Idiots guide to classic airgun strips (pt 1)

[ggggr]

This is a late model Senior. Remove grips and rear sight. Remove barrel catch stop screw,barrel catch pivot and barrel catch. Watch out for barrel catch plunger and small spring. You can get to the piston washer on these, premiers and junior mk 2 without stripping the trigger (Hurricane,Typhoon and Tempest) but go for the full strip. Remove both trigger guard pins and trigger guard with a 3/32 pin punch. Remove trigger pin and trigger,sear and leaf spring should come out (note positions and that trigger hooks into sear). Remove barrel pivot lock screw and then pivot screw.Slide cocking lever out of slot and then unscrew endcap (I usually use the barrel as the cap is not usually tight--If it is then use something else. Withdraw mainspring and piston. Piston washer is a phosphor bronze ring that could be changed for "O" ring. Change breech washer if required, These were leather with a little brass bush but the usual Webley one fits, round end to the barrel.Clean and lube. Replace piston, spring and endcap. Locate cocking link in slot and replace barrel. replace pivot screw and lock screw. Put leaf spring up into trigger housing,put trigger into the sear and slide up into housing. Put guard on and then locate and replace all 3 pins. Replace barrel catch plunger spring and plunger and then barrel catch and screw. Replace grips and rearsight.



None cocking Webley Senior-----taken form what I posted on a thread recently.

"Ok. Here is what to do.
You have removed the mainspring? Put the guide back in and leave the barrel and linkage off the gun. Slide the piston back with a screwdriver or similar. Hopeully the piston should engage.
If it doesnt, then remove the guide and slide the piston a bit further back and see if it engages. If it now engages, check to see if you have the right piston in it. A Senior one should have a bronze ring as a seal. Mk 1's have a leather seal and Premiers and later guns usually have a Ptfe seal. All the pistons will go in but they will not work.
IF a new sear has been fitted at some point they sometimes need bit of the holding face grinding away to allow the piston to engage.

Assuming that the piston engages while you have the guide in, then try to push it forward a bit against the sear and the sear should hold.

If the sear does not hold the piston then either your sear is worn or the holding ring face on the piston-- Or both.

If with the guide in the piston does engage then that would suggest worn linkages/ cocking shoe, or the fulcrum on the cylinder being worn.

Usually bent pins are not the cause of a gun not cocking, but rather a symptom of people using excessive force to try to get the gun to cock.

More often that not, the problems start with a worn cocking shoe.

I will assume you have got the sear in the right way round. with the high side to the front of the gun and the lower more rounded side to the breech."
