How does the speedo actually work? The cable rotates from the tranny, that's clear enough. The cable has a square tip that fits into the bushing-thing on the back of the cluster, but then what? Is that bushing magnetically coupled to the needle? A spring? How does the cable translate consistent rotational motion to a relative position on the cluster?
I assumed that some bounciness was lack of lube between the round bushing in the cluster and the round housing in which it sat. Has anyone disassembled the speedo? Got pics?
I put a few drops of T-9 lube (bike shop; link: http://boeshield.com/) on the rear of the speedo cluster and that eliminated bouncing except at low speeds. I attributed that to initial static friction or some other low-speed phenomenom. |
Yak, youre the best!
Have been fiddling with the bouncing speedometer when driving. My use of the car is in spurts, and in the last week, it went 500 miles of interstate. I tried moving the cable and cluster any number of ways, ziptieing the cable in different orientations under the dash, etc.
I drove probably 300 miles holding the cable in different orientations. Some I could release and drive for a good while without any issue, very snooth... But the next time I drove after a stop, it would bounce.
I was at my wit's end, so pulled the cluster tonight and put about three drops of T-9 on the bushing. Seems super smooth and silent.
Before lubing that, the best orientations always had some cable noise. No noise now it seems...
Thanks!
