GRAIN ELEVATOR
CHAIN TENSION -- Figure 52
The tension of the grain elevator chain can be ad-
justed at the top of the elevator , accessible through
the grain tank, after drive chain P has been slack-
ened.
Loosen bolts M and adjust with nuts N on both sides
of the elevator head.
ATTENTION:
To prevent bearing damage, ensure nuts N are
tightened evenly.
The tension of the grain elevator chain is correct
when it is just possible to move a link laterally across
the lower sprocket by hand.
