Lubrication and Maintenance
7.
Check indentations on carrier plate for wear before installing
finger holder on carrier plate. Excessive wear of carrier plate
at indentations will cause over planting especially with small
sizes of seed. Inspect carrier plate annually. Life expectancy
should be 250-300 acres (100-125 hectares) per row of
operation under average conditions.
8. Install wave washer and adjusting nut with finger holder
flush against carrier. Tighten adjusting nut to fully compress
wave washer. Back off nut ½ to 2 flats to obtain rolling
torque of 22 to 25 inch pounds (2.5 N-m to 2.8 N-m).
9. Turn finger holder by hand to make sure it is firmly against
carrier plate, but can be rotated with moderate force.
10. Install cover nut and cotter pin. Reinstall baffle.
Remove four cap screws around edge of housing cover and nut from belt idler mounting bolt. Paddles must be correctly
oriented as shown above If belt is replaced. A diagram molded into drive sprocket shows correct orientation.

NOTE: Check adjusting nut tightness on each unit after first day of use and periodically thereafter.
Reinstall housing cover. DO NOT TIGHTEN hardware. Wedge a screwdriver between sprocket hub and housing cover
as shown above. Pry cover down until centered on belt housing and tighten hardware. Rotate meter drive shaft and
check idler alignment. Seed belt should “run” centered on idler or with only slight contact with belt housing or cover.
