9.3 Grease Exchange Procedures
 Grease Replenishment
(Refer to Fig. 9-4 "U-Axis Speed Reducer".)
Replenish grease following the procedures below.
1. Remove the hexagon socket head plugs PT1/8 on the Uo grease
exhaust ports and the Ui grease inlets.
If grease is added without removing the hexagon socket
head plugs PT1/8, the internal pressure will increase and
NOTE
may cause a damage.
Never fail to remove the hexagon socket head plugs PT1/8
before the grease injection.
2. Install grease zerks A-PT1/8 on the Ui grease inlets, then inject
grease.
Grease Type: Molywhite RE No.00
Amount of Grease: 100 g (200 g for 1st supply)
Air Supply Pressure of Grease Pump: 0.3 MPa or less
Grease Injection Rate: 8 g or less
3. Move the U-axis for a few minutes to discharge excess grease.
4. Reinstall the hexagon socket head plugs PT1/8 on the Ui grease inlets
and the Uo grease exhaust ports. Apply ThreeBond 1206C to the
thread parts. (Refer to Table 10-1 "Spare Parts for the MOTOMAN-
MFL15D-875 (YR-MFL015D-A00)".)
 Grease Exchange
(Refer to Fig. 9-4.)
1. Remove the hexagon socket head plugs PT1/8 on the Uo grease
exhaust ports and the Ui grease inlets.
If grease is added without removing the hexagon socket
head plugs PT1/8, the internal pressure will increase and
NOTE
may cause a damage.
Never fail to remove the hexagon socket head plugs PT1/8
before the grease injection.
2. Install grease zerks A-PT1/8 on the Ui grease inlets, then inject
grease.
Grease Type: Molywhite RE No.00
Amount of Grease: Approx. 400 g
Air Supply Pressure of Grease Pump: 0.3 MPa or less
Grease Injection Rate: 8 g or less
3. The grease exchange is complete when the old grease is drained off
and the new grease appears in the Uo grease exhaust ports. (The new
grease can be distinguished from the old grease by color.)
4. Move the U-axis for a few minutes to discharge excess grease.
5. Wipe off the exhausted grease with a cloth, and reinstall the hexagon
socket head plugs PT1/8 on the Ui grease inlets and the Uo grease
exhaust ports. Apply ThreeBond 1206C to the thread parts.
