That is one heck of a chunk to bring home! I snuck a D4 5T home and my wife never even noticed in our small yard which has me thinking...😂 Nah better not...

I used fo work on large gas engines in my apprenticeship. Almost all of those series were NA except for one 398 that I remember that also had large air to air coolers. They were a pretty darn good engine. Not much for fault other than almost all of them leaked. I guess a few hundred thousand hours on the block and numerous overhauls will do that. One 398 we overhauled needed a cam and we had to wait I think more than a month for it to weave it's way from Singapore I believe. There were running on net gas of varying degrees of quality but they all seemed to do pretty good. Not the burned valves of the smaller 3400 series engines. When we went to service those, we packed a head and associated gaskets. They did not hold up at all in my experience. They burned valves constantly and generally suffered much shorter life with cylinder and ring wear in general. Now, the 3500 series, that was an engine! Amazing run time with those. Once in a while we may replace a head and they eventually all wear out, but they are a great engine.
Also I remember when BCIT took over the old Finning (Cat dealer) facility down on Great Norrhern Way in Vancouver, they left a D398 gen set they had for standby power. It had not run in many years and when our class fired it up, we ran the fuel return into 20L pails. Well there was alot of muck that came out of there! Might want to consider that.
I often got the heebie jeebies when working on gen sets after a big job. I had one recip compressor come apart when we put a load to it so I am still a little gun shy. Is there any reason one couldn't disconnect the throttle linkage and "play God" sort of speak? Generator not online of course.

Just trying to see if I can post or not in this thread or to see if it is just me with poor computer skills.

Ok, I think I figured out my issue. I was trying to go right to the box and start typing ........... wrong , I had to hit the action box first pick one of the three choices and then go and type in the big box. Whew.......... I will get this figured out yet. Just so you guys and gals know ,I am a lot better at stuff with grease on my hands.

Here it is running at home after getting the governor adjuster. I did eventually get the Woodward set to 600RPMs cause that is what I run my blade at on the sawmill.

This was the spot I had to dig out so the drive shaft wasn't at to much of an angle
