For example, if the crankshaft journal outside diameter
ID color is “yellow” and cylinder block bearing bore ID
mark is “1”, select a bearing whose ID mark is “1”.
If there is no ID color paint on the crankshaft, measure
the journal outside diameter and select a bearing
appropriate for the measured value.
(2) Install the bearings having an oil groove to the cylinder
block.
(3) Install the bearings having no oil groove to the bearing
cap.
CBEARING CAP / BEARING CAP BOLT
INSTALLATION
(1) Install the bearing caps so the arrow points to the timing
belt side.
(2) Before installing the bearing cap bolts, check that the
shank length of each bolt meets the limit. If the limit is
exceeded, replace the bolt.
Limit: Max. 71.1 mm
(3) Apply engine oil to the threaded portion and bearing
surface of the bolt.Crankshaft bearing size

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.

ENGINE – Alternator11-82
RECTIFIERS CHECK
(1) Inspect the (+) heat sink by checking the continuity
between the (+) heat sink and stator coil lead wire
connection terminal using a tester probe.
If there is a continuity at both, the diode is short circuited,
so replace the rectifier.
(2) Inspect the (–) heat sink by checking the continuity
between the (–) heat sink and stator coil lead wire
connection terminal using a tester probe.
If there is a continuity at both, the diode is short circuited,
so replace the rectifier.
(3) Check the diode trio by connecting an ohmmeter to both
ends of each diode and check the continuity of the three
diodes.
If there is a continuity at both ends, or if there is no
continuity, the diode is damaged so replace the recitifier.
BRUSH CHECK
(1) Measure the length of the brush protrusion shown in the
illustration, and replace the brush if the measured value
is below the limit value.
Limit: 2 mm or less
(2) The brush can be removed if the solder of the brush
lead wire is removed.
(3) When installing a new brush, insert the brush into the
holder as shown in the illustration, and then solder the
lead wires.

AVACUUM HOSE CONNECTION
Insert securely and completely until the vacuum hose at the
engine side contacts the edge of the hexagonal part of the
fitting, and then secure by using the hose clip.
BCLEARANCE ADJUSTMENT BETWEEN BRAKE
BOOSTER PUSH ROD AND PRIMARY PISTON
Calculate clearance A from the B, C and D measurements.
A = B – C – D
Standard value: 0.65–0.85 mm
If the clearance is not within the standard value range, adjust
by changing the push rod length by turning the screw of
the push rod.
