• 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.

Speedo Cable issue


Just installed a T19 and D20 into my 1977 SII - 4cyl 1bbl. It works just fine, seems a bit better throttle response than the anemic 3 spd that was in before.

New issue: the speedometer is not working. when the speedo cable is hooked up to transfer case, no go on speedo. I tested the speedo with a drill gun - speedo works just fine. when connected to tranny,nothing. Attached picture shows the outlet at transfer case fr speedo cable. I am wondering: is it possible that the round part inside is broken? is it plastic? does this require a removal of the back end of the transfer case to remedy?

Also, the large grey object? I am guessing it is a "reducer" of some sort?

let me know and thanks?



this may be a dumb question but, I have to ask:

is it possible that the speedo cable is not turning the correct way. When i have a drill gun running the speedo cable in reverse (counter-clock wise), the speedometer shows that it's working. The speedo gear that is plugged into the D20 transfer case is turning clockwise. or am I missing something here? DAMN!

Did the 3 speed have a"reverse (CCW)" gear, and the 4 speed have a forward (CW) gear turn?
