Stove went south again

#1

Post by 425E »

my m1950 stove is broke again. I need to know how the eccentric stem tab (inside valve body) that controls the outside stove knob position when turned is oriented. Is the tab installed straight up at 90 degrees or to the left or right at 180 of left and right of 0 degrees, if you can help it would be very much appreciated. I do not have any way at present time to upload photos.

There is a FAQ section in the forum that has methods of posting pictures, which will be helpful in understanding your situation.

The tab inside the valve body that controls the knob on the outside that determines whether is on light or on when turned to the left or off when knob is turned to the right. what I'm asking where is tab turned to when reinstalled in the stove up down left or right

Unless I'm not understanding your issue, look at the eccentric itself. The cutout in the lower section of the eccentric needs to face the valve. You may have to fiddle a bit to ensure the part of the valve that engages the eccentric is lined up properly or it will be tight before it even engages and therefore won't work.

jiml what i was asking for help with is the eccentric stem that the knob itself fits on. that has the tab on the stem when installed is inside the stove valve body that is screwed inside the tank. I have make sure the eccentric block that has the cutout for the tab or slot is turned toward the knob. i just cannot get the knob set so that it turns full off or on I know its got to have something to do with tab on the eccentric stem but I tried everything I know of turning the tab to the left to the right or up the seems not freeze up either way. Its just stops at light position. regardless of how the tab is installed in the eccentric block. hope this helps someone understand my dilemma.

I just looked at one and the flat spot on the stem is facing the valve knob. Sounds like the little nipple on the valve stem isn't properly engaging the eccentric. See the pic below. The nipple on the valve, A, needs to engage the slot on the eccentric, B As Steve(?) stated in another thread, which I now cannot find, that eccentric is spring loaded so you will need to push down on it just a tad so you can screw the valve in and get the parts aligned. If you don't, the eccentric may move a little, giving the impression that it's engaged, but it won't be. I just demonstrated this for myself.

Ignore the fact that the valve on this is broken. :(

Much appreciated JimL. That was exactly what i was talking about. The key words were to press down because of the spring loaded eccentric valve. The part about pressing down on the valve spring just did not occur to me because i guess i just got upset cause i couldn't fix the blipping thing and get it to work. Very Very much appreciate the help. Hope I can return the favor sometime.

Brad c much appreciate your offer to help. Had not just Jim L clarified things for me and set me on the right track. I would have asked you for help. However I have every thing assembled correctly now and the stove has been completely reassembled. I have changed the cap gasket and the pip or dot in the NRV valve and now pressure testing the stove. Thanks again Brad C and Jim L

If it appears you have a pressure leak with the new pip, make certain the pip is sitting in the fuel. I just realized this last week with an M-1942. It wouldn't hold pressure for long with just air in the fount, but works perfectly as long as the pip is in fuel. Regardless of whether it hold back air, holding back fuel is what's important.

I don't want to fire the stove up inside I may get beat up. But when I get the stove outside to do a burn test. It is very windy here today. May try the fire up Monday. I'll let everyone know know how the burn test goes.

This is to Jim. I could not get the stove to hold pressure after what you said about putting fuel in the tank the stove held pressure without leaking air or fuel into the pump tube for over two hours. Your knowledge and expertise did the job. You have been a great help. Which is much appreciated and the other post as well.

Thank you, glad to help. We all learn from each other here, which is what makes this hobby so awesome.

You may want to add your first name in your profile or a signature so we can address you by that. I suspect your friends and family don't call you 425E. :)
