Glass surfaces may be cleaned using a more
aggressive solvent such as acetone, if
necessary.
SHOCK AND BURN HAZARD: Only
clean inside the bath when equipment is de-
energized and unplugged from the mains power
supply. Allow adequate time for heating coils to
completely cool before cleaning.
6.3 Inner Ball Bearing Replacement
K19201 has two ball bearing assemblies. The
test bearing is replaced after every test, since
grease sample must be packed into it, as
described in Section 5.2. The secondary ball
bearing does not need to be replaced after every
test. The secondary ball bearing is located next
to the motor (see Section 4.1, Item 9). The
secondary ball bearing is recommended to be
replaced after 1 - 2 years of operation. To replace
the secondary ball bearing:
1. Remove the test bearing assembly as per
Section 5.2 by removing the 5 thumbscrews.
2. Using the supplied tool to remove the
secondary bearing assembly (part numbers
414-104-3108 and 463-964-001), unscrew
the four screws that hold the secondary
bearing assembly in place. The screws are
located on the side of the assembly that faces
the motor shaft.
3.
Once the screws are removed, carefully
remove the secondary ball bearing assembly
out of the instrument.
4.
Disassemble the bearing assembly. Figure
12 shows each component of the assembly.
Figure 12. Secondary Ball Bearing Assembly
5. Replace the secondary ball bearing with a
new, unused secondary bearing. Do not use
a test bearing in this assembly.
6. Replace the O-ring of the secondary bearing
assembly with a new, unused O-ring.
7. Reassemble the secondary bearing
assembly.
8. Insert the secondary bearing assembly into
the instrument, in the same position and
orientation in which it was removed.
9. Screw the four screws into the secondary
bearing assembly using the supplied tool to
hold the assembly in place.
7 Calibration
7.1 Nozzle Position Calibration
The angle of the water jet can be adjusted and
locked in place so that it strikes the same position
of the test bearing for each test. The K19201-
03006 special gauge is used to adjust the angle
of the water jet, which is purchased separately
from the instrument. This proper position of the
water jet is shown in Figure 13, and the procedure
to adjust this position is described below.
Figure 13. Calibration of Water Jet Position
1. Attach the test bearing assembly to the test
position using the thumbscrews.
2. Place the K19201-03006 gauge on the
bearing assembly. The gauge should rest
with the two upper thumb screws of the
bearing assembly inside the two outer
grooves of the gauge tool. See Figure 13 for
reference.
3. Turn the spray
switch to the “Water Spray”
position. Water will then begin to spray out of
the nozzle.
4. The water jet should strike the bearing
assembly directly in the corner of the middle
groove of the gauge tool. This is shown in
Figure 13.
