a. Open LH endshield.
b. Loosen auger drive chain (A) as follows:
1. Loosen three bolts (B).
2. Loosen jam nut on adjuster bolt (C), and
turn adjuster bolt (C) to loosen chain (A).
c. Loosen four nuts (D).
d. Loosen jam nuts on adjuster bolts (E), and turn
bolts (E) to adjust auger vertical position.
e. Tighten jam nuts and nuts (D).
f. Tighten auger drive chain (A) as follows:
1. Turn adjuster bolt (C) to tighten chain (A).
Deflection at (A) should be 1/4 in. (6 mm).
2. Tighten jam nut on bolt (C).
g. Check auger drive V-belt (F) tension. Each belt
should deflect 3/16 in. (4 mm) at mid-span when
a load of 8–12 lbf (35–40 N) is applied to each
belt. If necessary, adjust as follows:
1. Loosen jam nut on adjuster bolt (G).
2. Turn adjuster bolt (G) to achieve tension as
per above.
3. Tighten jam nut at (G), and tighten bolts (B).
h. Open RH endshield.
i. Loosen reel drive belts (K) as follows:
1. Loosen jam nut on adjuster bolt (H) and nuts
(J).
2. Turn adjuster bolt (H) to loosen reel drive
belts (K).
j. Loosen three nuts (L).
k. Loosen jam nuts on adjuster bolts (M), and turn
bolt (M) to adjust auger vertical position.
l. Tighten jam nuts and nuts (L).
m. Tighten belts (K) as follows:
1. Turn adjuster bolt (H) to move pulley so that
each belt (K) deflects 3/16 in. (4 mm) when
a load of 8–12 lbf (35–40 N) is applied to
each belt at mid-span.
2. Tighten jam nut on adjuster bolt (H) and nuts
(J).
