Refer to par. 72 for general inspec-
tion and repair recommendations. Repair
and rebuild points of measurements for
fits,
clearances and wear limits are
indicated by small, lower case letter in

101. ASSEMBLY (fig. 373, fold-out 2)
a . Install new replacement inserts
137, 140, 112, 113 and 122 from 0.005-inch
to one turn below the housing surface.
b. If 1-inch plug 114 was removed,
install it. Torque plug 114 to 70-90 pound-
feet. If 1/8-inch plug(s) 115, 116 or 131
were removed, install them. Torque plugs
115, 116 and 131 to 50-60 pound-inches. If
l/4-inch plug(s) 117 or 123 were re-
moved, install them. Torque plugs 117 and
123 to 96-120 pound-inches. If 1/16- inch
plug 9 was removed, install it. Torque
plug 9 to 35-50 pound-inches.
c. Install sleeves 119, 120, 134 and
136, pressing them until they are firmly
seated against the housing.
d. If input transfer drive gear bearing
support sleeve 139 was removed, install
new replacement as follows:
(1) Mark the locations of the
three original pin holes, in the sleeve bore,
on the bolt hole circle of the housing.
(2) The pin holes to be drilled for
the new sleeve should be located 60
degrees
clockwise or counterclockwise
from the original pin holes. The two
alternate pin locations are indicated by
the broken line in fig. 151.
Note. Be sure that the pin holes
to be drilled do not interfere with
the oil holes located on the knit
hole circle (fig. 151).
(3) Install sleeve 139 (fig. 373,
fold-out 2), pressing it flush with the hous-
ing outer surface.
(4) Using a 0.1855-0.1875 drill,
drill a hole 0.410 to 0.470-inch deep at one
of the alternate locations chosen. This
hole should be 0.250-inch inward from the
cover mounting surface and at a 30 degree
angle to the cover mounting surface. Ref-
er to figure 151.
(5) Drill the remaining two dowel
pin holes, spacing them 120 degrees apart.
(6) Install the three pins (fig.
151), driving them 0.005 to 0.015-inch be-
low the sleeve surface.
(7) Line bore sleeve 139 (fig. 373,
fold-out 2) to 7.0864-7.0876 inches diam-
eter, with a finish of 100 RMS (fig. 151).
e . Install the power take-off cover
(fig. 150) and gasket. Secure the cover
with ten 3/8-24 x 1-1/4 bolts and lock
washers. Torque the bolts to 33-40 pound-
