Re–Greasing the Harmonic Drive Bearing, Section 11.3.3
11.3.1 Replacing the Cam Rollers Recommended Frequency:
•
For ambient temperature systems—every 2 years of regular use, or as required.
•
For high temperature systems—every year of regular use, or as required.
Both the left and right side covers on the ambient temperature pump cylinder have vertical lines
that are numbered 0 through 10. When the pump is operating, the relative position of the piston
can be monitored by watching the cam roller, which is attached to the ball nut, move from one
line to the next.
There is a cam roller on each side of the pump cylinder. Different cam rollers are used for high
temperature and ambient temperature systems. These components, while simple, perform an
important job in the pump cylinder. But their internal lubrication can dry out over time, especially
on the high temperature pump systems. This procedure explains how to confirm the cam rollers are
working properly, are lubricated correctly and, if necessary, how to replace them. Refer to Figure
11-4 and Figure 11-5. The cam roller and stand–off shown in Figure 11-5 is shown magnified and
with the roller slightly unscrewed for clarity.
