INSTALLATION INFO
INSPECT PINION GEAR
After cranking the engine several times, you can inspect
the witness pattern on the pinion gear. The pattern should
show 1/4" to 3/8". If over, the internal shim is required.
SLOW CRANKING
The most common cause is due to low input voltage. The
battery should be checked, but also inspect the battery
wires, terminals, connections or switches.
