NOW THAT MY M-38 IS IN THE RE-ASSEMBLY STAGE, MY PARTS SHELVES ARE BECOMING MORE SPARCE AND I'M RE-DISCOVERING SOME PARTS IN BOXES THAT I'D FORGOTTEN ABOUT-BECAUSE I DONT INTEND TO USE THEM. NAMELY A NEW STEWART WARNER SOUTHWIND 978M H-24
COMBUSTION HEATER AND STILL IN ORIG BOX THE ELECT FUEL PUMP,
CONTROL BOX AND WIRING HARNESS. ALTHOUGH I DONT INTEND TO USE IT, I'M CURIOUS ABOUT HOW/WHERE IT WAS TO BE INSTALLED,
HISTORY OF USE, ETC. (IF IT'S SO COLD THAT I NEED A FLAME THROWER IN THE CAB OF MY JEEP, YOU'LL FIND ME IN THE LIVING ROOM IN FRONT OF THE WOODSTOVE). ANYBODY?? THX, RICK
That is the most efficient heater built for the M38. It is mounted outside the windshield on the cowl in front of the driver. A duct ducts the hot air thru an adapter that replaces the windshield's lower center vent panel. A distribution duct on the inside provides for dispersing the air to the feet and for defrosting to the windshield.
I have a couple of them. They do require periodic service and inspection to insure fuel pressures are correct and the burner can integrity is satisfactory. _________________ Wes K

i'll e-mail pics direct to you if you like since i dont have the posting stuff
figgered out
Rick's heater assembly and parts. The heater may be from a different vehicle due to the odd arrangement of the main and combustion blowers. The M38A1 installation has the electric motor of the main blower pointing upward.
That's not a very common question. The quick answer is from 0.006 in lo heat to 0.029 in hi heat pounds per minute. Figure 7.5 to 8.0 pounds per gallon of gas. _________________ Wes K

Actually that's not all history. These Stewart Warner (Southwind) heater and Janitrol's heaters are all still alive and doing well in light aircraft. I've been maintaining the 940 series for 20 years now. They are sensitive to a correct fuel pressure setting as well as a correct amount of combustion air flow. The older units with stainless steel burner cans need a periodic leak down check to prevent their deteriorating enough to give you carbon monoxide poisoning.
The modern units have ceramic combustion cans. _________________ Wes K
