And that pump... Pulled it, and had the pump all but come apart in my hand. The top of the pump was barely hand tight.
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
Ok, now I'm confused...
From the TM:
If original shim thickness is not known or if fuel pump is being replaced, fuel pump must be timed.
Ok, so I'd need to time the pump...
But later in the TM:
3-14. FUEL INJECTION PUMP TIMING.
Each fuel injection pump is timed individually during assembly at factory and when an existing or new fuel injection pump is installed, it is only necessary to reinstall existing shim pack or a new pack of same thickness as original.
So which is it? Looking at the timing instructions, I'd say just throw the old shim pack back in and be done.
If you used a compression checker with a rubber end, just trying to hold it into the injector hole, it would blow your tester and hand up a few inches. diesels have a much higher level of compression. So yeah, you need a screw in tester.I *thought* it was running good.
It ran with 12.5kw load 2 months ago for ~30 minutes without a stutter. Little tinge of gray in the smoke with that load, but that's it.
I have nothing to compare it to besides diesel trucks for sound, but it didn't sound like a train wreck. Maybe I got a video...

Odds the rings got blown out by GP (or I) trying to start it with a fuel filter full of water?
Also, any leads on what size compression test kit this thing needs? Everything I see seems targeted to screw in glow plug holes...
Yes, use the old shims and move on.Ok, now I'm confused...
