Timing Plate In Stored Position
(6) Timing Plate.
Timing Plate Rotated 180°
(6) Timing Plate.
NOTE
Engine timing can be measured at not only engine
crankshaft pulley but also flywheel assy. The
measurement of engine timing at crankshaft pulley is
exact but it is difficult and dangerous. The
measurement of engine timing at flywheel side is safe,
but it is need to adjust zero position of timing plate like
the followings brfore measurement of engine timing.
1) Pull out key from key switch.
2) Remove timing plate(6) from the converter housing.
The flywheel shoulder has a single timing mark on
it. Put a white chalk mark on it, so it can be seen
more easily.
3) Rotate timing plate (6) 180° and mount it on the
converter housing again, using the other mounting
holes on plate (6). When plate (6) is mounted, the
timing marks should be close to the flywheel as
shown.
4) Rotate engine and align the timing mark of engine
crankshaft pulley to zero degree position of timing
indicator near crankshaft balancer.
5) Note the timing mark on the flywheel indicates
which position of timing plate(6). If timing mark does
not indicate zero degree position of timing plate(6),
the correct zero position should be marked on the
timing plate.
