SERVICE MANUAL Install  spring  washer,  if  applicable,  to  the  drive gear  and  shaft  (5)  with  the  convex  surface  facing  the drive  gear.    Install  parking  cam  (8)  on  drive  gear  and shaft  assembly(5).    Face  dotted  end  of  cam  in  same direction as was noted in "Disassembly." Place drive gear and shaft assembly (5) in drive end  housing  bushing  bore.    Install  spacer  washer  and crank arm.  Install nut and tighten to a torque of 55-60 in. lbs.  Be certain to support crank arm while tightening nut to prevent stripping gear teeth (see "Disassembly"). Install   gasket   (10)   and   parking   switch   contact plate  (9).    Position  drive  end  housing  cover  (11)  on  the drive end housing (3) and insert retaining screws.  Install mounting bracket (2) on drive end housing (3). TESTING Before  installing  the  windshield  wiper  motor  on the vehicle, check the operation of the unit as follows: Be  certain  that  the  required  crank  arm  or  drive plate  and  spacing  washers  are  assembled  to  the  drive shaft when testing the motor.

Yellow Temporarily   connect   either   terminal   of   a   fully charged   battery   to   the   motor   housing.      Connect   the remaining  battery  terminal  and  the  wiper  motor  wiring harness   to   a   control   switch   as   follows:      Connect   red cable to "A" terminal,  green cable to "F" terminal, black cable to "P" terminal, and remaining battery cable to "B" terminal. The    wiper    motor    should    meet    specifications when    operated    through    control    switch.        If    not,    tap commutator  end  frame  lightly  with  a  rawhide  mallet  to make  certain  that  the  armature  is  aligned.    If  unit  still does   not   meet   specifications,   it   will   be   necessary   to disassemble the unit to locate the trouble. INSTALLATION Place  wiper  motor  in  position  and   insert   bolts holding  motor  and  bracket  assembly  to  cowl.    Connect wiper  arm  Linkage.    Connect  wiring  harness  to  control switch. ADJUSTING AUTOMATIC PARKING The    wiper    blade    parking    position    should    be adjusted after the motor has been installed in the vehicle. Adjust parking as follows: Operate   motor   through   control   switch.      When switch is turned to "OFF" position, motor should stop with Linkage fully extended.  If necessary, this position can be obtained  by  adjusting  the  parking  stud  which  protrudes through  the  drive  end  housing  cover.  Install  the  wiper arm  and  blade  to  the  wiper  arm  shaft  assembly  so  that the blade is in the desired parking position.  Operate the wiper   and   note   the   automatic   parking   position   of   the blades  when  the  unit  is  turned  off.    If  the  blades  do  not now park in the required position, readjust by moving the parking stud. LUBRICATION During  reassembly,  apply  two  or  three  drops  of SAE-10 oil to the armature shaft bushing felts. Place 1/3 ounce of Lubri-Plate Aero Lubricant or its  equivalent  in  the  drive  end  housing  worm  cavity.  No lubricant    should    be    placed    between    the    gear    and housing.    If  the  housing  has  two  bushings  in  the  crank arm shaft bore, fill the space between the bushings with the above specified lubricant. Fill   groove   in   gear   and   shaft   assembly   with lubricant,  if  applicable.    Apply  a  thin  film  of  lubricant  to the  cam,  spring  washer  and  spacing  washer.    Apply  a thin  film  of  Lubri-Plate  No.    10  or  its  equivalent  to  the connecting link bushings. Fill the space between the bushings in the inner spacer with Lubri-Plate Aero Lubricant or its equivalent. CTS-4056-Chapter II PRINTED IN UNITED STATES OF AMERICA Page 5
