IMPORTANT: The preferred method for installing the stator shaft bushing is to use J 43774  and a press. See Special Tools . If a press is not available, use J 43774  and J 8092  universal driver. If the bushing will be installed without a press, install the large end of J 43774  (2) onto J 8092  (1). See Special Tools .
11. Install a new bushing (3) onto J 43774  . See Special Tools .
12. Drive the bushing into the stator shaft (4) until the bushing is seated.

    Specification:  The bushing installed depth measurement is flush to 0.25 mm (0.010 in) below the stator shaft surface.
