Removal and Installation

REMOVAL AND INSTALLATION

CAUTION:
Do not remove any of the bolts "A" of the flywheel shown in the illustration. The balance of the flexible type flywheel is adjusted in an assembled condition. Removing the bolt, therefore, can cause the flexible flywheel to be out of balance, causing damage.

REMOVAL SERVICE POINT

[[A]]
FLYWHEEL BOLT / DRIVE PLATE BOLT LOOSENING









1. Install special tool MD998781 to hold the flywheel or drive plate.
2. remove the flywheel bolt or drive plate bolt.

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 grooved side facing toward the crankshaft web.

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 marks of its journals are 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 Number 1.










For example, if the crankshaft journal outside diameter identification mark is "0" and cylinder block bearing bore identification mark is "1," select a bearing whose identification mark is "2" for number 1, 2, 4 and 5, and a bearing whose identification mark is "1" for number 3.
If there is 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.

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: 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 the specified torque in the tightening sequence shown.
Tightening torque: 25± 2Nm (18± 1 ft-lb)






5. Make a paint mark on the head of each bolt.

CAUTION:

- When the tightening angle is smaller than the specified tightening angle, the appropriate tightening capacity cannot be secured.
- When the tightening angle is larger than the specified tightening angle, remove the bolt to start from the beginning again according to the procedure.

6. Make a paint mark on the bearing cap 90 degrees from the paint mark made on the bolt, in the direction of tightening the bolt.
7. Turn each bolt 90 degrees in the tightening sequence specified in step 4, and make sure that the paint marks on the bolt and cap are aligned.





8. Make sure that the crankshaft turns smoothly and the end play is correct. If the end play exceeds the limit, replace the number 3 crankshaft bearings.
Standard value: 0.05 - 0.25 mm (0.002 - 0.009 inch)
Limit: 0.40 mm (0.015 inch)

OIL SEAL INSTALLATION





Using special tools MD998776 and MB990938, press-fit the oil seal in the case.

]]E[[
SEALANT APPLICATION TO OIL SEAL CASE





1. Apply sealant Three bond 1207F 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 case onto the cylinder block.
NOTE:
After installation, keep the sealed area away from the oil for approximately one hour.

FLYWHEEL BOLT / DRIVE PLATE BOLT INSTALLATION









1. Install special tool MD998781 to hold the flywheel or drive plate.
2. Tighten the flywheel bolt or drive plate bolt to the specified in the tightening sequence shown.
Tightening torque: 132± 5Nm (98± 3 ft-lb)
