9. Remove both the inner and outer bearing cones,
planetary hub assembly, and TRS toric ring metal
face seal half from the spindle. Wrap the inner and
outer bearing cones to prevent contamination and set
a
side for later cleaning, inspection and re-assembly.
CAUTION
Care should be taken to store the (2) halves of the
face seal to protect them from damage and saved
for reassembly later when required.
10. Remove the loose TRS face seal from the spin-
dle. Please use the face seal tool as shown in the
special tools section during later reassembly. If
removed, store the (2) face seal halves together
and wrapped in a manner to prevent contamina-
tion or damage to the metal seal surfaces.
11. If required, use a suitable bearing cup puller to
remove both the cups from the planetary hub
assembly. Wrap both the bearing cups to prevent
contamination. If bearing cups are not to be
removed, please proceed to the next step.
12. Remove the inner bearing spacer from the
spindle only if required. This spacer has had
Loctite 680 or equivalent applied at original
production assembly and should not be removed
unless damaged.
WARNING
Observe all warnings and cautions provided by
the press manufacturer to avoid damage to
components and serious personal injury.
NOTE:
Should the planetary spider and gearsets
need to be disassembled, please go to the specific
section for disassembly required.
13. Remove the planetary ring gear and O-ring from
the spindle flange, if required, separate the ring
gear and O-ring from the spindle.Set aside these
components for later inspection and reassembly.

Disassembly of the Planetary Spider
Assembly
1
. Place the planetary spider assembly safely in a
vertical position with the planetary gears facing
upwards. Figure 2.16.
NOTE: Using a grease pencil, mark each planet
pinion shaft/planetary pinion gear with same number
to identify which pinion shaft and gear were originally
pre-assembled together for later re-assembly.
2. Mark each planet pinion shaft and its planetary pin-
ion gear with matching numbers.
3. Remove the snap ring from the groove near end
of each planetary pinion shaft.
4. Remove the inner washer from each planetary
pinion shaft. During removal, mark the washer
with the pinion shaft number to retain with same
original planetary shaft/gear assembly or place in
numbered plastic bags.
NOTE: The (33) needle rollers/planetary gear
assembly should also be placed in separate bags as
removed from each planetary pinion /shaft assembly
and marked to keep the rollers with the same planet
gear/shaft for later inspection and re-assembly.
5.
Carefully lift the planet pinion gear
, full complement
of needle rollers, and outer thrust washer as an
assembly. It may be easier to slide a thin shim
stock under the thrust washer or planetary pinion
gear as it is lifted to capture all the loose needle
rollers. The needle rollers should be retained or
replaced, if required, as a set for each planetary
pinion and pinion shaft.
6. Using the grease pencil, label the outer washer
with the same number as marked for the planetary
gear/needle roller assembly
.
NOTE: Repeat above for each planet gear to be
removed.
