Speedo fail
Written by pgrwhistler on 6/6/2010 at 02:51 pm

My speedo cable just went also @ 58,000 miles on a trip home from Ga.to Soth
Florida; seized up but didn't break the gear ?

> Hi again! Haven't been checking in for quite a while, but I wanted to relate a
quick story from a few weeks back. So I was riding out to Road Atlanta to watch
the AMA Pro races a little bit ago. Saturday rode out, spent the day, rode back
no issues. Sunday rolls around, and I'm headed out to the track when I notice
the speedometer and odometers aren't working anymore. Great, I thought, speedo
cable is shot. With many miles left to ride I started thinking about my recent
drop in gas mileage. I keep track of it on Fuelly.com, and since October it has
dropped from over 50 mpg nearly every fill up to under. Usually between 47-49
mpg. I started wondering if the cable was dragging, and bringing my mileage
down. Not actually affecting the consumption, but showing fewer miles traveled
per fill up. Thereby giving the impression of increased fuel consumption.
> Anyway, I got home that evening no trouble. Of course I had to cancel my turn
signals manually, like the common folk! Oh, the horror! LOL! I resisted the urge
to immediately get a speedo cable on order, instead waiting until I could tear
it down the next day. Upon inspection, the cable was indeed intact and
functioning when spun up with my drill. So took off the wheel and found a
broken tab on the drive gear inside the hub. From the fiche I ordered a new
gear, and the two thin washers. I think they act as bearings. Probably were
fine, but they were cheap and I was already in there. I decided to go ahead and
replace the cable. 63,000 on the original, I figured it had served it's purpose.
Also a small o-ring for the bottom connection of the cable. (I found out when
they arrived that the cable comes with a new o-ring.)

one.

resulted in 53 mpg!
> My conclusion is that my initial impression was correct. The old dry cable was
indeed dragging my mileage down, affecting my mpg. Also this was putting added
stress on the plastic drive gear trying to spin the cable, which resulted in
it's failure.
