INSTALLATION SERVICE POINTS

.

>>A<< CRANKSHAFT THRUST BEARING INSTALLATION
1. Install the two thrust bearings in the number 3 bearing bore 

in the cylinder block. For easier installation, apply engine oil 
to the bearings; this will help hold them in position.

2. The thrust bearings must be installed with their groove side 

toward the crankshaft web.

.

>>B<< CRANKSHAFT BEARING INSTALLATION
When bearing replacement is required, select and install the 
correct bearing by the following procedure.
1. Measure the crankshaft journal diameter and confirm its 

classification from the following table. In the case of a 
crankshaft supplied as a service part, identification 
colors/marks of its journals are painted/stamped at the 
positions shown in the illustration.

2. The cylinder block bearing bore diameter identification 

marks are stamped at the position shown in the illustration 
from left to right, beginning at No.1.

For example, if the crankshaft journal outside diameter identifi-
cation mark is "0" or identification color is "Yellow" and cylinder 
block bearing bore identification mark is "1," select a bearing 
whose identification mark is "2" or identification color is "Yellow" 
for number 1, 2, 4 and 5, and a bearing whose identification 
mark is "1" or identification color is "Green" for number 3.
If there is no identification color paint or no identification mark 
on the crankshaft, measure the journal outside diameter and 
select a bearing appropriate for the measured value.

3. Install the bearings having an oil groove to the cylinder 

block.

4. Install the bearings having no oil groove to the bearing cap.

.

>>C<< BEARING CAP/BEARING CAP BOLT INSTALLATION
1. Install the bearing caps so that 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 it exceeds the limit, 
replace the bolt.

Limit (A): 71.1 mm (2.79 inches)

3. Apply engine oil to the threaded portion and bearing surface 

of the bolt.

4. Tighten the bolts to 25 

± 2 N⋅m (18 ± 1 ft-lb) in the tightening 

sequence shown.

5. Make a paint mark on the head of each bolt.
6. Make a paint mark on the bearing cap at the position 90 

degree angle from the paint mark made on the bolt in the 
direction of tightening the bolt.

CAUTION

• If the bolt is overtightened, loosen the bolt completely 

and then retighten it by repeating the tightening proce-
dure from step 4.

• If the bolt is turned less than 90 degree angle, proper 

fastening performance may not be achieved. Be sure to 
turn the bolt exactly 90 degree angle.

7. Turn each bolt 90 degree angle in the tightening sequence 

specified in step 4, and make sure that the paint marks on 
the bolt and cap are aligned.

MD970389 or equivalent to the gasket surface of oil seal 
case.
NOTE: Be sure to install the case quickly while the sealant is 
wet (within 15 minutes).

2. Apply engine oil to the oil seal lip, and then install the oil seal
