MAINTENANCE
• Lubrication
The drive chain is pre-lubricated from the manufacturer by a hot dipping
process that ensures total lubrication of all components. However, continued
proper lubrication will greatly extend the useful life of every drive chain.
drive Chain lubrication serves several purposes including:
• Protecting against wear of the pin-bushing joint
• Lubricating chain-sprocket contact surfaces
• Preventing rust or corrosion
for normal operating environments, lubricate every 2080 hours of operation
or every 6 months, whichever comes first. Lubricate with a good grade of
petroleum or synthetic oil (i.e., Shell Rotella or mobil 1). for best results,
always use a brush to generously lubricate the chain. The proper viscos-
ity of lubricant greatly affects its ability to flow into the internal areas of the
chain. Refer to the table below for the proper viscosity of lubricant for your
application.

The drive chain's lubrication requirement is greatly affected by the operating
conditions. for harsh conditions such as damp environments, dusty environ-
ments, excessive speeds, or elevated temperatures, it is best to lubricate
more frequently. It may be best, under these conditions, to develop a custom
lubrication schedule for your specific application. A custom lubrication sched-
ule may be developed by inspecting the drive chain on regular time intervals
for sufficient lubrication. Once the time interval is determined at which the
chain is not sufficiently lubricated, lubricate it and schedule the future lubrica-
tion intervals accordingly.

• Belt Replacement
mOdEL "ACC"
1. Check length of section in which belt is to be replaced.
2. determine if a "Long" or "Short" belt is needed. See (figure 8A)
3. See Parts List for correct replacement number. (Pages 12-13). See notes
on page 9.
TO REPLACE BELT
1. Using knurled nuts, lower belt away from tread rollers in section where belt
is being replaced.
2. Remove five tread rollers from each end of section.
3. Remove all pressure rollers.
4. Replace belt and all rollers.
5. Adjust accumulation pressure per instructions. (Pg. 6)
mOdEL "LRC" , "LRS" , & "LRSS"
1. Check Overall frame Width (OAW) (figure 8B).
2. determine degree of curve or spur.
3. See respective Parts List for correct replacement number. (Pages 14-23).
See notes on page 9.
TO REPLACE BELT
1. Not how existing belt is installed.
2. Remove all tread rollers.
3. Replace belt and all rollers.
4. Adjust belt tension per instructions on page 9.
during installation, do not use tools such as screwdrivers, wrenches, etc., or
damage to the V-belts could occur.
NOTE: Special length V-belts are used on the "ACC" & "LRSS" convey-
ors. It is recommended that replacements be obtained from HYTROL.
The Models "LRC" & "LRS" use standard "B" section industrial grade
V-belts (Non-Glass Core). These belts may either be purchased from
HYTROL or local suppliers.
