I've searched the web high n low and can't find a real answer. I've talked to 2 'experts' and they both gave me opposite answers. Hopefully someone here has actually done this to know 100% if its doable. I've got a truck with a 14613 cable drive speedo and I'm wanting to swap it for a 16913 to get the double OD. Can a 16913 be easily converted to run a cable drive speedo?? No, I'm not going electric, and no, I'm not wanting to run a GPS or app for speed. Basically looking to run a newer tranny with and older speedo setup. How doable is this??

Well. Assuming it works like cars.
You'll have to find a way to install a shaft with splines and a gear to run the cable. And a housing that will fit it all.
Could be doable. Maybe.Keepforgettingmypassword Thanks this. -
I would think just swapping the rear brg housing from old to new, with new gasket, seal, and yoke nut.
Some pics of the cable drive bearing housing would help -
One option is take a RTO14609B and a rear box off an RT14613. The RT has an under drive auxiliary box instead of an overdrive so you will end up with the same ratios as a RTLO16913. You will have to use the main shaft out of one of the 13 speeds so the rear box will fit to the 14609b. It will keep a good low gear and still step out in high without the whine of the aux turning.
I agree this is not as good as a 16913 honestly it’s just not. But it is an option if the 16913 can’t be changed to cable drive. I know the 9 series has a different housing and seal on the tail from the 7 series. The 7 series is as good as the 9 series splits are preselected like the 9. It’s possible that the 7 may be converted easier. My 85 with the 14613 has electric speedo so I know those were both way. But never having converted one back to cable I don’t want to stick my foot in my mouth here. But I would think it’s doableSL3406, Sons Hero, blairandgretchen and 1 other person Thank this.
