HOW TO: 4M40 Boost Compensator Adjustment

WARNING: please don't copy anything in this video if you don't understand the basic principles of how a mechanical diesel pump works, and the effects of adding extra fuel to a diesel engine. You do it at your own risk.
This video shows how to adjust the boost compensator on a 4M40 2.8L Turbo Diesel Pajero. This process will be same/similar for Triton and Delica.
I recommend you have boost and egt gauges before messing with boost or fuelling.
Any questions, just post in the comments section. Thanks.
P.S. I made a slight verbal mistake in the video about more fuel on the steeper ramp, it's the opposite lol. But I was just trying to explain the difference of each side of the ramp. Sorry.

EDIT: I’ve done numerous other pumps after this one and found the ‘o’ in different spots. I think this is if the pin or diaphragm has been replaced. So you may need to work off the ramp angle with a bit of trial and error.
