Adjustments
Conveyor Flight Chain
Adjustment
For cold weather, keep conveyor ight
chain properly oiled with cleaning solvent or release
agent. This will prevent conveyors from sticking.
NOTE: The conveyor should run smooth when conveyor
chain is properly adjusted. These chains should
be adjusted every 100 hours to maintain smooth
operations. If irregular movement of the conveyor
occurs, this is generally a sign that an adjustment
is needed.
Use the following procedure to make adjustment:
NOTE: Front of paver must be run up on ramps to
perform this adjustment.
1. Loosen the locknut (Figure 7-7,2) and bolt holding
the Adjustment Roller Assembly.
2. Turn adjustment bolts (Figure 7-5,1) alternately
on both sides of the conveyor. Turn one bolt one
half turn, then the other bolt one half turn. Continue
alternating tightening until chains are tight. (The
pressure on the chain will be noticeable as the bolts
are tightened.)
NOTE: Drag chains should be 1/2” away from rear frame
channel.
3. After the conveyor chain tension is set, tighten
locknut (Figure 7-7,2) and bolt holding assembly.
4. If the adjustment bolts (Figure 7-5,1) have been
run out, it will be necessary to remove a link in the
conveyor chains and add a half link. This repair
should bring the adjustment bolts back to full travel.
5. Repeat steps 1 through 4 for the opposite side.
6. Grease front and rear conveyor tubes at grease
blocks on each side of conveyor. This will grease
between the two bearings on each side of tube.
