require different procedures for checking and
making any necessary adjustments. Refer to
the appropriate section for your particular
header.
I. A30-S SINGLE KNIFE
a. Open shield on header RH side.
b. Reel drive belts (A) should deflect 3/16 in.
(4 mm) when a load of 8–12 lbf (35–40 N) is
applied to each belt at mid-span.
c. Reel drive chain (B) slack should be 1/4 in.
(6 mm).
d. Close
shield.
e. Open shield on header LH side.
f. Sickle drive belt (C)
should deflect 1/4 inch
(6 mm) when a load of 20 lbf (80 N) is applied at
mid-span).
g. Auger drive chain (D)
deflection at mid-span
should be 1/4 inch (6 mm).
h. Auger drive belts (E) belt should deflect 3/16 in.
(4 mm) when a load of 8–12 lbf (35–40 N) is
applied to each belt at mid-span.
i. Close
shield.
j. Proceed

STEP 20B. AUGER STRIPPER
BAR CLEARANCE
.
II. A40-D DOUBLE KNIFE
a. Open shield on header RH side.
b. Sickle drive timing belt (M) should deflect
0.55 inch (14 mm) when a load of 5–6.5 lbf
(22–30 N) is applied at mid-span).
c. Open shield on header LH side.
d. Sickle drive timing belt (N) should deflect
0.55 inch (14 mm) when a load of 5–6.5 lbf
(22–30 N) is applied at mid-span).
e. Sickle drive V-belts (O) should deflect 3/16 in.
(4 mm) when a load of 8–12 lbf (35–40 N) is
applied to each belt at mid-span.
f. Close
shields.
