F. CONDITIONER ROLLS
DANGER
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. Lower header fully, stop engine, and remove
key.
b. Check that nut (B) is tight, and top of nut (B) is
at 2 on the decal (A).
c. If required, adjust the gap by loosening nut (B),
and turning adjuster (C). Re-tighten nut (B).
NOTE
When adjusting roll gap, be sure that the
decal reading is the same on both sides of
the conditioner roll to achieve consistent
intermesh across the rolls.
d. Loosen bolt (D), and rotate cover (E) to expose
access port (F).
e. Check roll timing by examining distance
‘X’
at
each end of the rolls (F). Each steel bar on one
roll should be centered between two bars of the
other roll, so that distance ‘X’ is 0.5 inches
(12 mm).
f. If required, adjust the roll timing as follows:
1. Loosen four bolts (G) in slots of yoke plate
on lower roll universal shaft.
2. Turn rolls to achieve “best” timing.
3. When roll timing is satisfactory, tighten bolts
(G) to secure the position.
4. Reposition cover (E), and tighten bolt (D).
g. Check oil level in conditioner gearbox. Oil is at
required level when it runs out of check plug (H).
