ASSEMBLY
Numbers in parentheses refer to Fig. 6.
Note: Tighten all fasteners without special torques
specified to standard torques listed in
Section 300-0080, STANDARD BOLT AND NUT
TORQUE SPECIFICATIONS.
1. If removed, install new plug (7) in shaft end cover
(6). Be sure to install plug in the outlet side of shaft
end cover (6). The unplugged drain hole must be on
the inlet side of shaft end cover (6). Turn plug (7) in
until one thread of the hole is visible. Secure plug (7)
by staking around the hole with a punch.
2. If removed, install ring seals (8) into the bearing
bores in shaft end cover (6), bearing carriers (18 &
24) and end cover (28). The notch in the ring seal
must be visible. See Fig. 20.
3. If removed, press new bearings (9) into the bearing
bores of shaft end cover (6), bearing carriers (18 & 24)
and end cover (28) with an arbor press. See Fig. 22.
4. For each thrust plate (11) using pocket seals (10),
cut two pocket seals 9 mm (0.34 in) long from a new
seal strip. Coat with grease and insert seals into the
centre slots of thrust plates (11). See Fig. 23.
5. Place thrust plate (11) over bearings (9) in shaft
end cover (6), bearing carriers (18 & 24) and end
cover (28). With seals facing bearings, tap thrust
plate with a soft hammer to about 0.8 mm (0.031 in)
from machined surface. See Fig. 24.
6. For each thrust plate (11) using pocket seals (10),
cut four pocket seals 11 mm (0.44 in) long from a
new seal strip. Insert one pocket seal into each of the
outer slots in the thrust plates. Push each seal into
the thrust plate slot so that it touches bearing (9).
Tap thrust plate (11) down against the machined
surface with a soft hammer. Trim the exposed ends
of pocket seals (10) square and flush with thrust
plate (11) using a razor blade or sharp knife. See
Fig. 25.
7. With shaft end cover (6) clamped in a soft-jawed
vice, insert driveshaft and gear (12) into the shaft end
cover bore and push down until the gear is snug
