C.
If the “LEFT TDC” light is on when the SynchroLASAR
®
is turned on, rotate the housing of the left
magneto clockwise for left rotation magnetos or counterclockwise for right rotation magnetos (as
viewed facing magneto distributor blocks) until the “LEFT TDC” light turns off. After the light turns
off, rotate the housing of the left magneto in the opposite direction until the “LEFT TDC” light just
turns on. Proceed to step D.
D.
Alternately tighten the nuts securing the mounting clamps of the left magneto to 8 ft/lbs of torque.
Continue to tighten both nuts alternately in several steps to 17 ft/lbs of torque.
CAUTION
:
DO NOT EXCEED 17 ft/lbs OF TORQUE. DAMAGE TO THE MAGNETO MOUNTING
FLANGE MAY RESULT, RENDERING THE UNIT NON-AIRWORTHY.
2.2.10 Align Engine Crankshaft to the Base Timing Angle Position
A.
Rotate the engine crankshaft backwards until the magneto “LEFT BKR PT” light on the
SynchroLASAR
®
turns on and then turns off.
B.
Slowly turn the crankshaft forward until the “LEFT BKR PT” light on the SynchroLASAR
®
tool
turns on.
C.
The engine crankshaft should be positioned approximately at the Base Timing Angle position.
2.2.11 Synchronize Left and Right Magneto Contact Points
A.
If the “RIGHT BKR PT” light is off when the SynchroLASAR
®
is turned to the “ON” or “RIGHT
BKR PT” position, rotate the housing of the right magneto counterclockwise for left rotation
magnetos or clockwise for right rotation magnetos (as viewed facing the magneto distributor
blocks) until the “RIGHT BKR PT” light turns on. Proceed to Step C.
B.
If the “RIGHT BKR PT” light is on when the SynchroLASAR
®
is turned to the “ON” or “RIGHT
BKR PT” position, rotate the housing of the right magneto clockwise for left rotation magnetos or
counterclockwise for right rotation magnetos (as viewed facing the magneto distributor blocks)
until the “RIGHT BKR PT” light turns off. After the light turns off, rotate the housing of the right
magneto in the opposite direction until the “RIGHT BKR PT” light just turns on. Proceed to Step
C.
C.
Alternately tighten the nuts securing the mounting clamps of the right magneto to 8 ft/lbs of
torque. Continue to tighten both nuts alternately in several steps to 17 ft/lbs of torque.
CAUTION:
DO NOT EXCEED 17 ft/lbs OF TORQUE. DAMAGE TO THE MAGNETO MOUNTING
FLANGE MAY RESULT, RENDERING THE UNIT NON-AIRWORTHY.
2.2.12 Check Sensor and Point Synchronization
A.
Rotate the engine backwards from cylinder number one TDC approximately 45°. Rotate the
engine in the forward direction until the “LEFT TDC” light turns off. Continue to slowly rotate the
engine in the forward direction until the “LEFT TDC” light just turns on. The crankshaft position
must be at TDC (0° ± 1°).
B.
Rotate crankshaft backwards until “LEFT BKR PT” and “RIGHT BKR PT “ lights turn off.
C.
Rotate crankshaft forward. “LEFT BKR PT” and “RIGHT BKR PT” should both turn on at the
Base Timing Angle position.
