Assemble the holder.
Once the housing has been fitted, move
the housing along the spline shaft
approximately 5 mm a couple of times
so that the Y-shaped packing will be
smoothed.
* Be sure to push the housing fully until
there is no gap. Tighten the housing.
Check that the housing rotates smoothly,
moving the housing left to right a couple
of times
Check the spline shaft for sliding.
1. Sliding torque specifications:
1.47 N or less
• Tension gauge
To avoid damaging the Y-shaped packing, use tweezers whose end
is round and make its edges round before fitting the Y-shaped
packing into the housing.
