So pretty much wrapping up my process of getting the 803a going. Had it running on the load bank the other night and it will handle no problem 13500 watts resistive load. Throws the percent load meter to a little over 100%. My load bank is simply 6 4500 water heater elements I built it to load...

So I got into this project this morning. Pulled the sensor off the unit it did indeed have some metal shaving stuck to it as well as a good solid coating of rust on the sensor. I cleaned it up a bit and hit it with some 100 grit sandpaper clean up the rust layer that was on the end of the core...

Thank you that confirmed just what I was thinking was digging through the maint TM guess I should have just read the operators manual. Guyfang you are an incredible resource! The procedure outlined here makes a ton of sense. I almost went out there at 5 this morning to go test it but was 32...

So four years later I have finally got time to get around to getting my MEP-803a up and running. She purrs like a kitten now and makes power just fine and runs at full load no problem. I noticed however when I start the set the starter stays running until I let go of the start position and the...

Well stated I get so much joy watchin all my sets laboring away at 100% load and meanwhile holding engine temp fq and voltage. My load bank was pretty cheap just bought 6 4500 watt hot water heater elements. Took an old blown pressure tank cut the top off and welded in 6 couplings around the...

Nice wish I had a CNC bed mill. Does it have a fanuc 0m control on it? I almost bought an old leblond makino but it was having problems with a servo drive and a failing spindle bearing cost to fix it would have been many times what I was going to pay for it. Lookin at maybe a haas mini mill at...

Pull the NSN numbers from the TM and punch em into google. I found some on ebay as well as from other various places. Think Kraft power would also supply em for you. I was surprised by how much they cost. I have an oil seal leaking debating if its worth pulling it all apart to fix it or just...

Sorry to drag up an old thread but found this to be super helpful and wanted to add my experience to hopefully help others in the future with similar issues. 1800 Diesel thank you for doing a lot of the tracking down on the starting circuit I found the TM to be pretty much useless in helping me...

This is going to be a picture tutorial on the speed switch. There are two different kinds some units have an electronic version which has a more square enclosure and the mechanical version which is a round casing. This is going to be covering the round mechanical version I used to have a unit...

Im sorry to hear that :( We have all been there, be strong buddy! Not really in a hurry but would be great to have a pic and then put the dimensions on it. I would be happy to machine a couple out for anybody interested. Lee

Hum sounds like it could be a quick job or a royal pain in the ass depending how far I take it. When you say the seal is to small are you saying the crank surface is smaller in diameter Than original and thus the seal does not fit tight enough around it? And if one were to pull the crank and mic...

Fascinating I had no idea figured all the military genset were similar in this regard especially si ce this one was a newer generation. That's why I was a bit surprised at the drop from no load to full load compared to the ol 005a. Well I will regard this as normal operation for the 803a and...

+1 that would be great for the whole community. Sorry for the ambiguity you are correct motor runs nice and constant rpm. The rpm/fq drops about 3 hz from no load to full load. Thus is measured with my fluke multimeter on the main lugs. As to the 005a that is all I had to compare it to. The...

So I thought id throw this one out there and see if anybody has done this. My 005 is leaking oil from the front main seal. How big a job is this? Do you have to pull the whole motor to do this or can you just leave it in place and maybe lift it a bit to get the job done. Ive personally never...

That's awesome I would love to see some pictures and get some measurements so I can machine one out. Any way Guyfang was right governor seems to be okay with this unit had to tear down one of the fuel pumps but the rest of them were free and working. Got the unit to fire up blew a lot of...

Perhaps I'm looking for a problem where there isn't one. I had just assumed that it would probably have a problem this thing has not run in the better part of at least 5 years with a lot of rust on everything. As for the gage you guys did not even have one in the military to service the units...

So as the title suggests I was reading through the TM on the governor adjustment procedure as it is outlined in the TM. So I have been searching for anybody that has done the governor adjustment per the TM. It mentions you need to have the governor setting gage (317-50115). What is this gage can...

Glad it helped somebody hows your unit run? Lee

Just came across your thread. I actually do have an entire motor that over heated and had some issues. Any way long story short I put a new motor in the set now runs great. The shaft you mention should be on the timing gear on the motor. There is an inspection plate held on with four bolts...

What I would check first if the 006 is not firing is if it is getting fuel? First is there fuel flowing to the actual injector pump. Take the hose off and diesel should just start running out of the hose it is gravity fed by a tank on the left side of the unit (the day tank) which the fuel pumps...
