Sheridan Model B Sporter

[jirushi]

Hi,

A friend bought this Sheridan Model B Sporter recently from the USA.
I am going to try to make it work again.
The pump cup doesn't seal in the tube. A friend advised to soak in transmission fluid stop leak.
Hopefully that will work.

I would like to "get into" the valve.
Mostly out of curiosity, but probably because it needs new seals.
There's no info on the net on how to do this.
I guess a special tool is needed to unscrew the valve nut?

Here are a few photos. The gun has seen some life, and I think the barrel blocks have been re-soldered. That might be the reasons why all the paint (B's were painted, A's were chemically blackened) is gone.

Cheers, Louis

That's a good challenge to take on, I hope you can getting it shooting again.

Nice Sheridan to have Louis - makes me jealous that you can import from the US freely.

You know who to ask if you want the definitive answer on the valve

Thank you gents.

I shall indeed contact The King of Seals

@Trevor, good tip, I've sent UJ an email.

The pump cup is soaking in "transmission fluid stop leak". If that doesn't help, then I will try to flare it up.
Although I can't unscrew it. It might be Loctited.

The valve is out, with thanks to advice from UJ Backus.

I would like to unscrew it, but it's super duper tight.

The logical thing would be to replace the o-ring and then test if it seals, but it would be interesting to "get inside".

Perhaps it needs some heat, and collets.
