CONNECTING ROD BEARING OIL CLEARANCE

Method by Calculation





- Install connecting rod bearings (1) to connecting rod (2) and connecting rod cap, and tighten connecting rod bolts to the specified torque. Disassembly and Assembly for the tightening procedure.
- Measure the inner diameter of connecting rod bearing with an inside micrometer.
(Oil clearance) = (Connecting rod bearing inner diameter) � (Crankshaft pin journal diameter)

Standard and limit : Refer to EM-148, "Connecting Rod Bearing". Specifications

- If the calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Description.

Method of Using Plastigage
- Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.
- Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil holes.
- Install connecting rod bearings to connecting rod and connecting rod bearing cap, and tighten connecting rod bolts to the specified torque. Disassembly and Assembly for the tightening procedure.

CAUTION:
Never rotate crankshaft.





- Remove connecting rod bearing cap and bearings, and using the scale on the plastigage bag, measure the plastigage width.

NOTE:
The procedure when the measured value exceeds the limit is the same as that described in the "Method by Calculation".

MAIN BEARING OIL CLEARANCE

Method by Calculation





- Install main bearings (3) to cylinder block (1) and lower cylinder block (2), and tighten lower cylinder block bolts to the specified torque. Disassembly and Assembly for the tightening procedure.
- Measure the inner diameter of main bearing with a bore gauge.
(Oil clearance) = (Main bearing inner diameter) � (Crankshaft main journal diameter)

Standard and limit : Refer to EM-147, "Main Bearing". Specifications

- If the calculated value exceeds the limit, select proper main bearing according to main bearing inner diameter and crankshaft main journal diameter to obtain the specified bearing oil clearance.
Description.

Method of Using Plastigage
- Remove engine oil and dust on crankshaft journal and the surfaces of each bearing completely.
- Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil holes.
- Install main bearing to cylinder block and lower cylinder block, and tighten lower cylinder block bolts with lower cylinder block to the specified torque. Disassembly and Assembly for the tightening procedure.

CAUTION:
Never rotate crankshaft.





- Remove lower cylinder block and bearings, and using the scale on the plastigage bag, measure the plastigage width.

NOTE:
The procedure when the measured value exceeds the limit is the same as that described in the "Method by Calculation".

MAIN BEARING CRUSH HEIGHT





- When lower cylinder block is removed after being tightened to the specified torque with main bearings (1) installed, the tip end of bearing must protrude. Disassembly and Assembly for the tightening procedure.

A : Crush height

Standard : There must be crush height.

- If the standard is not met, replace main bearings.

CONNECTING ROD BEARING CRUSH HEIGHT





- When connecting rod bearing cap is removed after being tightened to the specified torque with connecting rod bearings (1) installed, the tip end of bearing must protrude. Disassembly and Assembly for the tightening procedure.

A : Crush height

Standard : There must be crush height.

- If the standard is not met, replace connecting rod bearings.

LOWER CYLINDER BLOCK BOLT OUTER DIAMETER





- Measure the outer diameters (c), (d) at two positions as shown in the figure.

a : 20 mm (0.79 in)
b : 30 mm (1.18 in)
e : 10 mm (0.39 in)

- If reduction appears in (a) range, regard it (c).

Limit [(d) - (c)] : 0.11 mm (0.0043 in)

- If it exceeds the limit (large difference in dimensions), replace lower cylinder block bolt with new one.

CONNECTING ROD BOLT OUTER DIAMETER





1. Measure the outer diameters [(a), (b) and (c)] at the position shown in the figure.

a : Value at the end of the smaller diameter of the bolt
b : Value at the end of the smaller diameter of the bolt [opposite side of (a)]
c : Value of the smallest diameter of the smaller of the bolt

2. Obtain a mean value (d) of (a) and (b).
3. Subtract (c) from (d).

Limit [(d) - (c)] : 0.09 mm (0.0035 in)

4. If it exceeds the limit (large difference in dimensions), replace the bolt with new one.

FLYWHEEL DEFLECTION (M/T models)





- Measure the deflection of flywheel contact surface to clutch with a dial indicator (A).
- Measure the deflection at 210 mm (8.27 in) dia.

Standard : 0.45 mm (0.0177 in) or less.

- If measured value is out of the standard, replace flywheel.

MOVEMENT AMOUNT OF FLYWHEEL (M/T models)

CAUTION:
Never disassemble double mass flywheel.

Movement Amount in Radial (Rotation) Direction
Check the movement amount of radial (rotation) direction with the following procedure:
1. Install a bolt to clutch cover mounting hole, and place a torque wrench on the extended line of the flywheel center line.
- Tighten bolt at a force of 9.8 N�m (1.00 kg-m, 87 in-lb) to keep it from loosening.





2. Put a matching mark on circumferences of the two flywheel masses without applying any load (measurement standard points).

1 : Clutch cover mounting bolt
2 : Flywheel (transaxle side)
A : Torque wrench
b : 9.8 Nm (1.00 kg-m, 87 in-lb)

3. Apply a force of 9.8 N�m (1.00 kg-m, 87 in-lb) in each direction, and mark the movement amount on the mass on the transaxle side.
4. Measure the dimensions of movement amounts (C) and (D) on circumference of the flywheel on the transaxle side.

Standard: Less than 29.9 mm (1.177 in)

- If measured value is out of the standard, replace flywheel.

DRIVE PLATE (A/T models)





- Check drive plate and signal plate for deformation or damage.

CAUTION:
- Never disassemble drive plate.
- Never place drive plate with signal plate facing down.
- When handling signal plate, take care not to damage or scratch it.
- Handle signal plate in a manner that prevents it from becoming magnetized.
- If anything is found, replace drive plate.

OIL JET
- Check nozzle for deformation and damage.
- Blow compressed air from nozzle, and check for clogs.
- If it is not satisfied, clean or replace oil jet.

OIL JET RELIEF VALVE





- Using a clean plastic stick, press check valve in oil jet relief valve.
Check that valve moves smoothly with proper reaction force.
- If it is not satisfied, replace oil jet relief valve.
