6.7.2 – Replacing Gathering Chains

It is important to inspect the gathering chain
periodically to determine the amount of stretch. As the
gathering chain wears, it will begin to stretch. When
the gathering chain reaches three percent stretch it
has reached the end of its life.

Note: The gathering chains should not continue to be
run after they reach three percent total stretch. Failure
to replace the gathering chains can result in breakage
of the gathering chain and the possibility of the
gathering chain entering the combine. Damage to the
tensioning fork and gathering chain guide can also
occur.

Inspection for Replacement:

i. Tension the gathering chain.
See Section 6.7.1
ii. Measure the distance (A)
between the rear surface of
tensioner fork and the front
surface of the gathering chain
guide.
a. New gathering chains will have an
approximate measurement of 1 7/16”
(37mm).
b. A gathering chain with three percent
stretch will have an approximate
measurement of 2 5/8” (67mm).
