Just joined and my first post. I purchased an Optimus 45 but know little about this stove. The stove came with an incomplete burner that has a fuel valve but is missing the silent burner parts for the top. I purchased a roarer burner from eBay and was able to get the stove to work but the flame was weak. It would not stay lit outside. 1. What type of fuel should I use? Alcohol or Kerosene 2. I need some parts to make the stove complete. Legs for one. Where can I find parts for this stove? Wendell
Uses kero, pot supports on the bay or Basecamp in the UK. Check for leaks, enough pressure, prick jet? Duane Riser looks too tall.
Thanks for your information. Bought pot supports on eBay but, they are too large around to fit in the holes on the fount. Same hikerduane as on CCF? Want the pieces to make the silent burner work. eBay also? I will have to check out the riser height also. Thanks for your response.
Hikerduane is right. First prick the jet with a proper sized pricker, available here at the Fettlebox. In a pinch I have made pot supports from pegboard parts available at Home Depot. There are not many parts to this type of stove. Many require replacing the pip in the non return valve at the bottom of the pump. The pump leather should be checked. The fuel cap gasket is a common cause of pressure leakage. The two caps for the silent burner may be available here as well, if not, check Basecamp. Not every cap works well so unless some other 45 owners can chime in and tell you exactly what to get, it can be a bit of trial and error. I use the expensive but very clear K-1 kerosene available at Home Depot. It burns clean. I have also gotten many parts from Tilley Lamps and Stoves in the UK.
Hi @Wendell . The riser on your stove looks as it might be longer than on a standard Op.45. It is possible that your stove was used on a Sea Swing gimballed support, as used on sail boats. Stoves used for a Sea Swing require a longer riser tube. https://classiccampstoves.com/threads/optimus-45a-in-bremer-sea-swing.15673/ If you have the longer riser tube you will also need longer, non-standard legs to support a pan holder. You can make a set yourself and we can give you instructions. Please can you measure the riser tube from the tank to the base of the spirit cup? Best Regards, Kerophile.
Hi @Wendell , according tho this thread the standard Op.45 riser tube is approx 30 mm high: https://classiccampstoves.com/threads/riser-tube-and-burner-for-optimus-45.25066/#post-255443 Best Regards, Kerophile.
Given the long riser, the regulated silent burner, and the lack of potstands, I second the guess that the stove came out of a Bremer Sea-Swing. Quick check: at the base of the riser, right at the tank, is the riser itself threaded for a short distance? If so, this was for the (very thin) nut that secured the riser to the Sea-Swing's mounting flange. These specialized risers are, in my experience, rarer than hen's teeth. They're pretty much the only way to make an Op45 work (safely) with the Bremer Sea-Swing unit. If you're not going to find a Sea-Swing and mount the stove in it, you'll probably want to get a new, standard riser, just to lower the CG. It'll also make it easier to find new potstands if you don't want to bother making them yourself (which is, as Kerophile offers, something you can learn here; that's what I did). Alex
Your stove definitely has a kerosene burner and probably came out of a Sea Swing. Here's a photo of an alcohol burner in a Sea Swing which shows the threaded riser @Pitsligo is talking about. Ben
I use K-1 clear kerosene from Home Depot or Lowe's. The stove appears to hold pressure well. I took out the check valve because the stove would not pump initially. Freed up the check valve but I need to pull it once again and do a complete cleaning and inspection. Modified a Coleman pump leather to fit and that seems to be working well. I do not have a picker so I fashioned one from a Coleman picker rod. Will need to do this again with the correct picker. Took some photographs with a ruler next to the piece being measured. The overall stove height seems to be correct. 200mm.
My riser tube measures over 50mms so it looks like it's for the boat version of the stove. Oops, still getting used to posting.
Hi Wendell. You appear to have the non-standard, longer riser tube fitted to your stove. From your photos the riser appears to be nearer 55mm height, compared with the standard riser at 30mm. The overall height of an Optimus 45 is given in the catalogue at 8.5 in, or 216mm. This includes the extra height of the pan legs above the top of the burner (there should be approx 22 mm flame space between the top of the roarer burner and the top of the legs Your stove would have a total height of 220 + 22mm =242mm if appropriate legs were in place. Best Regards, Kerophile.
This seller is the former A and H Packstoves in California and well worth a look for needed parts: http://www.ebay.com/usr/bella10202?_trksid=p2047675.l2559
Grateful for all your information. To polish or leave the patina? I'm inclined to leave the patina. Your thoughts are welcome.
