    If you've tackled the Owner Service on the JJ-CCR, you know how frustrating it can be sorting through the 53 unlabeled orings in the main kit, not to mention the 11 more in the DSV kit! Although there are a couple of guides out there (with thanks to Kieren Hatton), there is room for a more compact way of sorting your o-rings in preparation for service.

    With the generous assistance of @taimen , I have created a printable guide that splits the o-rings into logical groups. The attached PDF is arranged for printing with a 100mm square on each page for calibration, so that you can divide your o-rings before you even disassemble the breather, and perhaps repackage your kit into logical sub-kits. There is one added o-ring for the stock OPV which is on the Canister page, which is not in the standard factory kit.

    I have also had the complete set of all 64 JJ-CCR orings (+ 2 OPV o-rings) produced through a combination of custom manufacture and McMaster Carr stock, in Duro 75 Nitrile. It is available for purchase at a modest (20%) discount off the cost of OEM o-rings from the U.S. distributor, not to mention factory cost from Denmark. More important, it is available immediately. Note: the factory points out that aftermarket kits are not authorized by JJ. Therefore, these o-rings should be used at your own risk. Contact me if you have an interest.

    Enjoy the sorting templates attached below! Consider printing the pages and cutting the guides out. Slip them in the factory kit bags and your next service might be a bit easier.

    Great stuff.

    A friends also gave me this one, very nice diagrams and if you print it to scale all O-rings are actual 1:1 size.
