CLUTCH
The amount of eccentricity of the dowel
will
pro-
duce a total indicator reading change of double the
dowel eccentricity, therefore, a pair of dowels with
the nearest to Y2 of the total indicator runout of the
bore. For runout (total indicator reading) of .012"
through .020", use a .007" dowel (P/N 1736347), .022"
through .034", use .014" dowel (P/N 1736348), and
.036" through .052", use .021" dowel (P/N 1736353)
(4) Install both dowels with the slots parallel and
aligned in the direction to correct the bore runout.
(Slot indicates the direction
of maximum dowel ec-
centricity.) Both dowels must be inserted into engine
block, up to off-set shoulder.

Install and tighten clutch housing bolts to 50
foot-pounds
(7/1s").
Remount dial indicator and recheck
bore runout. Small corrections can be made by re-
moving clutch housing
(if
necessary) and turning dow-
els with a screw driver to shift the housing and bring
bore within limits.
Face Runout
(1) Relocate dial indicator (Fig. 14). Rotate the
fly-
wheel, using Tool C-771. If the total indicator reading
is greater than .006" note the amount
of the total in-
dicator reading and the location of the lowest indi-
cator reading (Le., the point where the indicator arm
or follower is extended the furthest).
(2) To correct excessive runout, place the proper
thickness of shim stock between the clutch housing
and the engine block or between the transmission and
clutch housing. After re-checking face runout, tighten
housing bolts to 50 foot-pounds. Install transmission.

STEAM CLEANING PRECAUTIONS
The clutch housing, being ventilated, steam vapor
condenses and moisture settles on the internal mov-
ing parts of clutch mechanism. The facings of the disc
will absorb moisture and under the force exerted by
the pressure plate, will bond the facings to flywheel
and/or, the pressure plate,
if
the car is allowed to
stand for some time before use. If this condition oc-
curs, it will necessitate complete replacement of disc,
pressure plate, flywheel and/or, driving plate.
Imme-
diately after the cleaning operation, start engine and
"slip the clutch" in order to dry off the disc assembly,
pressure plate, and/or flywheel.
