9.3.4.3 Grease Replenishment for B-Axis Speed Reducer
(Refer to Fig. 9-7 “U-Arm Diagram”.)
1. Remove the hexagon socket head plug PT1/8 from the grease
exhaust port.
2. Install a grease zerk A-PT1/8 to the grease inlet. (The grease zerk is
delivered with the manipulator.)
3. Inject the grease through the grease inlet using a grease gun
– Grease type: Molywhite RE No. 00
–
Amount of grease: 190 cc
(380 cc for 1st supply)
– Air supply pressure of grease pump: 0.3 MPa or less
– Grease injection rate: 8 g/s or less
4. Move the B-Axis for a few minutes t
o discharge excess grease.
5. Wipe the discharged grease with a cloth, a
nd reinstall the plug. Before
installing the plug, apply Three Bond 1206C on the thread part of the
plug, then tighten the plug with a tightening torque of 5 N•m
(0.51 kgf•m).
6. Remove the grease zerk from the grease inlet, and reinstall the plug.
Before ins
talling the plug, apply Three Bond 1206C on the thread part
of the plug, then tighten the plug with a tightening torque of 5 N•m
(0.51 kgf•m).

for T-Axis Speed Reducer
(Refer to Fig. 9-7 “U-Arm Diagram”.)
1. Remove the hexagon socket head plug PT1/8 from the grease
exhaust port.
2. Install a grease zerk A-PT1/8 to the grease inlet. (The grease zerk is

– Grease type: Molywhite RE No. 00
–
Amount of grease: 180 cc
(360 cc for 1st supply)
– Air supply pressure of grease pump: 0.3 MPa or less
– Grease injection rate: 8 g/s or less
4. Move the T-Axis for a few minutes to discharge excess grease.
