Danger: Before repairing or adjusting any
part of the corn head, engage the feeder
house lift cylinder safety stops, set the
parking brake, turn off the combine
engine and remove the key and hang a
warning sign on the operator’s platform.
Failure to do so could result in serious
injury or death.

6.7.1 – Gathering Chain Tension

The gathering chain tension is maintained by a spring-
loaded tensioner (A). The spring (B) is housed inside a
stationary tube with a spacer inside the spring. The
spacer serves as a stop to keep the idler sprocket from
retracting too far.

Checking Chain Tension:

1) Pull the gathering chain (C) outwards,
at the location of the red arrow, until
the tensioning fork (D) bottoms out.
2) Mark the tensioning fork (D) where it
enters the gathering chain guide (E).
3) Release the gathering chain and
measure the distance between the
mark made in Step 2 and the gathering
chain guide (E).
a. Distance between the mark and the
gathering chain guide should be 1/4"
to 5/16” (6mm to 8mm).

Tensioning:

1) Check the gathering chain tension as outlined
above.
2) Loosen the jamb nut (F).
3) Tighten or loosen the tensioning bolt (G).
a. Tighten = more chain tension
b. Loosen = less chain tension
4) Re-check the gathering chain tension as
outlined above.
5) Once the gathering chain tension is correct
tighten the jamb nut (F).
