My speedo is out because my speedo gear has too many teeth, but I've been told that the speedo gears are not interchangeable.

 

Is this true and if so, how do I make my speedo correct?

 

Thanks,

Untrue.

 

There have been a few threads about gearing lately. There is a plastic outer gear that fits into the gearbox on a spindle shaft and can be easily removed from where the speedo cable attaches to the gearbox. Typically 19, 20, 21 or 22 teeth at least on a T series. Then there is an inner steel gear (typically 5 or 6 teeth) that is located within the extension housing of the gearbox so more complicated to change.

 

My mixing and matching gears, you can achieve the desired ratio.

 

Have a search for the thread that describes how to calculate what you need.

 

Gears are about $50 new but you can easily pull them out of boxes at wreckers. K series plastic gears are larger in diameter than T series plastic gears so not interchangeable. Commonly an auto box will have a different ratio than a manual.

Oooh ok that makes sense, thanks :)
