4. Two Wheel Drive Heavy Duty Axle Spindle Bearings/Pivot Pins - When operating in mud and water, grease fittings (both sides) every 10 hours. Normal conditions grease fittings (both sides) every 50 hours.

   Feeder House Reverser Drive Gearcase - Turn sheave so fittings are in the 12 and 2 o’clock positions.

   When operating in severe conditions or high yielding corn, grease fitting at 12 o’clock position, 5 - 8 pumps every 10 hours. Excess grease will purge from under spring.

   Grease fitting at 2 o’clock position, 2 - 3 pumps every 10 hours. Over greasing this fitting can allow grease to purge on belt and cause belt failure.

   When operating in normal conditions, grease 12 o’clock fitting (10 - 15 times) and 2 o’clock fitting (5 - 8 times) every 50 hours. After greasing, cycle variable sheaves through speed range a couple of times to ensure grease spreads evenly over cam surfaces.
