D. Split-belt Conveyor Shaft Cleaning

It is very important that the split-belt conveyor drive and idler shafts are removed from the conveyor frame for cleaning and lubrication.

SECTION 4

MAINTENANCE

4.Drop the idler shaft assembly clear of the frame through the front frame slot.

CAUTION

Use a turbine oil or light machine oil. DO NOT USE WD40 or similar product. These oils evaporate and cause the shafts to seize.

1.Perform the conveyor removal steps described in Monthly Maintenance, paragraph “A”. After the conveyor is removed, lay it on a flat surface.

2.Remove the two conveyor belts by disassembling the conveyor master links, as described in Monthly Mainte- nance, paragraph “H”. Then, remove the two conveyor belts by rolling them up.

3.Remove the conveyor adjustment bolts to allow the idler brackets to swing free.

Figure 4-39.

Figure 4-40.

5.Pull the front and rear shafts apart and apply oil to both the extended shaft and the interior of the hollow shaft. Using a rag, wipe oil off parts. Repeat until shafts are clean. Apply more oil to shafts then reassemble.
