Hi everyone, I got a T-86 3spd overdrive trans off ebay a few months back w/o the slip yoke. My 1962 f100 shortbed (223 six cyl. engine) has a higher spline count than the 16 spline output shaft of the newly acquired transmission. How can I find the correct 16 spline slip yoke for this transmission. I think the u joint will probably be the same size as the orig. driveshaft. Thanks to anyone that can help solve my dilemna, it's the last thing I need to actually make the unibody road-ready in time for Hot August Nights out here in Reno.

 

Off ebay? Uh oh....Have any idea what that T-86 is from? Year and model. Cars use the same transmission, but the yoke is different. The Ford ID tag (prolly missing) is bolted to the case.


Here's what the 1957/63 Ford truck parts catalog states:

1962 F100 114" wheelbase; 3 speed O/D; B7C-4841-A .. Slip Yoke .. 28 splines ~ 1310 Spicer u-joints.


Your o/d unit has a 16 splined output shaft? Now you know why I need to know what the T-86 is from...You see, this same Warner Gear T-86 3 speed transmission and overdrive unit was also used by: Studebaker, Nash, Hudson, Kaiser, Frazer, and ******. Without an ID, who knows what it's from. You will also need: the relay, cable, kickdown switch, wiring harness, solenoid and governor. Without these parts, the o/d won't work whether it's right or not.

 

I found a slip yoke that is 16 splines. It was used on the earlier O/D equipped trucks from 1948/56.

Here are the dimensions: 1310 u-joint / 16 splines / length: 5 3/8" / Overall spline diameter: 1 21/32" / inside diameter: 1 3/16" / Ford part number: 01Y-4841

 

Thanks for respnding to my thread. The auction listed this t86 came out of a '53 F100. I think you may have the correct slip yoke. I'm going to the shop and take some measurements of the orig. slipyoke and the tranny output shaft in/out spline diameters. How do I know if my old shaft has 1310 u-joints? regards, Michael

 

1962 F100 2WD short wheelbase 223 U-joints are Spicer 1260's. What you will need is a two way u-joint 1260/1310. Two 1260 u-joint cups for the shaft, two 1310's for the yoke.

 

I took some digital vernier caliper measurements: overall length is 5 7/8" (orig yoke), The ebay t86 has the R10 F-1 OD- output shaft protrudes about 3/4" past seal lip with an overall spline diameter of 1 3/16", inside spline diameter of almost exactly 1". The inner diameter of the seal is 1 1/2" which matches the orig. yoke outside shaft diameter. The orig yoke's u-joint width is approx. 3 1/2" with a bearing cup diameter of about 1". Casting #'s on trans. are TAAA- 7222-A (there's also a 6 underneath them). I have the original governor, relay and wiring intact, cable and solenoid, plus the solenoid and governor that came with the ebay t86 which may be 6 volt so I'll just use the original system. Do you think my stock speedo cable will work? It seemed to slip in up to the gear teeth but I didn't want to force the issue until I know they interchange. By the way I already installed the tranny and by the looks of it, it's the right length for the stock driveshaft. If I could just find the correct yoke... Thanks for your time and help with getting another slick back on the good foot.

 

One more thing. The ebay tranny has a boss and holes for a cross member on the bottom of the R10 F-1 overdrive unit. I wonder what it came out of originally.

 

TAAA-7222-A = that number is on the removable side plate where the shift levers are. Warner 3 speed O/D is from a 1953/54 F100 6 or V8. 6 volt system.

1962 F100 speedo cable: 3 speed: 69.82" -long

1962 F100 speedo cable w/overdrive: 76.24" -long

 

Well I guess the ebay seller had it listed correctly but I wish he'd sent the yoke. Do you have an idea of the part number I need and if it's still available? Thanks for looking into this, Mike.

 

B5C-4841-A is the part number. 5 11/32 O.A. 16 splines. Lemme check a few sources for where one might be found, will post later.

 

Thanks for your help. I found the yoke at my friends drive line shop. He blasted it, smoothed the shaft and gave it to me for nada! Lesson... always take care of your friends when you have the opportunity you never know when you'll need their help and it just feels good to help when you have the proper resources. Now if I could just find a starter and glass bowl-type fuel filter, I think she'll turn over and eventually run!

 

Would this the same one for a 57 3-spd with a 110 in wheelbase?

 

B6C-4841-A .. Slip Yoke - 1957/60 F100 110" wheelbase with Warner T-86 3 speed (no overdrive).

B6C-4841-B .. Slip Yoke - 1957/60 F100 110" wheelbase with Warner T-89 Medium Duty 3 speed.

B7C-4841-A .. Slip Yoke - 1957/60 F100 110" wheelbase with Warner T-86 3 speed with Overdrive.

Here are the specs (#'s 3 - 4 - 5) for these three slip yokes. Let me know which one, I'll see if anyone has it NOS

 

I'm really not sure which transmission I have other than it's 16 spline and it doesn't have OD or the extension housing. so that rules out #5. The only thing it has on the door plate is '3 spd' and '3.70'. The first part of the VIN is 'F10K7R'. I have casing numbers if those would help.

 

The Warner T-89 was an option, so I doubt your truck has it, but I posted the specs so you can verify.

There's no code within the VIN that decodes to what trans the truck has. All what you posted decodes to this:

F10 = F100 / K = 272 2V / 7 = 1957 / R = San Jose CA Assembly Plant.
