C A UTI 0 N: The notch in edge of bearing is used
to properly position the bearing with respect to oil
holes, when it is installed. When bearings are
installed in production, notches all face front
except the one in rear bearing.
In service it is necessary to install bearings with
notch facing the rear.
5. Position replacer adapter 5-6173-3, with bearing in
position against shoulder, against rear of hole in which
bearing is to be installed (Fig. 6A5-31). Index mark on
shoulder of replacer must point down (toward crankshaft
side) to
position bearing.

6. Insert shaft with indexing collar, thrust washer, and
nut through remover, pilot and replacer adapters. Index lug
on collar with ventilation hole in front of block (Fig. 6A5-29).
7. Slip key 5-6 173-5 into notches in shaft behind replacer
adapter 5-6173-3 and tighten nut to start bearing into hole
(Fig. 6A5-30). Continue to tighten nut until bearing has been
pulled completely into its hole. When properly positioned, it
will be approximately flush with both sides of the transverse
member.
Rear bearing should be pulled in until front edge is flush
with block. This will leave shoulder at end of counter bore
for camshafi rear plug visible behind bearing.
8. Remove remover and replacer set 5-6173.
9. Visually observe that holes in bearing line up with
drillings in block.
10. Carefully remove all metal particles from block
surfaces and oil drillings.
CAMSHAFT
Replace
1. Coat inner diameters of all camshaft bearings with oil.
A. Coat camshaft lobes with E.O.S.
B. Carefully install camshaft.
C. Rotate camshaft through several revolutions to make
sure it is completely free.
If any tight spots are found, remove camshaft and very
carefully polish down the center journal slightly. If still not
free, polish the front and rear journals slightly.
If any particular bearing causes binding of the camshaft,
replace that bearing also.
Front center and rear center journals should not be
polished except to remove slight roughness or scratches.
Slight warpage of the camshafi is not harmful, provided the
journals are polished down until the camshafi rotates freely
in its bearings.
2. With camshaft properly seated, install camshaft thrust
plate and tighten bolts to 20 Ib. ft.
3. Install timing chain sprockets and timing chain,
making sure marks on sprockets are aligned properly. Refer
to Fig. 6A5-28.
4. Install fuel pump eccentric and bushing. Insert tang
on eccentric into hole in camshaft sprocket. Tighten camshaft
sprocket retaining bolt to 40 Ib. ft.
5. Install timing chain cover dowels and new gasket and
tighten bolts and nuts to 30 Ib. ft.
6. Insert four oil-pan-to-timing-chain-cover screws and
tighten to 12 Ib. ft.
7. Install fuel pump and tighten bolts to 25 Ib. ft.
8. Install harmonic balancer. Tighten bolt to 160 Ib. ft..
9. Coat base of lifters with E.O.S. Install hydraulic lifters
and push rods, making certain they are replaced in their
original positions.
10. Engage rocker arms on push rods and tighten rocker
arm ball retaining nuts to 20 Ib. ft.
1 1. Install push rod cover.
12. Install intake manifold and gasket. Tighten bolts to
40 Ib. ft..
NOTE: New O-ring seal must be installed between
intake manifold and timing chain cover before manifold
is securely positioned.
13. Install distributor, positioning rotor to fire number
one cylinder, and install distributor hold-down clamp.
(Distributor housing will be properly positioned when
vacuum advance unit is at right angles, facing R.H. side, to
centerline of crankshaft). Tighten clamp retaining screw to
30 Ib. ft. after ignition timing has been set.
14. Install crankcase ventilator outlet pipe and both
rocker arm covers and gaskets. Tighten cover bolts to 65 Ib.
in.
15. Install fan and pulleys.
16. Install radiator, tightening all bolts securely.
17. Install hood latch bracket and tighten bolts.
18. Connect carburetor linkage, fuel lines and
thermogage unit.
19. Connect all water hoses, vacuum hose and spark plug
wires.
20. Install carburetor air filter.
21. Refill cooling system and check for leaks.
