HW100 Disassembly and anti tamper removal.

Sorry about the re-upload, had to fix a audio issue, anyway I got the Adjustable hammer spring kit from HW100 tuning and ill be fitting it and a seal kit from him in the next vid.

Thanks very much for going through this procedure for us all, I have just stripped my rifle down and give it the full HW100Tuning treatment, my rifle is now back to its former glory, powerful & accurate. It took me most of the day, but your video helped enormously. Once more, many thanks.

[@sub12airgunners]

That's great, exactly why we started the channel to help people like you that want to have a go 👍 nice one

[@MartinHealy]

So glad to see you giving the brilliant HW100 some treatment. Another really great video - thank you so much for sharing your knowledge and skills. Looking forward to seeing Part 2. All the best, Martin

Is it recommended that you're better off to fire off a HW100, now and then, rather then leave it sitting for half the year, to prevent the hammer spring from compressing a bit, or the regulator settled down, due to lack of use? or does it not make much difference if its fired regularly or not? How regularly should a PCP like the HW100 be fired to keep everything stable/power from dropping? Fabulous informative video, dunno how you can remember where everything goes! 🤪

[@paulec5864]

On the later HW100 the anti tamper can be removed by drilling with a 7mm drill bit inside the lock tighten adjuster to clear the riveted over end of the hammer spring guide. Then when removed heat the adjuster to free off the lock tight. No heat damage to the spring this way. The old adjuster can be refitted with a cut in screw driver slot or the spring shaft shortened to about 9mm on the hammer so a new adjuster with the Allen key slot could be used.

Best break down video I have seen so far for this lovely rifle. Thanks for the effort.

[@sub12airgunners]

Thanks mate, glad you enjoyed it. Thanks for watching.

[@stumorgan7725]

Great video, very helpful thank you, what is the best size punch to use for knocking out the cocking arm pin? Many thanks

[@tonyrebelo3038]

Nice one Jake, I really enjoyed that. Good old German solid state engineering! The design certainly has stood the test of time, and I have no doubt your improvements will make it a much better rifle all round.

[@Happy-Me.]

I'm so glad I have Weihrauch guns. So well engineered/made and consequently so reliable!

[@sub12airgunners]

They are very nice little rifles. Thanks for watching.

Hi. A great video of the strip down. However, unfortunately I’ve managed to lose the spring and larger ball bearing that goes into the indexing assembly. Is it possible to give me the sizes of these two parts or a part number so I can replace them please? Also while I had it all apart I decided to soak the hammer housing in degreaser but it has reacted with the surface leaving a white powdery film. I’ve tried lightly rubbing with steel wool to some improvement. Any suggestions as to how I can recover the shiny finish? Any help would be greatly appreciated. Cheers

[@Happy-Me.]

Great video. I've recently Chronographed my HW100 to find that it's lost a bit of power from last year. She's now down to 10.5 ft lbs from 11.4. The gun has no leaking etc.

[@sub12airgunners]

The hammer spring has probably compressed a bit, or the reg has settled down, neither are uncommon in rifles that have been sitting for a while, I would recommend contacting HW100 tuning if you want your rifle serviced, he knows the HW100 better then anyone. Thanks for watching.

[@Happy-Me.]

@@sub12airgunners I've just got back from my Gunsmith. He's done a lot of these before so he says it's not too big a job.

[@johnbonnici8048]

Hello Happy Me. My 2 1/2 year old Hw100KT has done just like yours but power is down to 8.3 ft/lb . My gun also has no leaks. Have you solved your problem and if so would you kindly explain to me how it was rectified . I will shortly be taking it to my gunsmith and your help will be greatly appreciated. John Bonnici.

[@Happy-Me.]

@@johnbonnici8048 My Gunsmith disabled the anti tamper so I adjusted it myself with a chronograph. It's running at 11.5/6 now. I don't use the gun often as I love my TX200 but I've been told to let off a few shots every now and then otherwise the power will drop again.!

[@johnbonnici8048]

@@Happy-Me. Thank you for your attention and reply. I'will point this out to my gunsmith. My gun reduced power even though I shoot it almost daily . Did you do any other adjustments apart from the hammer spring tension eg. Regulator pressure and O'ring replacement?

[@weirhauch1002]

Wonderful detailed video 👍waiting for part 2 please🙏

[@greg105]

Hi there. I am in the process of replacing the receiver on my hw100. I am at the stage of removing the indexing arm spring. I am using a 1.5mm Allen key with no luck. Can you help please? Cheers

[@aranhw1007]

I'm going to be removing the anti tamper on mine soon,was wondering do I have to replace the hammer spring at the same time or just use the original?.

[@greg105]

Hi. Regarding the bottle adapter. Is that a dr.bob’s version? From the pics on eBay his has a male thread into the bottle. Which means no valve. Is this correct? Cheers

[@sub12airgunners]

no this one is a different one not dr bobs one but i don't think they are available anymore so you have to use the dr bob adaptor😀

[@philbate5555]

Love the look of that gun jake, challenge for you ! Could you make me one of those stocks in blue. Lots of useful information there mate , love all you're posts.

[@jezza42]

Excellent video, thanks for sharing. What Allen keys is it you use please? They look really good

[@sub12airgunners]

EDS allen keys, I got them from eBay. Thanks for watching.

[@jezza42]

@@sub12airgunners great, thankyou 👍

[@greg105]

Further to my previous comment, could this require a 1.3mm Allen key and not 1.5mm?

[@squirrelhunter4life909]

where can i buy the green stock and the Weihrauch HW100 Buddy bottle conversion kit ,I went to the form website and could not find the stock

[@sub12airgunners]

I don't think you can get the kit anymore but you might try Livens guns

[@Tim_Bassett]

Really clear video - keep them coming :-) Glad to see a dremel make an appearance

[@tonyrebelo3038]

By someone that knows how to use one Tim ;p

[@shaunharris3690]

Hi what size Allan key for the hammer grub screw?

[@johnpaullus6649]

Hi, is that a Jacko kit or Dr.Bob buddy bottle kit? Do you know if you can still get the Jacko kit and if so where can you purchase one? Thanks...

[@sub12airgunners]

Its the Jacko one, he does not sell them anymore, but you can sometimes see them pop up second hand but not often, Thanks for watching.

[@mkmk0081]

From where i can find this kit ??

[@tctokis]

Hi this is for a fac rifle or 12ftb

[@jeffhello1444]

Nice work 👌👏

[@myadventureman2636]

Nice adaptor..very presicion❤

[@sub12airgunners]

thanks for watching 👍

[@pmurp9x]

Fantastic video, but i think it showed that i don't have the confidence to take it on myself 😒

[@secondfirstsecond]

Really, that placement of gauge and plug destroyed the aesthetic. Why didn't they move it down under the stock?

[@sub12airgunners]

Don't know for sure, but if they were both in the bottom it would push the bottle out a little further, or most people have rails fitted so having the fill port and gauge on the bottom would limit the amount of pic rail you could mount on the bottom. Thanks for watching.

[@secondfirstsecond]

@@sub12airgunners Ive seen one with plug at the bottom and gauge on the right side, fit nicely.

[@petenikolic5244]

That Bottle adaptor is a Torx NOT an allen

[@sub12airgunners]

yes but it can be removed with an allen key with no issues and more people have an 8mm allen than Torx bits😀

[@brianjenkins6868]

That must be the worst pcp air rifle design ever.

[@sub12airgunners]

Not a fan of the HW100? me neither to be honest, the 2 piece block is a bit off putting and the use of cast components doe not sit well with me, but saying that I was surprised at how well everything fit and it was nicely finished, just not my cup of tea. Thanks for watching.
