Optimus 200P pump tube stress cracked?

Ever seen a crack like this? I havn't.

When fettling a Optimus 200P it was impossible to build preassure. The NRV in good working order. Found that the pump tube was cracked.

Only on a Burmos 96 (kerosene stove) pump tube.

Nope. Are you going to repair it? Or perhaps even make a new one?

 

Brass is susceptible to age hardening. Is is possible to get brass tube of the correct diameter to replace it ?

 

I'm going to try soldring it. First i'll drill two holes to stop further crack.

I have from other lantern, but not correct diameter.

 

Yes, I had a Tilley PL-53 pump which had the same problem.

 

In the past I have had sucess finding seamless brass tubing at model engineering suppliers. Good luck !

 

I've never seen a pump tube crack like that before...

 

Hi again!

Tonight I drilled two holes. Used my Dremel tool to clean the crack and finally soldered it. Next step will be to even out the surface of the tube.

It happens. I have had two Tilley pump tubes crack like that. Not always that easy to diagnose either especially with a fixed pump. It's rare but just something to be aware of when any pump doesn't work. ::Neil::

 

Yes, there was no preassure build up at all. It was when I filled water into the tank I noticed it

 

And here it is, running with a mantle for the first time. Had it running Yesterday without mantle.

Takes only 3 stroke to build preassure.

Regards Matti

 

Nice job!

 

Good save Matti - you must be pleased, it is working well.
