Figure 8-2: Packing / Mechanical Seal Assembly Overview
1. Loosen the slotted packing nut. (See Figure 8-1: “Pump Packing Seal Overview”
on page 131.)
2. Release the packing gland locking lever and set the lever roll pin on the housing
pin stop.
3. Loosen the split packing nut just enough to remove the split glands. If necessary,
soak the threads with penetrating oil and work the nut back and fourth to loosen.
If the front part of the gland is the split type, remove both halves.
4. Remove the old packing rings with a packing hook. The hook can be made from a
bent piece of stiff wire or small pointed rod. Another type of packing hook con-
sists of a corkscrew on the end of a flexible shaft.
5. Be sure to remove all shreds of old packing, and clean out the packing housing
as best as possible.
Note: Forced air can also be used to remove the packing. Use appropriate safety measures
if forced air is being used.
6. Remove all old packing, dirt and foreign matter from the bearing housing, espe-
cially under the packing gland.
