FINAL ADJUSTMENTS
CONVEYOR PINTLE CHAIN TENSION
To check the conveyor chain tension, see whether the
chain is visible in the chain tension port. If the chain is
too tight, it will be above the port; if too loose, it will be
below the port.
If Conveyor Chain Is Too Loose
1. Loosen the two bearing mounting bolts on each
side of the conveyor idle roller at the cab end of
the hopper.
2. Loosen the jam nut on one of the idler take‑up
bolts. Tighten the take‑up bolt by turning it
clockwise while holding the jam nut. Repeat with
the opposite take-up bolt, tightening equally on
both passenger's side and driver's side until the
chain is in the middle of the chain tension port.
3. Tighten the bearing mounting bolts to
30 ft‑lb 40.7 N·m). Tighten the tensioner jam nuts.
If Conveyor Chain Is Too Tight
1.
Loosen the jam nuts on both sides. Back off the
idler take‑up bolt evenly on both sides. Then
loosen the bearing mounting bolts on both sides.
2. Adjust the chain tension until the chain is visible in
the chain tension port.
3. Tighten the jam nuts. Tighten the bearing
mounting bolts to 30 ft‑lb 40.7 N·m).
