3. Thread a ring bolt into each of the two
tapped holes in the thrust bearing.
4. Attach a suitable lifting device to the ring
bolts and carefully lift the thrust bearing
over the main shaft. Replace the two
eccentric bushing oil temperature RTDs, if
necessary.
5. Check the replacement thrust bearing and
the thrust bearing shims that are to be added
to be sure there are no burrs or upset edges
that would prevent the bearing or shims
from lying flat against the main frame with
full surface contact.

Replacement
6. Refer to
Adjusting Gear Backlash for Wear
in
Section 5
, to determine the correct
amount of shims to be installed. Any
additional shims to be added are placed on
the top of the existing shim stack. If a new
thrust bearing is to be installed, remove the
ring bolts from the old bearing and install
them in the new bearing. Lower the thrust
bearing in place making sure that all holes
are properly aligned with the holes in the
main frame hub. Make sure bearing is fully
and squarely seated on the shims.
7. MP800 and MP1000 models:
a. Place a spring washer into each
counterbored hole in the thrust bearing
with the incline up. Refer to Figure 3-4.
b. Insert and turn all the capscrews until
they all are snug against the spring
washers.
c. Alternately tighten each capscrew a
small amount until a torque value of
470 Nm (345 ft. lbs.) is obtained on each
capscrew.
