Checking Pickup Tooth End Play

CAUTION: To avoid injury or death caused by unexpected lowering of the gate, engage gate lock before working on, around, or under gate in raised position.

Excessive tooth end play in the feed opening area will reduce bale starting and feeding performance. Worn cams, spider bores, cam arm shafts, and cam bearings contribute to excessive tooth end play.

To check for end play:

1. Fully raise and lock gate.

2. Raise the pickup to transport position.

CAUTION: Never use any type of tool or wrench on shaft while tractor engine is running. Always remove tool from shaft as soon as you are finished using it.

3. Put a wrench on the gear case output shaft. Turn wrench clockwise until a row of pickup teeth are straight up.

4. Rotate the tooth bar forward, by hand, until the rotation has stopped. Mark the position of the outside tooth tip (A) on the end stripper panel.

5. Rotate the tooth bar rearward, by hand, until the rotation has stopped. Mark the position of the outside tooth tip (B) on the end stripper panel. Measure and record the distance between marks.

6. Mark the row and repeat steps 3 through 5 on the remaining rows of teeth.

7. If the average distance (C) between marks exceeds specifications, check wear in cam(s), spider bores, cam arm shafts, and cam bearings, and replace as needed.
