I’m having a bit of a problem, can someone tell me if the clamp nut on a Hendon pump for a 1950s Tilley R1 radiator is supposed to come off. I’ve removed one but had to tighten the vice on the bottom end of the pump so tight I appear to have broken the solder around the bottom and now the pump fills with paraffin. I have a spare pump that needs a washer but don’t want to damage that one. Thanks in advance Malcolm
I'm assuming you are talking about this one. I also assume the pump is female. (they did come in male or female but the R1 male is rare). If this is the case the clamp nut is not meant to come off.
Thanks Anthony, yes that is the one I mean & it is female. When I finally got it apart I thought I looked it be soldered. So presumably you have to take the washer out down the pump tube then
The female pumps don't have a washer. Pumps for lamps with tanks which have a female fitting do. Because the tank is the major part of the lamp, the male / female thing refers to the fitting on the tank. Here is an image of a male pump intended for the female tank fitting.
Hi @malcolm race .. What is the vice that you mention here? Could you show us a photo to clarify at all?? Ah! .... you mean you put the pump in the vice? Sorry.. I see it all too late... i've got me coat on..... (door slams shut...)
Thanks Henry, mine is the older type, ie external thread on tank ( male ) internal ( female ) on the clamp ring
Ok thanks everyone, I’ve decided Ive broken it, so order an other from base camp. Just goes to prove even after all these years you can still learn something new. Cheers
@malcolm race Sorry if this is confusing. I was thinking of the shaped brass washer as shown in the image above. Of course there is a rubber washer (seal). I've sent you a PM.
