松动、磨损或损坏的Rosan螺柱和嵌件需采用不同方法进行修复。步骤(1)说明如何更换Rosan螺柱，步骤(2)说明如何更换Rosan嵌件。请参见图408。

(1) Replace defective Rosan studs.

更换损坏的（有缺陷的）Rosan螺柱

CAUTION: EXERCISE CARE NOT TO DAMAGE ASSEMBLY IN WHICH STUD IS INSTALLED.

注意：安装螺柱时需小心，避免损坏组件。

(a) Cut stud off approximately flush with surface of parent material. Center punch over flat end of stud.

将螺柱切割至与母材表面大致齐平，在螺柱的平头端进行中心冲孔。

(b) Use a slightly oversize drill bit, large enough to cut inner serrations of lock ring. Remove enough of stud to remove serrations.

使用稍大尺寸的钻头，其直径需足以切除锁环的内锯齿。钻除足够的螺柱部分以消除锯齿。

在螺柱上钻一小孔，以便安装适配的“easyout”工具。

CAUTION: DO NOT ALLOW “EASYOUT” TO CATCH ON LOCK RING.

注意：切勿让“EASYOUT”卡在锁环上。

(d) Install “easyout” tool into stud and remove out of assembly.

将“easyout”工具装入螺柱后从组件中取出。

NOTE: The remainder of lock ring must come out with the stud.

注：锁环残余部分必须随螺柱一同取出。

WARNING: USE THE CORRECT PERSONAL PROTECTION. COMPRESSED AIR WILL CAUSE LOOSE PARTICLES THAT CAN GET IN YOUR EYES. COMPRESSED AIRFLOW CAN CAUSE CUTS, DO NOT POINT IT AT YOUR SKIN.
