Help required after seal kit replacement

Sat Jul 06, 2019 3:27 pm

Hi all,
Just registered to the forum and require a bit of assistance if possible.
I had my first s410 carbine new approx 15 year ago and just used it for shooting bunnies etc. Just literally use to fill it and shoot it, never cleaned it, serviced it or anything and eventually sold it about 8 years ago. I recently brought a secondhand one because my friend got into HFT. Now it’s been great for about 6 months and then I was finding it was empty everytime I would grab it to go out. So would fill it up and use it and it would be fine while shooting. Would go home with about 100 bar and a couple of days later would check it to find it would be empty. So today I replaced the seals which was quite straight forward however I have 2 questions.
1, on the exploded diagram from air arms there seems to be 2 seals I can’t find in my gun. Number 60 on the diagram. S650A
2, I found a little collar on the bench which I’m unsure of where it came from possibly from silencer area, however nothing obvious and can’t find it on the exploded diagram so abit puzzled.
Apart from that well chuffed with the outcome.
Thanks for any help in advance.

I'm sure the 650 o ring goes on the bolt just in front of the cocking handle.

There was 2 x 650A Orings in the kit but not a 650 so used one for the loading bolt.
At the moment i can't seem to be able to upload a photo of the collar

650a sometimes fitted to the brass barrel seal holder, to remove play in barrel, the other part, did you remove the pot ?

No didn’t remove the pot.
I removed the barrel and the barrier seal carrier. What is the procedure for refitting the barrel seal carrier? Do I need to loctite it to the barrel and loctite the carrier into the action?
I only took the seal carrier out to find the seals that didn’t exist.
Thanks

Loctite seal carrier to barrel, but don't loctite into the breechblock

Spoke to julian yesterday evening and he has suggested the collar looking bit my actually be a ring of old loctite presumably from when i removed the barrel. Thinking about it now i think he might be spot on, maybe because its old it looks like metal. So will have a look a bit later. Thanks for the advice about loctiting the barrel carrier to the barrel this is also what julian suggested.
Thanks for all help
