5.2.3 Retiming clamp wheels
The clamp wheels are designed to drop seed pieces into the planting shoe in an alternating sequence. To
maintain proper seed spacing, the dimensions between the clamp arms on the facing clamping wheel
must be equal. Should wear, mechanical damage or repairs change this dimension, retime the clamp
wheels by following this procedure:
1. Clear the area of bystanders, especially small children.
2. Raise the machine and place safety stands under the front frame.
3. Measure the distance between the clamp arms to see if they are centered between the two arms on
the opposite wheel.
4. If not equal:
a. Loosen the bearing mounting bolts on the clamp
drive sprocket shaft.
b. Slide the drive shaft back until the driving sprocket
clears the wheel.
c. Rotate the clamp wheel until the measurement
between the arms are equal. Timing notches on
wheel can be used as a guide.
d. Slide the drive shaft back into place and secure
bearings in place.
e. Check the arms to ensure they are properly spaced.
f. Repeat procedure if not properly spaced.
5.2.4 ROW UNIT SHEAR BOLTS
The drive of each row unit is protected by shear
bolts on the driving sprocket should the picker
wheel jam. To replace shear bolts, follow this
procedure:
1. Clear the area of bystanders, especially small
children.
2. Place all controls in neutral, stop engine, set
the park brake, and remove ignition key.
3. Carefully remove remaining shear bolt using
a hammer and punch if necessary. Do not
enlarge holes.
4. Install new shear bolts (2 required and
tighten).
