Anyhow, what I mentioned below is same as the Pelican Parts advices on their technical article regarding removing the two tensioners (I remebered wrong the locking of both vs. only one exhaust cams - both is the right answer):
"With the camshaft timing properly marked and the intermediate shaft secured, it's time to remove the two tensioners that pull on the flywheel-end sprockets of the intermediate shaft. The first one to remove is the tensioner for cylinders 1-3, which is located to the right of the flywheel area and is shown in Figure 77. Next, remove the tensioner that tightens the chain that connects the intermediate shaft to the crankshaft, located to the left of the flywheel area (see Figure 78). Be sure to have an oil catch pan ready when you remove these two tensioners, as oil will spill out. Next, remove the center nut from the bearing. "

Interesting is that this above is seen as not a good practice

You need to be aware that when IMS retrofits all began, Pelican published "their" procedure designed to save the DIY market money, but the end result was a disaster, with far too many retrofits that went bad due to their "special procedures", some of which required engine disassembly to repair. Jake Raby developed a proven method which is the only one LN Engineering recommends to this day. We have used that exact procedure on innumerable retrofits, and never had a problem. Stick with the LN procedure and ignore Pelican.
