So was mislead by operators manual, and specification sheet for machine. Found tag on top of valve cover and unit is a 4LE2-622683
Ran unit couple hours on Friday, and this is what I have observed. The engine was about 50 degrees Fahrenheit on start up and blue smoked and unburn't fuel out of exhaust for 1 minute until I started to put light load to it. As load increased to 50 percent, I had to keep adjusting speed on governor to stay above the bottom shutdown speed (58 Hertz). Of course there is no smoke once up to temperature. At 58.4 frequency or so it did shut down on frequency alert. Ran for more than 1 hour at 59.3 frequency and held load well. However when I dropped the load one breaker at a time the frequency increased until it shut down at 63 frequency.
My thoughts are that the injectors are done at 12000HRS. That was why it fueled so poorly on start up and smelled bad fuel out exhaust along with oil off of cylinder walls. When you drop the load the governor does not pull back the fuel enough, and since I had to increase the vertical down screw on the governor to maintain 59.3 frequency, it then wants to settle down around 63 which is 5 second shut down. The warning light was on the full time of test as it comes on about 0.5 off of nominal 60 frequency.
This unit has not had valves done either from what we can see. So plan to do valves and change injectors to clean up the burn.
In answer to your question( the pumpguysc ) the long vertical down screw turns the big lever. Is that what you would call the droop screw? Behind that lever is a small lever that if you turn it left will shut down the engine.
But also touching the big lever is a small horizontal adjustable screw and nut that is not sure its purpose.
Maybe some kind of buffer screw.
Behind the steel plate is the only way to get at that screw. ( Horizontal screw )
There is hiding behind the steel plate that has to be ground off from what it looks is another screw that faces inward into the block with a jam nut also. Maybe it comes in contact with the fuel rack?
The controller inside is a IntellLite MRS 19HE to answer your question MarshallPowerGen.
Injectors and gasket to adjust valves is $1600 Canadian from Isuzu dealer.
Would probably be a good start, and maybe needs some governor work also. Will need to get a manual eventually, or before I dig into the governor. Company got unit cheap at Auction. Not sure what they will do. Any thoughts on this update.
