Inspect and Service the Meter

CAUTION:

A80090-UN-23SEP14

A - Inner and Outer Double Eliminators

B - Hub Seal

Annually inspect the ExactEmerge™ seed meter for wear and chemical or seed treatment buildup.

1. IMPORTANT: Degraded meter performance, like multiple seed placement, is an indicator of possible inner or outer double eliminator wear.

   Check the inner and outer double eliminators (A) for wear. If the length of the outer double eliminator measures less than 9.5 mm from the base Tine or Brush to the tip and the meter performance is degraded, replace it. If the diameters of inner adjustable double eliminator Tines are worn to less than 1/2 the original diameter and the meter performance is degraded, replace it.

2. Replace the hub seal (B) if it is cracked or weathered.

3. NOTE: Before replacing the seed bowl disk, properly set the meters and the vacuum.

   If the metering performance is satisfactory, it is not necessary to replace the seed bowl disk.

   A - Wear Example

   B - Worn Edge (Seed Cell Side View)

   C - Wear Example

   D - Wear Example

   Check the seed bowl disk for wear in the following areas and replace as needed.

   A small amount of wear (A) around the perimeter of the bowl disk is acceptable. If worn, check for seed loss through the gap between the bowl disk and the housing.

   Seed loss is eliminated with hub adjustments. (See Adjust The Meter Hub Height in the ExactEmerge™ Meter Operation section.)

   Inspect the individual seed cells. Seed abrasion wears sharp edges on the seed cells (B) and increases the cell size. (Increased cell size causes overpopulation when planting small seed or causes under-population when planting large seed). Replace the seed bowl disk if the cell size is increased and field checks determine a reduction in accuracy.

   Small grooves or scratches (C) are acceptable on the vacuum side of the seed bowl disk.

   Wear around the perimeter (D) of the bowl disk is acceptable up to an approximate depth of 1.0 mm (3/64 in).

4. NOTE: If the vacuum seals are replaced, apply Graphite Spray TY25797 on the vacuum side of the used seed bowl disks. See the Lubrication section. New seed bowl disks are lubricated from the factory.

   A - Components

   Annual cleaning of the seed meters and the seed bowl disk is recommended. To remove any seed treatment buildup, use a mild detergent and a soft brush behind the components (A) in the seed meter housing.
