Greetings, All, Well, I just tried to buy one of those Coleman powermax fuel adapters #9705-725, and so far, no luck in finding even one!! I think highly of these stoves, and the single version, too, and would actually buy two of the adapters, if I could source them. On second thought, I'd buy one, and if it worked as I think it will, then spring for the second one. I'll keep looking..... Thanks, and God Bless! Every Good Wish, Doc
Hi John, This was a post about the Power Max Xpedition stove. The gent made his own adapter. It's interesting what people will make when the need is there. Very ingenious of him. Looks a bit rough but it works. Thought you might be interested. What is below is a copy from the post I read, but you can click on the link below and read the whole post, after all it is very interesting. I'm sure you are or will be coming up with something very similar so I'm look forward to seeing it. Cheers, Norman http://www.bwca.com/index.cfm?fuseaction=forum.thread&threadId=717864&forumID=15&confID=1 Here is a picture of the bare valve. I broke the coupling off when heated it up with a propane torch and tried to remove it. It exposes a 1/4 inch circular recessed area. I tried soldering the brass coupling in the lower part of the photo, but the joint was not strong enough. Here is the same valve with a 1/8 nipple brazed onto it. I actually used a short piece of 1/4 copper line sandwiched between the valve and the nipple part. I also sawed off some of the thread on the nipple part as they were not needed. Here is a preliminary test I did this morning, and it seemed to work well. I'm still waiting for the 7-9mm ear clamps to permanently attach the main fuel line and I still have to shrink the heat shrink tubing. I have not tested white gas with it yet, maybe this weekend.
If you are using the fuel line of the t800 and putting that onto the fitting the same size as rhe t800 uses, the 7-9 mm clamps are not quite tight enough.
Hi, Teck_guy, I hope you can post larger photos of your adapter, as I really can't see much from the tiny ones you posted. After reading about the horror stories of many who have bought the now discontinued Coleman adapter for these stoves, I'm less inclined to purchase one for myself, and would rather make something that would work better, or have someone make it for me, if a good machinist were to take on this task. The stoves are far too nice to let languish on a shelf, unused, once the cartridges are all empty. Thanks, very much, for the link on the BWCAW site. I look forward to seeing how all this plays out, and feel confident that someone, or some company, will eventually produce and sell a safe and reliable adapter for these fine stoves!! Shame on Coleman for what they have become, and for the shoddy adapter they half-heartedly made available for a while..... Though, it's probably better that it is gone, rather than take a chance on it leaking, as so many obviously did. Good luck, and God Bless! Every Good Wish, Doc
A month ago I bought one of the Coleman adapters from Coleman, however it looks like they are out again. http://www.coleman.com/product/9705-725#.VGfIaxZS5zY Try Google searching for one; and If I run across an extra one Ill let you know.
Ok... there is a company that makes an adapter called a "P-Type Refill adapter for Coleman Powermax Fuel Gas cylinder" they are in Japan, I don't remember their Company name, (I think they are out Korea or Japan...) they do sell sometimes on Ebay. Last one I bought was $57.00 USD Hope this helps.
I have several of the Powermax stoves and lanterns. In general they work well and do work better than a standard butane/propane gas canister. However my experience is that below 20F the canisters do sometimes run out of steam when they get about 1/3 full(shake the can guess). they perk right up again if heated. Not what I expected of these canisters. It has happened to me on a couple occasions. However, due to some experimenting this year, I cut open a canister and the gas tube though attached fell off with my normal ape like handling of the assembly as I examined it. Perhaps some of the canisters have this problem while in the field and thus when the appliance is running, it is actually not always running with the full liquid feed. I am just guessing based upon my examination of that one empty canister. BTW, I have seen 3 different designs for the gas tube and weight in the Powermax canisters I have examined over the years. The one discovered failure(tube fell off) was the I assume more recent design that just has a plastic tube with a metal tube extension as a weight. The reason I was examining the canister is that I am having more frequent leakage of the canisters, even after a short use(last 2 CASGs). I discovered that some O ring from the canister itself had dislodged and then caused the valve to be stuck. This has happened to perhaps 6 canisters over the past few years, essentially every one I used in that time frame. To be fair the canisters were stored in an uninsulated garage that got very hot in the summer, not good for rubber or plastics. This is the thread regarding the leakage issue... https://classiccampstoves.com/posts/282871 So I would no longer depend on the Powermax appliances as a reliable frequent use item. Just for fun now.
I was inspired this afternoon, and dug through my kits, Since Coleman has discontinued the old adapter I think with minor fettering one can adapt my canister adapter from my Firestorm 9770 stove to work with the Xponent stove. Looking at the Coleman page - http://www.coleman.com/Parts/Part/9770-5181/adapter-valve-assembly-with-caps Coleman says they still sell this adapter and for $27.00 USD. Also with the use of another Hose assembly with cap 9770-5151 (Coleman page..) http://www.coleman.com/Parts/Part/9770-5151/hose-assy-wcap This hose could be adapted to fit.
That looks familiar. I am on the forum that posted it. Used canister valves and hoses from Asian donor stoves. Modified the valve body to accept different hoses. Both single and double burner stoves work great, canisters upright or inverted. KM
The photos posted by "teckguy_58", are from a forum posting that looks familiar. I have done similar modifications to Coleman PowerMax stoves. Used a spare parts canister stove as donor for valve and hose. Modified Coleman Exponent runs great with canister fuel, canister can be inverted to feed liquid fuel. Similarly modified single burner. KM PS: I think I get it now. km
I am still not convinced that the "-701" needs to be in the title. There is considerable evidence that points to differing numbers after the "9730". The 3 models of stove in this series are the 9710, 9720, & 9730. If searching for the 9730-725 these Coleman pages shows up: Link Link Excerpt from the page shows Features or Parts & Manuals of the stove. If searching for the 9730-701 these Coleman pages shows up: Link Link Excerpt from the page. (Note that here it says the stove is no longer available) Another page, a parts list for the 9730-701, has a link to a manual. The document is named simply 9730.pdf....... Link A different page, a parts list for the 9730-725, does NOT have a link to the manual. But, other than that it seems the page is identical to the one above. Here are 2 photos of my box containing my Xpedition stove. In the upper image, you can see the 9730-900 in the lower right corner of the stick-on label. I cannot find anything about that dash number when searching the internet. But, it adds to my questioning the validity of the need for the "-701" in the title. The bottom photo does show the 9730-701 on the cardboard, lower right corner, of the back of the same box. Conclusion: At the expense of seeming nit-picky, I only suggest that the title be changed again to remove the "-701" as it may or may not be correct for the model of the 2 burner Coleman Powermax Xpedition stove. I hope that we can get more information to clarify this minor detail. Ken in NC
In this thread ... Link ... a link is made to a manual (same as in my post above, and the title of the manual is said to be 9730-701, but if you look at the document, it is simply 9730. Coleman named the same document 9730.pdf. Ken in NC
WOW! Great explnation on the Power Max! Thank you! @presscall Great photo exposition of the stove! I am humbled every time I come onto this site. And I'm damn sick of it! (I used to be smart!)
