All-Electric slicers have the drive pulley mounted directly on the motor shaft and the idle side pulley
uses sealed type bearings that typically do not need replaced. If bearing problems develop with
either the drive or idle side, contact the Grote Company Service Department for assistance.
Drive Side Bearing Removal - Hydraulic Slicers
1. Remove the four mounting bolts holding the motor to the flange mounting collar.
CAUTION: The motor will drop at this time if it is not supported. The motor
can be balanced in the hole through the frame.
2. Remove the entire bearing block assembly by removing the five mounting bolts on the
top and bottom of the assembly.
3. Place the bearing block assembly on a workbench and remove the coupling by
loosening the set screw through the slot in the flange mounting. Then remove the
square key in the shaft.
4. Remove the flange by removing the four cap screws holding it in place.
5. Remove the bearing locknut by first loosening the set screw and then removing the nut.
NOTE: A punch can be inserted through one of the holes in the pulley to "lock"
the pulley in place and allow the removal of the locknut.
6. Pull the shaft\pulley assembly out of the bearing block.
7. Remove the bearing housing cap.
8. Loosen the two set screws in the sides of the bearing block and offset the inner race
spacer.
9. Gently tap out the old bearings.
10. Remove the inner and outer race spacers.
Drive Side Bearing Replacement - Hydraulic Slicers
Carefully remove one of the seals on each of the new bearings.
1. Press the double row bearing into the front of the bearing block with the remaining seal
facing out.
2. Replace the outer race spacer in the rear of the bearing block and tighten the two set
screws in the sides of the bearing block.
CAUTION: The set screws must properly seat into the groove on the outer race
spacer or the spacer will be damaged.
3. Insert the inner race spacer.
4. Press the single row bearing into the rear of the bearing block with the remaining seal
facing out.
5. Replace the bearing housing cap.
6. Insert the pulley shaft assembly into the bearing block assembly.
