Remove the bearings (items  and ) from the planetary gear ().
Skip to step 8 if the gear does not need replaced. If the gear needs
replaced, continue to the next step.
Remove the internal retaining rings ( and ) from the planet gear ().
Install the internal retaining rings ( and ) in the new planet gear ().
Install the bearings ( and ) into the planet gear (). Use a bench-top press as
required to push the bearings into the planet gear.
Make sure the bearings are pressed into the planet gear to the depth
illustrated in Figure 5-8. If the bearings do not meet the depth
requirements shown, the c-clip will not lock onto the bearing pin.
Put the planetary gear () on the bearing pin () Make sure the wave spring () is
