3. Remove the sensor (2).

4. Use a soft, dry cloth in order to clean any debris

from the sensor (2).

Note: Do not use a wire brush in order to clean the

sensor. Do not use abrasive material in order to clean

the sensor.

5. Install Tooling (A). Use Tooling (A) in order to

rotate the engine. Rotate the engine in order to

align a tooth on the ring gear with the center of the

tapped hole.

6. By hand, carefully install the sensor (2) until light

contact is made with the ring gear.

Note: Do not tighten the sensor.

7. Unscrew the sensor (2) by half of one full turn in

order to obtain a clearance (X) of 0.5 to 0.8 mm

(0.02 to 0.03 inch).

8. Tighten the locknut (1). Do not allow the sensor (2)

to rotate. Connect the connection (3).

9. Remove Tooling (A).

10. Restore the electrical supply to the engine.

Starting Motor - Inspect

If a starting motor fails, the engine may not start in an

emergency situation. A scheduled inspection of the

starting motors is recommended.

Note: Problems with the electric starting motor can

be caused by the following conditions: malfunction of

the solenoid and malfunction of the electric starting

system.

Inspect the electrical system for the following

conditions:

• Loose connections

• Corrosion

• Wires that are worn or frayed

• Cleanliness

Make repairs, if necessary.

The starting motor pinion and the flywheel ring gear

must be in good condition in order for the engine to

start properly. The engine will not start if the starting

motor pinion does not engage the flywheel ring gear.

The teeth of the starting motor pinion and the

flywheel ring gear can be damaged because of

irregular engagement.

Inspect the starting motors for proper operation.

Listen for grinding when the engine is started. Inspect

the teeth of the starting motor pinions and the

flywheel ring gear. Look for patterns of wear on the

teeth. Look for teeth that are broken or chipped. If

damaged teeth are found, the starting motor pinions

and the flywheel ring gear must be replaced.

Turbocharger - Inspect

Periodic inspection and cleaning are recommended

for the turbochargers. Fouling of the turbine wheels

g01237854

can contribute to loss of engine power and overall

loss of engine efficiency.

If a turbocharger fails during engine operation,

damage to the turbocharger compressor wheel and/

or to the engine may occur. Damage to a

turbocharger compressor wheel could allow parts

from the compressor wheel to enter an engine

cylinder. This debris can damage the pistons, the

valves, and the cylinder head.
