and punch (see FIGURE 16, page 16).
Exercise care not to damage the
headplate bearing bores when remov-
ing bearings.

The grease seals (15) can now be driven out of the
drive headplate with hammer and punch (see
FIGURE 16, page 16). Discard the seals as they
will not be reused. Replace grease seals each
time the headplate is removed.
Seals and bearings should be re-
placed during overhaul as a matter of
service policy.

bly following the same procedure.
18. Remove mounting foot (17) from the gear head-
plate by removing 4 capscrews (16).
19. Remove the cap screws (21) securing the gear
headplate to the impeller case. Located near each
dowel pin on the headplate is a threaded hole. In-
sert a 3/8--16 UNC capscrew into each of the
threaded holes. Tighten the screws evenly until
the headplate separates from the impeller case.
20. Remove the two gear end bearings (14) from the
gear headplate (18) as done in step 12.
