Packing Gland Adjustment

For The Traditional Stuffing Box / Packing gland:

If you have a more traditional stuffing box / packing gland, you'll see two very large brass nuts around the shaft. The packing material resembles clothe with a waxy feel to it. It's packed around the shaft. As the collar/nut is tightened, it compresses the packing material more snugly to prevent leaking. But a packing gland *does* need to leak. The leaking serves to cool it and also proves that it isn't TOO tight. If it's too tight, it will overheat, and not get any water to help cool it. This will cause premature failure of the packing gland which will then need to be replaced (and constant tightening).

The 2nd collar/nut is really just to lock against the first so that, once set to the appropriate amount of compression on the gland, it wont move.

Adjust the gland so that you're seeing 1 drip of water ever 15 seconds while the shaft is NOT engaged / turning. Use the lock-nut to lock it in position once you've found that rate and re-verify that you're still getting 1 drip about every 15 seconds (as it tends to turn the packing gland adjustment when you try to tighten the lock nut).
