and    tighten    screws    (61).        Torque screws (61) to 21 lb-ft (35 Nm). (b) Position the weights (60) and brackets (59)  on  the  inside  face  of  gear  wheel (66).  The heavy champered edges of the   brackets   must   face   toward   the center   of   the   gear   wheel.      Position spring support (58), install lockwashers    (57)    and    screws    (56). Hand tighten screws (56) at this time. CAUTION The  distance  between  the  spring  plates  on  the  spring support  (58)  and  the  camshaft  must  be  equal  on  both sides of  the  camshaft  before  screws  (56)  are  tightened. See Figure 6-28. (c) Tighten  screws  (56).    Torque  screws (56) to 21 lb-ft (35 Nm). (d) Place  shim  (34)  in  inner  spring  plate (53),  using  a  light  grease  attach  ball (55)  to  inner  spring  plate  (53).    Place the inner spring plate over one end of spring   (52).      Using   care,   insert   the open  end  of  the  spring  into  the  outer spring    plate    (58)    and    press    spring assembly  into  recess  in  weights  (60) until   the   ball   (55)   snaps   into   place. Repeat process for other side. NOTE There should be no tension on governor springs; weights should  move  freely  and  should  have  free  movement  of 1.0  -  1.5  mm  before  spring  tension  is  noted.    Adjust move-ment  of  weights  by  use  of  shims  (54)  to  obtain correct amount of movement (see Figure 6-28). (16)   Install governor and cam (66) into crankcase.    Remove  clamp  (tool  No.    15, Figure 2-1) hold-ing cam followers (tappets) away from cam shaft. CAUTION Oil pump (53) must have free movement after installation. NOTE Make  sure  gear  wheel  (21)  on  crankshaft  and  oil  pump gear  wheel  (52)  mesh  correctly  when  crankshaft  gear wheel (21) is installed. (17)   Figure  8-30,  Sheet  4  of  10.    Using  screws (48,  50),  lock  washers  (47,  49)  attach  oil pump  (53)  to  crankcase.    Attach  oil  pump gear wheel (52) to oil pump shaft using nut (51).    Insert  key  (40)  on  crankshaft.    Heat gear wheel (21) to 1000C (2100), line gear wheel   up   with   key   (40)   and   knock   gear wheel (21) onto crank-shaft. (18)   Figure 8-30, Sheet 5 of 10.  Heat governor hous-ing  (9)  to  800C  (1750F)  and  press  in ball bear-ing (11).  Install oil seal (1 la) and oil   seal   (11   b)   in   governor   housing   (9). Attach    gasket    (12).        Prior    to    mounting governor    housing,    install    tool    No.        31, bushing    for    mounting    governor    housing (crankshaft)  and  tool  No.    32,  bushing  for mounting     governor     housing     (camshaft). Insert  guide  pin  (10)  and  install  governor housing (9) to crankcase (32). (19)   Install  pins  (20a,  Figure  8-30,  Sheet  4  of 10)  in  end  of  crankshaft.    Fit  sheave  (20) and    attach    sheave    to    crankshaft    using lockwasher  (19)  and  screw  (18).    Torque screw (18) to 88 lb-ft (120 Nm). (20)   Figure  8-30,  Sheet  2  of  10.    Using  screws (37)   attach   crank   handle   support   (38)   to governor housing. (21)   Figure  8-30,  Sheet  6  of  10.    Using  screws (72)  and  lock  washers  (73)  attach  gasket (75)   and   fuel   feed   pump   cover   (74)   to crankcase.    Attach  gasket  (71)  and  large side   cover   (70)   to   crank-case   using   lock washers (69) and screws (68). CAUTION Oil holes in rod bearings and connecting rod must be in alignment. (22)   Figure 8-30, Sheet 4 of 10.  Press top end rod   bearing   (16)   into   rod   (17).      Position bearings  (15)  in  rod  can  and  rod.    Insert rods   (17)   into   crankcase   and   secure   to crankshaft  and  secure  to  crankshaft  using screws (14).  Torque screws (14) to 55 Ib-ft (75 Nm). 6-47
