Hi there,
I am currently shoulder deep in a 5600 rebuild and have a few questions about the powerlube upgrade I've heard and read about that the big name re-builders are doing. The limited information I've found suggests that drilling holes in the first gear can greatly assist in lubricating the rear mainshaft bearing and significantly prolong the life of the unit. Does anyone have any information or pictures of this or feedback on it's effectiveness? Or is this a patented modification that one could get in trouble for revealing?
Any help is greatly appreciated

This is the best info I can find so far:

Turbo Diesel Register - Issue 67

Page 84 has a little bit of info, but apparently that method is only a precursor to a more effective one. Seems like this may indeed be a trade secret
