If you pull the pink wire and it stays running, then the trouble is not on the truck side of things. A rebuilt pump did the same thing to me when I installed it a few years ago. I put another solenoid in and all has been well ever since. Just pulling the top cover of the IP and swapping the...

Stock distributor? Timing set correctly? If yes, then maybe a single pump on a cold day. Otherwise it will fire up like it wants to go play. Mine would flood if you pumped more than once It seemed.

The Holley needle and seat will foul if you say "Dirt" within earshot of the truck. I suggest pulling the float bowl, blowing through the needle and seat, put it all back together and see if it is better. If everything else is correct that will probably fix it. I had 2 inline filters on mine...

All of the civilian 6.5 fans should be for a serpentine belt setup. If you have that part figured out then, yes it will fit the fan shroud. I have a Duramax fan on my Cowdog Suburban with the serpentine belt and stock 1987 6.2 fan shroud. I have no clue about a HMMWV fan and fan clutch with...

3 things have to happen to start the engine: Glow plug circuit activated and given time to function IP fuel solenoid given power Starter motor engaged Maybe a 4th thing with the fast idle solenoid needing depression of the throttle to work.

Yes, that is the procedure. There was only the direct drive starter motors then so shims were used.

Is yours a reduction gear or direct drive starter motor? The redux units almost all say DO NOT SHIM. The CUCV and HMMWV manuals have a great part about how to determine if you need to shim and how much as well.

The stock M715 axles are considered “weak” by modern built axle standards. I have a Detroit locker in my rear axle and did dry pavement burnouts with the 38” tall Michelin XZL tires. The ”weak” part is the outer u-joints of the front axle. If you turn the wheel full lock to one direction, have...

It is easier to swap in a column with a good wiper switch in my opinion than changing that switch. Check everything else twice as already suggested.

I know options are many. I had a Big Block 396 in mine for a few years and a 6.2 diesel for the last 9 years. You asked about starters and seemed determined to use your Chevy engine with everything else being left alone. So I didn’t do a sales pitch about anything but the 24 volt stuff. If you...

I also have to agree that the Tornado is a good engine when operated at reasonable rpms and good maintenance. I got rid of mine because of massive rear main seal leakage.

Does your engine have the bell housing starter mount or the block mount? Here is a bell housing mount 24 volt: https://www.amazon.com/Rareelectrical-COMPATIBLE-CHEVROLET-10465320-10455344/dp/B07NGSFPQD If yours is block mount. Figure out if it is a straight or angled bolt mount. Then search...

You can get a 24 volt starter.

The turbo does amazing things to the diesel engine. Installation is really very simple if you get the entire kit with the exhaust included. The hardest part for a stock 6.2 conversion in my opinion will be getting the set screw out of the block for the pressurized oil feed. Everything else is...

I towed the M715 behind the Cowdog to the Rally last weekend. Here is part 1 and 2 of a video I made during the drive showing the Compushift display, boost gauge, EGT gauge and water/meth controller: I couldn’t get it in the video. But, my coolant temps would rise to 215°-217°. Then my...

I typed before thinking. Thanks for the correction on the temps. I was thinking exhaust side. OOPS.

I don't know the output size of the turbo. I do know the cross over manifold part has an inside diameter of 2.87 inches. That is such an odd size for a pipe. The single O-ring is very, very thick. I would imagine the turbo output is no more than 2.5 inches. Since the air leaving the turbo...

I have another 40 minutes of convoy driving I could post but it is just me driving behind the M725 so I left them alone.

Here is the M715 cam of the ranch exit until just before the M113 died:

Here is the M715 cam from getting going again from the M113 stopping to the M113 getting under its own power again after an impromptu pull start.
