at oil temperature 20·C (68°F)
Measure the oil temperature.
If measured temperature is other than 20°C (68°F),
refer to the oil chart (page 14-73).
If the measured depth is other than the standa rd length,
disassemble the steering damper and start over.
The depth of the free piston wiJl change according to
