Yep!

Been 7 more days since I last ran the truck. The hose directly from the input of the first fuel filter to the tank seems to have taken care of the problem. Truck started right up without any problem. So it looks like there is a problem with one of the hose/pipe connections, hose itself or the...

Well the saga continues. It has been 9 days since I last ran the truck (M931A2). Started right up and ran for about a minute or so and quit. Primed and it ran very well. So today I ran a temp 1/2 inch hose directly from the ball valve on the large filter input to the left tank (remember the...

Does anyone know if GP is using the same location for load out as did GL for their trucks at Sparta/Ft. McCoy. I have picked up many trucks at McCoy from GL but never picked one up from GP. I have heard that at some locations GP has an off post location. Thanks

It has been a week since I last shut down the truck. Started it today and after a minute or so it quit. So the check valve did not solve my problem. The check valve itself did what it was supposed to however. So the check valve is a good deal if you want to be sure to prevent back leakage at...

The return fuel check valve should fix it I would think. Your problem is very similar to my problem and the check valve did the trick. I had replaced the transfer pump with a new one earlier. Were it me I would replace the transfer pump anyway as they are a mechanical unit and they get tired...

Got the adjustable check valve today. Installed it, purged air from system and ran truck for a few miles. Everything ran normally. No excessive smoke when I started it or when it was running. I will let the truck sit for a few days and start it and see how it works. Will get back to you...

That could well be Will. As we all know Cummins is great for upgrading parts etc. When I was replacing the transfer pump on the 8.3 I came up with around 3 or so numbers for the same basic transfer pump. So I called the Cummins distributer to get the latest number. When I was cleaning the...

Richard this is the standard return check valve used in most 8.3s. There is another style but I am not sure if it was used in the military version of the 8.3. Part number for the one used in the military 8.3s is 1-417-413-047 You can see what the adjustable replacement I am going to use looks...

Crazy..........While waiting for the adjustable check valve to get here I decided to remove the existing one and take a look at it. Looked to me like there was some crud in it. Took the brake cleaner and cleaned it out. Some crap came out. Also used a small plastic rod to push back the ball...

The most important thing to take with you by far is a lot of money. I recovered a M1070 HET from Ft. McCoy, WI to the southern Black Hills in the dead of winter. When we were coming into Sioux, Falls, SD the Detroit blew an injector. Just the bill from the Detroit Company shop was $2200...

That should work well I would think.

I am trying to make this thread more searchable. Change the title Clinto if you can come up with a better title. There are a few threads about a problem with the return fuel check valve on the M939A2 series. The check valve is the same one used on the older Dodge Cummins 5.9 pumps. And there...

Does the switch you got close its contacts at 60 PSI ? I would not solder wires to the existing contacts as you might melt the plastic. Causing a leak or just a bad contact. Use the correct wire connectors on the switch and a couple of short wires with Packard connectors on them. I have...

Bill was one of the last of the old time folks. He believed that you were only as good as your word. If your word was no good, you were no good. Not many like him left sad to say. Rest easy Bill.

I can always drive the M8109 over so you will have a place to live..............after bird lady (wife) does her thing. Have you had a call from the police yet? I am not sure that Galesville is ready for the big boom.......hahahaha. Now to find a good M38A1 and turn it into a "C" model. Would...

What is the plan for getting the truck from Seattle to Alaska?

Found one in a local junk yard. They had a couple of gasser G742s there. All are now gone from around here as a few years ago a portable crusher came through here and took everything. I mean everything.

They are very quiet, the quietest of all the deuces. How does your intake manifold look? On my M34 it was cracked at the heat box for the winter/summer damper, it was a common problem. Was a big chore to find a replacement.

Some trivia on the part numbers for the M939A2s transfer pump. Actionpaintball is 100% correct on his tracking the numbers. The 4988749 is the correct number at this time. There were previous numbers used and many are still out there and will probably work ok but are not the latest and...
