2. Remove the hexagon socket head plug of the grease inlet and install
the grease zerk A-PT1/8. Inject grease through the grease inlet using
a grease gun.
(The grease zerk is delivered with the manipulator.)
– Grease type:
Alvania EP Grease 2
– Amount of grease:
approx. 60 cc
– Air supply pressure of grease pump: 0.3 MPa or less
– Grease injection rate:
8 g/s or less
3. Reinstall the plug into the exhaust port. Before installing the plug,
apply Three Bond 1206C on the thread part of the plug. Then tighten
the plug with a tightening torque of 4.9 N•m (0.5 kgf•m).
4. Remove the grease zerk from the grease inlet, and 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 4.9 N•m
(0.5 kgf•m).
