IMPORTANT: DO NOT insert timing pin full depth into
cylinder block crankshaft timing hole
when rotating engine flywheel until
double slot on camshaft timing lobe is
at approximately 11 o’clock (viewed
from rear of engine) to avoid crankshaft
counterweight bending timing pin.
5. Slightly move engine flywheel back and forth with
turning tool until a second JDG971 Timing Pin (C) can
be installed in slot in crankshaft. This ensures that
camshaft and crankshaft are in sync (properly timed).
If timing pin does not enter crankshaft timing slot,
crankshaft is not properly timed with camshaft.
Crankshaft MUST BE timed to camshaft. (See CHECK
AND ADJUST CAMSHAFT-TO-CRANKSHAFT TIMING
in Group 050.)
