Assembly video: • Weihrauch HW97k Assemb... Strip down instruction for Weihrauch HW77 and HW97 air rifles. Applies also to Beeman 77 and 97 rifles. But be careful, they have a much stronger spring in it.
Earlier today I stripped my HW 77 down and did TNT and clean up! Don't think it has ever been stripped down before? I got it second hand and I see where some previous owner had tried to tighten stock screws with standard screwdriver instead of a Gunsmith set of tools? Thank you! WOW! Semper Fi!
Very few steps are different. The trigger housing must be rotated out of a little notch. Very easy to do if you take an allen key and poke out the four small blocks which are located on the left and right side of the trigger housing after that place cylinder on a small rubber object and rotate counter clockwise. The trigger housing should come right out.
good filming angle , all was so clear, was afraid when you were unscrewing the main spring casing, thought the spring may kick out .. but went smooth. good.
Very good video. I've just bought a second hand HW77k, around 1984 vintage, and will be stripping it to have the action reblued. Might as well replace a couple of parts, too. I'll also be using your greasing video to help me with that.
Thank you for the video... I used it to see how to disassemble and reassemble my HW77K... the orientation of the "anti-bear trap assembly" got me confused because the piece held by the spring got turned around after I removed it... so I had to re-watch your video... I saw another video where the gunsmith had already removed the anti-bear trap since it really serves no useful purpose, as long as you know to always hold the cocking lever or barrel when loading a pellet... apparently, when you remove it, you can now de-cock the rifle, which is nice to be able to do... I left mine on for now, but may end up removing it later.
I noticed there’s no top hat in the mainspring, just a spring guide. Are all 77s this way? Just tuned two 99s’s, and they both had top hats🫣 Maybe its still in the piston. This is often the case…With a few washers too. Nice job🤗
I just thought id like to add, when putting the rifle back together, when you screw on the end piece where the trigger unit goes make sure it is lined up perfectly before screwing in the trigger guard / stock screw. mine was misaligned by about 1mm but i screwed in said bolt thinking it would just tighten and line everything in, but no. instead i cross threaded virtually all the threads and f**ked my bolt. just so you know =)
I realize this is an old post, but I just installed a Maccari Air Rifle Headquarters kit in my HW77K today... to get the end cap completely tight, I used the handle from a crescent wrench that I put in a vise (covered with a rag to protect the end cap slot), inserted it in the end cap slot and forced the end cap completely closed, which also aligns the scope grooves as well as the stock lug screw.
@@craigbrowne8563 I've used several of Jim's kits and lubes over the years... the first place I go to whenever I need something spring-gun related... I have a couple of his DIY stocks that he use to make many years ago.
@@airmojo Thanks for the fast reply.. I just got one of his hornet full power kits for my HW 97. It came with 1 tub of grease. Is this just to put on the spring ? Or is this molly paste for everything? thanks
@@craigbrowne8563 If it's real dark black, then it is the black tar for the outer part of the spring... Moly is more of a dark gray that you can apply lightly to metal friction points, and the outer side of the piston seal. If you have any questions, just email him, or you can probably call him.
So, @ the 4:30 mark when you took the wrench and covered it w/ a towel and whacked it w/ a screwdriver & started loosening that part, this is when you need the compressor w/ a Beeman? Can one hold it straight up and down on the floor and control the spring that way? Thx.
Very nice video. But I stuck at about 4:25. I'm totally not able to unscrew trigger housing (hopefully I use correct name for the thing that needs to be unscrewed to get spring out). You used a few pokes of screwdriver but for me it looks like it is glued. Any ideas?
Yes, some threads of the trigger housing can be rusted due to the blueing process. Get a hot air pistol with 500°C and heat up the end piece till you see smoke rising. Then grab a fitting spanner slide it into the trigger slot and give it a good hit with a hammer. That will loosen the threads.
2lbsTrigrPull Thanks a lot for your quick reply. Smoke rising? Uh. I'm afraid I'll damage parts made of plastic that are quite close to the thread. I found some people suggesting to soak it in diesel or some oil. What do you think about such a advice?
Tomáš Hubálek Will not work. The end piece can be very stubborn to remove. Clamp the cylinder in a vice so it can't rotate (with the cocking arm rested onto one clamp of the vice but cushion it so it doesn't scratch up) heat up the end piece with the a torch or hot air pistol and then go to work with a spanner and hammer. I already opened several HWs with this method and if you are careful the nylon spring guide will not get damaged. But try it with soaking oil first and see what happens. Maybe it will work.
Tomáš Hubálek Here are pictures of the last factory fresh HW97k I opened: www.airgun-austria.com/t1074-s60-gewinde_laesst_sich_nicht_oeffnen_bei_der_hw97.html I advise everyone who buys a new HW97 to open, clean and relube it. Otherwise it will get rusty very fast...
Thank you so much for you answer! Have you tried the accessory VORTEK ProGuide 2 If you have tried it, do you know how many Joules the Feather will give a Hw50s with .22 caliber? Thank you very much!
der hintere Teil wo der Abzug drinnen sitzt ist doch inzwischen nur noch schwer abzubekommen bei einer neuen Waffe, da die Sicherungsmittel für das Gewinde verwenden, hast Du das auch schon festgestellt? Dass Du nicht mal einen Schraubstock brauchst ist der Hammer
the spring i took out of the beeman rs1 is 11.5 inch long, 44 coils, 15 mm out dia, inner 10 mm, wire thickness is a darn 2 mm :-)...I will contact Weihrauch like you said..the spring u have look thick 380 ms
first of all thanks for this video, can you please tell me what can be the cause HW 77 in order to be fired the safety catch must be pressed continuously in order to fire .
I can never understand why there’s none speaking stripping guides seems daft. Each to their own I suppose. Good video though nice clear view of what’s going on.
hopefully you still read your comments; it's my first time disassembling it, and i can't get this part done 4:22 i use the same tools and hit the same way, even harder, it won't move at all, i'm even afraid to damage it knowing how hard i've been hitting. Was it the same for you? cheers
I bought an HW77 .22 with a red dot sort of scope £60.. I know absolutely nothing about guns.. So i was just wondering if that was a good price? Ps nice video :)
kann bestätigen dass die Qualität nachlässt, neue HW 97 KT, nach 100 Schuß Laufgewicht lose. Reparatur dauerte fast einen Monat, danach Kratzer im Schaft:-(
i have just purchased a 2nd hand one of these today.Its an 80's (west german) model.I will probably strip it down so this is very useful for me.Does it have a breech seal too? If so,how do you remove it?
Wow I can't believe you guys can find these things used for sale. I am waiting for my HW77K to arrive and I can safely say I will NEVER part with it. I am 43 and haven't even seen one of these things in person before. Mine cost $600+14% taxes + shipping Canadian/US $ same these days plus the scope. It seems as though you guy by them cheap over there." I wish" man I'd own every Weihrauch underlever model made. I still will but it's going to cost me lots more.
