TRUCK SERVICE MANUAL
TM 5-4210-230-14&P-1
set, which, because the load is distributed over the teeth
within  the  proper  area,  will  deliver  all  the  long  service
built into it.
When checking paint impressions on gear teeth
of  an  axle  under  heavy  load,  the  impressions  usually
spread out somewhat longer than the patterns obtained
from  a  bench  test.    This  can  be  considered  as  normal.
Ring   gears,   when   mounted,   should   show   a   bearing
toward the toe or small end of the tooth, but never at the
heel  or  large  end.    The  reason  is  that  it  is  practically
impossible  to  make  gears  and  gear  mounting  so  rigid
that no deflection will occur when full torque is applied.
This deflection causes the bearing to approach the heel
of  the  tooth.    And  when  gears  are  adjusted  so  that  the
bearing  is  toward  the  heel  of  the  tooth,  it  results  in  a
concentration of load on the top corner of the heel, and
breakage will follow.
Loctite Plastic Gasket Material
On   those   axles   which   utilize   Loctite   Plastic
Gasket  material  in  place  of  the  more  common  gasket,
the plastic gasket material should be applied as follows:
1.   Thoroughly clean the mating surface to remove
foreign matter.
2.   Spread a thin, even coating on one surface. On
large or rough surface apply to both surfaces.
3.   Assemble parts.  Bolt mating parts together.
4.   Loctite   Plastic   Gasket   will   dry   in   four   to   six
hours  under  normal  temperatures.    If  it  is  not
possible   to   wait   the   four   to   six   hours,   apply
Locquic   Primer   Grade   T,   which   will   reduce
drying time required to approximately one hour.
This primer must be bought locally.
