holloway Posted June 28, 2019 Report Share Posted June 28, 2019 I have just been given this air rifle and thought i would see if i could renew the mainspring .The question is how do i get the trigger unit out to gain access to the spring ? i have removed the 2 pins holding everything in place at the back of the cylinder and still cant see how it comes out .Do i need to take the trigger unit apart ?. Any help welcome . Quote Link to comment Share on other sites More sharing options...
snow white Posted June 28, 2019 Report Share Posted June 28, 2019 Photos will help. I had one gun that you took the two pins out then undone the back couple of turns and the trigger assemble dropped out but can’t remember what it was❓😩 Quote Link to comment Share on other sites More sharing options...
sportsbob Posted June 28, 2019 Report Share Posted June 28, 2019 I could be wrong here but after looking at the diagram for that air rifle it looks like the trigger block is what is holding the spring in . If that is the case it would probably be safer to put the pins back in because if you do get the trigger block out the spring which should be under pressure will escape at speed along with the spring guide and a washer or two. It looks like you need a spring compressor with a forked tool to firstly compress the spring then remove the pins and trigger block, after this you remove the tension from the spring compressor and the insides will now be outside.

That all makes sense ,i did replace both the pins whilst i tried to figure it out i will try to compress the spring ,many thanks for that.

If you haven't got one then YouTube has vids on making Spring compressor Quote Link to comment Share on other sites More sharing options...
figgy Posted July 4, 2019 Report Share Posted July 4, 2019 (edited) Iirc I gripped the end in-between some wood gripped tightly in a vice. Pushed down the tube and turned untill it unscrewed. If you keep your weight pressing down on it you can release it slowly. Have used the rounded end of a file handle to lean on and compress the recessed sleeve to take the tension of the retainer pins on some in the past. Think I oy had to press the trigger on some to remove the innards. Hope you figure it out. Edited July 4, 2019 by figgy Quote Link to comment Share on other sites More sharing options...
