表 1
所需工具 
工具  零件号  零件描述  数量 
4C-3601  活塞环扩展器 
C(1)   208-7630  环槽量规 
(1) 只在 C-12 发动机上使用工具。


注意

保持所有零件清洁无杂质。

杂质会造成快速磨损和缩短部件寿命。



注意

验证活塞和连杆是否正确组装。 确保连杆和连杆盖上刻的号码处在正确的位置。 连杆和连杆盖的标号对应应该安装的气缸。



注意

不要使用硬表面工具来安装螺塞。 安装期间不要击打或撞击螺塞。 如果螺塞掉落,则换成另一个新螺塞。


    注: 在某些发动机上,可能在活塞顶部上冲压有 "FRONT"(前)字样。 安装活塞时,确保 "FRONT"(前)字朝向发动机的前部。 放入相应的气缸中时,连杆上刻的编号必须朝向发动机右侧。 确保活塞冠和刻下的编号位置正确。

    注: 检查所有活塞环槽的情况。 使用工具 (C) 确认顶部环槽直径。 有关更多信息,请参阅工具操作手册, NEHS0840。

    注: 确保轴承 (6) 位于正确的位置。

  1. 将活塞冠 (2) 安装到活塞裙 (4) 上。 将活塞组件安装到连杆 (7) 上。 将清洁的发动机机油涂抹在活塞销 (5) 上,并安装销。 安装新螺塞 (3) 。

  2. 检查活塞环 (1) 的端隙。 参见技术规格手册, "活塞和活塞环"一节。

    注: 油环必须安装在弹簧上,并且两端的缝隙与油环弹簧接缝相差 180 度。

  3. 安装控油环。 应从活塞环端隙转动弹簧两侧 180 度。 从环两端缝隙中必须能够看见弹簧的白色部分。

  4. 安装中间活塞环时使标有 "UP-2" 的一侧朝向活塞顶部。 使用工具 (A) 安装活塞环。

  5. 安装顶活塞环时使标有 "UP-1" 的一侧朝向活塞顶部。 使用工具 (A) 安装活塞环。

  6. 安装后,全部三个活塞环 (1) 应彼此相差 120 度。

结束:

  1. 安装活塞和连杆。 请参阅拆解和组装, "活塞和连杆 - 安装"。
