Marksman1997 Posted October 12, 2015 Report Share Posted October 12, 2015 As mentioned in title i have a bit of a problem and need somebody that knows a bit about gun repairs or something. A old man brought his old springer air rifle out to me as he said it would not put the bullet out but went bang... Opened it up and a pellet fell out shortly followed by another. Then looked down the barrel into the sky (from the pellet insert area not the muzzle!) and couldn't see any glimpse of daylight so got out the rods and pushed out another pellet. Then looked again and seen daylight but had heavy leading were the bullet was stuck used hoppe's 9 to remove leading and fouling and pulled rag through it repetitively. Looked down and it was squeaky clean. loaded one of my pellets incase his was faulty or too big. Fired at a can and no bullet. Opened up gun and out drops pellet. Any idea people...??

FalconFN Posted October 12, 2015 Report Share Posted October 12, 2015 My first guess would be piston seal, either completely disintegrated or has become detached from the piston, but there is an outside chance it could be something more serious like a broken piston head. What rifle is it? Quote Link to comment Share on other sites More sharing options...
Dave-G Posted October 12, 2015 Report Share Posted October 12, 2015 I'd hazard a guess that the washer is in fact not a washer any more. Do you feel any 'recoil'? You PM'd me a few days ago - are you sorted now? Quote Link to comment Share on other sites More sharing options...

Zenduri Posted October 12, 2015 Report Share Posted October 12, 2015 No compression so most likely a knackered piston seal as others have said. Quote Link to comment Share on other sites More sharing options...

You PM'd me a few days ago - are you sorted now? Yea Dave got sorted ok. Now that you mention it the gun near bounced out of my hands. More like a big vibration or shake. I looked at gun make and im not at home to check but its a German make but not weihrauch kinda similar though. Quote Link to comment Share on other sites More sharing options...
Marksman1997 Posted October 13, 2015 Author Report Share Posted October 13, 2015 Also how much does a piston seal cost to get fixed? Is it handy to do? What exactly does the piston seal do? Sorry for all the questions but i need to tell the old man whats wrong. Quote Link to comment Share on other sites More sharing options...
Dekers Posted October 13, 2015 Report Share Posted October 13, 2015 Also how much does a piston seal cost to get fixed? Is it handy to do? What exactly does the piston seal do? Sorry for all the questions but i need to tell the old man whats wrong. If you have a good old fashioned bicycle pump, unscrew the end and you will find almost exactly what the piston/seal is/does!

Sorry for all the questions but i need to tell the old man whats wrong. Well, I put a new leather one into my old BSA when I was aged 12. It should not require great mechanical skills Quote Link to comment Share on other sites More sharing options...
saddler Posted October 13, 2015 Report Share Posted October 13, 2015 No piston seal means the piston will be slamming into the end of the cylinder. ..which explains the noise. Post the maker info. Chances are the seals are still available, or can be fabricated (leather washer) Quote Link to comment Share on other sites More sharing options...

7daysinaweek Posted October 13, 2015 Report Share Posted October 13, 2015 yes i wholly agree piston head seal. used to regularly renew them on loads of springers when i was younger,not a difficult job just think it through so no nasty springy surprises ensue resulting in injury. check out youtube for vids Quote Link to comment Share on other sites More sharing options...

Marksman1997 Posted October 16, 2015 Author Report Share Posted October 16, 2015 (edited) Name on it looks to be Feinwerkbau for those interested. Is it even worth fixing as it is pretty old. Edited October 16, 2015 by Marksman1997 Quote Link to comment Share on other sites More sharing options...

chris1961 Posted October 16, 2015 Report Share Posted October 16, 2015 Its probably a leather cup washer TRY putting a few drops of oil down the barrel clear of pellets and stand it up for a couple of days the oil soaks into washer and swells it I had an old hw35 that was the same it was the washer that had dried up soaked it in oil for a couple of days was perfect after that the reason you put oil down barrel is the washer expands as it soaks up the oil can be a sod to get back in chamber I found best way just put oil down barrel and stand gun up stock down and leave it a couple of days then turn gun round on a cloth to allow surplus oil to drain out it will smoke for a few shots but it will clear leather cup washers need oiling regular to keep them in good condition Quote Link to comment Share on other sites More sharing options...

Good to know thanks! Its probably a leather cup washer TRY putting a few drops of oil down the barrel clear of pellets and stand it up for a couple of days the oil soaks into washer and swells it I had an old hw35 that was the same it was the washer that had dried up soaked it in oil for a couple of days was perfect after that the reason you put oil down barrel is the washer expands as it soaks up the oil can be a sod to get back in chamber I found best way just put oil down barrel and stand gun up stock down and leave it a couple of days then turn gun round on a cloth to allow surplus oil to drain out it will smoke for a few shots but it will clear leather cup washers need oiling regular to keep them in good condition I will try this when i get home as it could be a easy fix.

Doyourself a lot of hassle OP and just take it apart and properly service it. Quote Link to comment Share on other sites More sharing options...
