Cricket crapped today! (repaired 6/30/14)
I was doing some chronographing finally with my .25 Cricket. All going well when suddenly the gun wouldn’t fire, just a soft click inside the breech mechanism. Pressure was good (maybe 200 bar) and had been shooting JSB Exacts at about 885 fps just prior. Anyhow, I thought the reg or hammer were stuck. Cocked and tried a couple times, then reduced, then increased HST, to no avail.
I opened the HST screw and the hammer and a small pin maybe .100 “x 1.25″popped out. All the air emptied. I reassembled, cocked the hammer, refilled the gun. It held pressure fine, but failed to fire, giving the soft click instead. When I recocked, all the air emptied out of the tank again through the breech mechanism.
Failed seal/o-ring in the release valve?? I can’t fine a hi-rez pic of the exploded parts diagram to troubleshoot. May send it back to Topgun Airguns if I can’t fix it, unless there’s a better place to get service.
This is my second failure with this gun One of the main o-rings on the gauge end of the tank dissected under air pressure leading to a slow leak. I’m wondering if I need to do a preemptive strike on any other parts??
When it’s working, it;’s a tack driver, but I’m a bit pissed about dependability.

It does sound like broken valve…. if the valve was good it wouldn’t be dumping all your air.
undo your trigger linkage, take the 2 screws out that hold the valve to the breach, slide the air tube and valve assay out look at the valve and see if the pin is protruding. if not thats what came out.
Several hundred shots through the gun. Don’t know about the broken stem, though that makes sense, but the pin that came out seemed to be polished on both ends, didn’t have a broken appearance. I really need a higher rez parts diagram so I can see what’s supposed to be in there. Maybe detailed disassembly instructions for the breech mechanism.
May be a broken valve stem? A five minute fix when you get a spare if that’s the case. How many shots through the gun?

Dislodged/broken firing pin is a very common fault for Crickets. No need to take air tube out, just unscrew valve and inspect. Dealer is probably aware and will supply spare. Before unscrew Valve Spring Tension disc (perforated aluminum) take note of its position so you apply same VST after the repair.
