4. Repeat operation in bearing cap. An arbor
press
or vise will provide the best means of
forcing the packing into place and holding it while
trimming.

Removal of Timing Chain and
Sprockets
1. Remove water pump, Section 13, Note 18.
2, Remove engine oil pan, Note 14.
3. Remove crankshaft pulley and harmonic hal
ancer assembly.
4. Remove engine front cover,
5. Remove two cap screws and lock washers
which hold sprocket to camshaft,
6.

Removal of Camshaft
1. Remove hood lock plate support.
2. Remove Air Conditioning condenser as ex
plained in Section 16a, Note 21, if car is so equipped.
3. Remove radiator core, Section 13, Note 16-a.
checked for proper alignment. To make this in
spection, the camshaft should be placed on "Vee"
blocks at the front and rear bearing journals, or
on centers, on a surface plate. A dial indicator
should be mounted so that it is directly over the
centerline of the camshaft with the pointer touching
the shaft.
Set the dial indicator to read zero on the heel
of No. 1 cam lobe and thgn chcck the heel of each
cam lobe for a full 180
of rotation. If any dis
crepancy greater than .0015
total indicator read
ing on any particular cam heel is discovered, the
camshaft should be replaced.
The runout of each of the bearing journals should
also be checked. If more than .0015" total indicator
reading
runout
is discovered,
the camshaft is
sprung out of alignment and should be replaced.

Removal of Camshaft Bearings
1. Install puller collet of Camshaft Bearing Re
moving and Installing Tool No. J-3063 in No. 5
bearing, Fig. 10-30.
NOTE:
Install a rubber band over both collet
fingers next to thumb screw,
to hold fingers
while installing collet.
2. Tighten thumb screw and check to see that
fingers are securely behind No. 5 bearing.
4, Remove timing chain and sprockets, as ex
plained in Note 29.
3. Install arbors "B", "C", and
Nos. 1, 2, and 3, respectively with
of arbors toward rear of block.
"E" in bearing
large diameter
5. Remove valve lifters, Note 10
6. Remove distrthutor,
Section 11, Note 12a.
7. Slide camshaft forward carefully until it is
out of engine.
CAUTION:
Extreme care should be exercised
to keep the cam lobes from scratching the cam
shaft bushings.

Checking Camshaft
The camshaft, on all 1954-Series cars, is made
of cast iron and must be handled with particular
care to avoid damage.
If the shaft is accidentally dropped, it may be
sprung out of alignment, or the cam lobe surfaces
may be damaged enough to cause erratic valve
action or worn lifters and result in unsatisfactory
engine performance.
4. Slide shaft through all three arbors and through
No. 4
bearing.
5. Holding pilot "0" which is used as an arbor
in the removal operation behind No. 4 bearing,
slide shaft through pilot "D".
CAUTION:
Be sure sharp corner on pilot "D"
outside
diameter
is
toward No.
4
bearing.
6. Thread shaft into puller collet in No.5 bearing.
7. Slide bridge over front of shaft, with legs of
bridge toward front face of block.
B. Slide flat washer on front end of shaft and
install puller nut loosely.
9. Place a 3/4" open-end wrench over section
of shaft on flats, which are between bridge and
block. This keeps shaft from turning during the
pulling operation.
Whenever the camshaft is removed, it should be
