I had to go the custom one off way. Stupid expensive. Any good machinist can do the work...if you are working with a shop they will know a good one. Make sure they use high quality steel...we used a form of tool steel.
Very useful thread. My caps are all odd walled and one had been dropped and the thread damaged, quick tickle with a needle file solved potential cross threading. Why the locktight and high torque when other top mounts don't use them? All parts now sourced hope ToSi can get those shouldernuts made. I confirmed with Rennline that theirs are for KW shocks. First I need to fit the Elephant bushes should keep me busy for a while
great thread Tosi .. thanks for the clarity ... just wondering what is the function of the #1 covering nut?
Just for dust in the monoball? seems very sturdy for that alone.
In a couple of mounts I am going to upgrade the top mounts on my silver 993, associated with PSS10.
Is there anyone who has machined produced two of those spacer/nut for the top mounts or any address when I can find it already done?
And if not, if I got it right, this spacer/nut machined from full, is the extension of the shock absorber rod, so it is supposed to be very strong material: what kind of steel should I use?
I just don't understand why the outer diameter of the ToSi nut has two sizes, while the seat of the RS top mount is perfectly cilindric with just one diameter. Is there a specific reason?
The Tosi nuts are in production at machining shop, a little bit modified.
ToSi was very kind and helpful, answering my doubt and giving me support in the changes I decided to introduce to his nuts.
Once I get them I am going to expose the changes
but for now I have a question: this sealing black strip, no one here removed it?
this 3/4mm thick layer...I mean...I install a mono ball to avoid any gummy interaction, but then, between the coil over system and the body this black layer isn’t going to reintroduce some kind of imprecision?
Probably tightening the 3 nuts the thickness of the black gummy layer decreases, I was also thinking that this layer probably works more as a vibration damper, because when the nuts are tightened, there is not very much more possibility of deformation for the black gummy.
in any case it is fixed using 3 and not 4 nuts, so probably it can move a bit around the single nut changing the angle of the coil over.
i am just asking myself if there is some kind of reason why they built it this way
