12 ft Conveyor Grease Points Continued
12.11.3 Adjust the 12 ft Conveyor Chain
Tension
Check conveyor chain tension after the first 50 hours of
operation. Chains can stretch during this period. This is normal
wear in.
Recheck chain tension every 50 hours of operation.
Adjust as
required.
If excessive slack is observed, tighten the tension adjusters. Do
not over-tighten the chain. Over-tightening adds pretension into
the chain and reduces chain life.
IMPORTANT! The purpose of chain adjustment is to remove
slack from the chain. It is easy to over tighten the chain, so
great care is needed!
Measure conveyor chain slack from the topside, inside the
conveyor trough. Conveyor must be unfolded with side latches
secured.
Pull the chain up by hand at the middle and measure
distance
'X'.
Ideal chain slack is 3 inches (7.6 cm).

Chain Tensioner
1. Jam Nut
2. Adjuster Nut
3. Tension Spring
4. Spring Tensioner Nut
5. Tensioner Jam Nut
IMPORTANT! The tension spring (3) must be kept at the
same compressed length after adjustments are made.
Adjust both sides equally.
1.
Loosen jam nuts (1 and 5). Loosen off adjuster nut (2).
2.
Turn spring tensioner nut (4) clockwise so the spring
compresses enough to increase chain tension.
Make sure both sides of the conveyor are adjusted
equally.
It may be necessary to tap the bolt lightly to get
the spring to re-adjust the tension to the new
setting.
3.
Tighten adjuster nut (2).
4.
Tighten jam nuts (1 and 5).
