(1) 垫圈
- 新垫圈的厚度 ... 8.50 ± 0.05 mm (0.335
± 0.002 in)
- 新凸轮轴中凹槽的厚度 ... 8.75 ± 0.05 mm (0.344 ± 0.002 in)
- 新凸轮轴的端隙 ... 0.15 至 0.35 mm (0.006 至 0.014 in)
- 新凸轮轴中凹槽的厚度 ... 8.75 ± 0.05 mm (0.344 ± 0.002 in)
(2) 轴颈表面
- 新凸轮轴轴承表面（轴颈）的直径 ... 85.88 ± 0.02 mm (3.381 ± 0.001 in)
- 组装后的凸轮轴轴承孔孔径 ... 86.00 ± 0.06 mm (3.386 ± 0.002 in)
(3) 定位销
- 以下数值为定位销从右后凸轮轴和左前凸轮轴处伸出的长度。 ... 22.0 ± 0.5 mm (0.87 ± 0.02 in)
(4) 螺栓
-
彻底清洁螺栓的螺纹以及零件的接触面。
- 手动将螺栓拧紧至以下扭矩。 ... 55 ± 7 N·m (40 ± 5 lb ft)
(6) 凸轮轴凸轮高度
请使用以下步骤来确定这一高度：
- 测量凸轮轴凸轮高度 (5) 。
- 测量基圆 (7) 。
- 用凸轮高度（步骤2 ）减去基圆（步骤1 ）。 二者之差即为实际凸轮升程。
- 规定的凸轮轴凸轮升程 (6)
进气凸轮 (8) ... 9.314 mm (0.3667 in)
喷油器凸轮 (9) ... 13.731 mm (0.5406 in)
排气凸轮 (10) ... 9.078 mm (0.3574 in)
