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

15. 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 washers (A) and spacer (F) on shaft.

16. Install washers (A) between spacer and the end of the shaft, so that washers are flush with the end of the 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.

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

    A - Cast Step

    B - Mounting Strap Edge

    C - Dimension, 1.5—4.5 mm (0.059—0.177 in)

    Add or subtract washers behind the bearing, if necessary, to locate cast step (A) correctly with mounting edge (B) in all three locations. Set mounting edge to specification (C).

    Cast Step	Distance	1.5—4.5 mm (0.059—0.177 in)

    E82582-UN-11APR17

    A - Flanged Cap Screw (3 used)

    B - Flanged Nut (3 used)

    C - Shims

    Install three flange mounting cap screws (A) and nuts (B). Only tighten cap screws enough to get a light between the cast flange and the 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 the roll is centered in the hole in the side sheet.

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

26. Do not tighten cap screws at this time.

27. 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 drive roll wiper pins to 3 mm (0.12 in) minimum height.

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

    Rollers to Side Sheet	Radial Clearance	1 mm (0.04 in)
