5.12.6 Draper Roller Maintenance
The draper rollers have non-greaseable bearings. The external seal should be checked every 200 hours (more
frequently in sandy conditions) to obtain the maximum bearing life.
Inspecting Side Draper Roller Bearing
If a bad bearing is suspected in one of the draper rollers, a quick way to check is by using an infrared thermometer.
1. Engage header and run for approximately
three min utes.
2. Check the temperature of each of the roller
arms (A), (B), and (C) on each deck. T h e temperature
should not exceed 80°F (44°C) above ambient
temperature.
