Trying to resurrect mint condition curtain burner. I've read all the complaints/hazards. Attempting a test, while the primer was invisibly burning off, I failed to notice flame burned out, before igniting the burner. I concluded it too risky and proceeded to drain the fuel, when the stem pump pin fell out. Convinced myself I hastily gave up. How hard could it be to figure out how pump stem shaft attached to the piston assembly. Took days to come up with this lingo. Apparently it takes an o ring? Tried one but it didn't fit. Has anyone made this repair and where might I find parts?

I think your wasting your time. Parts haven't been available for a long time as you are probably finding out. Maybe someone has one still laying around that you could get the plunger and rubber cup. I actually threw mine out a few months ago in a clean out. There are some that have converted it to gas. Might make a nice project. Hillarange was bought out by Seaward if that helps. Many of the parts were interchangeable between brands so possibly the plunger and other parts will work from here. No guarantee.http://www.ess-kayyards.com/catalog/homestrand.html

Michael - there should be a hydraulic repair shop in your area, or call a tractor repair shop and tell them your project and needing a O ring. If you have the old o ring take it down to the shop with the stem and the stove. The shop should be knowledgeable about O rings and measure the components, you might have to buy a couple different sizes and thicknesses. There are different types of O rings out there too, so ask for advise. At my local shop the O-rings aren't expensive..25c each.

Also buy or ask for a swipe of O ring lube (don't use Vasoline) to lube the O rings.. it makes a huge difference on setting them.

Remember if you scrape, cut or damage the O ring it won't work properly. Sometimes a brand new O ring won't set, and you have to replace it again.

You can get super O rings like Chemraz or Kalrez brand too..but they are expensive.

Cont.....

Also look at the metal surface the O rings set with, buff out any scratches or seams from the manufacturing process...look with a magnifying glass or reader glasses to make sure the surfaces are good.

On the stem, make sure there isn't a defect that scratches the O-ring when sliding the O-ring on, I've seen that happen too.

I'm guessing the stoves can be made to work correctly if the correct O-rings are used and the stems actually were manufactured within their design specs.

Not sure what you are calling an O ring But if you are referring to what holds the round metal piece that the rubber seal is on at the very bottom of the plunger shaft it is held on with an E-Clip or an E-Clip retainer that clips into the little groove on the shaft. It might have fallen off and could be inside the tank.Or it rotted away.

A waste of time? Fitting that be the first thing I hear, my #1 character trait! I'm at my worst/best, in situations like this, especially when my own excesses are at fault. I over pressurized and refuse to be defeated to a minuscule part. Only time will tell!

Appreciate the sound advice. I thought I would check a propane shop too. A neighbor suggested Vaseline, it made the fit too loose. I may already have the right size and only need O ring lube.

Scott, I've seen those images, mine is different. There was nothing in the piston chamber, once I un-threaded the cap. Thought O ring must have fallen inside the tank. But it appears the opening is too small. Likely fell out the open end, undetected. Anyways, here's my stem, with the replacement O ring. The piston plate at the bottom appears to have it's own O ring? Should I attempt to lube it; if so how? Thanks![https://www.facebook.com/photo.php?fbid=10216532846103225&set=a.10216532845823218.1073741828.1520380419&type=3&theater][/https://www.facebook.com/photo.php?fbid=10216532846943246&set=a.10216532845823218.1073741828.1520380419&type=3&theater]

You can also splice an o-ring. Use to do it all of the time on non-hydraulic ones. Find a longer o-ring that is the right diameter. Cut it so that fits properly and then super glue it together. Carefully smooth the seam down with a razor and you are good to go.

There are some kits on amazon, but as long as you have a good eye and steady hand you won't need them.

Love your perseverance. I know it's not the exact piston, Like I said Parts are hard to find but they all work the same. Sorry, Not a member of Facebook so I can't see the photos.

Opps - I was thinking about a different set-up for the curtain burner. My bad.

Cleaning out the piston chamber, I pried out the base plate and found a tiny C clamp inside. Felt a little foolish, thinking a O ring would have held the stem and plate together. (For those that don't use FB, it looks similar to what Scott posted.)

Anyways, it functions even better than expected. Can't recall feeling a sensation like this, in a while! Of course, it took 10 minutes to boil cold tap water. A single burner butane/propane will be a must, for coffee. Otherwise, don't cook at home, can't imagine it will get much use.

Thanks to everybody for your advice.

I forgot to mention that to lube the tube and rubber HD or any hardware store has small containers of waterproof grease for lubing O rings in the plumbing isle. Stay away from petroleum based grease that might swell the rubber. Even pool stores sell O Ring grease as an alternative.

Yeah Scott, I still need to lube. Plan on using silicone grease.

I see my last post was two of the same. This is her ablaze!

Good for you for taking on this project! Tenacity! Perseverance!

Reusing, rebuilding, maintaining are good for the environment too!
