TRUCK SERVICE MANUAL
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
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.
