Preventive Maintenance and Adjustment

Figure 49

Periodic Cleaning

Dorner recommends complete disassembly of the conveyor
periodically for thorough cleaning.

For conveyor disassembly and reassembly instructions:

• Refer to “Conveyor Belt Replacement” on page 19.

• Refer to “Sprocket and Puck Removal” on page 22.

• Refer to “Reassembling Tail Assemblies” on page 25.

Lubrication

Conveyor Bearings

Conveyor bearing lubrication is required. Dorner
recommends using an H-1 food grade grease.

Add grease to the bearing using the zerk fitting

(Figure 50, item 1)

on the exterior of the bearing shaft

assembly.

Figure 50

Replace the bearings if they become worn.

Wearstrips and Belt Returns

Replace the wearstrips and belt returns if they become worn.

For wearstrip and belt return installation instructions:

• Refer to “Wear Strip Installation” on page 14.

• Refer to “Belt Return Installation” on page 16.

Maintaining the Conveyor Belt

Troubleshooting

Inspect conveyor belt for:

• Surface cuts or wear

• Skipping

Damage to belt links or rods, surface cuts and / or

wear indicate:

• Sharp or heavy parts impacting belt

• Jammed parts

• Accumulated dirt

• Foreign material inside the conveyor

• Improperly positioned accessories

Skipping indicates:

• Excessive load on belt

• Worn sprockets or impacted dirt on drive pulley

Damage to belt links or rods indicate:

• Excessive load on belt

• Dirt impacted on sprockets

• Excessive or improper side loading

• Improperly positioned accessories

CAUTION

DO NOT submerge or soak bearing
assemblies. This will reduce the life of the
bearing.

NOTE

Although bearings are sealed, re-greasing is
recommended to increase bearing life. An

H-1 food grade grease is recommended. The
frequency of bearing re-greasing is
dependent upon the application in which the
conveyor is being used. Frequency of re-
greasing will increase with the frequency of
conveyor washing.

NOTE

troubleshooting solutions.
