- MD998718: Crankshaft Rear Oil Seal Installer

INSTALLATION SERVICE POINTS

]]A[[
KNOCK SENSOR BRACKET INSTALLATION





Check that the bracket is in proper contact with the cylinder block boss and tighten to the specified torque in the order shown.
Tightening torque: 28± 2Nm (21± 1 ft-lb)

CRANKSHAFT BEARING INSTALLATION





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 color of its journals are painted 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 Number 1.










3. From the above table, select a bearing whose size is appropriate for the crankshaft journal outside diameter. If the crankshaft journal outside diameter ID color is "yellow" and the cylinder block bearing bore ID mark is "III," for example, select a bearing whose ID color is "green" [Number 1, 4]
or "red" [Number 2, 3].
If there is no ID color paint on the crankshaft, measure the journal outside diameter and select a bearing appropriate for the measured valve.





4. Install bearings with the groove toward the cylinder block.
5. Install the bearings having no groove to the bearing cap.

THRUST BEARING INSTALLATION





1. Install the thrust bearing in the Number 3 bearing bore in the cylinder block and in the bearing cap. 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 toward the crankshaft weight side.

]]D[[
BEARING CAP /
BEARING BOLT INSTALLATION





1. Attach the bearing cap on the cylinder block as shown in the illustration.

2. Tighten the bearing cap bolts to specified torque in the sequence shown in the illustration.
Tightening torque: 74± 4Nm (54± 3 ft-lb)


3. Check that the crankshaft rotates smoothly.





4. Check the end play. If it exceeds the limit value, replace the thrust bearing.
Standard value: 0.05 - 0.25 mm (0.002 - 0.009 inch)
Limit: 0.3 mm (0.01 inch)
