SCHEDULED MAINTENANCE 2 - 8
Steering mechanism
Verify the condition of the ball joints and check for excessive
play in the pivots of the steering system. For alignment, refer to
the "
Chassis and steering " section.
Assembly
The chassis of the SNOW HAWK is different in that most of the
assembly is done by bolting components rather than welding
them. Therefore, bolts must be checked and tightened as need
be. When doing this, refer to the table entitled "
TORQUES " at
the end of this section.
2.9. ELECTRICAL SYSTEM
Spark plug
Check the general condition of the plug, the colour of its
electrodes, carbon deposits, plug gap and possible damages to
the gasket
A NGK BR9ES spark plug is recommended.
Check the spark plug gap. The suggested gap is 0.45 mm
(0.018").
When tightening the spark plug, the torque must be between 25
and 30 N-m (18 and 21.5 lbf-ft; 2.5 and 3.0 kg-m).
