Tension
Proper chain tension is also a factor in chain and sprocket life� Measure from rear of main unit forward
to achieve proper chain tension (Figure 2)� Make sure chain is tensioned equally on both sides� This
adjustment is made on each side of the unit at the front idler bearings�
Chain Tension to be Measured
from Rear of Sill�
Proper Tension:
Main Unit Conveyor
36” to 40”
(9144mm - 1016mm)
MULTAPPLIER/MULTIBIN
Conveyor
30” to 34”
(762mm - 864mm)
Figure 2 - Chain Tension
Conveyor chains that are too tight will tend to stretch, causing excess sprocket wear and eventually
breakage� Excess slack presents the possibility of chain catching on sub-frame parts� Bent or distorted
chain bars will cause damage to unit as well as fertilizer leakage with #3 conveyors� Straighten or replace
bent or distorted chain bars immediately�
Conveyor Belt Maintenance
Standard belt for the #4 chain is moderate oil resistant that is impervious to moisture, weathering, or
normal action which can be used with chemical impregnated fertilizer or oil based additives�
• Inspect belt fastener occasionally for wear or “raveling” of belt grip area�
• Make sure belt connecting pin is positioned correctly as shown in Figure 3�
Pin must not rotate� If pin ends are
not bent down and tight against
lacing, the ends may cut into the
chain shield sealers or belt wipers�
BOTH PIN ENDS MUST
BE BENT DOWN &
TIGHT AGAINST ENDS
OF LACING
