Over the past year, maybe more, I have been working on some smoke grenade launchers for the Museum's M551. It is outfitted nicely, but it just looked nekked without the launchers.
I was attempting to just go off pictures to try and get measurements, but I was not happy with what I was coming up...
Those two pics above are of an M20. Kinda the same, but not. I would prefer the M20 because it has more room for a tall old guy. The M8 isn't fun to get in and out of.
Let me look in the library at the Museum. @Mullaney , @JasperM925A2 , what page range is needed? If the TM is there, it will be loose leaf, I can scan to PDF and send it off to the TM section.
Return is only drops. They are pintle style injectors so after the line pressure drops, the pintles close, the only flow is very minimal, almost residual from inside the nozzle, not flow from the pump, to cool/lube the innards of the nozzle.
It is part of the "tamperproofing"
With the nuts missing could engine vibration over time have worked the screw and throttle shaft out of alignment? If so what direction should I turn the screw to get the angle between idle and full throttle back to 32 degrees?
It is going to be the screw...
Oh, again, the screen in the pump, the one under that big azz flat head screw, is only there so that in case of a catastrophic fuel pump failure, the debris from the pump will not get into the injectors. It isn't a maintenance item. HOWEVER, in the case of something sitting and getting gooed up...
Sorta. The system, PT, Pressure Timed. The pump makes flow only below a specified RPM, and boost when turbo charged. The injectors take the fuel in, trap a specified amount when the plunger is forced down out of the metering position and then passed down through a check ball equipped passage in...
Looks like a project fer shur! I know where there are some doors, possibly a PTO, a complete dash, maybe a starter. Wonder why the fan hub was removed? At least the pump is still there! I do see a couple of holes open to atmosphere.
