Replacing antenna - 90000

I do not know about the _90000_ but in a 900 (both classic and NG) it's just removing the plastic screws with a standard screwdriver (1/4 turn) and pulling the lining from under the rubber boot seal. I suppose in a 9000 it is the same. :-)

Thx, that's useful. No it's not a 90000 :-) it appears that Saab 90000 was the nickname for a 9000 based Saab ambulance since 90000 is the emergency number in Sweden.

On my CS Aero, you pull off the rubber trunk seal which also holds the lining in. From what I remember it is fairly obvious once you are in there. When I was replacong the broken aerial, the old stub wouldn't come out and I had to dismantle the whole thing, so I could push it out from below.

Are you sure you need to replace the whole aerial assembly? If the mast has been snapped then all you need buy is a new mast, a lot cheaper. Undo the nut on the outside, remove the remains of the old mast (will have a long white nylon 'tail' attached to it) then feed in the new mast and tail then do up nut.

OK it's worth a try. The mast was bent by reversing under some kind of air conditioning structure in parking basement, one of those big square pipework. Always reminds me of films where the actor escapes through such pipes. The mast no longer moves, but the motor sounds ok.

If you check e-bay you will see replacement mast listed. I need to replace mine but am going to wait till gets warmer.

Thx. Undid the outside nut, but the mast is still attached to the main body of the aerial. How do I remove the mast without taking out the mechanism from inside? I have got the replacement aerial with the nylon tail, it also came with a small tube of the diameter as the mast and about 1.5" in length, and another larger tube which looks like a turning tool.

I think you just need to pull to overcome the resistance of the motor (the toothed nylon belt is wrapped around the drive wheel in the motorised bit).

These instructions are pretty good...

Whilst in this example the aerial unit is out the car, it is just the same with the unit fitted,

With the nut removed, turn the radio on and the motor should then push up the aerial and spew out the nylon tail too. At this point it may help to "assist" the motor by pulling.

Meanwhile, you have taken notice of which side of the hole the nylon teeth are.

Once out, get your new aerial and feed the nylon tail into the hole, with the nylon teeth oriented the way the old one came out. NOW get an assistant to trun the radio off. Giving the nylon tail a slight push the motor should catch the teeth and draw it in. Again you may need to assist the motor in getting the mast itself in. (Do this with the mast fully collapsed)

Replace nut - Job done.

I've used this technique several times after my brother in law showed me how it's done. He fits stereos, DVDs alarms radar detectors, phone kits etc to some very exotic vehicles for a living so he knows his stuff.

I have got the replacement aerial with the nylon tail, it also came

You ignore the fact that the broken bit of the mast is usually corroded into the base of the mechanism. I haven't had one yet that just winds out and winds in the new one; I have had to dismantle the whole mechanism.

No I don't. I've done three of these so far. One on my 9000, one on a NG900 and one on my C900. In none of these cases was anything corroded to anything. Therefore since in my experience this doesn't happen, I have ignored nothing. Usually (100% of the time in my experience) removal/replacement using an industry recognized procedure works.

As for dismantling old mechanisms, you are kidding right? Either you couldn't get hold of a cheap OEM replacement in NZ, or you have way too much spare time!

Al

You might not believe it, but @tis so, they were both broken off flush with the wing. I used OEM replacements and they both work OK now.

I replaced the mast in our '95 900SE just this weekend; had to take everything apart to get the broken piece of nylon/plastic out. After that it was easy to put a new mast in.

Hmm, it seems my mast changing experiences have all been pretty blessed!!

Al

Yes, took it to an independent workshop today, the piece of nylon was broken, so they had to take out the mechanism from inside the boot.

The problem really started by damaging the mast when colliding with air vent pipes in an underground parking. When rectifying the mast it probably got significant resistance, which mast have worn out the plastic band. The workshop also fitted the new gearknob, also not so easy for the inexperienced.
