Speedometer problem - 1961 Ford F100 Unibody

Okay boys and girls.. I need help here.. I'm stumped.. I have a 1961 Ford F100.. I bought a new speedometer cable (speedo wasn't working).. put it in and NOTHING.. so I took it out, checked it by spinning it with a drill from the transmissions side and my speedo works.. When I stuck my finger in the hole where the cable inserts into the trans.. Seems like it's not connecting to the worm gear.. I checked again on the right cable and was confirmed that I "supposedly" have the right cable.. But I need a little bit wider worm gear on the cable side that inserts to the trans.. Is there another year that is a bit bigger diameter so it will connect with the gear in the trans? Am I missing something here??? Thank you all.. I get more good info here and am waiting expectantly from you pros.. Thanks!

William is gaining momentum as a positive member of FTE.
The plastic drive gear on the cable should fit well into the hole on the transmission. I'd look in the transmission to verify that you have a worm gear on the transmission shaft. New plastic drive gears are available in junk yards and off ebay. Sometimes the plastic drive gear will not seat in the mount in the transmission. Sometimes the little extenshion on the previous gear is still in there. Get a mirror and flashlight and check it out.

Depending on what transmission the OP has in his truck, the DRIVEN gear (end of cable) could be nylon, iron, or steel with a fiber end.

The nylon gears are available from Ford, same ones used for over 30 years, beginning in 1960.

Speedometer DRIVE gear (on output shaft) could be steel or nylon.

Here's a pic of the 3 M/T speedometer cable and attaching parts. Cable: 17260 - DRIVEN gear: 17322 - Clip to retain gear to cable: 17292 - Rubber O-Ring (oil seal): 17298

The speedo cable I bought is steel on the end with a groove to fit against the drive gear in the transmission.. Thanks.. But what Number is saying is there is no "bigger" sized end to go into trans? they are all the same size? Thanks

The speedometer cable is composed of an outer housing, inside is a woven steel core that can be replaced by itself.

There are THREE different types of speedometer DRIVEN (end of cable) gears. Could be nylon, iron or a fibre gear riveted to a steel shaft.

1961 F100: With 3 M/T or 3 M/T with O/D or with A/T? If A/T, is the engine a 223 or 292?

If the DRIVEN gear is iron or fiber, there will be a Ford ID number stamped on the shaft, like 01T-17271-A

There are TWO types of speedometer DRIVE (on output shaft) gears, nylon & steel. Same applications apply as DRIVEN gears.

thanks Numbers.. I have the 292 V8... and the end of my speedometer cable is steel.. but my question remains, this is not fitting up to the gear inside the transmission housing.. I'm wondering if this is not the original trans? I think it is because I had some work done on it and they said something about getting the "original" parts for it but still could be a different trans. Can I USE a different cable for maybe a different year that is slightly bigger in diameter? Would you know the years I could use? I know I'm asking a lot.. thanks so much for your reply..

Where did you get the present speedo cable?

The DRIVEN speedometer gear at the end of the cable: Is it nylon, iron or fiber riveted to a steel shaft?

I need to figure out the original application for the cable and gear, so...

1961 F100 292: What type of trans does it have, what is the rear axle ratio and the tire size?

AXLE code stamped on the 2nd line-far right of the Warranty Plate, riveted on the inside of the glove box door.

Post the axle code.

NUMBERS.. have a couple of questions.. On the sheet you posted and referred to the number - C1TF-17260-C looks like it's a 5 instead of a 6 on the sheet (I could be wrong)

Also on the part number you gave me - CODZ-17271-A - when I googled it Steeda part says its for Manual transmissions - I have an automatic, will that make a difference? Also do I slip it over the existing speedo cable I have and then retain it with the ring part that you gave me?

87036-S94 - says it's for Mustangs will this fit my Ford F100? sorry for all the questions, I just don't want to screw this up... Thanks!!!!
