3. Locate the high spot on the swing bearing. This will
be marked by blue paint and two X’s on the bearing
teeth.
4. Place the new bearing onto the frame orienting the
high spot as close as possible to where the swing
drive gear will be.
5. Once the bearing is positioned on the frame, start
the outer race bolts by hand until they are all
installed.
6. Tighten all the outer race bearing bolts until snug
and then torque them according to the torquing pro-
cedures in this section.
7. Install grease fittings into the bearing and also install
two pins to facilitate turning the bearing by hand and
for alignment of the turntable.
8. Using the pins, turn the bearing slowly by hand
while an assistant applies grease to the fitting. Apply
grease until the bearing is adequately greased
around the entire circumference of the bearing.
9. Place the swivel back into position and secure in
place with the mounting hardware.
10. Line up the two grease holes in the bearing perpen-
dicular to the chassis and install the remote grease
lines.

of the turntable. If necessary, run a tap through the
swing drive mounting holes to clean the threads.
