SICKLE AND SICKLE DRIVE (continued)
Sickle Head Needle Bearing Installation

same diameter as the bearing, push the bearing
into the sickle head until the top of the bearing is
flush with the step (B) in sickle head.

sickle head before installing bearing. Assemble the
bearing with the stamped end (the end with
identification markings) against the tool.
