A mate dropped off his K’s speedo head today to see what usual Odometer carnage may have occurred, as it hasn’t worked since the old girl was purchased earlier this year. 

Well....no real surprise, the gears were in a fairly sorry state, however weren’t stripped totally. The gear set was locked up due to the driving gear shearing off and locking the set. The gears were also solidified together with what I’m assuming was grease that had turned to wax. 

It appears that someone had been in there before - anyone else ever seen yellow gears? This K’s a jap import.

There were also two pins that had become detached from the board which required resoldering.

Ah, that’s better!

Fingers crossed another $4.95 fix works Wink

I think BMW probably used whatever colour the manufacturer sent. I've kept two sets from speedos that have failed beyond repair. IIRC (because I can't be bothered to go outside and find them Very Happy ) one set is green, white and orange (hurrah! for the Irish) and the other set is yellow, white and orange.

Hi
Seen this before and I also think the colours "don't matter" or are not of significant value...
Regards and good luck

I have been having a hunt around and cant find anything (not unusual for me) but I do recall that there is something to do with colours and whether it's for MPH or KPH.

if you look closely on the gears there is a tooth count stamped into them 

i pulled apart and documented the tooth count that i found in gertys gear set years ago 

and actually posted the tooth counts , but time gets away and of corse cant find the edited picture with the labels ....doh !

heres an example of the lettering i was talking about 

Another dud Odometer 2014-011

by the way as the plastic deteriorates it can colour the the next connecting gear 

but i did find this 

Speedo gear sets
 
 
 
Part number 236 is white with 11/33 teeth (The pink colour has blended onto this cog from the other one)
Part number 237 is pink with 23 teeth
Part number 238 is brown/orange with 34/40 teeth (this is the one that's totally stuffed)
Part number 239 is red/orange with 16/44 teeth
The primary gear is brown with 12 teeth







but did find the labelled pic  after all

Hi all, thanks for the replies, 

The odd yellow gear is the same tooth count as the orange 34/40, as has been suggested must just be a manufacturer “flavour of the month“ thing perhaps. I appear to be now collecting a selection of mashed-up gears, maybe I can melt them down into something.... Surprised

I have received word that all is working, even the micro-surgery soldering on the fragile pins cheers

BTW I found by removing the pin, soldering in a piece of copper wire to firmly locate it back in the board & then carefully heating the pin seemed to ensure a reasonably good hold (apologies if this is obvious stuff to the sparky types, I confess to be quite inept in such matters)

Regards

Dan
