First off, no pictures yet guys, I was just working to get it done, and I'll take pictures of the final installation.
First off, I was using the standard M35A2 kit to do the work, so various brackets etc didn't function in the 5-ton, but for the most part everything worked with minimal modification.
Installation of the heater was done on the driver's side fender, using one of the mounting plates in the kit. The internal parts worked fine, as the cab layout is the same as the Deuce. The air duct through the firewall was an issue, the hole punched in my M814 wasn't large enough for the vent diverter, this was fixed easily, and the parts bolted in place. Routing the duct work was a pain in the
.
Once this was completed, the fuel lines were ran. The pump and filter were mounted in the cab behind the drivers seat, or beside on the rear cab wall for easy access and some protection from the elements. The control box and vent controls were mounted centrally in the cab. The gearshift covers and transfer case covers mounted as required.
Overall it took me at least 8 hours to get it done and cleaned up. It tested perfectly, no leaks even at the compression fittings. Boy does that thing get hot quick though! One thing I found interesting, is that the exhaust duct produce practically no smoke at either the high or low setting running off straight diesel. The one in my M109 generally smokes at startup everytime, I'm guessing it's just well used
I'll try to get pictures of the installation. Far from perfect I would say, but safe and functional overall, and far better than the coolant heater. I will say that I'm going to try routing the air input into the coolant heater from inside the cab for recirculation using standard aluminum dryer duct. This should improve it's functionality quite a bit, the Lord knows it can use it when it gets below freezing!
