and bar (see figure 7-3). Do not attempt to bottom-out seal, press in only until it is flush with the face of the
recess. Wipe off surplus sealant.
h. Grip the shaft end cover (13) in a vise with the mounting face down. Cut 2 pocket seals (14) 7/32" long from
the pocket seal strip. Grease these pocket seals well and insert them into the middle slots on the reverse side
of the thrust plate (11).
i. With the pocket seals (14) facing down, place the thrust plate (11) over the bearings (16) in the shaft end cover
(13). Tap thrust plate with a soft hammer to about 1/32" from the machined surface.
j. Cut 4 pocket seals (14) approximately 1/4" long from the pocket seal strip. Insert one pocket seal into each of
the slots in the thrust plate (11). Push each pocket seal all the way in so that it touches the roller bearings. Tap
the thrust plate down firmly against the machined surface with a soft hammer. Use a sharp razor blade to trim
exposed end of the pocket seal square and flush with the thrust plate.
k. Insert the splined end of the drive shaft (12) into the special steel sleeve (see figure 7-3). Lightly grease the
drive shaft and sleeve. Insert the integral gear and drive shaft (12) with sleeve into the shaft end cover (13)
with a twisting motion. Be careful not to damage the double lip seal (20). Push down carefully until the gear
rests against the thrust plate. Remove the steel sleeve. Insert the driven gear.
l. Grease the new gasket seals (15) and insert them into the grooves in both sides of all gear housings (6 and 10).
m. Slide the first section gear housing (10) over the gears and tap it with a soft hammer until it rests lightly against
the shaft end cover (13). Be careful not to pinch the gasket seal (15). Squirt oil over the gears to provide initial
lubrication when pump is started.
n. With the thrust plates (5 and 11) mounted on the bearing carrier (9) (as in steps h, i, and j), position it on the
gear housing (10) so that the roller bearings receive the journals of the drive and driven gears (12). Make sure
that the drain port in the bearing carrier is on the suction or inlet side. Make sure that the index marks are
properly aligned.
o. Insert the connecting shaft (8) in the spline of the drive gear (7).
p. Insert the drive and driven gears (7) of the second section in their respective bearings. Make certain gears are
in contact with thrust plate face.
q. Slide the second section gear housing (6) over the gears and tap it tight against the bearing carrier (9) with a
soft hammer. Be careful not to pinch the gasket seal (15). Squirt oil over the gears to provide initial lubrication
when pump is started.
r. Place the port end cover (4) over the gear journals and tap lightly against the gear housing (6). Be careful not to
pinch the gasket seal (15).
