Well last night my speedo quit working again. I pulled the thing out of the side and it is the gear that the speedo cable slides into.
It failed right where the shaft connected to the gear.
This is the second gear that has bought it in about a month and half and it also failed in the exact same place.
Last fall the clip came out of the gear on the output shaft. I dont thing there is any wrong way to put that back on. Neither gear has shown abnormal wear to the teeth. The last gear looked as if it sheared of at the point and this one you could actually see how it twisted off.
Both times I was going down the highway. Its a stock N/A 6.2 so Im highly doubting its to much horsepower/torque doing this. Although thats what I told my Ford loving buddy.
Has anyone else experienced this problem, and does anyone make a hardened poly gear?
