Does anyone out there have any experience with taking apart the 508 gens? More specifically getting the eccentric block out of it or is it even replaceable? Or do I need to just replace the whole gen? I know they're like $39 for the gen on OCP and I only paid $35 for the stove.

Here is some background story...

I got this stove not too long ago and used it twice and really loved how easy it is to turn the stove from a full roar to a simmer with ease. I took it along with me on my hiking trip to Gatlinburg this weekend and as soon as I got there Thursday evening I wanted to make a pot of coffee. I pumped the stove up but it just would not light. I checked and made sure there was plenty of pressure and cracked the nut at the top of the shutoff valve and fuel was flowing just fine there but it was not making its way across the gen to the burner. I moved the cleaning lever from HI to Clean a few times and finally the lever hit a hard spot and made a popping sound. I took the stove apart as best I could with limited tools that I took with me down there and couldn't see what was going on. I took it apart better tonight after I got off of work and found that the pricker rod somehow got stuck in the orifice and broke off of the eccentric block causing the lack of fuel flow. I had to use a pick to knock the pricker out of the orifice. I took a tiny pair of needle nose and tried to pull the eccentric out of its bore but it didn't want to let loose. 

So here are some pictures of what I found and any info you might have for me would be greatly appreciated.

I'm glad you got some use out of the stove, but that absolutely sucks. That stove looked like it had been lit about once before. I wonder what happened?

Eager to find out if this can be fixed.

Is the 508 a generator that has been discontinued?

Yes, the 508/400 gen is discontinued.

If you reassemble the generator without the pricker, does the stove still generally work and is controllable? A new generator might be worthwhile to get running again, but that might just be from a collectors point of view. A bristle from a wire brush might be used for manually cleaning the pricker orifice when needed.

zoomkat - I thought about trying it to see if it will still work ok without the pricker which I'm sure it will but I have a feeling it will be hard to throttle down with the on/off valve. I will give it a try here in a few minutes and post the results.

Its all good Timm, I will get it fixed I'll just have to do some checking to see how far I will have to go to fix it. No worries.

Now, on with the fire... [Flamie]

If the eccentric assembly is like the ones in the lanterns, you will probably need to loosen the  packing nut on the pricker rod and try to pull out the pricker rod and packing assembly to free the eccentric block. Heating the packing area may help loosen it for pulling out.

Well I took the stove back outside to give it a try and see if it will work without the pricker and it does just fine. But... It will not throttle down at all. No matter how easily you turn the ON/OFF valve down I cannot get the flame to lower what so ever. It must have a shrader valve in the f/a tube that positively shuts the fuel flow off so its either on or off nothing more.

Zoomkat - I will have to try getting that packing nut off. I did try to get it out, I got it loose enough to spin it free by hand but I couldn't pull that darn handle out of there for the life of me even with a pliers. I will try again another day heating that packing area and pulling it out again. I may even try to make a new pricker or straighten out the one I got and somehow attach it again.

If anyone has an extra gen for a 508 or even a whole bad stove with a good gen PM me I would like to get this one running again. I like it too much just to make it a shelf queen.

Note that the cleaning lever is probably going to have an eccentric crook on the end that operates the eccentric block. This will probably require the packing assembly to come out as one piece. Below is a recent long discussion of a cleaning assembly. It is a different lantern, but the design of the cleaning leaver and eccentric block is somewhat similar to other lanterns.

I will give that a try sometime and see what I can do with it but for now it will be going on the to-do shelf for another day. I have a couple other projects in front of it that need to be done before the holidays. Thanks for the info hopefully I can figure something out with this.

Good luck on the stove. My 508 would not simmer at all, no matter what I tried. Shelved it 😕

Hello Zac. Is there a difference in the generators between the 508 and 508a? Mike has the gens for the 508a-400 stoves for $12.00. If they are the same, that would be your best bet. It wouldn't even be worth messing with the broken one.

Hey Rob I see the one that you are looking at and I don't believe that one would work since mine has the dual valves. The model I have has one valve is on the air stem and the other valve is on the generator itself.

The 508A generator can not be used on the 508. The fuel valve on the 508 is on/off only. The 508A fuel valve has the E block in it so the fuel flow can be slowed down for simmer. It is not at the end of the generator like on the 508.

Zac,

I have a few extra 508 generators. PM on the way.

I appear to be a few years late of fixing my 508. Anyone know where a generator or two are?

Motorcycle Dan, I think you mentioned something about swapping out a couple of parts a while back in a Technical Assistance post. I'm hoping you can clarify this question so it may help James and some of us down the road to keep these little one burners going strong. That being said
is it possible to remove the original fuel valve assembly and generator from a 508 and replace it with the fuel valve assembly, part# 400-5551 and generator, part# 400B2891, from a 400B? 
TIA

Joe,

I have never done the conversion. But, I do not see why it would not work. The valve looks the same on the outside, but the inside contains a E Block for the cleaning wire to hook up to on the 508A models. Coleman used the same fuel valve starting in the 400B all the way up to the 442's. The only possible issue that may come up is the length of the fuel pickup. Looking at the fuel valve part number for a 533 stove, it is showing a 508 number. The fuel tank on a 508 is shorter than the one on a 400/442 stove. So, you should be able to use the one out of the 508 stove on the 400 fuel valve. 

I want to say I saw a post a few years ago where someone did this conversion and it worked fine. That is why I mentioned it.

Thanks Dan. That is some good info. Hopefully it won't be needed and the 508 keeps chugging along but I'll copy the info and store it with the stove for future reference just in case. You answer is much appreciated.
