Alternative to obsolete pivot bolt?

#1 Post by MarkVeryard »

Hi Folks,

Have been stripping my front suspension today so that I can re-bush it - but the damn pivot bolt that connects the lower wishbone to the mounting bracket was stuck fast so I had to cut it off.

Trouble is that Rimmers list this part as 'no longer available' (part 216901) - does anyone know there I can get one, or whether there is a suitable alternative? (or is there something special about this bolt?)

My best guess so far: the front shock absorber lower mounting bolts seem similar (BH606201) but would need the threaded length extending.

Any advice from the gurus?

Cheers,
Mark.

You mean that really long one? I soaked it in wd 40 for a week (more WD every evening) then used a 2' breaker bar on one end, and the other end a large ratchet wedged under the subframe. I think I only had to jump on it a few times before it came loose...

I'd quite like to renew mine if a supplier does come up, I can't think it would have liked that sort of abuse too much.

Its not on that diagram Mart; its the long one which passes through the upper wishbones at extension of the sbframe...

mark said lower wishbone bolt, however the bottom arms arent wishbones though.

mart can you whack up diagram for the top part of the suspension and mark can tell us the number he means

:wink:

He did also say that it looks similar to the bottom front shock bolt....... so I think the one you have stated Mart is the one.

Easy to locate....

The part number Mark quoted is for the track control arm bolt. These are a standard UNF size and are available from motor factors or agricultural machinery suppliers.

The shoulder length (unthreaded bit) is important in this application - do not use a machine screw (threaded up to the head) even if it is the same overall length.

A metric size is not suitable because the diameter will be different, eg for 3/8"UNF applications M8 is too small and M10 too big.

Call these guys. I have used them to replace several bolts on my car including the exhaust manifold to head bolts. They are pretty cheap too compared to Rimmers. http://www.margnor.co.uk/=contact.htm

If they won't post or take cards, let me know, I'll pop in and get them for you and post them on.

metric

#15 Post by NO41SPRINT »

Hi ,know that in some cases that metric and imperial arent the same diameter size,but in some they very close.
chances of finding an imperial bolt in a long length is very rare,unc is better than unf though.
a fully threaded bolt is called a set screw.

I changed all my 5/16unf to m8 stainless steel on the steering joints.

anyway ,let me know
