Shaft Alignment

Refer to Figure 75 and Figure 76

Improper shaft alignment can cause pins to shear. To

function properly, transmission shafts must be aligned

and level. If the planter is consistently shearing pins,

follow these steps to check and adjust the shafts.

Check that transmission input shaft and transmission

shaft are aligned:

1. Remove cotter pin from coupler sleeve .

2. Pull coupler sleeve back and observe the shafts.

If shafts are not aligned, adjust contact-drive tower:

3. Loosen mounting bolts on both sides of tower.

4. Adjust tower position until shafts are aligned.

5. Retighten tower mounting bolts.

6. Slide coupler sleeve over transmission input shaft

and reinsert cotter pin.
