7.3.15. CHANGING GEARBOX OIL
1. Place a pan under the drain plug.
2. Use a wrench and remove the drain plug.
3. Loosen the filler plug so air can enter the gearbox and the oil will drain freely
(see Figure 7.7).
4. Allow the oil to drain completely.
5. Replace the drain plug.
6. Add oil until the gearbox is half full (center of cross shaft) and replace filler
plug. A flexible funnel may be required. Gearbox should be level when
checking or refilling. Do not overfill.
