careful not to damage the seal rubber.
5) Tighten more (approx. 1 turn for outer diameter
68 mm (2.68 in) oil filter, and 2/3 to 3/4 turn except
for outer diameter 68 mm (2.68 in) oil filter) after the

tighten excessively, or oil may leak.
6) After installing the oil filter, run the engine and
make sure that no oil is leaking around seal rubber.
NOTE:
The filter element and filter case are permanently
joined; therefore, interior cleaning is not necessary.
