2.3.2.1 Disassembly
Remove the Ring Gear Retaining Ring #29 with a Slotted Screwdriver and
lift out the Ring Gear #30. If the Gear is tight in the Tee Housing #35/#55,
carefully pry it out with flat screwdrivers. Next, lift out the Tee Housing
Bevel Gear #31, Tee Housing Bearings #32, and Tee Housing Seals #33.
2.3.2.2 Tee Housing #35/#55
Inspect the Tee Housing #35/#55 for damage to the Tee Housing key way
that engages the Ring Gear #30. If the Ring Gear was difficult to remove,
check to see if the Tee Housing is out-of-round (as the result of an external
blow, such as dropping) where the Gear seats.
2.3.2.3 Bevel Gear #31
Inspect the Tee Housing Bevel Gear #31 for worn, damaged or
sharp/pointed teeth, and for damage to the key that engages the slot on the
Gearbox Nose #14.
2.3.2.4 Ring Gear #30
Inspect the Ring Gear #30 for worn, damaged or sharp/pointed teeth, and
for damage to the key that engages the slot on the Tee Housing #35/#55.
2.3.2.5 Tee Housing Bearing #32
Inspect the Tee Housing Bearings #32 and discard any that are broken,
cracked, or deeply scored. Clean any deposits from the Bearings and
check their fit in the Tee Housing Bearing Cups #34. While they should
turn freely in their Cups, the Tee Housing Bearings should be replaced if
the diameter of the
outside wall
is
less than 1.490"
to avoid shortening
the life of the Seals or Bevel Gears.
2.3.2.6 Tee Housing Seals #33
Examine the Seals for loss of spring tension (indicated by excessive dry
deposits of dirty or abrasive cleaning solution on the spring) or excessive
wear on the sealing lips (the sealing lip is worn to a smooth surface) and
replace as required. When installing the Seals, make sure that the spring
side of the Seal faces towards the Tee Housing Bearing Cup #34.
2.3.2.7 Tee Housing Bearing Cups #34
Clean any deposits from the Cups and examine for excessive wear. Light
scoring is acceptable, but the cups should be replaced if they are grooved
in the seal contact area or if the diameter of their
inside wall
is
greater
than 1.520"
. If the Bearing Cups require replacement, follow the
procedure given for the Nozzle Housing Cups #40/#60 in section 2.3.1.6.
