piston rod and insert two bearings before retaining
it with contraction stop ring (See Fig.29). (When
using single shield type bearing, it should be
installed with its seal surface facing outward.)
Install USH packing to piston. (See Fig.30.)
(Push it in with your finger after coating with oil.)
Place the piston over the bearing and push the
assembly into vibrator case, before retaining it
with the expansion stop ring which had been
installed earlier (See Fig.31).
When using commercially available bearing,
use molybdenum extreme pressure type
grease to pack.
Apply grease to the area of piston rod where
bearing is inserted.
Make certain that piston has no scar or scratch.
Use care not to damage piston.
Install packing in proper direction.
To install the piston, either push it in with hand
or lightly tap on it with plastic hammer.
When installing the expansion stop ring, use
bent nose type plier and make sure that it has
seated properly in the groove.
After installation, make sure that the piston
rotates smoothly.
