6. Washer (C) must be next to the bearing.

   Install four washers (B) and washer (C).

7. Install bearing (D) and hold it tight against the washers.

8. Check the distance (G) between the outer edge of the step in the bearing housing (E) and the edge of the mounting bracket (F) at all three locations. Verify that the dimension is within specification.

   Distance (G)	Distance	1.5—4.5 mm (0.059—0.177 in)

9. If the distance (G) is not within specification:

   1. Remove the bearing (D) and washer (C).

   2. Add or remove washers (B) as necessary.

    A - Cap Screw, M8 (2 used)

    B - Cap Screw, M10

    C - Shim (as required)

    Install previously removed cap screws (A and B). Tighten the cap screws only enough to get a light load between the bearing housing flanges and the mounting bracket. If necessary, lightly tap on the bearing housing to rotate the housing slightly and align the flanges with the bracket.

11. Check to see if the drive roll is centered in the side sheet.

12. If the roll is not centered:

    1. Loosen cap screws (A and B).

    2. Insert shims (C) between the bearing mounting bracket and the bearing housing flanges as necessary.

    3. Snug up the cap screws but do not fully tighten at this time.

13. Rolls must rotate freely. Check roll clearance through the hole in the side sheet.

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

    To verify that the clearance with the side sheet hole is according to the specifications, spin the upper drive roll. Add or remove shims (C) or move the right-hand bearing plate, or grind the wiper pins (if equipped).

    Roller-to-Side Sheet	Radial Clearance	1 mm (0.04 in)

    A - Washer, 45.2 x 57.2 x 0.9 mm

    B - Washers (as required)

    C - Thick Washer, Large ID

    D - Washer, 13 x 70 x 12 mm

    E - Cap Screw, M12 x 80

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

    Washer (A) must be next to the bearing.

    Install washer (A) and washers (B) between the bearing and the end of the hex shaft. Add washers (B) until flush with the end of the shaft, then add one more washer. A washer must be next to the bearing on both sides.

15. Install the large ID thick washer (C).

16. Install end washer (D) and cap screw (E).

    A - Cap Screw, M8 (2 used)

    B - Cap screw, M10

    C - Cap Screw, M12 x 80 mm

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

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

    Tighten cap screw (C) to specification.

    M12 Cap Screw	Torque	140 N·m (103 lb·ft)

18. Tighten the middle flange mounting cap screw (B) first, then tighten cap screws (A). Tighten all cap screws to specification.

    Cap Screw (B)	Torque	80 N·m (59 lb·ft)
    Cap Screw (A)	Torque	40 N·m (30 lb·ft)

19. Check the distance between the outer edge of the step in the bearing housing and the edge of the mounting bracket in all three locations as previously described. If the distance is not within specification at all locations, repeat the previous steps to adjust and recheck.
