TM 5-3810-300-24 & P2
The hand rolled pattern shown (gears unloaded), will result in a pattern centered in the length of the tooth when the gears
are under load shown below. The loaded pattern will be almost full length and the top of pattern will approach the top of
the gear tooth.
The pattern on the coast side of teeth will appear the
same width-as the drive side shown; however, the
overall length will be centered between the toe and heel
of gear tooth.
SATISFACTORY TOOTH CONTACT
Set used hypoid gear to have the tooth contacts to match wear patterns. Hand rolled patterns of used gears will be
smaller in area and should be at the toe end of wear patterns.
A high contact indicates pinion is too far out. Set the
pinion to the correct depth by removing shims under the
pinion cage. Slight outward movement of hypoid gear
may be necessary to maintain correct backlash.
