Question/input on the hw30

Jump to latest Follow Reply
From what I gather the idea of the insert was good as it stopped the upper surface of the cocking arm scraping the underside of the cylinder, however, HW added a fairly strong spring under the insert and this caused the cocking 'shoe' end of the arm to scrape along the inner edge of the cocking slot moving the galling to that location.

I gather best results came from removing the spring from under the insert, polishing the shoe and applying lube and freeing up the riveted pivot between the short and long links allowing the it to articulate more freely.

It seems odd that the cocking system is essentially the same on the HW30/HW35/HW50/HW99S, yet the older guns don't seem to give as much issue.

What is interesting is that I've mostly been reading about the galling issue from people that have either the hw50/99s, with very few mentioning the issue with guns like the hw30 or the 35. Don't know why that is however. Could be pure coincidence.

That may be due to the hw50 popularity as a hunting gun. I suspect they experience more adverse field conditions than other Weihrauchs. During rabbit season in England, probably thousands of hw50's are hauled through the woods every weekend.

There can indeed be a problem with galling. Fortunately, it is easily rectified. Simply disassemble the cocking linkage and polish the areas that are rubbing. Apply a little moly grease and all will be well. I've done this to two rifles and have never had a problem since.

That's the thing. I don't want to disassemble it after brief use. For a start I just want to buy a rifle and a scope for it and just roll with it without having to tinker with it in order to get it right. Of course if galling occurs after long term use then it will most probably be okay cause I will use some kind of tuning kit in the long run.

The galling issue is real. It is on every airgun site and goes back maybe 5 or 6 years. I mean just Google HW30 galling. I have an HW30 which is ten years old and still shoots like a laser despite having the crap shot out of it by every neighbor, kid, woman etc that came over. Mine has no galling issue. 

The galling does not appear to be anything that was ever fixed. It was one of those "keep moving people, nothing to see here" type manufacturer issue addressing for years. Way too many out there to recall and too costly to retool parts, alignment etc. Krale had enough complaints they worked with Weihrauch in this email below. The fix was more a Band-Aid and many said the fix just shifted the problem elsewhere.

Here is a Youtube video explaining the galling on an HW50 and how the fix doesn't work. He takes the whole gun apart and explains the best things to do about the galling.

Dear sir,

Thanks for your email. Please find attached a photo of the recent Weihrauch HW30s cocking arm. The plastic slipper inside the cocking arm should be preventing the damage.

Met vriendelijke groet / Kind regards,

FWIW, My HW95L is absolutely soundless during the cocking cycle until the piston rod end contacts the trigger. I know the 95 uses a different cocking mechanism than the 30 and I suggest that you may want to check one out, (95), before you purchase a 30. I have NO knowledge of the 30 and just my thoughts. Good luck with whatever you choose.

From what i've seen and read so far the hw95 in all it's forms has a one piece cocking arm instead of an articulated one. This was first implemented in the Hw80/beeman r1 and has since been a staple in more modern weihrauch designs from what i can tell. The nice thing with it is that it makes the cocking cycle much smoother... and that it also takes care of galling as in; there is no galling whatsoever in the rifles using a one piece cocking arm. Tbh, i'm also looking at the hw95 since summer when i made my last post. Still can't really decide however. I'll look more into it!

I am aware that it is an issue. I've searched through here and GTA to see what people have to say about it. Thing is, when it comes to it, most people refer to it in the case of the HW 50/ HW 99s. I've rarely seen threads concerning galling on the HW 30 and/or the HW 35 (whether it's the standard or the "e" version). Maybe the issue is more closely associated with the HW50 for some reason? Just contemplating, I don't have any first hand experience with either of these rifles.

I believe HW gave more attention to details on the older guns. They had better tolerances, polishing and lubricating regarding the cocking shoe grinding on the slot where the cocking arm passes thru. Like everything else out there manfuacturers are struggling to keep selling price points down to be affordable and profitable.

Thing is weihrauch rifles are currently quite expensive pieces. What is also quite interesting (about galling more specifically), is that it is mentioned a lot for guns like the hw50 and maybe even the hw30 whereas it is rarely mentioned for guns like the hw35 (standard or export version) could it be that they pay more attention to detail on some guns?

The HW35 has not sold in anywhere near the volume the HW30 or HW50 do since the introduction of the R9 chopped the HW35 sales to almost nothing. The bulk of the HW35's out there are old and either didn't have the issue because they were made decades ago with better tolerances etc or have long since been fixed. The HW35 is kind of an oddball gun with no real direct competitor or true market.

I see! One more thing though; does the delrin/plastic insert that weihrauch implemented for the hw50 work/fix the issue. The reason why I'm asking is because some people say that it doesn't but whenever I read for fixes on older versions of the rifle I see people recommend a plastic insert.

You really have to decide that one for yourself. Mine does not have any galling and I had it apart at least half a dozen times doing tuning. I have not been inside any other ones. The opinions vary quite a bit on that fix. You could call around to a couple of the tuner/mechanics that do work on those guns. Pretty much all of them will give you the straight dope. 

Worst case scenario appears to be 15 minutes once you have it apart as long as you know what you are looking for and have a little mechanical aptitude or can follow Youtube videos.
