Assembling the motor and gearhead
Note
•
Forcibly assembling the gearhead and motor or allowing
a piece of metal or other foreign matter to enter the
gearhead will damage the motor pinion shaft or
gearhead gears, resulting in increased noise, shorter
service life or an unexpected accident. Exercise due
caution.
•
The motor cable cannot be assembled in the direction
facing the gearhead output shaft, because the cable will
be blocked by the gearhead case.
•
Do not let dust or other foreign matter adhere to the pilot
section of the gearhead or motor. Also, be careful not to
cause the O-ring to be pinched when the gearhead is
assembled with the motor. Dust adhesion or a pinched
O-ring may cause grease to leak from the gearhead.
The
GFS6G FR
has a lid to prevent grease from flowing out of the
gearhead. Remove this lid when assembling the motor.
Lid
Assemble the gearhead with the motor using their respective pilot sections as
guides. Do not press the motor pinion shaft strongly against the casing or
gears of the gearhead. Also confirm that no “gaps” exist between the motor
flange surface and the end face of the gearhead pilot section.
