Replacement Gears for speedometer

[menesesjesse]

I was taking apart a KM speedometer to clean and lubricate before it will return to service.  I noticed however the plastic gear that moves the odometer is shot.  Does someone know a source to get this gear.  I have attached a picture for reference.  Thanks.

Porsche 911 owners (as well as MB and other enthusiasts) use the below-linked source for replacement gears. While I don't see 113s listed it may be productive to email the owner to see if he knows of a source or will take on production of this component. http://www.odometergears.com/


Then there's always North Hollywood Speedo who will fix for you: http://nhspeedometer.com/mb/1.htm

I contacted http://www.odometergears.com/ earlier today and they dont have the gear however he said he may have a source.  I will pass this on if it pans out.  I am wanting to repair this myself since I already know what the issues are.  Any other source of gears would be good before I resort to someone repairing the gear.  Thanks

Hello Jessie,

Most likely some of the instrument repair shops have one (Palo Alto Speedometer etc.). Otherwise, it looks the same as a Mercedes sedan gear and lots of those are available from sedans of the era. I can check this possibility for you.

Thanks for sending the parts for the speedometer.  I did find out the sedans gears are not compatible due to the length of the gear.  I guess they could be engineered to work but that would require cutting.  Palo Alto installed the gear on the original shaft and it looks like a winner.  I thought I would share this so people would know I had tried the gears and may save them some time.  Palo Alto did a great job but did say they generally dont do 1 gear jobs for the most part.  I guess I got lucky.  Thanks for the help
