Autoquip SR4 MANUAL TURNTABLE - Manual (Page 22)

22
Turntable is making a popping
noise. • One or more roller tubes are misaligned with
respect to the center pin. Each tube should be
perpendicular to the center pin, or the platform
will roll across the roller instead of rolling over
it. Perpendicularity can be checked using a
large square. Call the factory for base
replacement.
PROBLEM POSSIBLE CAUSE AND SOLUTION
Turntable is difficult to rotate • There may be roller damage. Check the
turntable base rollers for proper alignment and
possible bearing damage. Replace as
necessary.
• The load is not evenly distributed on the
platform. Make sure that the center of gravity
of the load is within 10” of the center of the
turntable.
• One or more tubes are not sitting vertically on
the base plate. Make sure that each roller
tube is perpendicular to the base plate (it could

b e e n b e n t s l i g h t l y d u r i n g
shipping/handling). Call the factory for base
replacement.
• The thrust washers are not installed properly.
See Figure 5 in the Installation Section to
ensure that the center pin thrust washers have
been installed properly. Missing washers will
cause the platform to “dish” in the center when
bolted in place.
• The center pin-retaining bolt has been over
tightened. The retaining bolt should be backed
off and retightened using no more than 80 ft.
lbs of torque.
• If the turntable was provided with detents, the
detent bar may be set too tight. There is an
adjustment screw to lessen the stopping
pressure against the detent pins.
