Hello friends, I´am Victor Silva (Vicho), builder of the PatoV6`s BW/D20 doubler. This idea was born to address Pato`s concern to achieve a higher Crawl Ratio in his Ranger, but with the idea of changing as little as possible in the rest of the truck (didn’t happen like that…). So, looking into the options, we decided that the best option was to use a Dana 20 Early Bronco transfer case, because of its ruggedness, size and configuration ideal for the Ranger. And opening the the possibility in the future to go into twin stick (…still does not occur, until Pato learns the rest of the combinations… hehe). So we found a D20 in a very good general state and began the task. To keep the length of the package, we chose to use the front half of the case of the BW and make a plate separator that bolted in both cases, so using the same shaft entrance to the D20 and making accommodations for the entrance of the bearing D20. We manufactured the guide and support bearing resemblance to the original set of EB too, once ready for this and taking cases coupled came the task that was more complicated…turning the electric drive of the BW drive to a mechanic. Unable to find another Non Electric donor, we had to produce the elements needed to trigger the whole reducer. For that, we manufacture a shaft that would be able to move the fork. After a couple of tests, this proved that it worked perfectly. So we drilled the case for getting into the shaft, and step down onto the pin and spring that allows it to be in the hi & low position, so we get two boxes work mechanically. Then, we reassembled the whole body into the truck , adjusted the driveshaft and installed the levers. The new transfer cases got just 2" more original length which allows them to be installed without changing any other element as fuel tank, brakes lines, etc…, the result was very good, achieving a dramatic increase in the benefits of the Ranger, and best of all, leaving the minimum alterations onboard.
