So I finally changed the rear main, and I messed something up. Before it was leaking a drop or two after a long drive, but now I have a major dripping leak from the back of the bellhousing after only running the engine for a couple minutes. I followed the directions per the -34 TM, but clearly...

Sounds good to me. Thanks everyone for your replies. I'll hook up a mechanical oil pressure gauge and see how it looks, and do the rear main and pan gasket this weekend. If the oil pressure seems low I'll do the oil pump while I'm in there, otherwise I'll leave it alone. I'll change the...

So you would do the rear main (which is leaking now), and pull the timing cover to do the front main even though it does not currently leak (might be getting to the end of its life)? Or leave it alone because it isn't currently broke? And you recommend reusing the water pump and timing set if...

At the point I have the oil pan and balancer off, is it worth pulling the front cover and checking the timing chain for wear? Or is that a bunch of unnecessary work on an engine that seems to run ok?

My M1009 leaks slowly from the rear main seal, and I want to fix it. I had a 350 SBC with a 2 piece rear main do the same thing, and I ignored it for 10k miles until it suddenly spat all the oil out on the road. So I'm trying to not make the same mistake with the 6.2 in my CUCV. I want to do...

I am looking at a Nordic Air 9k environmental control unit for sale locally. Does anybody have experience with these, or know where to find the repair TMs? I have tried searching for awhile with no success. Here is the data plate from the unit, an info brochure from the manufacturer, and a...

My M1009 had a manual glow plug switch installed when I got it. I want to bypass the firewall resistor bank, but I recently replaced the starter with a good 24V unit and I have no intention of replacing it again anytime soon. At least one of my glow plugs is bad, and I want to replace them all...

I got the new governor in last week, and the generator works great. If anyone has MEP-531 questions in the future, I'd be happy to help out. Once you take a look inside they are pretty simple machines.

I finally got a free sunday to pull the motor out of the 531 and take a look around. Sure enough, governor pieces were floating around inside. A new governor gear is coming, and should arrive this weekend. I'll post an update when its running again

I bet you are exactly right, based on the symptoms I have. I am a little sad that the engine seems to have puked the governor all over the inside of the crankcase with less than 3 hours on the clock, but it seems like that is the case. I guess it was surplused for a reason... I am up to my...

This was my assessment as well. Because I can "govern" the engine by hand with the springs disconnected and get it to run right, I dont think there is anything wrong with the engine itself or with the fuel system. I didnt think to pay attention whether the internal governor mechanism was...

My MEP531 starts up easily and runs, but it immediately starts to overspeed. The engine blows tons of smoke and pegs out the frequency gauge, and is obviously revving way too high. Clicking the "Stop" lever while holding the governor lever by hand, I can control the engine speed and get the...

I just picked up one of these, and have not got it running yet. Does anyone know what the connectors on the fuel lines are? I dont recognize them, and would like to get some matching fittings to hook up to the generator

So its been a long time since I updated this thread. A couple weeks back I cut the end off the sending unit and brazed on an extension, lowering the pickup several inches and deleting the filter "sock" on the end. I also bent the float rod so it sits level with my extended pickup inlet at the...

I do know the truck will run without a lift pump (or with a bad one), but I thought that could cause fuel starvation? IE if the injector pump has to pull vacuum on the filter and lines from the tank, it can starve for fuel at higher RPM. Supplying a few PSI from the lift pump pushes fuel...

I bough the truck in Salt Lake City, just over 4000 feet. Currently in Los Angeles, and not a real noticeable difference in drivability vs Utah. I am sure altitude makes a difference, but it cannot be as bad as what I am seeing (especially since the same problem exists at sea level, literally...

So I finally got a weekend away from work, and pulled the tank this morning. I ran the truck until the fuel gauge was just above the "E" line and I figured the tank would be about empty, but it was heavier than I was expecting it to be. Once I got it out on the ground, I emptied the tank out...

CUCVSRUS, I daily drive a 79 Corvette and have a 71 Honda motorcycle that I ride and wrench on for fun. This CUCV is 5 years newer than any other vehicle I have ever owned, and nearly a decade newer than the average of my old junk. I appreciate the input, and I'm definitely not opposed to hard...

Hey folks, I've been reading on this forum for a few years, and finally got my new-to-me M1009 a couple months back. Bought it just north of SLC Utah after wrecking my 82 K5 offroading, and road tripped it back to Los Angeles the next day. It did just fine for an old truck that had been...
