    Default Spicer 5 speed question

    I was wondering if the airlines that go to my transmission just control the poppet valve? I will be replacing the transfer case in my xm818 and putting an air switch in the dash so I won't need the poppet valve anymore. I would like to remove the airlines from the transmission just wasn't sure if they were there for any other reason. Also in the T-1138 transfer case other then the airline to activate it does it need any other air connections? Replumbing my whole truck air system, brakes, fuel..... so just trying to plan out what I need and what I can eliminate just trying to keep it stupid simple the less I have the more I like it. Thanks.

    The air lines on the trans control the forward and reverse sprague of the transfer case, so yes you need it all.

    Chris, he is replacing the stock T-138 TC with a T-1138 from the M939 series. So there are no more sprags to be controlled/shifted; just one dash-mounted air switch needed, and a single line to the new T-case.


    To Olly: check out this thread, if you haven't seen it yet.

    On that thread. The 809 series trucks use a companion flange on the transmission side. You can use a companion flange on the transfer case on the 939 as well. The flange swaps with the stock mechanics style easily. I will try to find the part number. This will save you several hundred dollars not having a shaft made


    It can be expensive to make a morph joint with mechanics style and 1710s.

    You can see the flange on the t1138 here.

    NSN 2520-00-734-6802; part# A3280G1957

    Meritor uses either 5WCS32-37A or A3280G1957; Navistar has it as ​99023R11




    Olly: Do a google-search for "Navistar ​99023R11" and buy that flange NOS for $75, free shipping.
    Or maybe post a WTB-ad, here in our classifieds. A good takeout, out of a 5-ton diff.; -transmission or -TC-output (they are all the same part#) might come out even cheaper...





    EDIT TO ADD: The above part# is only good for the T-138 TC; not the T-1138! (See my post #9!)

    If I remember right the flange that goes for the front output on the t1138 is the one you would use for the input on the Jack shaft. Part # A-3280-U-7535

    I got it from swampdonkey. I believe that was his extra. Maybe it's in my old CAT thread

    I stand corrected, Wes! Your part number is right; mine was wrong... Just confirmed: the flanges of the T-138 and T-1138 are the same size but they have different splines.



    Sorry Olly, that suggested part in my post above WILL NOT WORK for a T-1138!
    FWIW, both, front and rear output flanges of the T-1138 are the same.


    One possible source: (Military Truck Parts), NOS at $66 +$15 sh.
