Tein C spanners

Couple of questions:

 

1) The suspension looks very rusty and can see some damage to the alu seats(?) already, any tricks on getting these unfrozen?

 

2) Does anyone know where to get these? I've tried a few outlets but none stocked the adjustable ones Chris Wilson recommended in some old posts.

 

Ta :)

Yup me too. If the adjusters are corroded only brute force and ignorance or maybe a bit of heat will shift them. Dissimilar metal corrosion there. I tried to order new locking collars from Tein UK but they never got back to me.

 

Yeah, mine look corroded too. I'll give it a try but am a bit worried about snapping the collar (not seat as mentioned earlier!)

The chances are they'll be shagged if they've been on there any real length of time. Mine looked ok but were corroded on the thread interface - I guess there's some galvanic corrosion between the steel and the aluminium. One of mine had a hairline crack that ran axially like the sort you'd see on a pressure vessel or a split sausage under the grill! :D In my case the crack was a good indicator of internal pressue ............corrosion products building up in thread and "blowing" the spring seat open due to the extra material.

 

I bought four new spring seats and four new locking rings from Paul Whiffin and a new set of C spanners and replaced the whole lot as I didn't want to take any chances. You're welcome to the spanners but I wouldn't bet my house on being able to budge the rings - depends how old they are...If I remember rightly they're not expensive.

If they are the same as mine, the bottom, lone adjustable ring thingy is the ride height, the upper two that sit together are for the preload, and "aren't to be touched"! :search:

 

It's only the bottom ones I want to adjust. The car used to be a lot heavier so now looks like a monster truck :D

Thanks Dan, excellent advice :) You are probably right, they 'look' corroded and I don't fancy my chances of shifting them, but am considering giving it a go.

 

I'll contact Paul and see if he has replacements available. If they're sensible it should hopefully be a cheaper than replacing them!

 

General question - did everyone that had problems with them compress the springs before trying to adjust? I'd have assumed so, but just checking... Without compressing them I'd be putting an enormous strain on the collar.

I stripped the lot and took the springs off altogether as I knew I was going to be replacing the ali rings....the aluminimum rings might as well have been welded on for all the chance I had of budging them! :D 4" grinder and a cold chisel did the trick, then wire brushing (lots of) and then lots of copper grease and the newbies flew on a treat.

So whats the life on them then? If youre like me and never adjust them, when should I change the collars?

I think it depends on (off the top of my head):

- were they copper greased when last adjusted?

- do you drive the car much in the wet

- do you drive the car much in the winter (salt)

- is the car kept inside/outside (more temp changes/extremes if kept outside??)

Well greased would be the key to longer life. In my case the corrosion was internal between the aluminium and steel, it wasn't from general corrosion from any wet weather or salt. That certainly would not help though :)

 

Mine are Tein HA's by the way.

Mine have a 3/8th hole as well Jon...

 

Cheers. That would've been useful when I was trying to free them up a while ago, had to resort to other means... thankfully they weren't seized that time, just f' tight, but sod's law says they will be next time :taped:

Right, so considering the cars past (rather hard) life, I'll assume they're seized on like everything else so far :D Cheers for the input Dan :thumbs:

 

PM is sent to Paul, hopefully he can quote me happy when he's back from hols!

 

Edit - Just realised they are Tein HR, not HA, but doubt this makes any difference

I'm not sure that would make a huge difference, there's not much force there once they're just hanging :search:

 

edit: in other words, I don't bother compressing them :)

If they're still on the car (i.e. top mount still connected and bottom end still on the suspension) they still exert a huge force on the collar, was just curious if any of the problematic ones hadn't been compressed, but dandan blew that idea out :D
