CHAIN SYNCHRONIZATION
FIGURES 38 AND 39
When a new conveyor chain is installed, it is important to
synchronize both conveyor chains. The chains are syn-
chronized when the teeth on both chains are perfectly
centered with one another, as shown in figure 8.
Figure 38 Synchronized conveyor chains
Gears are synchronized at the assembly line.
Synchronization is not required in case of a chain
replacement. Simply install the new chains in the same
position as the old ones. If the chain tension is not
properly adjusted, synchronization may be lost and the
chain could skip a tooth over the drive sprocket. To solve
this problem, simply remove chain tension completely
and move the chain until it reaches the appropriate
position on the sprocket.
When replacing the belts or for any other reasons, it may
be necessary to remove the chain from the couplers
(item 1 figure 39) located underneath the gear boxes. To
easily re-synchronize the conveyor chains, mark with a
line the alignment of the coupler teeth (item 1 figure 39)

Figure 39
To synchronize, it is much easier to adjust only the
position of the right vertical shaft. First, slightly loosen
the chain tensioner (item 1, figure 33). With the coupler
chain removed, slowly rotate the right drum in order to
move the right chain forward in relation with the left chain.
It will be easier to achieve this by also removing tension
on the left chain. When the conveyor chain links are well
off-set, check to see if the teeth on the coupler are also
aligned. Rotate the drum until the chain and coupler
teeth are perfectly aligned for a perfect synchronisation.
NOTE : The synchronisation is satisfactory when the
conveyor chain links are interleaved (figure 38)
and the coupler teeth are well aligned (figure
39).
