S6A Disassembly Procedure 1. Loosen all 24 Cover Bolts (16) and drain the oil from the unit. 2. Remove   the   24   Cover   Bolts   (16)   and   lift   off Cover  (6).    Remove  O  Ring  Seal  (5)  from  the Cover Counterbore and discard. 3. Remove   Thrust   Washer   (7)   from   the   internal counterbore of the Cover (6). 4. Remove Input Gear (8) from First Stage Carrier Planet Gears (3F). 5. Remove  Thrust  Washer  (12).    Thrust  Bearing (13)  and  Thrust  Washer  (14)  from  First  Stage Carrier (3A).  NOTE: Thrust  Washer  (12)  may  have  stuck  to  Cover (6) as it was removed in Step 2. 6. Lift First Stage Carrier Assembly (3A-F). 7. Remove Thrust Washer (9) from end of Second Stage   Sun   Gear   (11).      This   Thrust   Washer would  have  been  removed  from  its  location  on Input Gear (8) during Step 4. 8. Remove Thrust Bearing Carrier (10). 9. Remove Second Stage Sun Gear (11). 10. Remove   Thrust   Washer   (12),   Thrust   Bearing (13) and Thrust Washer (14) from Second Stage Carrier     (2A)     counterbore.          NOTE:     Thrust Washer (12) may have stuck to Thrust Bearing Carrier as it was removed in Step 8. 11. Remove Ring Gear (4) from mesh with Second Stage  Carrier  Assembly  (2A-G).    Find  O  Ring (5), remove and discard. 12. Remove  Second  Stage  Carrier  Assembly  from engagement with Output Shaft(1A) 13. Remove Retaining Ring (1J) from the Retaining Ring Groove in Output Shaft (1A). Eye    protection    should    be    worn    during    this Retaining Ring removal. 14. Remove Bearing Spacer (1H) from Output Shaft (1A) and Bearing Cone face (1F). 15. The Output Shaft (1A) may now be pressed out of Hub (16). 16. Bearing Cups (1C & 1E) will remain in Hub (1G) as  will  Bearing  Cone  (1F).    Bearing  Cone  (1D) will remain on Output Shaft (1A).  Seal (1B) will be automatically removed during this procedure. NOTE: Should Bearing replacement be necessary,  the  Bearing  Cups  (1C  & 1E,   can   be   removed   with   a   "slide hammer"  puller  or  driven  out  with  a punch. WARNING: When    rebuilding    the    unit,    the    O' Rings   and   Retaining   Rings   should always be replaced. To    remove    Planet    Gears    from    the    Carrier Assemblies,   tap   Roll   Pins   (2G)   &   (3D)   into Planet Pins (2E) & (3E).  Tap Planet Pins (2E) & (3E)   out   of   location   in   the   Carrier   Assembly. Roll   Pins   (2G)   &   (3D)   may   now   be   driven through  Planet  Pins  (2E)  &  (3E).    Slide  Planet Gears (2F) & (3F), Thrust Washers (2B) & (3B) out   of   Carriers   (2A)   &   (3A).      Remove   Roller Bearings (2C) & (3C) from Planet Gears (2F) & (3F).  Remove Spacer (2D) from Second Stage Planet Gear (2F).
