Inspect shaft (4) for chips, breaks, cracks, burrs, or uneven wear. Replace if chipped, broken, cracked, burred, or worn unevenly. 17. Measure outside diameter of shaft (4) at spline (10) where front bearing (3) fits. Refer to table 10-2. Wear Limits, for measurements. Replace if not within wear limits. 18. Measure outside diameter of shaft (4) at spline (9) where pinion (5) fits. Refer to table 10-2, Wear Limits, for measurements. Replace if not within wear limits. 19. Inspect bearing (3) for chips or distortion. Replace if chipped or distorted. 20. Measure inside diameter of inner race on front bearing (3). Refer to table 10-2, Wear Limits, for measurements. Replace bearing (3) if not within wear limits. 21. Measure outside diameter of bearing seat (1). Refer to table 10-2, Wear Limits, for measurements. Replace bearing (3) and bearing seat (1) if not within wear limits. 22. Measure outside diameter of bearing seat (7). Refer to table 10-2, Wear Limits, for measurements. Replace rear bearing (6) and bearing seat (7) if not within wear limits. 23. Measure diameter of bearing seats (1) and (7) openings in carrier housing (2). Refer to table 10-2, Wear Limits, for measurements. Replace housing and cap assembly (2) if not within wear limits. Table 10-2. Wear Limits.
