Fellside Posted August 12, 2023 Report Share Posted August 12, 2023 I have recently bought a weihrauch HW98S for my son’s birthday. Had great fun plinking yesterday with the birthday boy and his school pal - milk cartons full of water, tin cans, targets etc. etc. All good stuff. However, I noticed after about 50 shots that the stock was loose. I tightened the stock retaining screws. That should have been job sorted, however the screws continued loosening. I noticed they were beginning to slacken off after only about 20 shots (?!). I have had springers since I was a teenager and appreciate the need for regular checking / tightening of the stock screws. However this rifle seems to work loose very much quicker than anything I’ve known. Any advice re sorting this would be much appreciated.

Newbie to this Posted August 12, 2023 Report Share Posted August 12, 2023 Low strength thread lock Quote Link to comment Share on other sites More sharing options...
enfieldspares Posted August 12, 2023 Report Share Posted August 12, 2023 PTFE tape or even just a sliver of a matchstalk. Screws that loosen easily are usually because they've been undone often and the thread in the woodwork has become worn IMHO. Quote Link to comment Share on other sites More sharing options...

Fellside Posted August 12, 2023 Author Report Share Posted August 12, 2023 Thanks very much for the replies so far. It is a brand new gun and I have considered returning it. However, if there is a quick easy fix, this may end up being less hassle than returning. The idea of a loctite type solution appeals at the moment. I have also wondered if there may be some manufacturing grease left on the threads. My current thinking: cleaning the threads with isopropyl alcohol and applying an appropriate type of loctite may sort. Thanks again for the help folks! Any more ideas - please chip in.

oldypigeonpopper Posted August 12, 2023 Report Share Posted August 12, 2023 (edited) Hello, is it missing the retaining spring washers as noted on parts list Edited August 12, 2023 by oldypigeonpopper Quote Link to comment Share on other sites More sharing options...

Just had a look - and the spring washers are present. What I did notice however, was a lot of black grease on the screw threads…..?! Odd for them to be so heavily greased. A trip to Halfords for some degreaser and loctite tomorrow. I will see if that sorts it. Quote Link to comment Share on other sites More sharing options...

scarecrow243 Posted August 13, 2023 Report Share Posted August 13, 2023 Hi only use a drop of Loctite on the threads too much on the threads will make it harder to remove the screws if needed Quote Link to comment Share on other sites More sharing options...
ph5172 Posted August 14, 2023 Report Share Posted August 14, 2023 If your going to the trouble of getting thread lock I would just be posting it back to the gun shop Quote Link to comment Share on other sites More sharing options...
miki Posted August 14, 2023 Report Share Posted August 14, 2023 (edited) I'd agree here that they shouldn't be coming loose. Something is wrong. Lots of grease sounds like the suspect. This will cause the wood to soften (i'm assuming the screws are into wood ?) If they are set screws into a nut, then a degrease and a small amount of low shear locktite (222) will work.

Fellside Posted August 14, 2023 Author Report Share Posted August 14, 2023 Thanks all - much appreciated. Latest. I have now thoroughly degreased all relevant threads - tooth brush with detergent, dried off with kitchen roll and repeated several times. This has rendered the threads very dry. I have now reassembled. There was a very different ‘feel’ when turning the screws back in. Very grippy with much more frictional resistance. I haven’t had a chance to try the gun as it is currently raining heavily. However I do expect an improvement. If it needs a little touch of mild loctite, I now have some at hand. Fingers crossed I think it should be sorted. Quote Link to comment Share on other sites More sharing options...
Longbower Posted August 15, 2023 Report Share Posted August 15, 2023 Degreased threads , and spring washers compressed , should do the job . without the thread lock. If they start to unwind , use just a touch . Good luck. Quote Link to comment Share on other sites More sharing options...
