TM 10-3930-659-34 5-13.  TRANSMISSION OUTPUT SHAFT ASSEMBLY REPLACEMENT (Con’t). 11. Using   depth   gage   micrometer,   measure   and note  distance  from  top  of  output  shaft  (26)  to bearing contact surface (48). 12. Using   depth   gage   micrometer,   measure   and note  distance  from  top  of  output  shaft  (26)  to retaining ring (22). 13. Subtract   measurement   taken   in   step   12   from measurement  taken  in  step  11.    Difference  is end play. End play must be 0. -0.020 in. (0.3050.508   mm).      If   measurement   is   within specification, go to step 15. 14. Remove  retaining  ring  (22)  and  shim  (21)  from transmission  assembly  (1).    Replace  shim  with new  shim  thickness  required  to  meet  end  play specification in step 13. Install new shim and retaining ring on transmission assembly. 15. Install inner oil shield (38) on transmission assembly (1) with two washers (36) and screws (37).  Torque screws to 36 lb.-ft.  (49 N-m). 16. Remove retaining ring (22), shim (21), and output shaft (26) from transmission assembly (1). 17. Using    transmission    output    shaft    pipe    driver, install bearing (24), shim (20), and retaining ring (19) on transmission assembly (1). 18. Using    feeler    gage,    check    for    gap    between bearing  (24)  and  retaining  ring  (19).    If  no  gap exists, go to step 22. 19. Remove  retaining  ring  (19)  and  shim  (20)  from transmission  assembly  (1).    Replace  shim  with new  shim  thickness  required  to  eliminate  gap. Install new shim and retaining ring on transmission assembly. 5-129
