So I worked at the Harley factory in Kansas City for 17 years. Spent a few of those years on the vrod powertrain assembly line. The transmission input and output shafts came from the supplier fully assembled. The engine case was split in half, we installed shift shafts and shift forks, then dropped in the assembled shafts with gears on them. My point is maybe same way at triumph? Maybe triumph was buying their trans shafts already assembled from a supplier? Triumph factory workers might not have had anything to do with it. Did triumph change suppliers at any time? When Harley first built the vrod they teamed up with Porsche, so a lot of the early suppliers were in Europe. I know cylinder heads were from France, lot of stuff from Germany. That changed every year. You can look at the outside of a vrod powertrain from 2004 and 2014 and they look the same. But inside there are 20 parts that were made by different suppliers in different countries. By the end almost nothing came from Europe. Sad to see really...The quality of parts coming from places like India was definitely not the same. So there is a chance that different year rockets have transmission parts from different suppliers.
