Eight numbers (1 to 8) are printed on the surlace ol
the filter.
The lollowing explains the procedure for tightening
filters using these numbers.
1) Make a mark on the engine oil cooler (818c5
engine) or cylinder block (8188'1, 818C1 engines)
under the number that shows at the bottom of
the filter when the rubber seal is seated.
2) Tighten the filter by turning it clockwise seven
numbers Irom the marked point. For example, if a
mark is made under the number 2 when the rub
ber seal is seated, the filter should be tightened
until the number 1 comes up to the marked point

5. After installation, fill the engine with oil up to the
specilied level, run the engine for more than 3 min-
utes, then check for oil leakage and oil level.
CAUTION: Installation using other than the above
procedure could result in serious engine damage
duo to oil leakage.

Overhaul
NOTE:
a Use new O-rings when reassembling.
a Apply oil to O-rings belore installation.
. Use liquid gasket, Pan No. 08718 - 0001 or 08718 - 0003.
a After reassembly, check that the rotors move without binding.
