Connecting Rod Bearing Replacement On-Car Service

1. Disconnect the battery ground cable.
2. Drain the engine oil from oil pan.


3. Disconnect the high tension cable.

4. Remove the spark plug.

5. Support the engine by using an engine hoist.



v6. Engine Mount Remove the right side engine mount bolt (A) and engine mount bracket bolt (B). Then remove the body side engine mount cushion and the rear side torque rod.

7. Dust Cover

Remove the flywheel dust cover.



v8. Oil Pan

Remove the oil pan by using the seal cutter to shear sealant off.

Seal Cutter : J-37228 Note:

The sealant is applied to entire fitting face of oil pan. Do not pry it or you may distort the sealing flange.
v9. Connecting Rod Bearing

1. Measure the connecting rod thrust clearance. Use a feeler gauge to measure the thrust clearance at the big end of the connecting rod. If the clearance exceeds the specified limit, the connecting rod must be replaced. mm(in.)

Standard Limit

0.20 - 0.35
0.40 (0.0158)
(0.0079 - 0.0138)


v 2. Measure the oil clearance between the connecting
rod and the crankshaft as follows:

1) Remove the connecting rod cap nuts and the rod caps. Arrange the removed rod caps in cylinder number order.
2) Clean the rod bearings and the crankshaft pins.
3) Carefully check the rod bearings. If even one bearing is found to be damaged or badly worn, the entire bearing assembly must be replaced as a set. Reinstall the bearings in their original positions.



Apply plastigage to the crank pin as shown in Figure. v4) Reinstall the rod caps to their original positions. Tighten the rod caps.
Torque kg-m(ft.lbs.)

3.5 (25.3)

Note:

Do not allow the crankshaft to rotate.
5) Remove the rod caps.
6) Measure the width of the plastigage and determine the oil clearance. If the oil clearance exceeds the limit, replace the rod bearings as a set. mm(in.)

Standard Limit

0.025 - 0.058 0.12 (0.0047)
(0.0010 - 0.0023)

7) Clean the plastigage from the bearings and the crankshaft pins.



v10. Connecting-Rod Cap with Bearing vMatch the numbered caps with the numbers on the connecting rods. Align the punched marks on the connecting rods and caps. Apply engine oil to the threads. Alternately tighten the cap nuts to the specified torque in two or three phases.


v Torque kg-m(ft.lbs.)

v11. Oil Pan
1) Completely remove all residual sealant, lubricant and moisture from the connecting surfaces. The surfaces must be perfectly dry.
v 2) Apply a correct width bead of sealant (TB-1207C or
its equivalent) to the contact surfaces of the oil pan.
There must be no gaps in the bead.
3) The oil pan must be installed within 30 minutes after sealant application.
4) The engine must not be started within 30 minutes of installing the oil pan.
v 5) Tighten the bolts and nuts to the specified torque.

Torque kg-m(ft-lbs.)

v 12. Dust Cover

Install the flywheel dust cover.



v13. Engine Mount Bracket

Attach the engine mount cushion to the body, then lower the engine hoist gradually, aligning the bracket with the engine mount cushion. Tighten the bolts to the specified torque.
