Crankshaft

Inspection

Clean the crankshaft oil passages with pipe cleaners

or a suitable brush.

Check the keyway and threads.

Alignment

Measure runout on all main journals to make sure the

crankshaft is not bent.

The difference between measurements on each journal

must not be more than the service limit.

Crankshaft Total Runout:

Standard (New): 0.020 mm (0.0008 in) max.

Service Limit: 0.030 mm (0.0012 in)

DIAL INDICATOR

Rotate two complete

revolutions.

Support with lathe-

type tool or V-blocks.
Out-of-Round and Taper

Measure out-of-round at the middle of each rod and

main journal in two places.

The difference between measurements on each journal

must not be more than the service limit.

Journal Out-of-Round:

Standard (New): 0.004 mm (0.0002 in) max.

Service Limit: 0.010 mm (0.0004 in)

Measure out-of-

round at middle.

Measure taper at edges of each rod and main journal.

The difference between measurements on each journal

must not be more than the service limit.

Journal Taper:

Standard (New): 0.005 mm (0.0002 in) max.

Service Limit: 0.010 mm (0.0004 in)
Measure taper

at edges.ProCarManuals.com

Check for Wear and Damage

The starter should crank the engine smoothly and steadily.

If the starter engages, but cranks the engine erratically,

remove it, and inspect the starter drive gear and torque

converter ring gear for damage.

• Check the drive gear overrunning clutch for binding

or slipping when the armature is rotated with the

drive gear held. If the clutch is damaged, replace the

clutch assembly.

Check Cranking Voltage and Current Draw

Cranking voltage should be no less than 8.0 volts.

Current draw should be no more than 450 amperes.

If cranking voltage is too low, or current draw too high,

check for:

Dead or low battery

Open circuit in starter armature commutator segments

Starter armature dragging

Shorted armature winding

Excessive drag in engine

Check Cranking rpm

Engine speed during cranking should be above 100 rpm.

If speed is too low, check for:

Loose battery or starter terminals

Excessively worn starter brushes

Open circuit in commutator segments

Dirty or damaged helical spline or drive gear

Defective drive gear overrunning clutch

Check Starter Disengagement

With the shift lever in or , turn the ignition switch to

"START (III)", and release to "ON (II)". The starter drive

gear should disengage from the flywheel ring gear when

you release the key.

If the drive gear hangs upon the flywheel ring gear, check

for:

• Solenoid plunger and switch malfunction

• Dirty drive gear assembly or damaged overrunning
