注: 必须小心处理裂解式连杆。 当您松开连杆盖螺栓时,用软钳固定住连杆。 必要时使用软锤轻敲连杆盖。
(A) 轴承上的活塞销孔径 ... 46.035 ± 0.008 mm (1.8124 ± 0.0003 in)
(B) 连杆中活塞销轴承的孔径 ... 50.640 ± 0.013 mm (1.9937 ± 0.0005 in)
(C) 轴承节必须在任一位置 ± 5 度之内。
注: 必须加热连杆以便于安装活塞销轴承。 不要用喷枪。
(D) 可以将连杆加热至 175 至 260 °C (347 至 500 °F) 以便于安装活塞销轴承。 加热连杆的最大距离 ... 83.0 mm (3.27 in)
注: 组装活塞和连杆前,用清洁的发动机机油彻底润滑活塞销。
(E) 轴承中心点之间的距离 ... 217.00 mm (8.543 in)
(G) 连杆中曲轴轴承的孔径 ... 85.000 ± 0.013 mm (3.3465 ± 0.0005 in)

(1) 在这个位置上,在连杆和连杆盖上刻下气缸编号。 用数字 1 到 6 标记连杆和盖。 标记数字要在连杆上和轴承护圈凹槽 (3) 同侧进行。
注: 将连杆和活塞总成安装至发动机时使连杆组件的锻造零件号朝向发动机后侧。 发动机的后端是指发动机飞轮端。 在将连杆和活塞总成插入缸体之前先用清洁的发动机机油润滑连杆和活塞总成。
(2) 按照以下步骤拧紧连杆螺栓:
- 拧紧螺栓至扭矩为 50 ± 5 N·m (37 ± 4 lb ft)。
- 沿顺时针方向将每只螺栓转动 90 ± 5 度(1/4 圈)。
