Rotation Check
If the starter solenoid is making a sound but the engine is
not rotating, turn the keyswitch to the OFF position, and
attempt to bar the crankshaft in both directions.
Bar the engine with the barring tool, Part Number
3824591.
If the crankshaft will bar over, attempt to start the engine.
If the starter motor cranks the engine, check the starter
motor pinion gear and flywheel ring gear for damage.
If damage to the starter motor pinion gear and/or flywheel
ring gear is found when replacing the components, make
sure to measure the distance from the starting motor
mounting flange to the forward face of the front side of the
flywheel ring gear. Follow the measure step of this
procedure.
