9     1     1L-6957 轴承锁紧螺母     装配前,在螺纹上涂抹 Loctite C5A。    
拧紧至扭矩为
612 ± 68 N·m (451 ± 50 lb ft)。
10     2     9P-1478 垫片组     根据需要,使用厚度为
2.7 mm (0.11 in) 的垫片组以达到齿隙。 采用以下步骤达到齿隙:    
1. 利用适当的螺纹固定件 (1) 防止小齿轮转动。
2. 设置齿隙的同时,将固定件拧紧至最大扭矩为
7 N·m (62 lb in)。
3. 拆下固定件。
4. 移除轴承组件的端隙后应检查齿隙,齿隙必须为
0.20 to 0.42 mm (0.008 to 0.017 in)。
5. 在三个等距分布的齿上测量齿隙。
6. 齿的间隙不得大于
0.15 mm (0.006 in)。
