Rembrant Posted July 30, 2020 Share Posted July 30, 2020 Ron asked what I meant by "Blue & Gold" Well, there you go. 😲 😈 Hey Jim, While you're on the topic of Bricknose transfer cases, I have a question...or questions... So the Bullnose 1/2 ton trucks used the NP208 T-case? And then in 1987 switched to the BW1356? On the 1987-1991 trucks, the speedo cable went into the transfer case, correct? What T-case was used from 1992-1996? Can a speedo cable be connected to them or do you specifically need an earlier T-case? At some point they switched from having a slip yoke in the T-case to a fixed you with a splined driveshaft? Link to comment Share on other sites More sharing options...

Cory, To the best of my knowledge it is only the tailshaft and housing that has provision for a speedometer cable. My '87 has a VSS tone ring and sensor but it's only used for the RABS. Whether the later 1356 has a spot for the gear locating ball is beyond me. But, if it does, then all you would need is a housing with the boss for a cable. From what I see in Gary's charts the 1345 was popular too. The fixed yoke and flanged models were used in Broncos and 150's. AFAIK all the 250-350 applications had the slip yoke like I do. 350's got a 1356 with an aluminum front case half that has a PTO. The Zf-5 and T-19 have PTO's both sides. So there's three options on 350 trucks. Link to comment Share on other sites More sharing options...

PSOM's came later (with the Aeronose trucks, I believe) Link to comment Share on other sites More sharing options...

Cory, my 92 Bronco has an electric speedometer, and I think it uses the rear diff sensor that Jim mentioned for speed and RABS. Link to comment Share on other sites More sharing options...

Ahh, OK...I thought that the speedo cable went to the transfer case in the Bricknose trucks. My bad. Now I see what they did. So you have a ZF-5 then, correct? Do you know if they did the same with the M5OD-R2 as well? Link to comment Share on other sites More sharing options...

Do you know if they did the same with the M5OD-R2 as well? The tailshaft of the transfer case. My truck came with a T-19, I swapped the Zf in. But the prior 1356 had this same location. I imagine all '80-'90 trucks do. Where else would you put it on a 4x4? Link to comment Share on other sites More sharing options...
