6. Using a pry bar gently press down (applying 10 to 15 pounds of pressure) on the Idler assembly taking
up all slack in the chain. Refer to photo

5.2.4 Bearings
Lubricating
The barrel and turret bearings must be periodically lubricated with water-resistant grease, such as Deoplex
Multi-Purpose #2EP, to maintain their service life. Each of the eight (8) barrel bearings (four per side) is
equipped with a zerk-fitting for this purpose. Refer to photo 5-9 and 5-10 for zerk-fitting locations.
When lubricating, add only a small amount of grease at any one time, usually only one or two pumps on a
grease gun. Adding too much will result in damage to the seal, which will allow water and process chemicals to
enter the bearing. If this occurs, the bearing will have to be replaced within a short period of time.
Barrel Bearing - Replacement
1. Empty ALL barrels, position into the cradles and latch cradle lids.
2. Turn OFF the power at the safety disconnect and lock the handle in this position.
3. Release the motor brake by pulling outward on the brake release knob shown in photo 5-4 Motor Brake.
4. Position the turret so that the barrel bearing to be replaced is conveniently located and set the motor
brake.
5. Remove the two (2) retaining bolts holding the idler arm assembly in place and remove the Idler arm
from the turret.
6. Loosen the setscrews holding the sprocket to the shaft, and slide the sprocket off the barrel shaft, using
a bearing puller if necessary.
7. Loosen the two (2) setscrews holding the bearing onto the shaft.
8. Remove the two (2) retaining bolts holding the bearing to the turret and slide the bearing off the shaft.
9. Install the new bearing using the method shown in photo 5-11 Install Barrel Bearing. Measure the
distance from the center shaft to the cradle shaft center point. The distance should equal that of the
existing bearings or exactly 8 inches. Torque bearing retaining bolts to 80 ft-lbs.
10. Proceed to line #9 in Drive Component Removal in the previous section for installation instructions.
11. Lubricate the new bearing according to the instructions given in the section Lubricating.
Turret Bearing - Replacement
