2. The drain plug is magnetic. Check the plug for metal.

3. Clean the drain plug and install the drain plug.

4. Remove oil level/fill plug (2).

5. Add oil until the oil is level with the threads for the filler plug. Refer to Operation and Maintenance Manual, “Lubricant Viscosities” and Operation and Maintenance Manual, “Capacities (Refill)” for oil.

1. Clean the area around the breathers. Remove the breather from the front axle.

2. Wash the breather in clean nonflammable solvent. Wipe the breather dry and check the breather for damage.

3. Install the clean breather back into the axle. Replace the breather if the breather is damaged.

Note: Make sure that the slot in the breather is parallel to the axle housing.

If new belts are installed, check belt adjustment after 30 minutes of operation. For multiple belt drive applications, always replace the belts in matched sets. Replacing only one belt of a matched set will cause the new belt to carry more load because the older belts are stretched. The additional load on the new belt could cause the new belt to break.

2. Inspect the condition of the serpentine belt. If the belt is worn or frayed, replace the belt.
