la bala Posted May 19, 2013 Report Share Posted May 19, 2013 hi guys, my son has a air arms 410, yesterday when pumping it up, it developed a leak at the pressure gauge. He unscrewed the gauge from what to me looked like a small valve block and renewed the o ring. After screwing the gauge back, he still has a leak and the small block he screwed it into is moving. any ideas please, a link to a diagram would be good. thanks in advance.

NIGHT SEARCHER Posted May 19, 2013 Report Share Posted May 19, 2013 Have a look at www.gunspares.co.uk There`s an exploded view of the s410 hope it helps. Or try Air Arms owners for forum. I have an Hatsan AT44 and the gauge failed inside and leaked. I got a new gauge of www.best-fittings.co.uk That sorted it no problem. Good luck.

la bala Posted May 19, 2013 Author Report Share Posted May 19, 2013 i have had some good info off night searcher, but need more, is there any air arms s410 owners online who have stripped their rifles down for repair. i need info on part number C1104S which is showing a screw on the parts list, but on my lads rifle the head of the screw is milled off. I am assuming this is to make it tamper proof, is the whole rifle going to be like this. Quote Link to comment Share on other sites More sharing options...

jackinbox99 Posted May 20, 2013 Report Share Posted May 20, 2013 Ive stripped my s410 down many times as ive tinkered with it over the years. The c1104s bolt you mention on mine is just a normal hex bolt. There are 2 very small rubber seals - one each side of the block as you can see in the diagram. Be careful not to loose them or over tighten. My money is on this is where the leak in, esp as you said the block was moving. Im not sure if this bolt was replaced as part of the anti tamper stuff - i know the power adjuster was changed and one of the bolts holding the action together on the top is dome headed on the anti tamper ones. Mines a pre-anti tamper model. Quote Link to comment Share on other sites More sharing options...
