Crosman 140

[nath92]

Hi guys I've just come across one of these in a sorry state , I'm looking forward to doing a full restoration on it but I need a couple of bits , mainly the rear sight which I believes slides over the barrel , also seals as she lets a little wind out , secondly I wonder could anyone tell me a value on one of these in both worn condition and restored to as new standard ? Your time is greatly appreciated
Many thanks nath

Hi Nath

Most of the seals for the valve are imperial O rings with the exception of the inlet valve and the exhaust valve.

The inlet valve is the same plastic one as is used in the current Crosman 1322/1377, but I just put a cross cut in the rear of the valve so that I can lap it in with a screwdriver using TCut, G3 etc.

The brass exhaust valve cup has an imperial quad seal inside it, rather than source one of these I simply use a metric O ring --- they're a bugger to fit.

For transfer port seals I use two O rings either side of the steel port.

I think that the pump head seal is available from the US but I convert them to use an O ring as well.


The rearsight is just formed out of a bent piece of steel with no windage adjustment so should be easy enough to reproduce.
You could alternativly fit a scope using the Crosman pistol scope mounts, though you may find it best to use a pistol scope with these.




All the best Mick

No problem, Nath.

I forgot to say --- you could use a custom flat topped O ring piston designed for a 1322/1377 if you extend it, some lend themselves better than others to this.



All the best Mick

I’ve got a 140 here if you need any specific pictures or parts sizes. Just let me know.

Might be of help, especially if interested in ordering parts from the US.
