I need a VERY hard to find part - CarForum.net - Car Forums, Automotive News and Community

*Kenny McCormick* · 03-26-2010, 07:37 PM

Namely, the speedo driven gear. It's plastic, goes on the end of the cable, and turns it. Mine has about three teeth left, and those are quite worn.

Now, cables are EASY to find. I can get those at every parts store locally, RockAuto, you name it. But I don't need a cable, I need the gear it attaches to, and that I can NOT find.

That's where you guys come in...help me find this stupid gear. It's for the F150 in my sig, all details you should need regarding the gear should be there. Rear end ratio is a 2.49, but if you find one for a 3.27 link that as well as I will be replacing the 2.49 ring and pinion soon. If you need more details, ask and I shall provide as best I can.

Good luck!

Are you talking about the gear that sits inside the transmission?

Or is the locking clip the goes in the back of the Dash?

Do a search for Speedometer shops or Repair. They might have the part you are looking for.

The gear that goes into the transmission. The end at the speedo itself is fine, and when the gear does spin the speedo reflects this. The plastic gear is just so badly stripped that it's hopelessly off.

Most trannie shops have a small colection of misc. parts like that.

how complex is the gear? any machine shop would be able to make you a new one if necessary.

not very but the sizing is critical you would need exact demensions to get the right speed reading. They come in various sizes and can be bought form trans shops or trans supplie stores.

Yup... Trans Shop or.. A junkyard

Not to mention the amount of money I'd spend having a gear machined to fit would be astronomically high. It'd be cheaper to replace the transmission with a M5OD from a 1992-1996 F150. Also, I have NO idea the tooth count or pitch information, and there's no real way to get that information from my old gear as it's that badly ruined.

Thank god Ford made it out of plastic, as if they had made it from metal and it screwed up it would have ruined the output shaft as well.

I'll start calling some trans shops, but the junkyard is fresh out of 80-86 F150s at the moment so they won't have the gear right now.

If I had the information, I could get you one cut from abs plastic for free. I could calculate all the variables if I knew how many teeth it had and what the diameter of the gear was out to a hundredth of an inch.
