Yellow Speedometer Gear

[KenFirch]

Okay, who's hoarding all the yellow 240Z 16 tooth speedometer pinion gears?  

No problem getting the 17 through 20's, but not the original yellow one.  🤔

Found one from another guy in town, but it's teeth didn't look so good.  Using it anyway.

Haha.. hoarding.. 😂

Some z-people called me a hoarder...  @bartsscooterservice   I did not know that the yellow one was the original for the 240z!  Thanks!

I got one brand new so i cherish that one!

Are these NLA from Nissan?  I'd check with the local dealership.

I looked in my sellar and found the part in a bag with the part number and packing sticker with date!  found a old price of 68 euro?

Btw.. it's a bit greenish yellow and .. i counted the 16 teeth.

partnr: 32703-22000  bought in 1999!

I have three - used - so I guess you can count me as hoarder... (no blacks, one white, no reds, but three yellows...)

Can we 3D print them? Or would the oil eat the ABS plastic?

Backstory…Had a few oil drips from the speedo cable area, not a lot, just annoying. Ordered a new o-ring and seal, disassembled and installed. No more leaks for a few hundred miles, great! A few weeks ago I was getting on the freeway, rather briskly I admit, you know, get up to 80ish or so to merge with all the other crazy drivers. I notice the speedometer jumping around a bit, and finally stopped working altogether. Weird, pull the speedo gear out and teeth are really worn on just one side of the gear. Speedo cable spins fine from below, no kinks in cable, pinion gear turns fine in the carrier. Can’t figure out why it failed. Maybe tail shaft bearing is worn, allowing the worm gear to flex down onto pinion? Anyway, so began my search for a replacement 16 tooth yellow speedo gear. Found one, but it’s not in the greatest shape.
