Step 2
• When inserting the input gear, release the
tapped hole for injecting/draining grease so that
the internal pressure will not rise. After inserting
the input gear, close the tapped hole for
injecting/draining grease.
(For a hexagon socket head cap plug, use seal
tape)
• When inserting the motor, if the lubricant leaks
from the reduction gear into the motor chamber
through the oil seals, remove the input gear and
wipe off the leaking lubricant with a clean cloth.
If you fail to perform step 2, the internal pressure of the reduction gear increases while inserting the
motor. If the reduction gear is operated under this condition and the temperature of the reduction
gear increases, the internal pressure of the reduction gear exceeds the allowable pressure range of
the oil seals, which could cause the leakage of the lubricant.
