• To ALL forum users - As of late I have been getting quite a few private messages with questions about build ups here on the forum, or tech questions about your personal project. While I appreciate the interest, sending me a private message about these topics distracts from, and undermines the purpose of having a forum here. During the day I wear many hats as a small business owner-operator and I work tirelessly to provide the absolute best service possible to you, our valued customer. When I created this forum I rounded up some of the best minds I knew so that any tech question you might have could be asked and answered by either myself or one of my highly experienced moderators, this way the next time this same question is asked the answer can be easily found and utilized by the next IH enthusiast having the same question. This allows me the freedom to run the day to day operations of the business and minimize the impact to shipments and shop activities that these distractions can cause. It is of the up most importance for me to complete the daily tasks in order to best take care of you our customer, all the while providing you a forum to get the level advice and input you have come to expect and deserve from the premier IH shop in the country.

    So with that I ask that anyone with a question about one of our build ups or a general tech question to please use the forum as it was intended. I am absolutely available by telephone to answer your questions as well but at times may direct you back to our website to better field your question or questions. Most other private messages I will be glad to answer for you.

    Thank you for your understanding.

Timken T-32 transfer case


New member
I've got a rare (1 of 932) 1954 R-160 4X4. These trucks had a massive Timken T 32 transfer case. The only PTO option is a full engine torque rear-facing unit that I'd love to get my hands on. Not to mention a basic rebuild kit for the T-case. Any information on these transfer cases and on the PTO unit would be greatly appreciated.

On these trucks, the diffys are both offset to the passenger side, so the transfer case PTO splines directly onto the back end of the input shaft. Great for the Bell Telephone trucks that drilled the holes for installing new telephone poles, for example.

In the attached drawing of this unit, the input shaft is top right (well, one of the two t-case shifters is at the very top right), the PTO mechanism is top left, and the front and rear output shafts are at the bottom.

Update, looks like the T-Case in my truck dates from 1963, so is not orignal. The original would have been a nearly identical Timken T32. Rockwell bought out Timken's transfer case production, and renmaed it "Rockwell Standard" in 1958. THey are similar enough that the IH part number stamped on my 1963 Rockwell is the same as that listed in the 1954 IH R-160 4X4 parts catalog for the Timken transfer case.

I'm still interested in anyone who has the PTO unit described in the original post. Or that can confirm whether or not the PTO units from later Rockwell T-223 T-Cases are compatible.
