anti roll bar nuts(castle?)

[n/a]

Hi all, I have just put the U.S Import (280sl) in for it's M.O.T
Here in the U.K and it failed on lights which I've ordered no problem.
But the car also failed on the anti roll bar retaining nuts. the
type on the car are castle type which should have a split pin through
the bolt but the bolts did not have the holes drilled through them.
I wanted to get new type nylock ones but can't find anyone
who does them. Do I drill the bolts for the castle nuts and keep
it correct or keep looking for nylock nuts? HELP?

Red,

Nylock nuts--nuts with a crimped-in nylon locking washer--should be relatively easy to find.  You should be able to find them at nearly any fastener supply house.  Try http://www.workshopsupplies.co.uk for example, but you might find a local supplier...

Either the castle style nuts or the nylocks should work well, as nylocks are often used in this application.  Castle nuts
are not too common anymore--too much effort to install and remove.  However, if you don't have the holes in the bolts, that should be a flag that you don't have the right bolts in there.  Believe it or not bolts come in many grades, and you might be doing yourself a disservice without the correct bolts in there.

Cheers and good luck.

BTW no state or federal inspection in the USA would go as far as looking at nuts on a sway bar...

Red can you define M.O.T.

I may be wrong about this, but about two years ago I took off the sway bar to fit polyurethane bushings, and I don't recall seeing either castle OR nyloc nuts. Again I may be wrong, can someone else confirm whether these nuts should in fact be castle or nyloc?

FWIW, the BBB shows the sway bar link bolt with two nuts on the end (jammed together), figure 32-8/4 in the version covering cars from 1966 to 1973.

For those of you who don't have much mechanical experience, there are generally three ways of preventing a nut from coming loose.  The most obvious is a lock washer--either split ring or toothed.  Second is a Nylock nut, which in effect has a built in lock washer, albeit nylon, and lastly is a jam-nut where you have one nut jammed up against the other.  In heavy duty applications at my car wash, where we have threaded rod holding much weight into a masonry wall, we use jam nuts.  On equipment, usually lock nuts.  Less costly on mass produced items is the Nylock since it is only one piece to put in.

It is quite interesting to me to see all three of these employed in our short "Tour de Sway Bars"!

I removed my 280SL's front sway bar brackets this past weekend while performing a subframe mount replacement.  The bracket nuts (those that attach to the longitudinal subframe leaf spring bolts) definitely had split lock washers as the locking mechanism.  I retained these and torqued the nuts to their ~ 120 N-m spec.

I don't recall what my vehicle has for the sway bar link nuts but jam nuts are a common locking mechanism for this application.  I would think that a castle nut’s cotter pin would be too prone to damage from the links’ low-lying position.

Hello Hauser,
 your question about M.O.T. It's a test for all vehicles which are
over three years old, the standard which is set each year by year and revised depending on what accidents happens on our roads here in the
U.K, by the Ministry of Transport, hence the name M.O.T station
and M.O.T test certificate. which is needed over here to get a tax disc the same as your tags or plates.

And I say it's a good thing. I don't want anybody inspecting my nuts.   :twisted:

Just a Thanks To all for advice, Problem is now fixed I got some
nylock nuts for the rollbar in a scrapyard, off a peugeot 306
shockdamper 14 metric fine with 1.5 pitch 22mm accross the flat.
 To all try not to snap off any nuts or bolts as there getting hard to find.

Well , here's another quiz for you experts out there.
The castle nuts are wrong for the sway bar. They may have come from another part of the car. Where?

Seems to me the castle nuts belong on the bottom of the kingpin assembly; not on the sway bar...

Red,

Tell me it ain't so.  You got U S E D Nylocks?  From a Peugeot no less?  These should NOT be that hard to find anywhere!  They are as common as a cold wind in November.  They cost less then the petrol it took for you to drive to the scrap yard...and the more you remove and replace Nylocks, the less the nylon's holding power...In the upcoming election, I vote for new nuts.

Now if you were working on a 1958 Triumph and needed WHITWORTH Nylocks, I'd be more forgiving.

Ok. Just to make sure, are you talking about the nuts on the link pins or the ones under the straps which are quite a bit larger? Niether of them have castle nuts although the one on the king pin does as well as the lower pivot bolt.

Hi Mdsalemi,
 I only used ones from scrapyard till the new ones I have ordered
arrive, Thanks for the posts but I tried 68 places here in the U.K
one place in paris,France and OZ they were all (nuts) and bolts
outlets, I also went to truck builders Renault in Wales about 23miles
away and they all were very helpful but with no joy, this is not an
easy thing to order overhere I don't know why, it look a standard nut
to me also. The four New 22mm nuts are costing about $20.00 so not
cheap anyway the only reason for my panic was when a car has an M.O.T
test the items it fails on must be corrected within 14 days or you get charged the full retest fee about $46.00 and they check everything
all over again, but if you bring in it in within the 14days limet they only test it on the things it failed on or didn't comply with
like the sway bar nuts. So what did the castle nuts come off? this
is a more important question! also the M.O.T test guy found the castle
nut on the steering box didn't have a split pin in either, thats now
corrected so is the sway bar and the car now has it's 12month M.O.T
and when the new nuts arrive I WILL put them on.

red kelly,
Next time try using your local MB dealer. They're not all as bad as cracked up to be, and common or garden parts are reasonable priced + they are the correct tensile strength.
