Tilley butterfly pump knob

- yes I have observed this as well. Best to remove all "variables" from the equation. The old seal may well be very hard/crumbly and difficult to remove but it should be done

 

I do understand it should be best to fix the packing box but, so far I have not succeeded in removing the knob.
Getting loose bolts and or nuts using heat is a well known method, but in this case it may be a bit tricky not to disturb the knob itself.
But the knob has a brass insert, some sort of nut.
I think I will try to warm up the gland nut, hoping the temperature will move to the knob through the axle.
I will be using a very fine hobby gas burner, Campingaz cv 360.

I will be back, regards.

Have you tried pliers with a little packing to minimise damage ? I do not think heat will help as it has already been hot when you lit it.

 

Absolutely, and a piece of leather around the knob but in the end I didn't dare to use more force.
And my experience when working on old cars and having struggled with nuts and bolts, it certainly helps when hot, not been hot.
I think I will buy a suitable locking pliers in order to get maximum grip on the axle.

To be continued, regards,

Ton.

 

YES!

In the end it came off. I used two pliers indeed, but I screwed the smaller one holding the axle in a vise in order to fix it steadily.
And the big plier with a piece of leather made the job.

Thanks very much for all the advice!

Regards,

Ton.

As to its provenance, Rijkswaterstaat is a huge candidate: see picture from a stash in Zeeland - where RWS was and is intensely present.



There were likely more "Guardsman' types than SDR lamps, but many of those X246's were used to the bitter end and vanished, likely for being more practical than the finicky SDR's with irreplacable globes.



The colour itself has been described as Duck Egg Green but also Duck Egg Blue iirc. A colour used earlier by Tilley for some heater(s), again iirc. Some ornithologist among us to break the balance?

 

"Duck egg blue" paint was widely used in WWII aircraft undersides, by many countries. Maybe it was surplus paint from the 50's ?
