Omega General Help / Re: Omega idler arm - where to get?

« on: 25 October 2011, 15:00:32 »

Well All German Parts accepted my order for one. For next day delivery. £55.60 inc the delivery charge. So let's see what happens.

Seemed to be plenty of parts out there, but are they the Chinese chocolate bush version or genuine? So a bit pricey maybe. But at least I can have some confidence it will work.

Got an advisory on the rear shocks. So might replace those as well. What is best at a good price? Model year '97 Omega 2.5 V6 CDX.

Omega General Help / Omega idler arm - where to get?

« on: 24 October 2011, 17:06:29 »

Some years ago I made the mistake of buying the chocolate bushed version of the Omega idler arm. The one on the nearside. As discussed in this thread.

Anyway it slowly deteriorated and is now an MOT fail.

Anyone know which ones one currently on EBay are good and which are crap?
Or where else to get in a hurry at reasonable cost.

Thanks,

For the record;

I still have an original bolt still in bag, I bought four new ones from Vauxhall at the time and only used three. I remember noticing the lack of corrosion on the originals. The unused one is dull grey.

The are M8x35. The hex head is deeper than standard at 7mm versus 5.25 or so. Standard 13mm across the flats.

The bag it came in is marked GM #24434133 and the cat number is 8 55 967, Made in Germany.

The head has makers mark KX2 and the grade is A.

Mine snapped off inside the threaded part of the cat and I also remember rooting aroung in the darkest depths of my toolbox for a harder drill-bit.

So some form of stainless steel methinks but not the standard A2. I guess 8.8 would be fine. But the heat and road spray will corrode them. And next time you need to separate the exhaust = £$%><@*.

As I recall the centre boxes to cat bolts are (fine metric?) stainless steel, two per side and not available in the likes of B&Q. I would replace with new stainless or else they will all shear off next you want to separate them .

If any of the the bolts shear off you will need hardened drill bits to drill out. (The bolts screw into theaded holes on the cat side.)

I damaged the threads on one of mine, so I  I used a longer stainless steel bolt with a stainless locknut and washer and it's been fine.

Stainless bolts can be had from a Vaux dealer, engineering supplier or marine chandlers. Or the internet.

Omega General Help / Re: steering idler nonsense!!

 :-[I replaced the idler on my '96 2.5CDX about two years ago. It was never entirely satisfactory and now it's worse than ever. OK. I am an idiot, it seems very likely I bought the crap version.

So I am going to buy the good version but I just can't face trying to separate it again, it took me all day last time. So does anybody know where to get a splitter that works for a reasonable cost. Neither of the ones I have would fit.

Thanks.
