STEEL HOPPER SPREADERS – GAS, ELECTRIC & HYDRAULIC: CONVEYOR CHAIN: FLEET FLEX SYSTEM
REPLACING THE CONVEYOR CHAIN
NOTE: For Gas Models: Remove the spark
plug wire and isolate. For Electric Models:
Disconnect electrical connections. For
Hydraulic Models: Disconnect hydraulic hoses.
Removing the Conveyor Chain
1. Locate the master link in the conveyor chain.
Rotate the chain until the master link is at the
drive sprockets.
2. Loosen the fasteners on each of the idler shaft
bearings located at the front of the spreader on
both sides of the sill.
3. Loosen the take-up bolts enough to allow the
idler shaft to slide back evenly. This will allow
the conveyor chain to slacken.
4. Remove the cotter pins from the master link
on each side. Pull each link pin out. There
may still be some tension on the pin due to the
weight of the chain.
5. Tie a rope to the bottom end of the existing
conveyor chain. Holding the top end of the
chain, pull the chain out. It may take two
people to remove the chain. The rope will feed
up through, which will make it much easier for
installing the replacement chain.
Installing the Conveyor Chain
1. Inspect all bearings, idler shaft, etc., before
installing the conveyor chain.
2. Starting with the closed link on the end of the
chain, tie the end of the rope on the top side of
the sill to the chain, making sure that the offset
in the crossbar is facing down.
3. Pull on the other end of the rope while guiding
the chain up over the drive sprockets. It may
take two people to install the chain. Make sure
that the chain is positioned correctly into the
idler sprockets at the front of the spreader.
4. Once you have pulled the chain into position,
install the link pins with cotter pins, separating
and bending both legs of the cotter pin.
5. Tighten the take-up bolts evenly from side to
side until the conveyor chain is visible through
the chain tension port. You should be able to
lift up the chain 1"
–
3" at approximately
20"
–
24" from the rear of the spreader.
6. Once the correct chain tension has been
achieved, tighten the four bearing mounting
bolts.
7. Run the spreader to verify that the chain
tension is correct and running true. Make
adjustments as needed.
NOTE: Having the conveyor chain too tight will
put additional load on the entire drive system
and will increase the amperage draw on
electric units.
NOTE: On electric units, make sure to calibrate
the empty hopper function of the control.
