Coleman Peak One 442 Rebuild

This is the first backpacking stove I ever bought (Spring 2001, probably). And my first liquid fuel Coleman appliance. I had a fuel leak below the valve, so it’s time for a rebuild.

The operation of all these pressure stoves and lanterns is basically the same. Liquid fuel (white gas or unleaded gasoline for this unit) is stored in a tank. The tank is pressurized with a hand pump. The fuel flows through a generator which is heated by the burner. As the fuel is heated, it undergoes phase change from liquid to gas. The gaseous fuel mixes with air to create an efficient source of heat. The lanterns appear white because the heat of the flame causes the mantle to become incandescent.

Every liquid fuel appliance requires a moment to warm the generator before they really work well.

Remove the pump by pressing down and turning counter clockwise. On the opposite side, remove the fuel cap.
Unscrew the valve stem from the check valve
Remove the generator clamp with a Phillips screwdriver.
Loosen the nut holding the generator onto the valve.
Take off the generator and the pot supports.
Take out the center screw and the burner, rings, and bowl lift off
Three Phillips screws hold this assembly to the top of the font.
Unscrew the valve from the font. You may need a vice to hold the font.
Keep your pieces in order for ease of reassembly.

Clean all the pieces gently and reassemble.

With a bachelors degree in history, I turn wrenches for a living. I’m most at peace when I hear the wind in the trees or the gurgle of a brook. I’m a believer in the Renaissance Man, as epitomized by DaVinci engineer, artist, soldier, statesman. As Heinlein said, “A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyse a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.”
