READ FIRST TWO POSTS. The Diana 22/23 +Webley junior/jaguar/ranger strip. These are all more or less the same gun except some have pins instead of nuts and bolts and different way of holding the piston washer on. You may remove the sights to prevent breakage. Undo the front 2 stock screws and the one to the front of the triggr guard and remove action from stock. Unscrew (remove pin) from cocking arm. I use a screwdriver with a gap ground into the middle of the blade to undo the nut. This nut is about 5/16 OD and is tapped 3/16 bsf if you need to make one up as they go missing a lot. Do the same with the barrel pivot. If you want to remove the plunger on the cylinder you will have to undo the little grubscrew and it may be peened over. remove the plunger and spring and clean up. If this spring needs replacing,better to take it to local shop to find match or send it to Nibbs otherwise he will send you the wrong one(they sent me two wrong ones).Using a small screwdriver, hook trigger spring of tang on end cap. You may have to tap endcap with a punch to remove from cylinder. Triggers sometimes seize to pivot pin and may need "plus gas" to free off. Undo pivot and remove trigger. Clean any old grease you can see in the back of the cylinder because this sometimes gets under the sleeve holding the spring in when it starts to move. Next find a socket that will fit on the sleeve and an extension bar to put on it. GO TO NEXT POST.
