Row Unit Setup and Adjustment
The meter clutch and meter-input shaft must be aligned.
Misalignment will cause meter malfunction and excessive
meter-housing wear. Periodically check vertical and hori-
zontal alignment of meter clutch and meter-input shaft.
Refer to Figure 2-4.
1. Latch hopper onto hopper support.
2. Check that roll pin (1) in end of the meter-input shaft is
centered. When centered, equal amounts of the roll
pin will protrude from both sides of the shaft.
3. Rotate meter-input shaft so that roll pin is vertical.
4. Rotate the drive coupler (2) on meter clutch so that the
slots are vertical.
5. Release meter clutch to engage meter-input shaft.
6. If shafts are aligned vertically, the drive coupler will en-
gage with meter-input shaft freely and the roll pin will
extend equally on each side of the drive coupler. Dis-
engage the clutch and repeat steps, checking for hor-
izontal alignment.
