transmission speedometer gear
Hello all, Wondering where to find the plastic speedometer gear that links transmission to speedometer cable on my 1958 3 speed for the 223. I think 259 series. Mine's broke and I'm having trouble locating another.
Also one of the thrust washers rubbed some grooves into the case. Should case be replaced?
When I first test drove truck I heard loud clinking sound, I'm wondering if thats from the missing tooth on my 1st/reverse slider.

I ended up smoothing the surface as best I could (not much) and slathering Loctite Sleeve Retainer on the grooved surface, then slapping a shim and new thrust washer on it. It's working fine so far. The shim was necessary to get spec'd end-play. The absolutely critical thing is to make sure the tab on the thrust washer engages the slot so it will not rotate -- that's what makes the grooves.
Yes, a missing or badly chipped tooth will make a thunking noise, until it makes a really big thunk and locks up!
