Truly a MPSIMS, Here’s my story on how Saturn attempted to rip me off for a .10 cent gear. (That I figured would cost me 10 bucks)
Last Saturday, I look at a 93 Saturn wagon. The Odometer has 67K on it, but it was “discovered” broken on the test drive.
So I buy it, prior to researching the cost of repair. (Bad move) I had noted in research of Saturn’s that a red gear in the odometer tended to break, so I figured no biggie, what’s a gear gonna cost. I go to purchase said gear, ot oo, it’s only availible with the rest of the dash attached, for about $400.00. I said nevermind, and asked who I should call about this problem. I called, the rep took my information, they called back and said, they wouldn’t help as the car was to old. We discussed it, the only thing they would offer was “you could purchase it in a junk yard” This gear is made of a plastic that doesn’t seem to like a car environment much. It’s soft, no very nylon like, so a junk yard part is likely going to fail quickly.
I’m kind of a pack rat, and have 10 or so car sterios, from the “old” days. So I start tearing into the autoreverse cassette decks, and find a gear that’s just a bit to big in diameter. (around .050) I try it, it’s to much for the stepper moter to win. So I proceed to sand it down, and notch the teeth deeper, until I get it working. It Works Great now, the gear is nylon, rather than thermoplastic, and should outlast the engine.
So there you go, If you have an older Saturn, and the odometer breaks, take a good look at that cassette deck. <smile>
Just FYI, It was a Kraco autoreverse unit, the spindle gears were the one’s I used. Had to cut down the shaft of the gear, but the pin diameter is perfect. A small nylon washer was inserted on the shaft to provide clearance. I made an extension cable for the odometer so it would work outside of the dash. It was rather fun to have my odometer sitting on the passanger seat.
