SECTION 4 - MAINTENANCE

2.

Remove the master links from each conveyor belt.

 

Then, roll the belts up along the length of the conveyor

 

to remove them from the frame.

3.

Remove the two conveyor adjustment screws from the

 

idler end of the conveyor frame, as shown in Figure 4-

 

4.

4.

Remove the idler shaft assembly from the conveyor.

5.

Pull apart the two sections of the idler shaft.

6.

Clean the shafts thoroughly using a rag. Then, lubri-

 

cate both the extended shaft and the interior of the

 

hollow shaft using a light food-grade lubricant. DO

 

NOT lubricate the shafts using WD40 or a similar

 

product. This can cause the shafts to wear rapidly.

7.

Before reassembling the shafts into the conveyor

 

frame, check that they are oriented properly.

9. Replace the conveyor adjustment screws as shown in

 

Figure 4-4. To allow the conveyor belt to be reinstalled

 

later, do not tighten the screws at this time.

10.

Loosen the set screw on both of the conveyor drive

 

sprockets. Then, remove the sprockets from the shaft.

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.

19. Replace all components onto the oven.
