Installation Notice
Make sure the crankshaft bearing cap properly seated
in place in the crankcase side. When perfectly installed, the projected part (arrow) locates in the leftside (intake manifold side).
Assemble so that the projected part of the cap and
crankcase face the same direction.
Removal & Installation Procedure
1. Unscrew the connecting rod bearing cap bolt and remove
the bearing cap. Installation Notice
2. Unscrew the crankshaft bearing cap bolts and separate the upper and lower bearing shells and thrust washers. Installation Notice
Remove the bearing cap from front (pulley side) to
rear.
Make sure that the upper and lower bearing shells do
not change each other and coat with engine oil.
The oil grooves (arrows) in the thrust washers must
face outward and insert the thrust bearing into the bearing cap.
There are five kinds of thrust washers by thickness.
Select the proper washer when repaired.
3. Remove the crankshaft.
4. Installation should follow the removal procedure in the reverse order.
5. After completion of the installation, check for the rotating condition of the crankshaft.
Make sure that the upper and lower bearing shells do
not change each other.
Coat the bearing shell with engine oil.
Install the bearing cap according to the consecutive
number.

Tools Required 104 589 01 01 00 Spanner
111 589 03 15 00 Insert Pin Inspection Procedure
1. Position the NO.1 cylinder piston to ATDC 20° by turning
the crankshaft Notice
When the ATDC 20 ° mark on vibration damper is aligned
with timing gear case cover, the intake and exhaust cam of cylinder will make the slope to the center and will face up.
In this way, the insert hole in NO.1 and NO.4 camshaftbearing cap will match in line with the flange hole forcamshaft sprocket.
2. Check the timing as below procedure;
- Check if the insert pin (111 589 03 15 00) can be inserted into the NO.1 and NO.4 bearing cap hole.
- At this condition, check if the ATDC 20 ° mark on vibration
damper aligns with the marker on the timing gear case.

Adjustment Procedure
1. Position the NO.1 cylinder to ATDC 20° .
2. Remove the chain tensioner.
3. Remove the exhaust camshaft sprocket.
4. Adjust the timing position with inserting the insert pin (f6.5mm, 111 589 03 15 00) into the NO.1 and NO.4
camshaft bearing cap hole and flange hole while rotating the camshaft by using wrench (104 589 01 01 00).
