I acquired this lantern from Roland via the classifieds. He described it as "will need a little TLC but will clean up well", and for $10 I figured I'd give it a shot.

So, without further delay, here's the tear down and rebuild of the 335.

Start by removing the bail. Just pull on both side of the bail to get it out.

Lift off the vent.

Now this is a Canadian lantern, so all the nuts are metric. Use an 11mm wrench to remove the burner frame nut.

Now lift the frame straight up and take it off.

Use a 13mm wrench to loosen the generator nut.

Remove the generator.

Use a flat blade screw driver to remove the knob retaining screw, then pull off the knob and direction disk.

Lift the collar off the lantern.

Remove the spring clip that holds the cap for the pump shaft.

Now pull out the pump.

Unscrew and remove the air stem.

I clamped the valve assembly in a vice, protecting the brass with a thick rag. Turn the fount to unscrew the valve assembly.

The lantern is now fully disassembled.

I have a small plastic jar that I use to soak the brass parts in a bath of hot water and citric acid. Takes about 15 minutes, then a little steel wool and they become nice and shiny.

The burner frame is not too bad, some rust, soot and dirt.

I put the frame in a plastic juice jug with about a 1/4 bottle of toilet bowl cleaner and lots of hot water. Let it sit for about 15-20 minutes, then remove it and scrub it with some steel wool. You will be surprised at the results. Be sure to WEAR GLOVES when doing this step, toilet bowl cleaner is caustic!

While all the various parts were soaking, I washed the vent in warm, soapy water...

Looks much better now!

I removed the check valve with this super handy tool, then soaked it in some carb cleaner.

Here's the completely stripped down fount.

Here's the fount after cleaning with a soapy rag and rubbed out with some turtle wax. Big improvement!

Time to scrub down the frame. After rubbing it with steel wool, I go over it again with a toothbrush and hot soapy water, then dry and bake in an oven at about 200 degrees to completely dry it. Major improvement!

After soaking and scrubbing all the brass parts, it is time to start reassembling the valve. I've had issues with these F/A tubes. If the pricker does not slide easily in and out of the tube (it is tight or it binds), the lantern will be very hard to light, and it will burn dim. Make sure that the pricker is straight, and the tube has no blockages.

At this point I screw the valve into the fount, then remove the old packing material.

Use a 13mm wrench to remove the nut.

Here's the valve shaft and the inside of the packing nut.

Using a flat blade screw driver, chip out all the old packing. I also use a dental pick to clean out all the threads.

This ring goes on the shaft first. Take a careful look at it, one side is concave.

This side must go on first and mate up with the ring on the shaft.

Now put on the new graphite packing material...

Then the jam nut

And reinstall. Tighten this up as much as you can with your FINGERS, we'll tighten it up in a later step.

At this point I usually remove the valve assembly to put some thread sealer on the threads.

Doesn't take much...

Now screw the valve back into the fount. When looking at the fount from the top, the pump would be at 3 o'clock, the valve knob at 6 o'clock, and the filler hole at 9 o'clock. Put the collar on and make sure that the valve is not sitting too high. If it is, screw it in another turn until it looks like this.

Reinstall the generator by turning the cleaner knob to the UP position, then hook in the pricker.

Now tighten the generator jam nut with the 13mm wrench.

Put the burner frame back on the lantern, make sure that the tip of the generator is seated in the hole beside the burner cap.

Reinstall the nut using an 11mm wrench.

Put the valve knob back on....

...then the directions disk and secure it with the screw.

Reinstall the check valve

I LOVE this tool!!

Lubricate (actually, SOAK) the pump leather with neet's foot oil. Flex the leather, turn it inside out, and rub in the oil until it is nice and soft again.

Reinstall the air stem and pump shaft...

... and secure it with the spring clip.

Now on to the filler cap. Most times the seal in here is dried out and cracked, and will need to be replaced in order to seal correctly. I use a sharp knife and carefully cut/chip out the old rubber.

All the old rubber removed...

And new gasket installed.

No, it is not time to light the lantern yet. We must first tighten the graphite packing jam nut so it won't leak fuel while the lantern is burning. Fill up the fount about 1/4 full of Coleman fuel (CF).

Now, pump up the lantern about 5 strokes, while checking here for fuel. If you see fuel starting to come out here, tighten the jam nut about a 1/2 turn, keep doing this until no more fuel is seen. Now, add 10 more strokes, and check again for a fuel leak. If there's fuel, tighten about a 1/4 turn until no more fuel leaks out. Now add 25 strokes and check again for fuel. If you see fuel still, tighten a 1/4 turn again. I do this until there's about 100 strokes of pressure in the fount. Once I don't see any fuel leaking, I let it sit for about 20 minutes and then check again for fuel. Take your time with this step, you don't want a fuel leak here while the lantern is lit!!!

Well, 20 minutes later, no fuel leaks!!

Tie on a #99 mantle

Then burn the mantle. Do not turn on the lantern while a new mantle is burning in!

Once the mantle has burned in, light up the lantern. You'll see in this picture I had an extra flame coming out of the bail hole, this only lasted about 10 seconds, then went out on its own.

Globe, vent, and bail on, and now the lantern is doing what it does best, providing light!
