Speedo whirring noise
« on: November 08, 2018, 01:26:32 PM »
This has just started, a whirring sound from the speedo not the tacho only noticeable when going slow when the engine is quieter. Took out cable and greased the speedo end and it is slightly better now but still there. Speedo still functions normally with no jumping

Try pulling the inner all the way out and see if is kinked or damaged, had that before

Take the speedo off,  spin the drive square and see if you can hear the noise. The drive can be spun with a match stick, if the noise is evident try a few drops of light oil around drive spindle and turn the spindle. The oil will work down the the housing.
