  1. 使用工具 (C) 拆掉旧轴承,同时安装新轴承 (6) 。 工具 (C) 的适配器应与连杆 (3) 的表面充分接触。

    注: 将轴承接头两端方位 (X) 正确调整在 12 ± 5 度范围内。


      注意

      在安装活塞销子轴承的时候,必须对连杆进行加热处理。 不要使用明火加热。


    1. 沿长度 (Y) 加热连杆 (3) 。

      (Y) 加热连杆的最大长度 ... 75 ± 5 mm (3.0 ± 0.2 in)

    1. 让连杆和轴承冷却到室温。

  1. 用下列程序安装活塞环 (4) 。

    1. 将控油环的弹簧安置在活塞体组件中的油环槽中。

    1. 将控油环安置在弹簧的上方。 安置控油环,使其开口与弹簧接头成 180 度。 使用工具 (A) 将控油环安装在活塞上。

    1. 使用工具 (A) 安装中间活塞环,使有 "UP-2" 标记的一侧朝向活塞顶部。

    1. 使用工具 (A) 安装顶部活塞环,使有 "UP-1" 标记的一侧朝向活塞顶部。

    1. 安置活塞环 (4) ,使端隙彼此相隔 120 度。

  1. 检查活塞环 (4) 的端隙。 请参阅技术规格, "活塞和活塞环"。

  1. 将活塞 (1) 放置在连杆 (3) 上。 将清洁的发动机机油涂抹在活塞销 (5) 上,并安装活塞销。 使用工具 (B) 安装挡圈 (2) 。 确保挡圈完全就位在活塞组件的环槽中。

End By: 安装活塞和连杆。 请参阅 拆解和组装, "活塞和连杆 - 安装"。
