These mysterious mechanisms GM
Cadillac CTS not American “Logbook” These enigmatic arrangements of GM
Often come across entries in the journals of our STS the defect as a missing lumbar support. I found out about this trouble by accident, when and why it sat on the passenger seat. Apparently it has not worked for a long time, with the past owner of the car, and my passengers to my questions — do you feel what a good lumbar support -answered — Yes Yes of course, but as it seemed to me, as that is too confident. now I understand why. Many people in life are luckier than me — they have a machine under warranty, and they do not suspect that hidden in the depths of the seatback, and that changes in such sad cases .
To start I had to dismantle, or rather inexperience with half-broken rear plastic seat cover, latches which I then glued into place. Next, I saw a funny dangling construction dangling wires, perekladnyh and springs. Is this optimalnaya the design of this site. I came up with different simple design of the motor and pin it resting in the back. The main reason was hidden in the round box is the reducer, which took the rope, a motor hummed properly without giving any effort. Apparently the inventors didn’t want the secret of the boxes was opened and closed her tiny little screws with a tricky slitzer. Steady hand he was converted on my own, more convenient to open. No wonder there were such intricate cogs, the engineers as a hint that that this box is only opened on the 20 th level. In General, at the opening in front of me for a moment appeared very mysterious ” Antikythira mechanism “, after which he collapsed on components. My crying …
But in the end, by fits all the gears of the mechanism were tucked into place, inserted into each other in a 2 tiered structure and turned right angles. The complexity and the reason for refusal was the only one Komarom piece toothed wheel, fixed to the end of a rope. The wheel is experiencing extremely heavy load pulling on the cable, which in turn bends the metal(!) plate, and which pushes us in the back. Moreover, the wheel can break under excessive long press on the button both in one and in other side, there is no electrical switch — limiter, it rotates the projection abuts the locking mechanism and cracking while we stupidly again and again we press the button. The wheel was glued with super good glue, a metal plate upirayas in the back was a little arched, in this state, the force on the compression need much less under her back was laid a layer of paralon. Me through all the fittings – Arzani on the seat is more convex in the lumbar position of the back-up seemed more convenient. All cantilevered structure made of struts and laths has been oiled and tested on shaking the excess noise and finally hidden behind the plastic. In the driver’s seat the same method strengthened with foam rubber lumbar support .
Dealers I think in this case changing a lot of parts together because they’re all related — motor, this box is the reducer, guide rope to the other there is simply nothing more to break. So, who is a lame duck like me who don’t have warranty try to save .
I usually post some photos their fights, unfortunately this time I was so concerned about the problem that after the first photos it was not to perpetuate the history of plastic gears …
