11. Insert
a special tool that injection top correction jig
(13)
into the crankshaft position sensor mounting
hole and align the center of handle and pulsar.
(13) Injection top correction jig
12. This position is the crank position sensor top dead
center
detection position so position the tri-square
(14) on the reference line (15) set in the previous
item and make a crank position sensor top dead
center detection position mark (16) on the flywheel.
(14) Tri-square
(15) Reference line
(16)
Mark of crankshaft position
sensor top dead center de-
tection position
13. Measure
the
difference (A) between the top dead
center mark (17) and the crankshaft position sensor
top dead center detection position mark (18).
(17) Mark for top dead center
(18) Mark of crankshaft position
sensor top dead center de-
tection position
(A)
Difference (mm)
14. Calculate the
fuel injection timing correction by
difference (A).
IMPORTANT
• 1 mm = 360° / (Flywheel Diameter × π)
•
If the crankshaft position sensor top dead
center detection position is in front of top
dead center, enter a negative value.
If the crankshaft position sensor top dead
center detection position is in back of top
dead center, enter a positive value.
NOTE
• Corrected
angle
= (360 / (flywheel diameter ×
π)) × difference (A)
15. Overwrite the injection timing correction value in the
engine ECU.
4.31 Adjusting air gap between
crankshaft position sensor and
flywheel
Tools required
• V
ernier caliper
• Depth gauge
1. Measure the
crankshaft position sensor length
between the sensor tip and sensor flange (1) face
with vernier caliper.
2. Measure the depth from sensor attaching face of
flywheel housing to flywheel side (2) surface with
depth gauge.
