From MO for years but was born at Offutt. My Dad was in the Air Force. Clayshootr, is that a 720 diesel? I have a 720 LP and a few others. Even with a tarp, the worst thing I can think of concerning long term outdoor storage for any engine/machine are mud daubers. They cost me a pinion...

I'll look for a way to install a valve stem into my jig. Thanks Jim.

I'm finally catching on, I hope. With my gauge check valve is at the connector and the relief valve by the gauge. I was thinking about it today and first thought the location of the check valve didn't matter. The cylinder has to compress the air on both sides, which is true on the first...

Jim, Very good point, I thought about it briefly but never really considered it until your post. I bought the gauge assembly which does have the check valve at the gauge. My test fitting is made from 1/8" pipe fittings so not a lot of volume but with the hose, air fittings etc it all adds up. I...

$65 includes the rebuild. The only knob I could find is the reconnection switch knob. Are they the same? Here are some pictures of my MEP and the compression test jig. The pictures were taken in my shop. Should have taken them with better lighting when it was outside. The jig is build with...

Jerry / All, I've been working on it for the last couple of days and here is what I found. I did find in the TM, #1 cylinder is adjacent to the blower end. I built a glow plug compression test jig; the cylinders were low 290-320 on the dry test. TM says 375psi is minimum but on a warm engine...

I pulled the cooling shields off today and removed the muffler. To my disappointment, no restrictions. I found the exhaust ports of the two cylinders one wet with fuel and the other dry carbon soot. I started making a compression test adaptor from one of the old glow plugs. Compression test...

Grega, You could be right on the money! You comment also hit me square between the eyes. It has been sitting a long time and of course I cleaned a fair number of mud dauber nets out of lots of places but I didn't check the exhaust system. Could simply be an exhaust restriction. Reminds me...

Hope everyone is having a good Christmas season. I've had a little setback on my MEP-003A project. I had the engine running and found the VR issue but never ran it very long. I was waiting on glow plugs which I finally got and installed today. (let me know if anyone needs any, I had to buy...

No... I don't remember the actual voltage drop but I will order the transistor and replace it. After working on the board do you normally follow the recalibration process?

Thanks for your comments, I removed the Q3 from the circuit and tested with a Fluke in the diode test connection. Emitter to base, base to collector junctions tested good (flow in one direction not the other) and I didn't find any conductivity from emitter to collector. I know this only...

First of all, I thank you all on this forum for all the information I have learned about the MEP units. This is my first post but I have devoured tons of information and you have answered almost all of my questions. I bought the MEP at a farm auction which had been sitting in a barn for a number...
