11.Check the conveyor configuration as follows:

•High-speed conveyors are equipped with large flange bearings at both ends of the shaft, as shown in Figure 4-5. For these conveyors, re- move the two screws that hold each bearing to the conveyor frame. With the screws removed, lift the end of the shaft at the front of the oven, and pull the entire assembly free of the conveyor frame.

•Standard conveyors are equipped with bronze bushings mounted on spacers at both ends of the shaft, as shown in Figure 4-5. For these convey- ors, remove the two screws that hold the bracket to the conveyor frame. With the screws removed, lift the end of the shaft at the front of the oven, and pull the entire assembly free of the conveyor frame. The brackets will be removed along with the drive shaft assembly.

12.Disassemble and lubricate the two sections of the drive shaft as described for the idler shaft, above.

13.Before reassembling the shafts into the conveyor frame, check that they are oriented properly.

14.Reassemble the drive shaft into the conveyor. Make sure that the bronze washer is in place between the two sections of the shaft. See Figure 4-6.

15.Replace the drive sprockets. Reassemble the belts and master links onto the conveyor.

16.Reinstall the end plugs and conveyor onto the oven.

17.Reattach the drive chains. Replace the chain cover.

18Check the tension of the conveyor belt as shown in Figure 2-11 (in Section 2, Installation). The belt should lift about 1" (25mm). If necessary, adjust the belt tension by turning the conveyor adjustment screws.
