6 to 10 spline coupler question.

These coupler are used in early Ford torque tubes, to run a 6 spline pinion into a 10 spline torque tube driveshaft.

Is the size of the 6 spline end the same as the 6 spline on the output of an early Ford gearbox?

I was thinking about my long term project of an Iacanno/Ganahl "pickle" inspired Lakester to run at Lake Gairdner, in South Australia. Initially I'll run a stock early Ford rear, then as the $ enable me, a Q/C. I have a gearbox , rear end, torque tube and brakes, and was looking at the easiest way to couple them in the shortest distance, much like the original, which runs a La Salle/Halibrand combination. The engine will be a 261 Stovebolt six, instead of an injected 12 port Jimmy.

Thanks in advance.

 

I'm almost certain they are the same. What you're talking about should work - until you grenade the trans or rear.

The 6x10 coupler was to be able to run a 10 spline rear with a 6 spline driveshaft. If you want to run a 37 or later rear which is 6 spline,the stock coupler would be the one to use. I have a trans output shaft and a stock 6x6 coupler and will see if it fits.

 

I tried a '48 Ford ****** in the dragster. The U-joint female spline plugged right on to the male pinion spline. It used an adaptor like the one pictured.

 

That's exactly what I had hoped might happen, and its the type of adaptor I was looking at making.

So JF when you say "tried" I imagine that it didn't last.

Thanx for the info guys - viva La HAMB!!

Cheers

 

Stove....It didn't last because the bellhousing alignment was WAY off and bending the ****** input shaft. That also tore the centers out of the clutch discs and made the car difficult to push with the clutch disengaged but the ****** in gear. If everything had been straight, it might have worked better. Plus, the ****** was a junkyard item.

We were just kids !

The 45 degree wheelstand at 100+ mph was exciting.....

 

I went and checked the splines. The splines on the back of the trans are bigger than the driveshaft splines. I would suggest cutting the ends off the driveshaft and welding them together. You would use the u-joint and the bearing in the end of the torque tube.

 

What kind of ****** ?

 

The trans is a 39. The front u-joint splines on the trans output shaft are bigger than the ones for the driveshaft. I like the short torque tube you showed. All I was saying is that he will have to use the u-joint to get the same splines as used in the driveshaft. He will have to shorten his driveshaft to fit and make a short torque tube as you showed.

 

By the looks of things you are both correct, Andy, and JohnnyF.

I'll have to make a similar looking torque tube to the one you showed JF, and use a real short t-tube, as you suggested Andy.

Thanks heaps for setting me one the right track,

Cheers
