    Hello All,

    I just came across this site last night doing a search for a rebuild kit. I must say it is a very interesting site with lots of cool stuff.
    Anyway, I am the original owner of a Phoebus 725 that I had purchased around 1979 or so. It has been with me on more hikes and climbs than I can remember and is still in use. While it still functions fine, I thought I would treat it to a good cleaning and rebuild so I could get another, umm, 35 years out of it, lol.
    Before I take it apart does anyone know who or where I can get a full rebuild kit? I have come across a service kit on Ebay that shows some parts that are for a model that has a fuel pump which mine does not have and it looks like it does not contain all the parts to do a complete rebuild.

    Thank you in advance. Phoebus 725.jpg

    Hi Seatracks and welcome!

    I see a rebuild kit of the 625 in the Fettlebox (upper right side of the home page).
    https://fettlebox.co.uk/phoebus-625-washer-kit.html

    If that doesn't work, you can always make replacement seals for most classic stoves with a small sheet of Viton (Check eBay) and a simple hand punch set.

    Good luck! Jerry

    Metropolitantrout,

    Thanks for the heads up. I did not know the parts were interchangeable with the 625. Would you happen to know the thickness of the Viton needed?

    Not sure they are compatible "if that doesn't work". Just pointing out that kits for some stoves are available here and they are generally not commercially available. Perhaps someone else will chime in or you might have to dig thru some of the threads to be sure.

    I have a small sheet of 2mm which works for most seals and another of 3+mm which works for most pips.

    Thanks again. I sent an e-mail to Fettlebox to ask what they have available. I have spent the last few hours pouring over this site for anything additional information. Next step is to find a parts diagram.

    Yeah @ fettlebox will better know if the parts fit. I'm sure he'll answer in the morning.

    Quickie photo of the spares kit in mine. Includes spare jet (marked 'F' - as is the one installed in the stove) and needle, manual pricker, SRV pip, fuel lid washer. and another washer (lower) whose purpose I don't know. If necessary, I can get measurements for the washers and pip -- hopefully tomorrow.

    This may not be an original spares kit (note the pricker marked "Camping-Gaz") but it was in the stove when I purchased it.

    OK, sorry for the delay. I can't seem to locate my micrometer, so these are eyeballed using a ruler.

    Fuel lid washer (the upper one in the photo) OD: 19 to 19.5mm
    (washer is slightly out-of-round) ID: 13mm
    Thickness: 3mm

    Washer of unknown purpose (lower in photo) OD: 17mm
    ID: 9mm
    Thickness: 2mm

    Pip (slightly out-of-round*) Diameter: 6mm
    Thickness: 3mm

    *The pip is not so much out-of-round as it is slightly uneven (dished sides) from being punched out.

    Best I can do for now. I hope this is helpful.

    These spares are likely the same age as the parts currently installed in the stove. They are still pliable enough to be functional, but I should probably also order a set if you're (Ross) going to make up a set.
    I would be happy to test these in my 725 if Seatracks wants to wait for confirmation they are the right size.

    I remeasured with the micrometer, and I'll stick with the numbers I reported earlier.

    Thank you Arch.
    I'm waiting for Ross to get back to me so I can place an order for a few sets.
    My wife is telling me to just get a new stove but I don't want to retire this one. It is so reliable and has never in 30+ years given me a problem at high altitude, sub zero cold or high winds, it just keeps on going.

    Phoebus stoves are little workhorses. It's well worth getting this one going. The 725 is built like a tank.

    The 625 has been used at high elevations in the Himalaya.

    If you can both @ArchMc @Seatracks PM me your addresses please I'll send a sample set of seals out.

    Ross,

    I received your gaskets today. I will rebuild this unit over the weekend.
    Thank you very much for making them and sending them across the pond.

    Regards,
    John

    Good luck. They were the nearest I could do from the given dimensions but hopefully they won't need much of a trim if any.

    Hi Ross,
    The gaskets.arrived while I was out of town. I just got back. I'll give them a shot tomorrow or the next day, and let you know how they work. Thanks very much!

    I installed the new seals today. First task is to note the position of the SRV retainer, so it can be tightened to the same place. With the wings horizontal, I see the screw as being at the 10:25 clock position. (It turns out this doesn't really matter -- at least for this stove -- as the screw bottoms at that point.)

    Here's an exploded view of the fuel cap assembly, with the original seals on top (which are still pliable) and the new Fettlebox seals below. (I never could find a place for the extra "mystery seal", and I figure it's extraneous -- just a random part included with the stove when I bought it.)
    exploded view.JPG

    So let's test it. I double primed it, as it's a really beefy stove -- lots of metal to heat up:
    Priming.JPG

    Once it heated up, turning the valve led instantly to the left photo, and within a minute to the right:
    Instant on.JPG Settled down.JPG

    It goes pretty much from 'off' to 'full on' to 'off' again at full counter-clockwise as the cleaning needle blocks the jet. With some delicate adjustment very close to the clockwise 'off' position, it's possible to get a simmer. I recommend keeping a sparker handy in case you go too far.

    I would rate the new seals as a complete success. Great job, Ross!

    I have a few more stove porn pics that I'll add to the Flameshots post.
