Drain the oil from the drum support housing into a
suitable container. The capacity of the drum support
housing is 1.9 liters (0.5 U.S. gal).
Remove two bolts (1), and remove vibratory motor (2)
from the vibratory gear box. When installing, apply 9S-
3263 Thread Lock on the threads of two bolts (1).
Remove 12 bolts (3), and remove cover (4) and the O-
ring seal from the vibratory gearbox. Check the O-ring
seal for damage or wear and replace if necessary.
When installing, apply 9S-3263 Thread Lock on the
threads of 12 bolts (3).
Remove coupling (5) from shaft assembly (6).
Loosen the lock nut, and turn vibratory sensor (7)
counterclockwise three turns. Remove shaft assembly
(6) from the drum support housing.
Apply 6V-4876 Molykote Paste Lubricant on the
splines at both ends of shaft assembly (6) before
After installing shaft assembly, measure the
length of shaft assembly (6) and adjust as
required. For the proper procedure refer to the
topic "Drum Assembly" in the Specifications
module for the vibration system, Form No.
When the length of the shaft assembly is correct,
make sure the sprocket on the shaft assembly is
centered beneath vibratory sensor (7). When the
sprocket is centered, turn vibratory sensor (7) in
(clockwise) until it touches the tips of the
sprocket teeth. Then back the vibratory sensor
out approximately one turn. This will provide a
clearance (gap) of 1.6 mm (0.06 in) between the
sprocket teeth and the vibratory sensor.
