   A - Flanged Cap Screw (3 used)

   B - Flanged Nut (3 used)

   C - Washers

   D - Large (Thick Washer)

   E - Cap Screw, M12 x 80 mm

   H - Washers, 45.2 x 57.5 x .9 mm (2 used) (Each Side of Bearing)

   Install three flange mounting cap screws (A) and nuts (B). Only tighten cap screws enough to get a light contact 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.

6. 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.

   Item	Measurement	Specification
   Rollers-to-Sidesheet	Clearance	1 mm (0.039 in.)

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

   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 on both sides.

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

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