3.10.1 Change the metering wheels

Procedure
1.
Lower the plenum (1) and turn the tractor off.
2. Turn the welded hex nuts (2) to close the
hopper gates (3) for the front and rear tanks.
3.
Release the clean out tray latches (4).
4. Use the clean out tray handle (5) to open the
clean out tray and remove any product.
5. Lower the meters by the two large over
center latches (6) on each side of the meter.
6. Pull the hairpins (1) to remove the motors (2).
NOTE: The key may fall out when the motors
are removed.
7.
Remove the four 1/4 inch bolts (3) on the
flange bearings (4).
8. Pull the shaft assembly straight out of the
meter.
9. Remove the 5/8 inch lock collars (5) on one
side.
10. Move the spacers (6) and metering wheels
(7) off of the shaft.
11. Assemble the meter in the opposite order with the necessary metering wheels.

3.10.2 Meter latches

The meter latches can be adjusted to let the
meter close tight against the hopper shut off
assembly where product does not leak out.
With the meter correctly adjusted, there should be
no gap seen between the meter and the shut off
assembly.
To adjust the meter to hopper shut off:
1. Loosen the jam nuts (1) and the two 3/8 inch
carriage bolts (2) on the over center latches.
2. Extend or retract the carriage bolts until there is
correct preload on the clamp. If the preload is
too small the meter will not seal correctly. If too
tight the clamp will not close.
3. If necessary, loosen the two 3/8 inch bolts (3) on
the rear hinge of the meter. This will let the meter
lift or lower at the hinge.
