I dismantled my primus 980 today... looks like i need some spare parts... Yes those parts are bent... is these change to get spare parts or should i try to repair these... that valve is also stuck How i am supposed to get pump valve away from end on its pipe? I think is is jammed. Edit. I just noticed how these are similar with small airbrush
There's nothing there that can't be straightened. First remove the jet and ceramic mantle holder from the vapouriser tube and the remains of the cleaning needle from the cleaning rod then anneal (soften) the brass by heating to a dull red and then quench in water. Then straighten using whatever tools fit. I have a screwdriver that fits perfectly in the lower tube of the vapouriser and then use an adjustable spanner to hold the top part. These vapourisers are quite strong so a lot of force is required but do it gently as you don't want to bend it too far. As for the pump valve, you need a special tool to get the valve out. There has been at least one thread about this tool but I can't find it right now of course.
As Nils says, it has been written many times about the pump valve, generally often abbreviated NRV for non return valve, so there's plenty of information in the forum already. here's just one quick example where you also can see how the NRV look like once it has been removed from the pump tube (and also one that's been taken apart to show you the rubber/cork pip that seals). So as you see there, all you need to do is to get a good piece of steel that fit snugly inside the tube, and make a 5mm wide slot straight through the flat end of it. I think the pictures in the link tell you all. Mind you, these valves can sit extremely hard, so it's best that you have a good tool with a snug fit on the valve head, otherwise the brittle brass valve will be deformed in no time, probably meaning that you'll have to unsolder the entire pump tube to get it out...
Thank you, those pictures help a lot. Slowly learning new things about these lamps... Yesterday i heard that old mantles are radioactive I am curious to know what is price level of these old pressure lamps? (not going to sell... just want to know )
It varies alot, Pertsa. If I find it at a local flea market or such, it can cost perhaps less than 100 kronor (around 10 Euros). If sold at eBay it can rush up to silly prices of more than ten times that. So there's one possible span.
When i heat brass does it really turn little red I managed to make other parts work, ultrasonic cleaner did its job, but glass is broken and that "cleaning needle" (if I use right term)is bent.
There is some stains inside of fueltank. What you think? Could i damage it if I link tank with drill and put something hard to inside to remove dirt from sides of tank. Edit. Hopefully someone understand what i am meaning
I would fil the tank with hot soapy water and let it sit until the water cools and then pour out the water. If that does not clean it, then I would fill the tank with vinegar and leave it for 10 minutes. Then pour out the vinegar and check the tank again, if the dirt is gone then wash out the tank with fresh water and let the tank dry. If some of the dirt is still there, then repeat the vinegar process as often as is required, Jeff.
If it is actually dirt in the tank, you can try putting some kerosene in the tank with a handful of nuts (not the type you eat ) and give it a good shake. Make sure you count the nuts so you get them all out.
Just make sure you only use magnetic nuts, i.e. not stainless or brass. That way it's easy to get those last stubborn ones out with a small magneto.
It is hard to describe what it is with my bad english :/ I looks like old paint which is falling off. And has heavy smell of lamp oil. But i try these... maybe get most of it removed.
It sounds like residue from old fuel. You can use ball bearing or round lead fishing sinkers, too. If it is really caked on and you still can't get it clean, the makers of POR 15 have a product called "Marine Clean" which is a very powerful water-based cleaner designed to clean fuel tanks. I've had to resort to it once. Use it sparingly (and recycle it by filtering it after use until its useless and it will last a long time). With the left over Marine Clean I've got, I use it to help clear the carbon in vaporisers.
