B. BEARING HOUSING LUBRICATION
1. Unplug grinder from power source and perform lockout/tagout procedures.
2. Remove bolted on tray.
3. Check and relubricate with good grade of lithium bearing grease semi-annually.
4. Reinstall tray and bolt on tightly.
C. ROLLER CHAIN AND DRIVE SPROCKET LUBRICATION
Chains should be protected against dirt and moisture. Chain life will vary appreciably depending upon its lubrica
-
tion. The better the lubrication, the longer the chain life.
Lubrication effectiveness will vary with the amount of lubrication and frequency of application. Ideally, a lubricant
film should always be present between the working parts. Manually lubricate the chain after the 1st six weeks then ev
-
ery 6 months thereafter.
Lubricating just the outside of the chain does little good. Apply lubrication on the inside of the chain span so that
it will work through the moving parts and joints by centrifugal force as the chain rotates and reach the area where one
surface “scrubs” another.
Recommended types of chain lubricant are those with Molybdenum Disulphide or Graphite added. Also bonded
lubricants such as Dow Corning’s Molykote 321R or equivalent are excellent for open chains. The lubricant should be
of a viscosity whereby it will “flow” somewhat and penetrate the internal working surfaces. Thick stiff greases are of lit
-
tle value because they cannot work into moving parts of the chain.
Symptoms of Inadequate Lubrication:
1. Excessive noise
2. Chain becomes stiff
3. Chain runs hot
4. Broken pins, bushings or rollers
5. Excessive chain elongation — caused by wear on the pin outside diameter and pushing inside diameter
Once a chain is elongated or worn past acceptable limits, jumping of sprocket teeth and/or improper
chain/sprocket mesh will occur.
LUBRICATING CHAIN AND SPROCKETS
1. Unplug grinder from power source and perform lockout/tagout procedures.
2. Remove bolted on tray.
3. Spray or brush lubricant on inside of chain, slowly and carefully turning large sprocket by hand.
4. Reinstall tray and bolt on tightly.
D. MAIN DRIVE CHAIN TENSION LUBRICATING CHAIN AND SPROCKETS
1. Unplug grinder from power source and perform lockout/tagout procedure.
2. Remove feed tray.
3. Loosen motor mounting bolts.
4. Remove shims from under the motor. Important to remove same shims from back of motor as from the front for
proper sprocket alignment.
5. Total chain flex should be
1
8
"to
3
8
" for proper chain tension. Do not over tension as this can cause excessive
wear or premature failure of motor bearings and journal box bearings.
6. Retighten all motor mounting bolts.
7. Reinstall feed tray.
