Need HW95 help - Gun is stuck cocked and will not fire or decock

[12gsnapcaps]

Hey all,

I've just fitted a TBT kit to my HW95.

Ive gone to cock the gun, which it does, but i cannot fire or decock the rifle.

The safety catch is stuck and i cannot turn it off. Pulling the trigger does nothing.

Any ideas?

Get in touch with TBT, Nick or one of his team will talk you through it, they really do know their airguns.
If it's spring bound try cocking the rifle and pulling the barrel as far back as you can, then whilst pulling the barrel back as far as you can, use the other hand to push the safety button through.
Is it simply a tune kit or have you used their piston/seal extension to short stroke it?

 

[12gsnapcaps]

I think i may not have correctly installed the safety catch or perhaps the trigger, although i followed a video to the letter.

It has the short stroke kit.

I've tried your suggestion but it doent work, that safety catch it stuck solid

I guess you did put the little spring back on the thin end of the safety catch?

Ok, i've managed to de-cock it now. Now it cocks, but it fires when I press of the safety catch

Yes

It's a while since I pulled a HW to bits, but check that the 2 pins on the trigger block through the cylinder are fully seated and speak to TBT tomorrow.
Whatever is wrong I am pretty sure they will have encountered it before

 

[12gsnapcaps]

Yeah i'll give nick a call tomorrow, thanks anyway Lancaster!

Hey, thanks for checking up. Spoke to Nick at TBT but we still haven’t got to the bottom of it. Still having the same issue with the safety and the gun not firing with the trigger but firing when the safety’s pressed last email to him was to ask if I needed to fit the stock but haven’t heard back.

 

[12gsnapcaps]

I’m thinking maybe the rear stock screw acts as a restraint to the back of the trigger unit and will stop it falling off the safety catch? Dunno. I would have though the gun should work without the stock being fitted

I've got a HW 80 that will have the same Rekord trigger, but has a different cylinder size and swept volume, it's also got a TBT short stroke conversion fitted to help keep it the right side of the law..
If I get chance tomorrow I will drop the cylinder and trigger unit out and have a look to see how they all tie up, like I said it's a while since I pulled a HW to bits but they are easy to pull apart and put back together.

Try stripping it again, and assuming you added power washers, try removing one, make sure the trigger is cocked before re assembly, and ensure the safety catch moves freely before tapping the pins in to hold the trigger unit, it sounds like it may have a touch to much preload.

Hi Hornet. I don’t have any power washer installed. I have the top hat, slip washer and spring guide. the trigger is cocked before re-assembly. Nick told me to fire it after reassembly. Nick also said the safety catch needs to be locked upon reassembly not move freely, although I’ve tried it with both, free and locked, and the issue remains for both.

I had something similar / the same happen with my HW95 when I stripped it for a clean and polish. I traced the 'fault' (my error) to the little rubber/plastic U shaped clip/spacer that sits on the cocking arm between arm and cylinder - I'd put it back in the wrong place
I seem to remember that it had fallen off during disassembly, fortunately I noticed it on my bench, then had a choice of two places to refit. Obviously I chose the wrong one.
Once I'd corrected that mistake it worked fine.
From memory (poor at the best of times) I think with the U clip/spacer in the wrong place the cocking shoe sits too low/high and everything locks up.
Best of luck and mind those fingers!

 

[12gsnapcaps]

Hi Grumpy, haha - sounds like something I’d do! I think mines in the correct orientation but I’ll add it to my list of things to discuss when I try and ring Nick again later today.

It should be noted, the TBT after sales service (I.e being able to speak to Nick) is fantastic. Any issues here are totallly to do with either my skills or my gun, nothing at all to do with the TBT kit. I fitted a TBT kit to a pro sport last year and I can now shoot the primers out of shotgun carts at 50 yards.

Nicks got no ideas.

Could anyone point me to an install video detailing the trigger and safety installation in depth or take a video or photo of their own?

Some people saying the safety needs to be free when you install the trigger unit, nicks saying it needs to be pushed all the way in and then be captive.

Whatever I do, I can’t get the damn thing to work, been at it for three days now.

Try pulling it to bits, warm up the piston extension in hot water, take it off and put the original seal back in, put it back in the stock and try it again, see if it cocks and fires, make sure the cocking shoe is lightly lubricated and sitting flush in the groove.
The pins only drift in one way and need a jiggle to get them all the way in.
Put the front pin in all the way and put the safety with it's spring back through it's hole, push the trigger unit back into the cylinder and then put the 2nd pin in.
If all works as it should re-try with the short stroke extension back in, if it doesn't then that is the issue, possibly spring bound.

The gun cocks and fires off I don’t put the safety catch in, so I don’t think it’s coil bound. When I put the rear pin in after putting the trigger unit in, should the safety catch be loose or pushed in and locked?

If it's de-cocked it should be under the pressure of the spring on the safety, so not loose, but certainly not all the way through in the ready to fire position.
