       Important: Bearings and cups are matched sets. Replace both bearing and cup when either part requires replacement.

    • Before assembly, carefully and thoroughly inspect all drive unit parts for wear or stress. Replacement of worn parts eliminates costly drive component repair after assembly.
    • Oil the bearings. Inspect the bearings for smooth rotation.
    • Inspect the bearing rollers for wear.
    • Inspect the bearing cups for wear, cracks, brinelling, and scoring.
