If you connect the exhaust lines to atmosphere (weather), then you just need combustion air volume plus an additional air flow amount for radiated heat removal. Just don't hang a bunch of hard piping to the exhaust manifold pipe street elbows or you'll end up cracking/breaking the muffler. Use...

I assume you already know this but the MEP-003A has an oil cooler mounted inside the fan housing. As long as your generator house has good ventilation, you shouldn't need to install an additional cooler. Set up the exhaust fan high and air supply louvers down low and at opposite ends of the...

Ask for Robert at 888-687-0539. This is a Yanmar dealer in Baton Rouge, LA. He will need your engine's model number. https://www.dieselpartsdirect.com/yanmar-diesel-engines

If you're getting the same running condition with the known-good injector, this points to any of the other items mentioned. Just go through the check list, not necessarily in the order provided, maybe the easiest one first, such as intake obstruction, timing, valves...obviously we're all hoping...

I'm still learning about these engines myself, but can offer a few things to consider. 1. Check the fuel plunger on the injection pump as it may be sticking a little. I've only seen these fully stuck and they have to be freed up. Since your engine is running at lower speeds, this could be a...

If you're unable to locate a good unit, I have a few MEP-003As in my shop. Slowly working through them one at a time. Right now a couple MEP-004As at the front of the line. Location FL panhandle.

I'm with you on the MEP-003A--have operated the same unit for over 20 years and through many hurricanes down here and it's never failed. However, I'm assuming if an 803 wasn't enough output for his business, then the 003 wouldn't be either. It seems he's figured out the business load to be...

I would recommend an MEP-005A, rewired for single phase. Then you'll have 120/240 volt and using what I've been getting out of MEP-004As after single phase conversions, you should get something between 33 & 35 KW continuous. Also, I believe the MEP-005A is a little easier to troubleshoot and...

Sounds like you may have found the culprit. Shy of taking the injectors apart, you can try soaking them in diesel a few days and then install the high pressure lines onto the injectors (out of the engine) and do a "bench test" to observe fuel spray/atomization quality, while cranking . Just...

I know this may be obvious, but are you using the pre-heat function? Even in warm weather these engines don't like to start unless I use the pre-heat. Once they've been running awhile, a re-start is not a problem but for a cold-iron start up they usually like the pre-heat for at least 30-45...

Didn't notice there was a TP for the shutter assembly--should've dug into the TM a little deeper. Hopefully tomorrow I'll get on that. Tried getting a couple hoses today at Motion Industries, but they have closed their counter service. so....I'll have to put the old ones back on so I can do...

Was thinking about using drano to clean this thing but used mechanical cleaning method along with a follow-up with brake cleaner. I may have to replace the thermostat assembly though--mainly due to lost material from corrosion IWO the gasket surface. About half the width of the mating surface...

I've only been running this one for short periods to run a compressor or welder every & then. Glad I discovered this before I did a 4-hour load test! This stuff almost looked like gravel from Pensacola beach or something--crazy stuff!

Was attempting to drain the water from one of the units in work--setting up for a cooling system flush. After opening the pet cock, no liquid came out. Pulled the lower hose and then removed the shutter control thermostat housing and found it 95% clogged with mineral deposits of some sort...

Didn't get much MEP work done today...rainy morning and I ended up running the roads today picking up some supplies and such. I didn't see any numbers on the CB2 though. Meant to ask if this one is possibly from an MEP-006A, does it have a higher interrupt rating and therefore I should swap...
