Modified Assembly Procedure:
SCXT225 MIMA/ITW (Wrapper Units)
1. All assembly procedures for standard SCXT225 should be
followed except for the following changes in shimming of
output bearing.
2. New output bearing shimming procedures:
a. Place output bearing cup in left half of housing.
Ensure the bearing cup is correctly seated.
b. Position output hub seal carrier (without shims) and
install two carrier screws diametrically opposed.
c. Torque each screw to 50 in.-lb. Rotate the output hub to
roll in the bearings, then torque each screw to 100 in.-
lb. Rotate the output hub again to roll in the bearings.
d. Seat output bearings by tapping the seal carrier with
a hammer; turning the output hub again to further
roll in the bearings. Torque carrier bolts again to 100
in.-lb. Repeat this process of hammering, turning the
output hub, and torquing to 100 in.-lb. until bearings
are completely seated (3-4 seatings may be required).
e. With a feeler or taper gauge, measure the gap between
the housing and the carrier, clockwise from and next to
each screw.
f. To determine the required shim pack thickness,
subtract 0.010 in. from the average of the two gauge
readings (Pack Thickness = Gauge Average - 0.010 in.)
g. Remove the output hub seal carrier and install the
required shims (shim pack thickness should be
inspected with a 0-1” micrometer). Note: Total shim
thickness per carrier should not include more than
0.009” plastic shims. All other shims should be metal,
and each plastic shim should be inserted between two
metal shims.
h. Continue with normal assembly procedure from this
point. (Carrier bolt torque should be 360 in.-lb.)
