7.11.2 Auger Drive Belts: A30-D
7.11.2.1 Adjusting Tension
IMPORTANT
To prolong drive life, do NOT over-tighten
belt. Belt slippage is used to protect the
auger in an overload situation.
NOTE
Minor belt tension adjustments may be
made without affecting chain tension.
For major adjustments, like after
re-positioning reel or auger, adjust chain
tension BEFORE belt tension.
Adjust auger drive belts (A) tension as follows:
CAUTION
Stop engine, and remove key from ignition
before leaving Operator’s seat for any
reason. A child or even a pet could engage
an idling machine.
a. Open LH endshield.
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).
NOTE
Readjust tension of new belts after
about 5 hours of operation.
f. Close shield before engaging header.
7.11.2.2 Removing
a. Open LH endshield.
b. Remove auger drive chain (D) as follows:
1. Loosen nut (E) on idler sprocket support.
2. Turn adjuster bolt (F) to loosen chain (D).
3. Remove chain from small sprocket.
c. Loosen three bolts (B). See illustration opposite.
d. Loosen jam nut on adjuster bolt (C).
e. Turn adjuster bolt (C) to loosen auger drive
belts (A).
f. Remove belts (A).
7.11.2.3 Installing
IMPORTANT
Auger drive belts are a matched set.
Replace both drive belts even if only one
needs replacing.
a. Position auger drive belts (A) as shown in
previous column.
b. Turn adjuster bolt (C) so that belts (A) deflect
3/16 in. (4 mm) at mid-span when a load of
8–12 lbf (35–40 N) is applied to each belt.
c. Tighten bolts (B), and jam nut at (C).
d. Install auger drive chain (D) as follows:
1. Position chain on small sprocket.
2. Turn adjuster bolt (F) to give 0.2 in. (5 mm)
slack at mid-span of chain. Tighten nut (E)
on idler sprocket support.
3. Rotate auger, and check chain for slack at
tightest point. Readjust position of idler
sprocket to achieve required slack.
e. Close endshield.
