I will try again to get pictures working, although I'm not sure how I'd photograph it anyway. Always difficult to photograph something that is not happening!

The thread on the tapered shank of the ball joint is a certain length X.
The top of the upright that the taper and thread go into is thickness Y.
After they are brought together there is some thread showing (X minus Y) so you put the castellated nut on it and do it up.
You do it up until it is tight and line up an opposing pair of the castellations in the nut with the hole in the thread on the balljoint / taper and put a split pin through to secure the nut.

However, after tightening the nut, it has not gone on to the male thread far enough for the hole to appear in any of the gaps in the castellations.
It appears that Y is thicker on the Mk2 than the Mk1.

I have ordered a pair of appropriately threaded nylocs (M12 x 1.25 pitch I think) so that will probably be the solution, assuming at least one thread will protrude from the nylon insert.

IVA MAN REALLY WANTS TO SEE A MINIMUM OF 3 THREADS COME THROUGH EVERY MAJOR COMPONENT NUT

Funnily enough I was cleaning down the now bare front subframe yesterday and found a barely legible label on the face where the chassis joins the subframe - i.e. the bit that is covered up once skate and chassis are assembled. The label is a reminder to fit a couple of nylocs to the top swivel! Full marks for the reminder. No marks for where it was positioned!

Hopefully a quickie.

Can anybody identify the manufacturer of this suspension unit?
It's a front unit and the only identifier on it that I can see is a number: 190005

I need a couple of spares for it and its partner.

Can't really tell but you probably won't want them on the Exocet anyway. They are likely either / both different in as much as they are probably lowering units AND will have the wrong compression in the damper and springs for the Exocet.
Remember the Exocet is now going to be about 700kg, not 1260kg

Those shocks does't look like that have been put together correctly I might be wrong without physically seeing them, but it looks like the bottom spring is trapped between the 2 plates which means it's not doing anything. If it is doing something then the middle black ring would have to slide up & down which will strip the threads of the body, all seems a bit weird

I have the Maxspeeding Rods Fleecebay specials, the springs are too hard & the ride on the road is crashy, lacks rebound, but they were £150 instead of £800 they've been on 3 years & currently for the mileage they do they are adequate, others will turn their nose up & sneer at them, but they've never used them. TBH if the springs were softer there'd be nothing wrong with them

[robski]

They aren't fully assembled as the top mounting plates have been removed and have gone for powder coating.
There are 2 springs, one with flat cross-section and the other round. There is a back-to-back seat between them. When assembled they both move in the correct sense.

The springs themselves are marked up as for an NB MX5. They came fitted to the car/project with top spacers between the units and the chassis so my guess is they were bought to lower the Mk2.5 donor and then jacked back up again. I expect they will be rather firm but I will run them with a low preload to compensate a little - if I use them.
Maybe getting lighter springs was one reason for finding out the manufacturer.

All part of the joy of buying an unfinished project.

I think these suspension units may be V-Maxx ones...

3 threads showing?
Don't they understand the concept of Nylocs?
There are normally a couple of threads INSIDE the nyloc insert anyway!
1 complete thread showing, i.e. excluding the lead-in, is acceptable for aviation use! My aircraft hasn't fallen apart yet!

That's what they want. I've had plenty of nylons work their way loose over time. Brushcutter had 4 m5's with nylons come off the other week. It all comes down to the tester on the day........................

That's what your tester wanted, unreasonable or not, were the ones on your brushcutter new or reused, they should never be reused

[hutchey]

Brushcutter ones were brand new as out the box and tightness checked beforehand.
Testers are testers - every one of them are different and interpret the iva differently. Makes a mockery of the whole thing really.
