    There's nothing really specific in the service manuals about procedure. YT's are about the simplest seal change you can do. I would advise, if you have a YDTL compressor that you not use a bellows seal, use the 6 spring style. I run about 2 psig at design evaporator temp on my seal oil pressure. As far as procedure, get you an OTC #522 puller and a couple of pieces of 1/4" all thread about 8" long and some nuts and washers, and a squirt bottle of oil (keep it soaked), and go to town. Make sure you push the rotating half all the way back against the shaft shoulder. If you've never done one before, it would be a good idea to get someone who has and let them show you (might save you some heartache in the long run).

    Yes there is some literature in regards to the recommended replacement if you want I will post it for YT & YK seals
    Arguing with your Boss is like wrestling with a pig in
    mud.
    After a while you realize that while you are getting
    dirty, the pig is actually enjoying it.

    It is not exactly cheating, I prefer to consider it
    creative problem solving.

    If you ask York, they will say you need to recover the charge, ole timers on the other hand will say bring it up to zero and hold it. Do they even sell the 6 spring anymore? I thought they did away with them.
    Go the extra mile, it's shorter than you think. UA in the Bay

    Yes 6 springs are available, however York recommends you use the Bellow style shaft seal. Although you can replace the seal by bringing up the pressure but then you wouldn't know how short you may be on charge or if you have another leak or the condition of the oil. If your changing a seal on a machine you preform service on and know the history then you probably can get away with short cuts but shaft seals are expensive.

    Zero it on R11, recover on R123. Leastways, that's how I do it.
