temperature to go down before starting the work.
When removing the oil filler cap, turn it slowly to release the internal pressure, then remove it.
1. Remove the cap from oil filler (F), and release the internal
pressure.
2. Loosen 6 bolts, then remove cover (1). When doing this, the
cover may fly out under the force of spring (2), so push the
cover down when removing the bolts.

strainer (4).

oil. If strainer (4) is damaged, replace it with a new part.

tank, and assemble.
