ENGINE – Crankshaft and Flywheel11-71
ESEALANT APPLICATION TO OIL SEAL CASE
Specified sealant:
Mitsubishi Genuine Part No. MD970389 or equivalent
NOTE
(1) Be sure to install the case quickly while the sealant is
wet (within 15 minutes).
(2) After installation, keep the sealed area away from the
oil and coolant for approx. one hour.
INSPECTION
CRANKSHAFT OIL CLEARANCE (PLASTIGAGE
METHOD)
(1) Remove oil from the crankshaft journal and the crankshaft
bearing.
(2) Install the crankshaft.
(3) Cut the Plastigage to the same length as the width of
the bearing and place it on the journal in parallel with
its axis.
(4) Install the crankshaft bearing cap carefully and tighten
the bolts to the specified torque.
(5) Carefully remove the crankshaft bearing cap.
(6) Measure the width of the Plastigage at its widest part
by using a scale printed on the Plastigage package.
Standard value: 0.02 – 0.04 mm
Limit: 0.1 mm
CYLINDER BLOCK
(1) Visually check for scratches, rust, and corrosion.
Use also a flaw detecting agent for the check. If defects
are evident, correct, or replace.
(2) Using a straightedge and feeler gauge, check the block
top surface for warpage. Make sure that the surface is
free from gasket chips and other foreign matter.
Standard value: 0.05 mm
Limit: 0.1 mm
(3) If the distortion is excessive, correct within the allowable
limit or replace.
Grinding limit: 0.2 mm
Includes/combined with cylinder head grinding
Cylinder block height (when new): 284 mm
(4) Check cylinder walls for scratches and seizure. If defects
are evident, correct (bored to oversize) or replace.

DISASSEMBLY SERVICE POINTS
ATHROTTLE POSITION SENSOR AND IDLE AIR
CONTROL MOTOR REMOVAL
(1) Do not disassemble the sensor and motor.
(2) Do not immerse solvent to clean the sensor and motor.
Clean then with shop towel.
BTHROTTLE BODY REMOVAL
(1) Do not remove the throttle body.
(2) Check if the vacuum port or passage is clogged. Use
compressed air to clean the vacuum passage.
REASSEMBLY SERVICE POINT
ATHROTTLE POSITION SENSOR INSTALLATION
(1) Install the throttle position sensor to the throttle body
as shown in the diagram.
(2) Turn throttle position sensor 90° clockwise to set it, and
tighten screws.
(3) Check the continuity between terminal No. 3 (Idle throttle
position switch) and No. 4 (Earth).

If there is no continuity with the throttle valve fully closed,
turn the throttle position sensor counterclockwise, and
then check again.

REASSEMBLY SERVICE POINTS
ASTOP RING / SNAP RING INSTALLATION
Using a suitable pulling tool, pull overrunnig clutch stop ring
over snap ring.
INSPECTION
COMMUTATOR CHECK
(1) Place the armature in a pair of “V” blocks and check
the runout with a dial indicator.
Standard value: 0.05 mm
Limit: 0.1 mm
(2) Measure the commutator outer diameter.
Standard value: 32.0 mm
Limit: 31.4 mm
(3) Check the undercut depth between segments.
Standard value: 0.5 mm
BRUSH HOLDER CHECK
Check the continuity between brush holder plate and brush
holder.
If there is no continuity, the brush holder is in order.

OVERRUNING CLUTCH CHECK
(1) While holding clutch housing, rotate the pinion. Drive
pinion should rotate smoothly in one direction, but should
not rotate in opposite direction. If clutch does not function
properly, replace overrunnig clutch assembly.
(2) Inspect pinion for wear or burrs. If pinion is worn or burred,
replace overrunning clutch assembly. If pinion is damaged,
also inspect ring gear for wear or burrs.
FRONT AND REAR BRACKET BUSHING CHECK
Inspect bushing for wear or burrs. If bushing is worn or burred,
replace front bracket assembly or rear bracket assembly.
BRUSH AND SPRING REPLACEMENT
(1) Brushes that are worn beyond wear limit line, or oil-soaked,
should be replaced.
(2) When replacing ground brush, slide the brush from brush
holder by prying retaining spring back.
ARMATURE TEST
ARMATURE COIL SHORT-CIRCUIT TEST
(1) Place armature in a growler.
(2) Hold a thin steel blade parallel and just above while rotating
armature slowly in growler. A shorted armature will cause
blade to vibrate and be attracted to the core. Replace
shorted armature.
ARMATURE COIL EARTH TEST
Check the insulation between each commutator segment and
armature coil core.
If there is no continuity, the insulation is in order.

ON-VEHICLE SERVICE

REAR AXLE TOTAL BACKLASH CHECK
If the drive system roars or the vehicle vibrates, use the
following procedure to measure total backlash in the rear
axle. Based on the measurement taken, determine whether
the differential carrier assembly needs to be removed or not.
1. Place the shift lever in the neutral position and operate
the parking brake.
2. Turn the propeller shaft fully clockwise and make an
alignment mark on the companion flange dust cover and
gear carrier.
3. Turn the propeller shaft fully counterclockwise and
measure the deviation between the alignment marks.
Limit: 5 mm
4. If the backlash exceeds the limit, replace the differential
carrier assembly.
GEAR OIL LEVEL CHECK
DIFFERENTIAL
1. Remove the filler plug.
2. Check that the gear oil level is within the specified range
from the bottom end of the filler plug hole.
Standard value (A): 6 mm
3. If the gear oil level exceeds the standard value, add the
specified gear oil up to the bottom end of the filler plug
hole.
Specified gear oil:
Hypoid gear oil API classification GL-5 or higher
SAE viscosity Number 90, 80W.
NOTE
10C or more: #90, less than 10C: #80
4. Fit the filler plug and tighten it to the specified torque.
