    Have a B6s Cat breaker in the shop and was hoping someone would be able to pull up a charge spec for the nitrogen. Unfortunately the serial number tag is damaged and all I can possibly make out is that the prefix starts with an "H" maybe.

    Going out on a limb I'd guess its probably going to be in the ballpark of 220 PSI but I'd rather have the actual spec.

    Probably just a "B6" HA6.

    I wasn't too far off on my guess.

    Thank you very much.

    Well its not looking good for this one. It still had the majority of its nitrogen charge in the top. Everything else looked good so I took it out to the test slab and fired it for a while. Wouldn't ya know it, its leaking oil like a sieve. Took it all apart and there's some pretty deep damage to the piston and cylinder - too deep to polish out unfortunately.
