1.
Determine oil pan part number; check high and low
capacity.
2.
Drain all oil from oil pan, make sure all oil has drained
from engine.
3.
Fill oil pan with amount of oil indicated as low level in
Table 7-1; allow sufficient time for oil to drain down into
the pan.
4.
Insert dipstick into dipstick tube until dipstick contacts
bottom of pan.
Measure distance dipstick protrudes
above tube, remove dipstick and cut off end the same
amount as measured protrusion (to bottom of cap).
5.
Insert dipstick all the way into tube.
Remove dipstick
and mark low oil level indicated.
Mark should be 0.010
inch [0.3 mm] deep.
Stamp (electric etch on spring steel)
letter "L" immediately above mark (Fig.
7-1).
Do not use
a chisel for marking, or stamp too deep.
This may cause
dipstick to break.
Cut excess length off dipstick leaving

6.
Add amount of oil to pan to bring to high level as
indicated in Table 7-1.
Allow time for all oil to drain into
pan.
Insert dipstick and withdraw; now mark oil level
indicated.
Stamp letter "H" immediately above mark.
7.
Mark opposite side of dipstick (if desired) for running
levels (Fig.

Running levels provide equivalent
readings to static levels with engine running at low idle
(550
25 RPM).
Add running level marks with oil supply,
low and high, as stated previously.
Note:
Running level readings require oil gauge tube with
increased internal length and an internal drilled hole to
provide for tube venting (if not originally equipped with
running level markings).
