5.
Take out the bearing spacer and take out the
remaining retaining ring.
6.
Place the shaft front side down on the
press to remove the internal race of the
needle bearing. Support only the internal
race.
IMPORTANT: Use similar diameter rings or
“V” blocks of softer metal to avoid damage
to the shaft. The shaft needs to have
enough clearance to move out without
scratching.
7.
Press at the center of the shaft until the
internal race slides out.
IMPORTANT: Use a soft metal between
the piston and the shaft to avoid marking
it. The shaft has to be held to avoid falling
down.
