TRUCK SERVICE MANUAL TM 5-4210-230-14&P-1 Fig.  9 Staking Pinion Straddle Bearing It is suggested that for locating punch' positions for   staking,   the   end   of   the   pinion   be   painted   with Prussian Blue and a circle be scribed on end of pinion about 3.17 mm (1/8") in from the pinion circumference. When   staking   the   bearings   be   careful   to   make   the depth   of   the   indentations   or   stake   points   uniform, otherwise  bearing  may  be  damaged.    Deep  punch  or stake   marks   are   not   necessary.      Apply   the   staking operation  at  opposite  sides  of  the  pinion  end  until  all stake points are obtained.  Where special staking tools are available, they can be used, otherwise the use of a blunt or round nosed punch is satisfactory. 3. If bearing cups (7) have been replaced, press new cups firmly against shoulders of pinion cage (10). 4. Prelubricate the bearings with gear lubricant. 5. Position  spacer  (8)  on  pinion  shaft  and  against  rear thrust bearing. 6. Insert pinion and rear thrust bearing (6) in pinion cage. 7. Mount  pinion  and  cage  in  arbor  press  and  place  pre- lubricated   front   thrust   bearing   (6)   on   pinion   shaft.      Press bearing firmly and squarely against spacer. Pinion Bearing Preload Pinion bearing preload is established by selecting  the  correct  size  spacer  (8)  located  between the two pinion thrust bearings and tightening pinion end nut to the specified torque (see "TORQUE CHART"). 8. Temporarily assembly the pinion, cage and flange    assembly,    less    oil    seal    and    retainer.    Clamp    the assembly in a vise to hold the companion flange.  Tighten end nut to specified torque. 9. The pinion cage should be rotated while tightening the pinion to seat and align the bearings.  Rotation of the pinion is important.  Otherwise  a  false  condition  of  bearing  load  could exist.  The bearing rollers must be seated against the face of the bearing cone (Fig.  10). Fig.  10  Pinion Bearing Roller Position 10. To measure bearing preload, wrap a strong cord or soft wire about the pinion cage and attach end to spring scale (Fig. 11).  Read  scale  only  while  cage  is  rotating.    Compare  this scale reading with the figure shown in "SPECIFICATIONS". Fig.  11  Measuring Pinion Bearing Preload 11. When preload does not agree with "SPECIFICATIONS",    bearing    load    may    be    increased    by installing  a  thinner  spacer  or  decreased  by  using  a  thicker spacer.  Determine spacer thickness using a micrometer (Fig. 12) and make a new selection accordingly.  Closer adjustment may   be   obtained   by   working   spacer   to   desired   thickness, using emery cloth on a flat surface.
