This video describes the process of replacing a bearing on a Claas Rollant 44 baler roller. The same procedure applies to 46, 62, and 66 balers. The bearing dimensions are 30 x 62 x 35.7 mm, catalog number FD206, and only fit free rollers; the drive gears have thicker shafts. The required tools include a puller, WD fluid, a tire iron, a hammer, open-end wrenches, and a hex key.
