Postby GaborTiberiu » 18 Jan 2013, 18:44

va salut , sunt nou pe forum .. asa cum spune si titlu... am o problema cu un saab 900S. e din 97 , motor de 2.3 benzina.. ieri cand m-am oprit intr`o parcare am parcat cu spatele , si am oprit motoru nici o problema pana atunci. am lasat masina in "marsarier" adica cuplata in aceea treapta. cand sa o pornesc.. surpriza ca nu mai pot sa o scot nici din viteza nici sa invart contactu! ca si cum ar fi blocate amandoua. putin ajutor ?

Salut,

Contactul e de vina.

Uite aici o rezolvare:

Im back with the problem solved, here is the deal.

Remeber the symptoms were that one morning the key got a little stuck when trying to start the car, then that evening it would not turn at all. There was no gooey/slugish feel to the mechanism, only a sudden locked feeling.

Ok so I removed then entire ignition assembly from the console, this is not hard to do at all, it only requires puilling apart the dash and console and unbolting the gear selector. I'd say it takes about half an hour or so to get the mechanism out.

The actual pin/tumbler assembly is encased in a aluminum housing and can only be removed but turning the key to a specific spot and then depressing a little spring loaded button on the side of the case. If the key turns this is easy. My key was not wanting to turn at all.....until suddenly after lots of random banging and turning of the key...it turns!! Find the right spot, depress the little button thing and the tumbler pulls right out.

The tumbler itself is then inside another housing which has to be taken apart to fix this problem. There is a white plastic cap with a spring below it of course, remove this cap and spring to get to the end tumbler shaft. There is a spring loaded pin in the end of the shaft, depress the pin and turn the shaft until you can access the pin and pull it out (remember, spring loaded). At this point the internals should come out. Keep the key in while doing this, otherwise you the little pins and their tiny springs could fall out.

Now that its out I see the problem, worn pins! The pins are just not depressing enough anymore and are essentially keeping the tumbler in the locked mode. They should be flush with the tumbler barrel when the key is in, they all were sticking up at least a little. My solution was to grind the down the tops of these pins so that the tumbler can freely turn again when the key is in. This of course will not last forever as the pins will continue to wear, and they won't expand as much as they used to (reducing security, but not by much). The pins are coded and could theoretically be replaced if you could get new ones (doubtful).

Everything works great now, lets hope the wearing goes at same pace as before, if so I should get anothet 150,000 before the pins stick up again. I hope this helps someone in the future, I surely will not be the only one that this happens too. Also I have read that a factory matched replacement can be 270$ , ouch I'm not going that route.

Later,
Mike
