Finding Top Center Position for No. 1 Piston

Usage:

CG137-08 FPL

表 1
所需工具     数量    
5P-7306     轴壳体     1    
9S-9082     发动机盘车工具     1    
136-4632     正时销     1    
214-7340     棘轮扳手总成     1    

所有正时程序的起始点都是 1 号活塞位于压缩冲程上止点位置。

  1. 拆下起动马达。

  1. 拆下气门室盖。

    安装发动机盘车工具

    (1) 飞轮壳中正时端口的位置

    (2) 飞轮上定位 1 号活塞上止点的孔

    (3) 9S-9082 发动机盘车工具

    (4) 5P-7306 轴壳体

    (5) 214-1740 棘轮扳手总成

    注: 发动机两侧的飞轮壳中各有一个正时端口,可以容纳正时销。

  1. 安装工具 (3) 、 (4) 和 (5) 。 从飞轮壳正时端口 (1) 上拆下螺塞。 将 136-4632 正时销 拧入飞轮壳体中的加工孔中。

  1. 使用棘轮逆时针旋转曲轴,直到正时销落入飞轮中的孔 (2) 。 此时 1 号活塞处于上止点位置。

    注: 如果您将飞轮转动超过了正时螺栓安装的地方,必须将飞轮顺时针转动至少 30 度。 然后,逆时针旋转飞轮,直到正时销落入飞轮中的孔。 此步骤会消除齿轮间隙。

    1 号气缸摇臂位置

  1. 如果 1 号活塞在压缩冲程上,1 号活塞的进气门和排气门关闭。

    在摇臂和气门之间会有一些自由间隙。 摇臂必须足够松动,可以用手上下移动。

如果 1 号活塞看起来不在压缩冲程,进行下列步骤:

  1. 拆下正时螺栓。

  1. 逆时针方向将曲轴转动360度。

    注: 如果您将飞轮转动超过了正时螺栓安装的地方,必须将飞轮顺时针转动至少 30 度。 然后,逆时针旋转飞轮,直到正时销落入飞轮中的孔。 此步骤会消除齿轮间隙。

  1. 安装正时销。

    通过检查摇臂间隙确认此时 1 号活塞位于压缩冲程的上止点位置。
