U.S. Gear Dual-Range Transmission and D-Celerator Exhaust Brake

Let me start by saying that zero credit for this belongs to me. Courtesy of various members on Oilburners.net, I've gotten my hands on various installation, operation, and troubleshooting documents for both the Dual Range auxiliary transmission and the D-Celerator diesel exhaust brake. These were manufactured by U.S. Gear, and both have been discontinued, regrettably meaning that parts and support are no longer available for either item. Given that, to the best of my knowledge, reproductions of these documents are no longer availabe from U.S. Gear or from any other source, I wanted to make these documents available to anyone who needs them on a fair-use basis. I do not own any copyrights to these documents, and if the copyright holder(s) feel that this posting is in violation of any copyrights, please E-mail me and I will remove these immediately.

With that said, please click on either link below to access what I've been able to compile. Please note that this is everything I have. I do not have any sources for replacement parts for either model; in fact, if you find anyone who does have any replacement parts, please let me know and I will add that information here.
