Carefully and thoroughly inspect all drive unit parts before assembly. Thorough inspection of the drive parts for wear or stress with subsequent replacement of worn parts eliminates costly drive component repair after assembly.
Important: Bearings and cups are matched sets. Replace both bearing and cup when
either part requires replacement.
• Inspect the bearings for smooth rotation. • Inspect the bearing rollers for wear. • Inspect the bearing cups for wear, cracks, brinelling, and scoring.
