项目  数量  零件  技术规格说明 
凸轮轴驱动齿轮  组装前,使用饱含清洁液的无绒布擦去多余的机油,清洁凸轮轴锥面和凸轮轴驱动装置的锥形孔。 用酒精片清洁。
有关左右凸轮轴驱动齿轮的安装步骤,请参见拆解与组装。 
惰轮组件  安装后,惰轮组件上的 125-9751 衬套孔径为 81.060 ± 0.010 mm (3.1913 ± 0.0004 inch)
衬套的安装深度为 1.00 ± 0.25 mm (0.049 ± 0.010 inch)。 
101-1368 止推垫圈  新止推垫圈的厚度为 1.90 ± 0.10 mm (0.075 ± 0.004 inch)。 
齿轮组件  安装后,齿轮组件上的 101-1372 衬套孔径为 75.060 ± 0.010 mm (2.9551 ± 0.0004 inch)
衬套的安装深度为 1.5 ± 0.5 mm (0.06 ± 0.02 inch)。 
8M-2530 螺栓  拧紧至扭矩为 140 ± 10 N·m (103 ± 7 lb ft)。 
101-1366 齿轮轴  直径为 74.990 ± 0.010 mm (2.9524 ± 0.0004 inch)。 
9X-8887 螺栓  按以下步骤拧紧凸轮轴驱动齿轮的螺栓:

1. 拧紧凸轮轴驱动齿轮的螺栓至扭矩 360 ± 40 N·m (266 ± 30 lb ft)
2. 在凸轮轴驱动齿轮的螺栓头处画一条垂直线。 参考图 2。
3. 用冲头顶住凸轮轴驱动齿轮固定板。 用锤子敲击冲头 3 到 4 次。
4. 再次将凸轮轴驱动齿轮的螺栓拧紧至 360 ± 40 N·m (266 ± 30 lb ft)
5. 重复步骤 3 和步骤 4,直到螺栓上的标记至少转过 90 度。 参考图 3。 
1B-4367 螺栓  拧紧至扭矩为 240 ± 20 N·m (177 ± 15 lb ft)。 
8S-2331 螺栓  拧紧至扭矩为 240 ± 20 N·m (177 ± 15 lb ft)。 
10  101-1365 止推片  新止推片的厚度为 6.35 ± 0.25 mm (0.250 ± 0.010 inch)。 
11  101-1370 曲轴齿轮  齿轮组件 (4) 上的标记必须与曲轴齿轮 (11) 上的标记对准。 
12  101-1367 惰轮轴  直径为 81.000 ± 0.010 mm (3.1890 ± 0.0004 inch)。
