the tapped hole in the end of the pin in conjunction
with a slide hammer or similar tool to remove them.
3. Remove the output planet gear, thrust washer, and
tanged washer out of each gear “window” of the
spindle.
NOTE: The output planet gears are a very similar size to the
input planet gears, tag or label the planet gears to
avoid confusion.

ring.
5. Remove the shaft ball bearing from the center bore.
6. Press out the motor shaft seal from the center bore.
