worn speedo input

[goggstrotter]

following the replacement of my duff speedo i decided to investigate the cause of the last ones failure.

when i finally got the input shaft out i noticed loads of crude and bits of worn bushing, which finally seized the drive.

from now on i will squirt a little bit of lubricunt down my shaft every 10-20 thousand KM.

any comments ?

.....surprised the site spell-checker didn't pick this one up.....

I can't even type Scunthorpe without it intervening!

Seriously though, it is fatal to speedometers to have oil ingress. If you are going to lubricate the cable, do it from the bottom only, and then only sparingly.


Edit: The bloody site spell-check thing ain't working!!!

i understand from my british bike days that grease getting into the speedo is not good, but after dismantling the speedo i cannot see that a slight bit of lubricution will do any harm....but i may be wrong....famous last words.

how reliable are BMW speedos....mine is made in the UK which doesn´t say much.....plus the BMW service book has entries for servicing up to 140,000 km and 4 entries for speedo replacement....does that mean they are only good for around 35,000 km....if that is the case i´ve done well getting 90,000 km out of mine.

does riding on average 6 hours a day overheat the input shaft......ooerrrr missus !!......pick that one up double entendre checker
