Checking Friction In The Panning Direction (Hdvf-El75) - Sony HDVF-EL70 Service Manual

1-9-3. Checking Friction in the Panning Direction (HDVF-EL75)

The number of pan shaft spacers varies depending on unit. When replacing pan shaft spacers, install the
same number of pan shaft spacers as the number before the replacement.
After the pan shaft spacers have been replaced, assemble the main unit according to the figure below and
check the friction in the panning direction.
Apply locking compound
(ThreeBond TB-1401B or
equivalent) to the end of
the screw.
Grease the side surface
of the pan shaft.
Checking and adjusting friction in the panning direction
1. Attach the main unit to the camera.
2. Push the edge of the tilt table and check that the friction is the typical value.
Typical value: 20.Nm
3. If the friction is not the typical value, increase or decrease the number of pan shaft spacers to make
the friction equal to the typical value.
When the friction is lower than the typical value, increase the number of pan shaft spacers.
When the friction is higher than the typical value, decrease the number of pan shaft spacers.
