chain and lubricate with good quality
waterproof light grease.

motion (backlash) in the steering gear and
correct if necessary. Lost motion at the wheel

should not exceed 2% of the total wheel
movement from lock to lock. This does not
apply to the Linear or Hydraulic drive systems
which are normally directly coupled to the
rudder stock.

from leaks and trapped air. Bleed when
necessary to remove air from the system.
