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

(4) Tighten the bolts to 25 Nm in the specified tightening
sequence.
(5) Make a paint mark on the head of each bolt.
(6) Make a paint mark on the bearing cap at the position
90° from the paint mark made on the bolt in the direction
of tightening the bolt.
(7) According to the specified tightening sequence, give a
90° turn to each bolt and make sure that the paint mark
on the bolt and that on the cap are in alignment.
Caution
If the bolt is turned less than 90°, proper fastening
performance may not be expected. When tightening
the bolt, therefore, be careful to give a sufficient turn
to it.
(8) After installing the bearing caps, make sure that the
crankshaft turns smoothly and the end play is correct.
If the end play exceeds the limit, replace No. 3 crankshaft
bearings.
Standard value: 0.05 – 0.25 mm
Limit: 0.4 mm
DOIL SEAL INSTALLATION
Using the special tool, knock the oil seal into the oil seal
case.

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.

BRACKET / SPECIAL BOLT INSTALLATION
1. When installing the steering lock cylinder and steering
lock bracket to the column tube, temporarily install the
steering lock in alignment with the column boss.
2. After checking that the lock works properly, tighten the
special bolts until the head twists off.
Caution
The steering lock bracket and bolts must be replaced
