?🤷🏼‍♂️
Anyway, I found a place on the island where they prepare the taxi computers, trafitionally they did a lot with those sort of cables and they have a lot of stock, they will make a new inner cable with a very long square part, that I can cut, I will see how long does come in and take 2 mm less, to be sure is not pushing, and that should work I guess🤪
Or wait for the new cable from Wolfang hoping it has the right length...

great stuff Thomas aus LAU
interesting that the Jaeger looks to be imperial threads and the Smiths metric (contradicts you Piet) and I thought Jaeger was English, had many Jaguars over the years and 60 and 70's cars had Jaeger for the main big instruments, Smiths for the remainder..

what we would really like is factory drawings that show the whole cable of all types that would be ideal and is probably in a box in the Barber Museum, Birmingham, Alabama, USA. These drawings would have been needed to send out to suppliers for quotations. I have a few factory drawings (Chott cables etc) so assume they did at least at one time exist.

it would be nice if people could upload all the drawings they have so we could all use them. Its hard  to come by those sorts of things
 
This sort of info is freely available from various specialists on the www, just need to do a bit of research.  Many instruments specialists clearly outline fitting instructions for cables.  Obviously, they want to avoid unnecessary warranty claims.

Jaeger was based in Paris, joint-ventured with swiss watch manufacturer Le-Coultre at the beginning of the 20th. century.  Later became known as Jaeger-Le Coultre.  Smiths aquired the UK subsidary Ed.Jaeger (London) Ltd. in 1927, which then became the British Jaeger Instrument Company.  (Also from the www, Wikipedia)  So, half-points to you, Clem.

I hear you on some info being about.
Im more interested in laverda parts drawings with dimensions. Seems sensible to have that about for those of us that have the contacts or ability to make things. Kind of like a little open source file for us to make parts from
 
I will go with you there Piet,

but at our next meeting you will have to go halves on the first beers and I will go halves on the second, that should sort it.
Maybe Breganze 2021, if we are clear of Covid, I doubt it.

Don't forget that you are always welcome here just 20 miles South of London, I hour from Dover, if you are ever travelling this way, beer in fridge, bed made ready.

These museums probably get factory drawings thrown in with job lots they buy and would most likely want to get a return on them. Are any of them charities that are interested in helping owners clubs?
