2012 Primary/Secondary Seal Head Insert Removal

gland and a seat, but is removed by pushing with the special Seal
Installation/Removal tool, part number (See Figure 60).

The gland contains the secondary seal head insert, if present,
which is held in the primary by an O-ring. Make sure to hold the
insert or use a soft cloth to catch it to prevent it from dropping
when removed.
NOTE:
To prevent damage to the seal face, do not place seal
face down on any surface during maintenance.
To install a new primary or secondary insert, lubricate all o-rings.
Use the fit of the o-ring at the top of the head bore to verify that
the inserts are correctly aligned in the bore. Make sure to align
the anti-rotation pin with the hole in the bottom of the head bore.
Insert the stainless steel gland into the head, using the
Seal Installation/Removal Tool with an even distribution of force.
Then install the secondary insert into the gland. Finally, align the
lugs on the stationary seal face with the spaces between the lugs
on the gland, and insert until it meets the gland.
