4.Check the connecting rod bearing clearances. Follow Steps 5 and 6

for the correct installation procedures and tightening procedures for the connecting rod bearing caps when the clearance check is performed. Refer to Disassembly and Assembly, "Bearing Clearance - Check".

4、检查连杆轴承间隙。按照步骤5和6正确的安装步骤，当清理检查完

成时，收紧连杆轴承盖。参照拆装，“轴承间隙-检查”。

Bearing clearance（间隙） (new bearings) ... 0.062 to 0.160 mm

(0.0024 to 0.0063 inch)

轴承间隙（新轴承）... 0.062至0.160毫米（0.0024至0.0063英寸）Maximum permissible（允许的） bearing clearance (used bearings) ...

0.20 mm (0.008 inch)

最大允许轴承间隙（旧轴承）... 0.20毫米（0.008英寸）

5.Lubricate the threads of bolts (1) and the seating faces of

connecting rod bearing cap (2) with Tooling (B). Install connecting rod bearing cap (2) and bolts (1). Ensure that the number on the side of the connecting rod bearing cap is on the same side as the number on the connecting rod.

5、用工具B润滑线程螺栓（1）和连杆轴承盖（2）座面。安装连杆轴承

盖（2）和螺栓（1）。确保连杆轴承盖边上的编号与连杆上的编号相同。

6.Tighten bolts (1), as follows:

6、拧紧螺栓（1），具体如下：

a.Tighten the bolts to a torque of 90 ± 8 N·m (65 ± 6 lb ft).

a、拧紧螺栓到90 ± 8牛顿•米扭矩（65 ± 6磅•英尺）。

b.Put a mark on each bolt and on each connecting rod bearing

cap.

b、把每一个螺栓和连杆轴承盖做标记。

c.Tighten each bolt for an additional 90 ± 5 degrees (1/4

turn).

c、拧紧每个螺栓额外90 ± 5度，每个螺栓（1 / 4转）。

7.Repeat Steps 1 through 6 in order to install the remainder of the

connecting rod bearings.

7、重复步骤1到6以安装连杆轴承的其余部分。

End By: Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install".

结束工作：安装发动机油泵。参照拆卸和组装，“发动机油泵-安装”。
