TM5-4210-229-14&P 6-15. TRANSMISSION REPAIR (Continued). (h)   Using a lathe with a four jaw chuck, mount the carrier with surface A facing the chuck. Insert the six fabricated dummy pins (284) into the pinion pin holes. Adjust the chuck, centering  the  carrier  based  on  surface  B and the runout of the dummy pins (284). (i)    Total   runout   of   the   bushing   (285)   after boring  must  not  exceed  0.002  inch  (0.05 mm). NOTE The hydraulic press, used with planetary rebuilding set, should have a ten ton (9000 kg)capacity, an adjustable press     bed     of     25     inches     (64     cm) minimum     opening     and     a     pressure gauge  to  assist  in  determining  proper installation   and   staking   of   the   pinion pins. (j)    Using a drill that is slightly smaller than the pinion   pin   (286)   diameter,   drill   into   the swaged   ends   of   the   pins   (only   one   end required).  Do  not  drill  into  the  carrier.  The rear ends of all pinion pins except those in the  center  carrier  assembly  will  be  drilled. Drill the front ends of the center assembly pins. (k)   Place   press   fixture   in   a   hydraulic   press. Select  the  proper  spacer  and  adapter,  if required,    from    the    special    tool    chart. Position these parts (if used) to support the carrier   assembly   (drilled   ends   of   pinion pins upward) solidly on the press fixture. (I)    Install   pin   remover   into   the   ram   of   the press  fixture.  Press  the  pinion  pins  (286) from the carrier assembly (287). (m)  Remove  the  pinion  groups,  consisting  of pinions   (288),   bearings   (289)   and   thrust washers (290). (n)   Lubricate   needle   rollers   (289)   and   thrust washers     (290)     with     oil-soluble     grease (Appendix  D,  Item  21)  before  assembling the   pinion   groups.   Assemble   all   of   the pinion    groups    for    the    carrier    assembly (287). Each group is assembled by inserting-the proper loading pin into the bore   of   the   pinion,   installing   the   needle roller    bearings    around    the    loading    pin, installing a steel thrust washer at each end of the pinion, and installing a bronze thrust washer onto each steel thrust washer. (o)   Position   the   carrier   assembly   (287)   rear end   upward   (except   the   center   carrier). Install  all  pinion  groups  into  the  planetary carrier,  aligning  the  loading  pins  with  the pin bores in the carrier. 6-76
