The lateral gearbox is lubricated with 0.7 L (24 oz) of extreme-pressure oil for mechanical transmissions
with viscosity grade SAE 80W90 and API grade GL4.
When draining and refilling, it is recommended to use either a mineral base oil with viscosity grade
SAE 80W and API grade GL4, or a synthetic base oil, type PAO (Poly-Alpha-Olefins) with a viscosity
grade equivalent to SAE 80W.
In certain countries SAE 80W GL4 oil may not be available. In this case a GL4 or GL5 grade
SAE 80W90 oil is an acceptable substitute for GL4 SAE 80W oil.
