arrow and its center line is parallel to
the center line of the face runout
arrow.

Determine the amount of the
face runout on the B arrow scale.
19.
The value of the circular line
beneath the amount of face runout
will be the desired reading. If the
reading is in excess of 0.014 inch the
housing alignment is unacceptable.

ENGINE IN VEHICLE
Since any change in face alignment
will change bore alignment, it may be
possible to correct bore alignment by
changing face alignment. Face align-
ment can be changed by shimming be-
tween the flywheel housing and en-
gine.
Fig. 4 shows the type of shim
which can be fabricated.
Not more than 0.010 inch thickness
shims may be used between the fly-
wheel housing and engine. If a 0.010-
inch shim will not bring face and bore
alignment within limits, replace the
flywheel housing.
The shim required is one half the
maximum (—) indicator reading, and
should be located at the point of max-
imum minus (—) indicator reading.
If both the bore and face alignment
are out of limits, shim between the
flywheel housing and engine to bring
face alignment within limits. Check
the bore alignment.
If the bore alignment is out of lim-
its and the face alignment is within
limits,
shim the flywheel housing to
the limit of face misalignment and
check the bore alignment. If it is not
within limits, replace the housing.
ENGINE OUT OF VEHICLE
The same procedure to correct
alignment may be used with the en-
gine out of the vehicle or in the vehi-
cle,
up to the point of replacing the
flywheel housing. If the bore align-
ment cannot be brought within limits
by shimming, follow this procedure:
dure:
1.
Remove the flywheel housing
from the engine and remove the dowel
pins.
Install the flywheel housing and
tighten the attaching bolts.
2.
Install the dial indicator (Fig. 1).
Check the face alignment, and shim as

required to bring face alignment with-
in limits.
3.
Position the indicator to check
the bore alignment. If the bore align-
ment is not within limits, reduce the
tension on the flywheel housing at-
taching bolts so that the housing can
be moved by striking it with a lead
hammer or a block of wood and a
steel hammer.
4.
The lateral alignment should be
brought within limits so that an indi-
cator reading is within limits between
the 9 o'clock and the 3 o'clock posi-
tions on the bore circle. When the lat-
eral alignment is within limits the
housing usually can be moved straight
up or down without disturbing the lat-
eral alignment. When alignment is
within limits, torque the housing bolts
and recheck bore alignment.
5.
If the flywheel housing cannot be
moved enough to bring the alignment
within limits, mark the holes restrict-
ing movement, and then remove the
housing and drill the marked bolt
holes 1/32 inch larger.
6. When the flywheel housing bore
alignment is within limits and the at-
taching bolts are at normal torque,

hand ream the dowel pin holes 1/32
inch larger. Use a straight reamer and
ream from the flywheel housing side.
Oversize dowel pins can be made from
drill rod stock.
7.
Remove the flywheel housing
and then install the oversize dowel
pins in the cylinder block. Complete
the assembly in the usual way.
8. Recheck the flywheel housing
with the Dia-L-lgner gauge to make
sure that the housing is within the spe-
cified limits.procarmanuals.com
