10.3.6 Draining the Gyrodine gearbox
Gyrodine gearbox:
- Remove filler/level plug (1) and its seal.
-
Place a container with a capacity of at
least 3 L (101 oz) under plug.
- Remove drain plug (2) and its washer.
- Allow oil to drain completely.
- Wait for dripping to stop.
-
Clean and reinstall drain plug (2) and its
washer. (Replace if necessary).
- Torque to 200 Nm (147.5 ft lbs).
- Pour the correct oil quantity and quality through
the opening of the filler plug (1).
- Check oil level in lower gearbox:
• The "MAX" level corresponds to the mark on the
dipstick plug (1).
• The "MIN" level corresponds to the end of the
dipstick plug (1).
-
Clean and reinstall filler plug (1) and its
washer (Replace if necessary).
Before draining oil, operate the machine for a
few minutes so that the oil warms up.
The Gyrodine gearbox is lubricated with
2.7 L (91 oz)
of extreme-pressure gear oil with
SAE 80W90 viscosity grade API and 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.
