Assembly
1. Install new gland seal 14 Figure 10-32 using the special
and installation tool as follows:
NOTE: The size (diameter) and position of pins is
determined by the diameter and radial width of the
gland seal being installed.
The pins are screwed into threaded holes in the
tool body, the spacing of the holes is designed to fit
small and large diameter gland deals.
a. Open the tool Figure 10-33 and insert the new gland
seal. The seal must be installed behind the two front
pins but in front of the rear pin as shown.
