How to fit a V-Mach tuning kit on a Weihrauch HW97K rifle [Step by step tutorial] Solves dieseling
Вставка
- Опубліковано 29 тра 2020
- You can skip the intro jumping to 3:35. Tutorial begins with the rifle completely disassembled. The fitted kit is rated at 16 joules.
Contents (serves as a step-by-step guide):
- 2:54 : Briefing on how to dissassemble the rifle
- 3:35 : List of materials needed for the tune up
- 4:40 : Instaling the new piston seal
- 5:05 : Fitting the piston sleeve
- 5:53 : Greasing the piston, the seal and cylinder
- 6:51 : Inserting the piston into the compression chamber
- 7:05 : Inserting the assembled cylinder into the action
- 7:22 : Assembling the cocking lever and the anti-bear trap
- 8:13 : Inserting two compression washers into the cylinder
- 8:38 : Applying grease behind the compression chamber
- 8:44 : Greasing the main spring
- 8:57 : Inserting the spring into the action
- 9:06 : Screwing back the rear block
- 10:11 : Screwing back the large bolt retaining the anti-bear trap
- 10:43 : Inserting the safety mechanism
- 10:52 : Mounting the trigger assembly (Actually, trigger unit disassembly is optional and the rear block may be easily screwed and tightened by hand. I have disassembled it for inspection, avoid damaging it and access the trigger mount hole for better leverage during the rear block screwing process)
- 11:38 : Mounting the stock to the rifle
- 13:52 : Fitting the scope
- 14:54 : All done - overview of the surplus bits (compression washers, nylon washer, oil, grease and the old spring and seal)
- 15:01 : Final comment
Considerations:
- Bear in mind that older rifles with a serial number below 1446649 use a 25mm piston seal. Newer units mount a 26mm one.
- Check your country air rifle power limits prior to buying a tuning kit and chronograph the rifle after the tune up to make sure it falls within your country regulations.
- When disassembling the rifle make sure you don't lose the safety catch spring. It has a natural tendency to fly away.
- The coking lever & trigger unit pins should come loose without too much effort. If you are struggling, try using the punch from the other side. (Same applies when mounting them back).
- Do not apply grease on the piston seal face. Only coat the sides very sparingly or dieseling may occur.
- The trigger mechanism can be a pain to install. Use two pin punches to align the holes.
- The oil supplied in the V-Mach kit is only for the exterior of the rifle. Do not use it in the piston, cylinder, seal or spring.
- Some people lightly sand the piston and cylinder after degreasing. I haven't done it and the V-Mach fitting instructions omits this step as well.
- The trigger unit may be left assembled during this procedure if the rear block is easily screwable an tightenable by hand.
Thank you for watching, hope you found it useful and happy field targeting. Any question/comment please feel free :-)

Good to see people using german quality rifles.cheers bud from uk.....
Thank you for your excellent video. It was to the point and informative.
Very educational video. I own the hw77 and hw97kt, splendid airguns! Will probably install a kit in my hw77...thanks
Thank you for sharing your tuning video, we appreciate it.🙏
Very well made video, you have a talent for it 👍
Thanks! I've been thinking of buying one of these rifles and trying to learn everything I can before spending the money.
Nice video and talk through! Well done and thanks for taking the time to make.
Much appreciated! Regards
Thanks for sharing. Just waiting for my 97K and scope. 😉
Good choice!
Very clear directions. Thanks for sharing. 🙏💐
Hello. I recently bought the hw 97. I thought it had 20 joules of muzzle energy. I chronographed it and to my suprise it has only a good 14 joules of muzzle energy ! I saw that my gunshop sells an "original" spring that gives 20 joules of muzzle energy. Do I simply have to take apart the airgun as you showed remove the original spring and put the new one in it to have an increase of energy ? Thank you for your help !
Nice video, very concise & will be useful for future reference. Thank you very much.
Hi, I have nearly watched all of your reviews. You are a great teacher. I have a question on my mind that I am seeking for answer for some time. I am planning to get this rifle. However, people keep telling that any spring power gun kills any kind of good scope sooner or later, even expensive ones, because of double recoil the rifle produces. Do you agree with that? Should I go with pcps? I dont want to destroy my expensive scope. Thank you so much.
Thanks for your kind words. The rifle does have quite a bit of recoil. There are scopes in the market designed to handle these vibrations. Actually updating the rifle with the V-mach kit, provided it is 16 joules and not more, helps mitigate a bit the recoil, i guess thanks to the sleeve.
Having said that, my nikko stiring is still standing after many shots. So i guess if que scope quality is good, I wouldnt worry too much. Regards
thanks
Did it make a nice differance when you shot it. I own a HW97KT also its brand new, do you think i should put one in mine and i hope i can do it, you made it look easy.
Great Video and well explained. many thanks.
Glad it was helpful!
Brilliant
Very nice , thank you.
🤔You forgot to say once you installed the trigger block back in the latched position and refitted the pins the trigger needs to be pull to release from the latched position otherwise you can't recock and latch the spring.
Bellissima carabina
What is your Nikko scope and where did you buy it? Really nice video!
Thank you! The scope is a Nikko stirling diamond 10-50x60. I bought it in the uk, and i went to pick it up taking advantage i was going on holidays. I dont remember the store I got it from though...
Buen video ! A ver si te animas u haces más vídeos del Hw97k. Yo tengo uno laminado en 5,5. Tengo montado un visor nikko stirling diamond 6-24x50 FFP. Reticula skeleton HMD. Lo tengo original, como viene de casa. Y es un bisturí. Si hicieras un vídeo de agrupación hasta los 50 metros estaría muy bien. Un saludo desde Barcelona
Gracias! A ver si tengo tiempo para hacer algun video más :-). Tu tienes pensado colgar alguno?
Saludos
Good video. Like and subbed.
Thank you 👍
Is it hard to load a pellet with the scope so far forward ?
Hello, yes, it is a bit tricky indeed, this scope is huge. You get used to it. Cheers
Thank you for video so much.. Are you in Arabic country?
How did you find the v-mach kit? Much difference? Cheers
Hello, here you can fnd the list of dealerships: www.air-rifle-tuning.com/v-mach/How_to_Buy.html
I ordered mine from www.versandhaus-schneider.de because I live in Barcelona and the shipping costs were reasonable. Regards
@@BarcelonaAustinA35 cheers brother. Did you find much improvement in the firing cycle? Regards
I think this kit is a must, provided it is installed properly. The sleeve arround the main spring helps minimize the recoil, and the accuracy increases too.
@@BarcelonaAustinA35 brilliant stuff mate, mine is very accurate standard but to twangy and a bit rough to shoot needs smoothing out
Yeah it is a bit rough indeed, make sure your scope can handle the recoil. That is why i wouldnt recommend any kit over 16 Joules. Too much twang will undermine precision. Happy shooting
Really informative video thanks! I own a HW97 kt, which is still very new and shoots great... Although I could get one of these kits in the future. I'm surprised you have such a powerful scope on your rifle, looks amazing though and I'm sure the image is very clear. Are you based in Barcelona? Was wondering what were the best "Campos de tiro" In the area?
Hello Anton, yeah the Nikko is really the best you can get! The ensemble is a bit heavy but the focal length is superb. In Barcelona there is the Olympic Shooting Range in Montjuïc which has nice views and a 50 meter gallery (tirbcn.com). Close to Barcelona there's one in Sabadell city and in Mataró. Regards
@@BarcelonaAustinA35 Okay great thanks for the info. I'm actually from Sabadell however their membership fee is expensive. I've been looking at the outdoor range called "can pique" By montcada up in the mountains which appears much cheaper. Thanks again!
I’ll check this one out!
@@BarcelonaAustinA35 One last question, where did you purchase your kit from? Have a great day!
Versandhaus Schneider online store (German). Cheers
Is the kit available for the hw77 also ?
Hi. Thanks for your comment, yes, there are V-mach kits for hw77. Regards
If you are going to be around Madrid someday, would you be interested in V-mach-ing my HW97k special Edition?!
I would be more than gladly to pay for your service.
I really think this air rifle is excellent, but a tuning kit would finish her off perfectly!
Let me know if you would be interested, if you are ever around Madrid...
Thx :-)
Hi, yeah, we could have a look together once the confinamiento is over, i’m in Barcelona. Regards!
@@BarcelonaAustinA35 Sounds great! That way I can break it in correctly, and with time. Then some months from now we can go with a tuning kit :-)
Till then, stay safe!
Sure! Tengo ganas de ir por madrid, hace mucho que no voy! Ahora que el ave es mas barato me escapare un dia cuando la situacion mejore, saludos
Et presque 4 ans plus tard, aucun retour puissance/précision sur l'installation du kit comme annoncé en fin de vidéo !!! dommage... 🤨
You dont have to remove trigger unit from the block .
Hi, thanks for your comment. How do you retighten the rear block then? (Minute 9:47 in the vid) I needed the trigger unit gap to align the rear block, i didint want to scratch the metal or damage the trigger. Regards
@@BarcelonaAustinA35 Mine is screwed by hand all way in , toothbrush and thinner to remove locktite from threds , fitrst time you can use adjustable spanner and rag or paper towell and grab trigger unit . 6:32 ua-cam.com/video/T8VU3Cw5AQQ/v-deo.html
Hi pal, what scope is that, is it a Nikko Sterling ? if so what model as I like Nikko Sterling scopes and really like the green turrets
Hi, its a Nikko Stirling Diamond Sportsman 10-50x60 with Mil-Dot. Its steep but worth every cent
@@BarcelonaAustinA35 Cheers pal it will look good on my Wiehrauch HW100S
Nicw to see you applied lube before you forced it in
Subbed and liked. How long had you been using this air rifle before you noticed these problems? I was thinking of buying one myself and I'm not so sure now.
Thanks Shaun. Unfortunately these problems began after only 2000 shots aprox without apparent reason. Probably they grease the components too much in the factory and it leaks to the piston seal. It is a shame the rifle doesnt come with V-mach quality seal and properly greased. However they have been building these rifles for many years and they have good reputation, it is regarded as one of the best spring rifles ( the trigger assembly is superb for example) so it may not happen to you, although dieseling is a common fault as far as i know. An alternative could be the TX200. Regards
@@BarcelonaAustinA35 Thank you very much for the reply and greetings from England.
Buenas donde se puede comprar este kit
Hola Rafa, comprala en alemania sin dudarlo, en uk te meteran un palo de aduanas. Recomiendo la web www.versandhaus-schneider.de
Saludos
Buen video, pero en español estaria mejor para los que no sabemos mucho ingles, ya que hay varios en ese idioma. Excelente visor, yo me tendre que conformar con el hawke airmax 30 8-32×50 que vale la mitad :( un saludo
Haré una version en español pues :)
@@BarcelonaAustinA35 se agradece la molestia, estaremos atentos.
Lo prometido es deuda! ua-cam.com/video/dT6F-NTUAA0/v-deo.html Es una traducción encima del video en ingles un poco chapuzilla pero espero que le sirva a mucha gente :-) Un saludo
Im watching from india love stripdown
Thanks mate
@@BarcelonaAustinA35 i think i like hw97 than tx200🙂 and otherwise im real fans(los galacticos)😏
How much
The kit? About 120€
PS at the end when you pour oil in the cocking lever , if you carry the gun muzzle down , that oil will run down the cylinder and when you cock the gun and have the muzzle facing up it will run on to the surface of cylinder and in to the transfer port making it diesel again DOH!
Hi thanks for your comment. I dont think i’ve put nearly as much for it to drip down into the transfer pot. Its still working pretty smoothly for now. But hopefully somebody else finds this useful too!
Che ottica usi
Grazie. Nikko stirling diamond 10-40X56
@@BarcelonaAustinA35 quanti jaule é la tua 977
16J. Non consiglio più potenza. ci sarà un rinculo e perderai la precisione. l'ottica soffre
@@BarcelonaAustinA35 ok grazie per il consiglio 👍io ho la versione in 7,5 joule
16J è perfetto per 50 metri in pellet .177
Far too much grease on that piston, should have watched a you tube video on how to do it first...
Thanks for your comment! Still working like a champ though
Scope is too long for the gun.
