Remove the seal cover and gland half casing assembly

1. Remove the gland casing and seal cover assembly by supporting the casing assembly with

a hoist hook through the lifting lug.

Figure 82: Removal of seal cover and half gland assembly

2. Remove the pedestal to casing (427L) and (3701) hardware.
3. Hoist the casing assembly to the ground so that the seal cover or stuffing box cover can be

removed.

Figure 83: Seal cover removal

4. Remove the seal cover retention hex head cap screws (388A) and clipped washers (354A).
5. Remove the seal cover (184) from the gland half casing (100D). Use a short pry bar to

gently and evenly facilitate disassembly if necessary.

6. Remove the seal cover o-ring (496R, XHD).

Optional disassembly of gland half casing, gland liner, and seal cover -
Rubber-Lined

NOTICE: When there is no expeller assembly supplied, the Gland casing assembly can be
removed and rebuilt as an assembly.

The gland half casing (100D), volute liner (600T), seal cover (184), and/or split stuffing box
assembly (159), can be removed as an entire assembly
1. Once the impeller is removed from the shaft, support the entire gland casing assembly with

a strap, located thru the appropriate gland half casing hoisting location.

2. Loosen and remove the casing to pedestal bolts (370Y) and nuts from the taper alignment

studs (427L).
