A tapered sleeve is available, at extra cost, for Q, QS and M
pumps from Viking Pump for seal installation on shaft. LS
size pump shaft is tapered and installation sleeve is not
available. Place tapered sleeve on shaft,
Refer to Figure 11.
THRUST BEARING ADJUSTMENT
Refer to Figure 13.
1.
Loosen two setscrews over each outer and inner end
caps.
2.
Turn inner end cap clockwise (viewed from shaft end)
until it projects slightly into opening on side of bracket
exposing approximately three threads.
3.
Turn outer end cap clockwise until rotor is tight against
head and rotor shaft cannot be turned.
4.
Make a reference mark on bracket end, opposite a notch
on outer end cap. Back off outer end cap required
number of notches as shown in Total End Clearance
Chart.
Refer to Figure 11.
Each notch represents .002”
end clearance.
5.
High viscosity liquids require additional end clearances.
The amount of extra end clearance depends on the
viscosity of the liquid pumped. For specific
recommendations contact factory.
6.
Tighten inner end cap with a spanner wrench. Tap
spanner wrench lightly but
DO NOT OVER-TIGHTEN
as
it will damage threads.
7.
Tighten set screws that hold inner and outer end caps to
prevent their turning in bracket.
8.
Check rotor to determine if it turns freely; if it does not,
add more end clearance.

Never touch sealing faces with anything except clean hands
or clean cloth. Minute particles can scratch the seal faces
and cause leakage.
Coat tapered sleeve and inside of the rotary member with a
generous quantity of SAE 30 non-detergent oil. Grease is
not recommended. Start rotary member on shaft and over
tapered sleeve.
Move rotary member so setscrews are directly below seal
access holes on left side of bracket (viewed from shaft end)
Refer to Figure 10.
Tighten all setscrews securely to shaft.
Flush sealing faces of both rotary member and seal seat
with oil and install seal seat and seat gasket over end of
shaft against machined bracket face. Assemble other seal
seat gasket, seal holder, seal holder plate, capscrews and
nuts and tighten securely. Remove tapered installation
sleeve.
Some Teflon seals are equipped with holding clips which
compress the seal springs. Remove holding clips to release
springs after seal is installed on shaft.
