MAINTENANCE AND SERVICING
5.12.6 Header Draper Roller Maintenance
The draper rollers have non-greaseable bearings; however, the external seal should be checked every 200 hours
(more frequently in sandy conditions) to achieve maximum bearing life.
Inspecting Draper Roller Bearing
Using an infrared thermometer, check for bad draper roller bearings as follows:
1. Engage the header and run the drapers for
approximately three minutes.
2. Check the temperature of the draper roller bearings at
each of the roller arms (A), (B), and (C) on each deck.
Ensure the temperature does not exceed 80°F (44°C)
above the ambient temperature.
Replace roller bearings that exceed maximum
recommended temperature. Refer to
