pressure gauge.
If the oil pressure is lower or higher than the
specification, the following causes may be
considered.
Oil pressure specification
140 – 180 kPa (1.4 – 1.8 kgf/cm
2 , 20 – 26 psi) at 3
000 r/min, Oil temp. at 60
°
C (140
°
F)
8) Stop the engine and remove the oil pressure gauge
and attachment.
9) Reinstall the main oil gallery plug (1) and tighten it to
the specified torque.
CAUTION
