IMPORTANT! The main requirement of chain adjustment is
to remove slack from the chain (take up the clearances in
each link). It is easy to over tighten the chain, so great care
is needed!
Measure conveyor chain slack from the topside, inside the
conveyor trough. Pull the chain up at the middle and measure
dimension X. Adjust accordingly.
X
Ideal Conveyor Chain Slack (X)
16 ft (4.8 m) Conveyor X = 4" (10 cm)
24 ft (7.3 m) Conveyor X = 6" (15 cm)

Lower the conveyor down so the chain tensioner can be
adjusted from the ground.
1. Loosen sled tensioner bolts (5) on both sides of the
conveyor.
2. Back off the jam nuts (4) a slight amount.
3. Take the slack out of the chain by tightening (turning
clockwise) adjuster nuts (3) equally. Refer to table above.
4. Tighten the jam nuts (4).
5. Tighten the sled bolts (5).
8.6 Drive Belt, Adjust / Replace
8.6.1 Adjust Drive Belt Tension
1. Remove drive belt shield.
2. Loosen idler pulley bolt (1).
3. Slide the idler pulley (2) up the chain tensioner rail to
tighten the belt. Pry it upwards and snug the idler pulley
bolt. Measure the deflection and adjust as required.
4. Tighten the idler pulley so that deflection at the top of the
belt is 1/2"–3/4" (12 mm–19 mm).
