Re: v8 3 speed speedo cable to model a
.
The speedometer cable on a V8 Ford does NOT hook-up to the transmission. And the cable does NOT hook-up to a Model A trans, either. The cables on BOTH hook to a "turtle" which is mounted on the torque tube of each respective vehicle, as seen on this '35 Ford torque tube. DD The "turtle" is a very simple affair which bolts directly onto the torque tube. It's gear meshes with the 'drive' gear which rotates with the drive shaft. |

Re: v8 3 speed speedo cable to model a
I read this question as the mismatch between the turtle drive and the female receiver on a Model A speedo.

Me too the A has sort of a key swedged on the end of the cable and a V8 has a square swadged on the en of the cable I used a V8 turtle.

https://www.jalopyjournal.com/forum/...#post-11555128 Here is one thread. I'll find the guy I was thinking of. Correct cable for Oval speedo ('28-'30) to V8 turtle from Snyders. https://www.snydersantiqueauto.com/P...earchByKeyword Last edited by Tim Ayers; 12-19-2020 at 08:27 AM. |

Re: v8 3 speed speedo cable to model a
Are not the "turtles all the same?? Just the gear is different, depending on banjo ratio.

The 'turtles' shown in #3 above are the same, '32-'34 four or V8 and beyond with varying gear ratios as you've noted.

Re: v8 3 speed speedo cable to model a
The cable end that mates to the ‘28/early ‘30 speedo are different. The early A turtle has a matching female drive that can be swapped out to V8 style square drive
Until the OP confirms, the issue as I understand it is the cable end to Model A Speedo is not the same as a V8 and won’t work. |

Bratton's Has the shaft for the turtle in either the keyed or square cable end.
I would think if you are trying to run an oval Model A speedo you could use this part. https://www.brattons.com/catalogsearch/result/?q=23220 |

Don't know for sure but I'm guessing that Rusty at Speedometer Service in Colorado Springs could sort it out for you. Might be worth a phone call.

Re: v8 3 speed speedo cable to model a
.
You know, this is why I get a bit 'uppity' (SOMETIMES) about folks that either "CAN'T", or "WON'T", but definitely DON'T use either proper grammar, punctuation, terminology, or at least a reasonably complete description while attempting to get some of us "dummies" to KNOW what they're asking about. Turns-out that this guy (as seen over on the A-bone forum) is using a '39 trans ("78" case) with an open drive adapter bolted on to the back of the case. For those not familiar with what these open drive adapters look like, see the transmission on RIGHT side in the pic below. As you can see, the speedo cable hooks-up to these from the top, as there is no torque tube for a speedometer turtle to bolt to. Anyway, this guy's cable comes out and the loop is hitting the floor in his Model "A". Turns-out that he is looking for some form of a 90 degree adapter to get rid of the vertical loop in his speedo cable. Now, that wasn't so difficult.....WHEN explained somewhat reasonably to begin with!!! Rant over! DD ........ |
