My 98 has developed a slight pause/bump just before the end of the cocking stroke. Just before the spring is fully wound up. It is noticable bump but doesn`t not change the shooting aspects of this gun. Everything is fine on the firing cycle.
Anyone experienced this. Thanks for your help..

Could it be the trigger sear engaging ?

Hello Pellsby, IT is about that time I would guess although I have 2 other Weihrauchs now and they are smooth cocking to the end of their cycle.
It feels more like something to do with alignment..but it is mechanically always at the same point..

It sounds like the spring is broken near the end, 1-3 coils in. I have experienced this a few times. Surprisingly with little effect on performance. The bump is the feeling of the two broken ends passing over one another as they compress.

Could also be the cocking shoe, do you by chance have an aftermarket spring kit in it?

Could be a few things. Wish I had it in hand to feel it tho. So the last 5% cocking of stroke is about the last 3mm of piston movement which would narrow it down some, or is your 95% just a guess? So it could be a broken spring as mentioned earlier, or maybe the rod is cocked a bit and catching on the guide or trigger. Could be the trigger is dry so there's some friction so you have to force it to make it latch. Could also be friction in the tube causing piston skirt friction, but that's usually starts just after where the barrel is bend 90 and gets worse as you go for a stretch, then lets off a bit before the trigger, so I'm guessing not that but not ruing it out either. Then there's the friction in the cocking slot, which if the slot is uneven can make a bump like feel. So I'd check it again and try to measure better. How long is the bump, how much further past the bump until you can't cock any further, then how much the piston goes forward before the trigger holds it. Basically trying to see the distance between the sear holding position and the bump. Plus how long said bump lasts, like is it a short bump like it was catching something and releases right away, or it takes some time to pass over it? And does overcoming the bump need extra cocking effort? Is passing the bump smooth or scraping metal to metal, or just a feeling and/or noise? I would take it apart first thing but up to you.

And the winner is SUPERJETBRYAN, :ANAL: :rolleyes: :rolleyes: :drinkers: , the spring was broken in 6 places,,, and the "/%7%55 thing was still shooting well, although 40 FPS below original FPS..

HW777, Joe, is there a problem with aftermarket kits and the cocking shoe?

Six?!?! Sheeze! I would've thought a nice German spring would've lasted for life. Oh well. So how old is it and how many miles? Original owner? Gotta pix of the remains?

Ken, I believe that there had been quite a bit of dieseling for the prior owner, he said he put through maybe 2000 shots before I got it but it was diesling once in a while.

Thanks..

I was the original owner of this rifle. It did not diesel. It functioned and shot as it should. I say this only as clarification for readers.
