13. Inspect front oil pan gasket and replace if
damaged. If new gasket Is Installed, it should be
cemented to oil pan.
14. If new fuel pump eccentric and bushing are to
be installed, remove camshaft sprocket retainer bolt
and retaining washer and remove the eccentric and
bushing. Place fuel pump bushing over eccentric
with rolled flange toward camshaft sprocket (Fig.
6-95).
NOTE: Bushing retaining flange should be between
eccentric and sprocket for retention of bushing in
operation.
Install bushing and eccentric, indexing tang on ec-
centric with keyway cutout in camshaft sprocket.
Insert retaining screw with retainer washer and
tighten securely.
15. Position new timing chain cover gasket over
studs and dowels against block.
16. Transfer water pump to new timing chain
cover if new cover is to be installed.
17. Install new O-ring seal in water recircula-
tion passage of intake manifold.
18. Position timing chain cover on engine index-
ing over dowels, install bolts and nuts and tighten
securely.
19. Install four oil-pan-to-timing-chain-cover
screws and tighten to 12 lb. ft. torque.
20. Install harmonic balancer, retainer bolt with
retainer, and tighten to 160 lb. ft. torque.

TIMING CHAIN AND SPROCKETS-
REMOVE AND REPLACE
1. Remove timing chain cover, making certain
O-ring seal and hollow dowels are retained for in-
stallation at assembly.
2. Remove fuel pump eccentric, bushing and tim-
ing chain cover oil seal.
3. Align timing marks to simplify proper position-
ing of sprockets during reassembly (Fig. 6-96).
4. Slide timing chain and sprockets off ends of
crankshaft and camshaft.
5. Install new timing chain and/or sprockets, mak-
ing sure marks on timing sprockets are aligned
exactly on a straight line passing through the shaft
centers (Fig. 6-96). Camshaft should extend through
sprocket so that hole in fuel pump eccentric will
locate on shaft.
