with the fork.
NOTE: BE SURE THE SPRINGS HAVE LATERAL
FREEDOM. When installing the transmission, DO
NOT LUBRICATE the pilot shaft or the clutch
splines. This area must be kept DRY.
(7)
Install the transmission by guiding into position
with C-730 pilot studs. Care should be taken in order
not to bend the clutch disc by allowing the transmis-
sion to hang. Support the transmission with a suit-
able jack, then slide into place and secure with bolts.
(8) Adjust clutch linkage. Refer to page 2.
SERVICING THE TORQUE SHAFT
PIVOT BEARINGS
(1) Unhook the clutch release fork return spring
from the bracket and fork (Figs. 5,6 or 7).
(2) Disconnect the clutch release fork and rod from
the torque shaft.
(3) Remove the clutch release rod spring clip from
the release rod and disconnect rod from torque shaft.
(4) Remove the torque tube bracket screws from
the side shield and the pivot bolt/or bolts from the
engine block and remove torque tube assembly.
(5)
Remove spring retainer from end of torque
tube and pull out the two pivot bearings. Repeat pro-
cedure at other end of tube.
(6) Clean all old grease from within the tube and
reassemble. Lubricate with Multi-Mileage Lubricant
and reassemble on the vehicle.
CLUTCH HOUSING ALIGNMENT
When performing adjustments or repairs that in-
volve removing the clutch housing, it will be neces-
sary to align the face of the housing parallel with that
of the block when assembling.
Bore Runout
follows:
To correctly align the clutch housing, proceed as
(1) Mount Tool C-870 with C-435 Dial Indicator on

flywheel (Fig. 11).
(2) With flywheel turning Tool C-771, crank engine
while noting dial indicator needle deflection. Out-of-
round of bore must not exceed .008 inch (maximum)
total indicator reading.
If bore runout is in excess of .008 inch total indi-
cator reading proceed with correction as follows:
To illustrate the recommended correction proce-
dure, assume that the total indicator reading is .020
inch, in a direction which approximates 2 o'clock on
engine block (Fig. 12 or 13 depending on model).

In this case, the housing is off crankshaft centerline
.010 inch (one-half total indicator reading) which is
.006 inch greater than the allowable limit of .004 (one-
half total indicator reading).
In the case under consideration, use of the .007
inch offset dowels (pair) will bring the runout well
within the allowable limits of .008 inch or .008 inch
minus .007 inch (offset dowels) equals .001 inch run-
out. Dowels must be used in pairs
(same part number).
(3)
To
install the dowel pins (pair), remove clutch
housing (after disconnecting and removing starting
motor). Remove dowel pins from engine block. Select
eccentric dowels (pair) which are available with the
following amount of offset: .007" (No. 1736347), .014"
(No.
1736348), .021"
(No.
1736353).
