I’m working on a proto type military vehicle that has a humvee motor (6.2L) After much searching I found that the injection pump has a inlet screen. I think maybe mine is clogged. Has anybody changed/cleaned theirs with out removing the pump from the motor? It looks like the screen cover just un...

So my MEP 803 has always seemed to run fast. The minute I start it, it just roars away. The star wheel adjuster has no effect. I backed off the stop screw so I can adjust the star wheel more. Still no effect. The no load Hz is slightly higher than 60. I don’t suppose that is terrible, but I...

I’m trying to access the governor In the gear cover. One of the first things in the TM says insert common screwdriver through housing into ring gear. (to hold the engine from turning) so you can remove the bolt on the crank pulley. The housing doesn’t have any opening to do this unless they mean...

So I’m trying to do some testing on my mep803. In the TM, it says jumper a wire to the “cranking relay terminal AI”. Of course, they don’t tell you where that relay is or which terminal would be AI. (If there’s more than one) I’m guessing it’s just 24V +, but I don’t want to screw anything up...

I just got my Mep802a running and hooked up. I turned on a bunch of lights and fans and grinders and such. The percent current meter never moved. Is it always on or do you need to havme it configured a certain way?

I just bought a Mep802a. I was going over it and fixing a few things. I decided to drain and flush the coolent. I pulled both hoses and ran water through the rad both ways till clear. Then I attempted to do the same on the engine. It would not allow water through either way. I got thinking maybe...

Is there anywhere I could get good drawings with dimensions of a Hemtt truck? I'm mainly interested in the cab. (Outside and inside dimensions and angles of the sheet metal) There is a basic drawing that comes up when Goggling. But I would like a little more detail.
