    I'm trying to strip the Hw95. However at the point where you press down and turn the rear end to release the spring I run into trouble. It just seems very difficult to do this. I can see it turns a little, but the last bit is very hard to do. Before I try more, I just wonder, am I in for a nasty surprise when the spring releases? Rememeber this is a HW95 exported for Norway. No restrictions.

    Our sub 12’s it pops out with no surprises. Yours however I would suggest a spring compressor maybe as it’s a lot more powerful.

    If you’re really careful place an old piston seal on the floor and with the 95 up right keep all your weight on it as you turn the block on the seal and slowly lift.

    Sometimes the end block can be quite sticky. It may help to have another pair of hands to gently lever the little block out of the notch with a screwdriver.
    As always be very careful though the weight of a full grown male should be able to retain any spring force. The 95 even in FAC form should only run around 16ftlbs.
    If in doubt use a spring compressor.

    Thanks guys. Ok. I'm sure it will release with the help of a screwdriver in the notch. I just was a little worried..
    And yes.. putting it back again.:eek: What is this compressor and where do I get it?

    Ok, new problem. Looking at the piston seal there's a scar on the surface. see picture. This gun only shot 300 pellets. What's your advice?

    In the bin with that.
    Tis (swear word) as they say here :)

    Deburr all the cocking slots before installing a new one.
    Lube sparingly and ensure none gets forward of the piston seal on reassembly

    Thanks rob. Could you elaborate a little which cocking slots you mean? :rolleyes:

    Yep, that has had it! As you push the piston and seal in there are holes it has to get by. If any of these have sharp edges they can carve bits out of the seal

    Thanks all. I will bring the piston to the Weirhauch dealer and claim a warranty repair.
    Nick, I added one more private question..

    Yup that seal has had it. Keep it though as it’s useful for getting the trigger/back block off.

    ..I wonder how many air rifles out there suffer from these and related faults. Just by coincident I discovered the bad seal (in a new gun!) because I decided to equippe it with a tuning kit. :confused:

    Far too common is probably the reality.
    Poor QC and shoddy assembly.
    I replace seal on any gun new to me as a matter of course.

    And of course here in the UK we not only have the pleasure of Weihrauch’s rushed quality control but then also HC strip it to dick about.

    Jesus they pay no attention or care and just shove these seals in like a trained monkey! :facepalm:

    I always slide the piston/seal very carefully down past the cocking slot and give the seal a little push (sideways/inwards) with a small paint brush handle to ensure the edge doesn't snag on that last bit of the slot.

    They're okay once they've had the burrs cleaned up on the edges anyway. :up:

    Funny you should mention the old seal on the floor Mikey, I use a round pencil eraser :D, to turn the trigger block on my 80 I use the handle of an adjustable spanner wedged between a piece of 3mm rubber pad that I wrap around it, it fits in the trigger slot snugly and leaves no marks - it was tight as hell from the factory! - when it first gave way I thought I'd snapped the spanner!
