NOTE: Some applications do not have a cooling fan or
the cooling fan is located elsewhere on the application.
For engines equipped with an engine driven cooling fan,
the fan holds the fan pulley and spacer in place. Install the
fan pulley and spacer.
If removed, install the cooling fan. Refer to the OEM
service manual for instructions.
NOTE: Use the tension of the drive belt to hold the
cooling fan in place when tightening the mounting
capscrews. Do not hold the fan blades to keep the cooling
fan from rotating.
Do not tighten the mounting capscrews at this time.
Tighten the mounting capscrews after the drive belt is
installed.

Finishing Steps
WARNING
Batteries can emit explosive gases. To reduce the
possibility of personal injury, always ventilate the
compartment before servicing the batteries. To
reduce the possibility of arcing, remove the negative

• Connect the batteries. Refer to the OEM instructions.
• Start the engine and check for proper operation.
Starting Motor
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.
