    Hw99 cocking lever replacement

    Hello everyone

    Any ideas how to remove the pin that attaches the cocking arm to the lever? Looks like the pin is pressed over itself slightly (mushroomed for want of a better word) almost like a rivet concept.

    Need to replace the cocking lever so would need to re use the pin.

    I'm sure you used to be able to buy a removable bolt to replace his pin. Are they still available from anywhere?

    Thank you

    I have never had the need to remove, so would also be interested in knowing the correct method.

    I don't know if V-Mach still so the removable pin? You could have a look on either the V-Mach or Blackpool Air Rifles site to see?

    I seem to remember someone else also offering this style of pin, but can't for the life of me remember who it may have been. Someone else will chip in soon.....

    P.S. Just had a quick look on the BAR site. The V-Mach items are shown as being out of stock currently, priced at £9.95. Maybe worth a call to find out when next available?

    To knock out pins that are peened over you use a punch that has a head size of the dimple depression in the centre of the pin. When you tap it with a hammer the peened edges fold up to allow the pin to be knocked out. When replacing push the pin back in the way it came out and use a punch the full diameter of the pin to peen back the edge of the pin. You will need to support the other side of the pin on another flat punch. Better with two people doing this (use the domestic help). Can also be squashed back in a vice if you are careful with some packing pieces or even small ball bearings.

    One side of the rivet will look slightly larger than the other side. Use the punch on the smaller side. I place the breech on a block of wood with a hole drilled in it.
    Don't be shy, it takes a fair bit of whack to start the pin moving. Use a good punch as described above and preferably a reasonably large ball pein or lump hammer. Once the rivet starts to move it becomes easier so use less effort.
    I believe the punch size you need is 4mm.
    I use stainless roll pins to replace the rivet. Cheap to buy a pack of 10.

    As Benelli says, a very easy job.

    Used to use a clamp like this for rivets https://www.directchannel.uk.com/flange-clamps just modified it to push the pin out , drilled the bolt and inserted a hardened pin and a hole in the bottom to let the pin go through.

    Or you could just buy a new Diana and the pin will just fall out

    Yes I said it.

    Once you get the pin out, it's better to replace it with one of these to make the whole procedure easier in the future:

    Vtech also do one.

    As Baz says. Would just add that you can stick a ball bearing each side with grease or even cellotape then crush in the vice or clamp.
    The tape is good if hitting with a hammer.

    rg627,

    +1 on Shauny's take down pin.

    The VMach pin uses a very small screw to secure, and there have been reports that these are sometimes very difficult to remove if the user was 'enthusiastic' when installing.

    Shauny's pins are 300 series stainless, and use a single circlip to secure and I highly recommended them.

    (My three (3) HW break barrel's all have Shauny pins.)

    Have fun & a good Sunday

    Best regards

    Russ
