The recommended oil lubricant has 68 cSt viscosity at
40 °C (104 °F) with temperature range from -5 to 80
°C (23 to 176 °F). Multiple manufacturers make this
type of oil with designation ISO VG 68 according to
ISO 3448 and DIN51524 part 2.
The maximum temperature that the
bearing can be exposed to is 105°C (220°F).
a) Align the motor coupling per the manufacturers
specifications and secure the pump to the base
plate.
b) Install a coupling guard over the exposed shafts
and coupling.
c) Once the pump has been bolted to the base
plate and leveled, remove the plug [6569] from
the top of the bearing frame unit [3011] and pour
in the recommended oil. The unit must be filled to
the center of the sight glass [3856] before
starting.
d) Do not overfill. The oil level should be checked
when the pump is stopped.
e) NOTE: Section 6.15 Steps e - g only apply to the
mechanically sealed version of the bearing
frame.
f) Tighten the mechanical seal’s (4) set screws to
the shaft with a 1/8 in. allen wrench.
g) Remove the (4) socket head cap screws from the
spacers / installation clips with a 9/64 in. allen
wrench.
h) Remove the (4) hex caps screws [6570.1] from
the spacers / installation clips and remove the
spacers from the seal with 5/16 in. wrench.
6.17 Bearing Frame Disassembly
If the bearing frame [3200] will not
be opened, the unit must remain horizontal to
prevent oil leakage through the bearing isolators.
Extremely strong magnets. The use
of non-magnetic tools and work surface is highly
recommended. The work area must be clean and
free of any ferrous particles.
a) Remove the metal plug below the sight glass to
drain the oil. Drain the oil into an oil pan and
replace the oil plug.
b) Remove the coupling guard if it is installed.
c) Remove the coupling and turn the motor aside to
allow room to pull back the bearing frame.
d) Remove the (2) hex caps screws [6570.1]
holding the bearing frame feet to the baseplate.
e) Remove the (4) hex caps screws [6570.1] on the
adapter.
f) Separate bearing frame [3200] and adapter
[1340] from pump end. Use jackscrews in the (2)
jackscrew holes if necessary.
g) Pull the bearing frame assembly straight back
from the adapter.
h) Remove the (3) hex caps screws [6570.11,
6570.12] to separate the foot from the adapter.
i) Secure the adapter [1340] to the work surface
with a C clamp.
The adapter o-ring should be replaced
before re-assembling onto the pump.
j)
Remove the outer magnet hex bolt [6570.1]. If
the outer magnet does not pull free, you will
need to use our outer magnet removal kit.
k) Attach the MAO Puller Bracket with (2) 3/8in.-16
socket head cap screws.
l) Insert the jackbolt into the tapped center hole
and tighten until the outer magnet loosens.
m) Pull the outer magnet assembly out of the
adapter and set aside.
n) Install the (4) spacers / installation clips onto the
mechanical seal at this time. The spacers are
used to prevent damage to the internal
components when not bolted into the bearing
frame assembly.
o) Once spacers are in place, remove the 4 screws
securing the mechanical seal to the adapter.
p) Remove the (3) hex caps screws [6570.1]
securing the adapter to the bearing frame.
q) Slide the bearing frame off of the adapter with
the seal still attached to the shaft.
r) Loosen the (4) mounting setscrews holding the
seal onto the shaft and gently slide the
mechanical seal off of the shaft.
NOTE: Replace the inner and outer o-rings on
the mechanical seal before re-assembly.
s) If the bearing frame will not be opened, set it
aside.
