Hammer, brass bushing and valve pin wear
Grabbed a few images from my Vulcan 22 during its early break-in.
You can already see how the parts wear even early on.
The valve pin is developing a flat spot where the hammer strikes it. I expect this will expand until it reaches stable condition.
I wouldn’t be surprised if this is part of the early shifts in energy output.
Tip of the hammer looks like it includes an insert. I suspect this is a harder material than the rest of the hammer.
There is an odd pit at one point of the tip shoulder.
The brass bushing in the 0.22 is used to create a free floating hammer strike. It stops the spring’s forward motion
when the bushing hits the breach housing. Then the hammer flies forward freely. This debounces the hammer strike
to improve air efficiency. (Apparently this isn’t done on the larger caliber version(
However, the bushing takes a horrible beating and makes noise. If you look on the forum, there are reports of
a brass bushing that fractured and others with visible brass shards in the hammer chamber after a few hundred
rounds. I like that we can have a free floating hammer, but this promises to be a point of failure.
My gun has only about 100 rounds through it and already there is visible wear along the periphery
of the brass bushing.
Also galling where the spring engages the brass bushing.
I don’t have a Delrin replacement, but have instead encased the entire bushing in a rubber bumper. It reduces the
noise, cushions agains the impact and should help with keeping the part from wearing. We’ll see how
long the bumper lasts. I think an acrylic panel to allow continuous inspection is this weekend’s project.

I didn’t realize it had been out that long. You are right that any major issues would have surfaced by now. Thanks for your comments.
Vulcan has been on the market for like two years. No major issues were reported and if any – Evgeny addressed them. That should speak for itself.
Shooter3,
That makes sense that ware is common, my concern is that ware is necessary for a pellet to seat properly. I can understand that a regulator needs to be seated/broken in. But is is loading a pellet the same? Are there issues with the design, materials or quality control? I’m just asking before spending my hard earned $. I understand that there isn’t a lot if history for newer airguns. I appreciate your input.
Well, I would not consider them like that. Moving parts will wear because of the friction. In Matador you have the same situation: hammer is riddled by the valve stem.
I don’t know but do these issues seem like a basic design flaws? I’m having second thoughts on pulling the trigger on a Vulcan purchase.
:rofl: just askin’!
you need to buy another gun to have a spare action
:rofl:
another Vulcan of course. just don’t tell the missus, she will not notice
Speaking about wearing, how about the half-opened tunnel in which the hammer works? Are there any signs of wearing?
the middle pin is steel. i have to look again but on .177 it is steel. in my opinion it is better to have brass on the side where the o ring is, brass can wear, imagine if you bend yours or its mount is out of alignement, or the magazines not aligne it will mess up your barrel.
who wants that.
just like when I watch videos on youtube with steel tools going into changing barrel/breech o rings or messing with regs.
get brass tools or plastic for that. or toothpick
I think pellet probe should be made of harder material. Why not stainless steel?
get a spare of
72
71
70
78
66
66 wears a lot.
yes I bought a spare valve stem too. might be a good idea to have a spare teflon reg seat too. but that can be polished.
Spare hammer spring too also good to have.
I think they could make some money if they started selling tear and wear stuff online. People would not mind paying extra, the pricing was OK too FYI.
the valve stem is very robust, and it is floating so should last if you don’t abuse it
I got spares for my peace of mind.
How about the valve stem? It is made of plastic. I know there is a problem with valve stems in Matadors – they simply break. How about Vulcan? Have you ever heard about broken valve stem in Vulcan?
the pellet probe mount is worn on mine already. will need a spare soon.
brass paste everywhere. oil helps but not much.
was it 3000pellets through
I wish there was a web shop with spare parts, stuff like that.
there is a updated website http://www.airguntechnology.com but no online shop.
Careful with your requests, Zonk.
You may see “parts” you wish you could un-see. :suprisedn:
