CA TIMING BELT TENSION ADJUSTMENT
1. After turning the crankshaft a 1/4 turn anti-clockwise, turn
it clockwise to the position where the timing marks are
aligned.
2. Loosen the fixing bolt of the tensioner pulley and using the
special tool and a torque wrench, apply tension to the timing
belt; then tighten the fixing bolt at the specified torque.
Standard Value:
2.5 – 4.0 Nm {timing belt tension torque (reference
value)}
Caution
When tightening the fixing bolt, ensure that the
tensioner pulley shaft doesn't rotate with the bolt.
3. Take out the 2 mm Allen wrench from the auto tensioner.
At this time, check to be sure that 2 mm Allen wrench
can be pulled out easily.
Turn the crankshaft clockwise 2 turns, and after leaving
it in this position for 5 minutes or more, check again to
be sure that the auto tensioner 2 mm Allen wrench can
be pulled out or inserted easily.
NOTE
Even if the 2 mm Allen wrench cannot be easily inserted,
then it is satisfactory if the amount of protrusion of the
auto tensioner rod is within the standard value.
Standard value (A): 3.8 – 4.5 mm
If it is outside the standard value, repeat the operations
in steps 1 to 4.
4. Check to be sure that the timing marks on all sprockets
are aligned.
