  14. Hold upper roll shaft to left-hand side and push upper drive roll sprocket (E) and washers inward.

  15. IMPORTANT: To avoid center bolt loosening or hex knock, keep washers (A and B) centered on shaft. Ensure that washers do not rotate by hand. Joint must be clamped to eliminate hex knock.

    Install two washers (A) and spacer (F) on shaft.

  16. Install washers (A) between spacer and end of shaft, so washers are flush with end of shaft, and add one washer (A). Add a 6 mm (0.25 in.) washer (B). Install washer (C).

  17. Install and tighten cap screw (D) to specification.

    G - Washer, 13 x 70 x 12 mm

    H - Washer, 45.2 x 57.2 x .9 mm

    Install three flange mounting cap screws (A) and nuts (B). Only tighten cap screws enough to get a light between cast flange and mounting strap. Some rotation (a light tap) of the cast flange around the outer race can be required to align flange correctly at all three locations. Do not tighten cap screws at this time.


  24. Check to see if roll is centered in hole in sidesheet.

  25. If necessary, loosen cap screws (A) and flange nuts (B) to insert shims (F) between bearing mounting flange and cast bearing flange to center roll in holes in sidesheet.

  26. Do not tighten cap screws at this time.

  27. NOTE: Rolls must rotate freely. Check roll clearance through hole in sidesheet.

    If roll is equipped with wiper pins, it is permissible to grind drive roll wiper pins to 3 mm (0.12 in.) minimum height.

    Spin upper drive roll to verify clearance with sidesheet hole according to specifications. Add or remove shims (F) or move right-hand bearing plate, or grind drive roll wiper pins, if equipped.

  28. IMPORTANT: To avoid center cap screw from loosening or hex knock, keep washers (C and D) centered on shaft.

    Install one washer (H) and washers (C) between bearing and end of hex shaft, so washers are flush with end of shaft, and add one more washer. Add large thick ID washer (D). Washer (H) must be next to bearing.

  29. Install cap screw (E) and end washer (G).

  30. IMPORTANT: To prevent bearing failure, always tighten cap screw (C) before tightening flange mounting cap screws (A and B).

    NOTE: Ensure that washers do not rotate by hand. Joint must be clamped to eliminate hex knock.
