I was told recently that our old airgun was only firing at about half it's strength/power because the spring was done. Person then gave me name of company from which to get a new spring, which he reckoned would cost about £37. I've been in touch with the company and now have the spring, which cost £9.80 ex postage. Have taken the stock apart from the barrel, but can't see how to get the gun stripped back further to put in the new spring.

Gun appears to be held together with rivets, and I don't know how to easily get them out - and replaced again for re-assembling the gun afterwards. Can anybody advise please? We're not convinced the old spring is past it, as it doesn't look too different from the new one. Party Next Door Two Datpiff Er. Any suggestions as to what else might be responsible for the lack of pith in the last few years? The gun used to be a very useful weapon against all kinds of vermin, but now barely troubles crows as close as 20-30 feet away.

Many thanks in advance, mjanderson. There are 2 pins (not rivets)through the breech block. Dot Net 3.5 Offline Installer For Windows 10. Leave the one alone that is through the jaws of the cylinder, but using a suitable flat headed drift, tap out the one that holds the cocking link in the breech block(the shorter of the 2 pins) Then pull the cocking link forward and remove from the slot in the bottom of the cylinder Then with the muzzle end of barrel on a piece of old carpet, press down on the breech block and unscrew it (with care over the last few threads) Also take care not to bend or damage the trigger!! Pull out the piston and make sure the piston head is still Ok and lubricated.

If it is dry then that may explain the low power. I say this because even with a tired spring, the Cadet Major should still perform OK Put a small amount of grease on tail of piston and push the piston back into the cylinder with the slot correctly aligned for link to fit in. Put in new spring. Screw back in the trigger block. You will not find this easy because new springs are often stronger than they need to be.

Persevere using a leather glove to protect your hand. Then put action back into stock and away you go. Many thanks Rob M, pennineway, Chandlers and christy for your very helpful info. Sorry its taken so long to respond. Yesterday morning I discovered, purely by chance, that the curved end unscrews. Did it very carefully, and out popped the spring and a short flat-headed pin/bolt which was fitted into top of spring. That was all that came out, and that was all I had time to do with it till much later in the day.

When I got back to it, and compared the old and new springs, I think I've got the wrong spring. The new spring seems to have a larger circumference than the old one. It is longer too, but then it hasn't been squashed up inside a gun for about fifty years. It was T W Chambers who sent me the spring, and the second person I dealt with there assured me the gun is a Cadet Major. I thought till then that the Cadet and the Major were two different guns. Be grateful if somebody could explain the difference. I think the serial number is CA 67970, with the numbers not being particularly evenly spaced.

In Praise of the Cadet Major; If this is your first visit. God Of War Utorrent. I recently purchased from a local auction site a BSA Cadet Major. Serial number CA53163.

What I assume is the piston doesn't seem very willing to come out, and I think I'd better lubricate it before I do anything else. Any suggestions gratefully received. Thank you all again. Thanks Rob M. Our gun has an adjustable rearsight, but it looks different from the one shown on T W Chambers' diagram on their website. Their Cadet Major rearsight seems to have a bit sticking up in the middle.

Our rearsight is squarish, with a notch in the middle along the top, and a toothed wheel encased in the sight. The wheel turns round to raise it up or lower it to line up with the raised up sight at the front of the gun. Hope that makes sense. Apologies for my virtual ignorance in this.

Hamish at T W Chambers replied to my email, and says springs are slightly different now because measurements all metric. Major spring is 9.25' in length with 30.25 coils and Cadet is 7.75' in length with 27.5 coils. I've emailed back saying our spring is a wee bit over 7.5' long, and has (we think) 28.5 coils! Really beginning to wonder what model of gun we've got - though I'm pretty sure it is a BSA at any rate. Thanks again for your help and, yes, I'll keep you posted. Have just discovered rearsight which looks the same as on our gun - on the Airsporter MK2! Chambers' website diagram shows the Cadet rearsight as similar to what I'd think of as 'frontsight' on our gun.
