1. Remove harmonic balancer pulley/balancer,
oil pan, water pump pulley/water pump
and timing cover.
2. Remove oil pan, timing cover and water
pump gaskets. Clean engine block mating
surface area.
3. Install horseshoe timing cover gasket
onto engine block*.
4. Install crankshaft oil seal into cam cover.
Support cover at seal area and insert new
seal so opened end is toward the inside of
cam cover. Drive seal into position.
5. Install retainer ring onto dowel pins on
front of engine block. Place oval quick
change timing cover gasket and timing
cover onto retainer ring. Install mounting
bolts into engine block hand tight. Do
not tighten front cover mounting bolts
at this time.
6. Install oil pan*. A thin (.250"h) and thick
(.380"h) front oil pan seal is supplied.
The thin seal fits engines from 1955-74
and thick seal fits engines from 1975-91
using a stock oil pan.
For aftermarket oil pans, check with the
oil pan manufacturer to confirm the
correct front seal thickness to be used
with their oil pan.
7. To reduce the possibility of a front cover
seal leak it is advisable to install the
harmonic balancer before tightening the
front cover bolts. This procedure allows
the front cover & oil seal to center itself
to the crankshaft.
8. Tighten front cover mounting bolts to
proper torque specification (refer to
vehicle manufacturer service manual
for correct fastener torque specification).
Do not over-tighten mounting bolts.
9. Install water pump* and engine pulleys.
10. Start engine and check for leaks to
complete installation.
