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

10. Install one thin washer and spacer (F).

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

    Install washers (A) between spacer and end of shaft, so washers are flush with end of shaft, and add one washer (A). Add a thick, large ID washer (B). Install 13 x 57 x 6 mm (0.5 x 2.25 x 0.24 in.) washer (C).

12. Install M12 x 75 cap screw (D).

13. Tighten cap screw (D) to specification.

    A - Spacer

    B - Thin Washer

    C - Bearing

    D - Mounting Strap

    E - Cast Housing

    F - Cap Screw, M8 (3 used)

    Right-hand Side: Make sure that there are enough washers (B) between end of roll tube and bearing to locate bearing cast housing correctly. Remove three M8 cap screws (F) to be installed later.

    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.

18. 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.

    Rollers-to-Sidesheet	Clearance	1 mm (0.04 in.)

19. To avoid center cap screw from loosening or hex knock, keep washers (C) centered on shaft.

    Install 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).

20. Install M12 x 80 cap screw (E) and 13 x 70 x 12 mm (0.50 x 2.75 x 0.47 in.) end washer (G).

21. To prevent bearing failure, always tighten M12 cap screw (C) before tightening flange mounting M8 cap screws (A) and (B).

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