7.11.4.1 Tension

IMPORTANT
To prolong drive life, do not over-tighten
belt. Belt slippage is used to protect the
auger in an overload situation.
Minor belt tension adjustments may be
made without affecting chain tension. For
major adjustments, like after repositioning
reel or auger, adjust chain tension before
belt tension.
Adjust auger drive belts (A) tension as follows:
a. Open LH end shield.
b. Loosen three bolts (B).
c. Loosen jam-nut on adjuster bolt (C).
d. Turn adjuster bolt (C) so that each belt deflects
3/16 in. (4 mm) at mid-span when a load of 8-12
lbf (35-40 N) is applied to each belt.
e. Tighten bolts (B) and jam-nut at (C).
Re-adjust tension of new belts after about
5 hours of operation.
f. Close shield before engaging header.
