TM 5-3895-368-14&P (6) Install ratchet wheel (28) over end of drive shaft (30) with teeth pointing in a counterclockwise     direction.          Seat     the ratchet wheel by turning to engage locking flat. (7) Install  washer  (27)  onto  drive   shaft   (30) and  guide  end  of  shaft   through   bushing (26), seating washer in recess of bushing. (8) Secure  drive  shaft  by  installing   retaining ring (31) into groove of drive shaft. (9) Apply  a  few  drops  of   SAE   10   grade   oil (MIL L-2104E) to flanged bushing (13) and install in bore of pawl (12) as shown. (10) Install washer (11), pawl (12) with bushing (13)  and  spring  (14)  on  bolt  (10).    Install assembly  into  base  (8),  engaging  ends  of spring  (14)  as  noted  during  disassembly, to apply torque to pawl to hold the pawl tip against   the   ratchet   wheel   (28).      Secure bolt  with  locknut  (9),  tightening  sufficiently to secure parts without restricting movement of pawl. (11) If removed, install bolt (18) through wall of reel  (17)  and  secure  clamp  (19)  with  nut (20). (12) Install   reel   (17),   spacer   (16),   and   thrust washer (15) into base (8) and secure with shaft (21) and locknut (9). (13) Apply  a  few  drops  of   SAE   10   grade   oil (MILL-2104E)   to   threads   of   handle   (25) and  install  handle  onto  end  of  drive  shaft (30),    turning    clockwise    until    a    clicking noise   is   heard.      Install   spring   (25)   as shown and secure with locknut (24).  Turn locknut   onto   end   of   shaft   until   end   of locknut is flush with end of shaft. (14) If    necessary    place    new    decal    (22)    on handle (23). a. Installation. (1) Install   the   hand   winch   as   instructed   in paragraph 2-4l. 4-5. Electric Hoist Repair Instructions. a. Removal. (1) Disconnect  the  power  cord  from  electrical power source. (2) Remove  drum  sling  (3,  Figure  2-12)  from lower hook of hoist (2). (3) Unhook  upper  hook  of  hoist  from  trolley and remove hoist from melter. b. Load Chain Replacement (Figure 4-4). (1) Remove  capscrew  (14),  lockwasher  (13), and   flat   washer   (12)   to   release   end   of loose  end  chain  (15)  from  motor  housing (56). (2) Mount  loose  end  block  (16)  in  vice  and with suitable drift, drive pin (18) from loose end block (16), and detach load chain (55) and stop block (19). WARNING EYE  PROTECTION  MUST  BE  WORN WHEN GRINDING OR CUTTING CHAIN.  FLYING PARTICLES CAN  BE PRODUCED, WHICH CAN CAUSE INJURY TO PERSONNEL. (3) Using a 7" minimum diameter of 1/8" thick abrasive   wheel    that    will    clear    adjacent links,  cut  a  portion  out  of  the  second  to last   link   (flat   link)   on   loose   end   of   load chain  (55).    Center  a  3/8"  long  cutout  on the weld of the link, to form a coupling link. Remove and discard the last link. (4) Attach new load chain (55) to the old chain with the coupling link just created.  Ensure that  the  first  link  of  the  new  chain  is  an upstanding  link  with  the  weld  facing  away from the liftwheel (21). (5) Attach   power   cord   to   a   110   Volt   power source and operate the hoist in the DOWN direction  until  approximately  2-1/2  feet  of new chain remains on the loose end side. Disconnect power cord. (6) The  last  link  on  the  loose  end  side  of  the new  load  chain  must  be  an  up-standing link.  If last link  is not an up-standing link, cut    it    off    using    cutting    procedure    as described in step 3, above. (7) Slide stop block (19) onto new load chain’s last  link  and  secure  that  link  to  loose  end block (16) with a new pin (18). (8) Attach  loose  end  chain  to  motor  housing (56) with flat washer (12), lockwasher (13), and capscrew (14). (9) Position the lower hook body (46) in a vice with the small end of tapered groove pin 4-5
