6.
Turn the adjusting bolt to give a minimum of 1 inch (2.5 cm) of clearance
between the paddle shaft and lifter wheels. This dimension is critical, espe-
cially when using rubber bumpers (rock struts).
NOTE:
It may be necessary to loosen the paddle shaft chain on both sides to
provide slack to allow the paddle shaft to move. See section 7.21.1, Paddle
Shaft Chain.
7.
Tighten the shaft mounting bolts and the jam nuts on the adjusting bolts.
Set the same dimension (B), shown in Figure 7
-
17, on both sides and se-
cure the mounting fasteners in position. On wide
-
frame harvesters, set the
same dimension (B) on the center mount as on the outer mounts.
8.
For harvesters equipped with rock struts, place a 4 x 4 inch (8.9 x 8.9 cm)
block of wood under one of the lifter wheels and lower the entire weight of the machine down on
this strut.
9.
The rim should clear the shaft by at least ½ inch (1.3 cm). If the rim is touching the shaft, raise the
paddle shaft until it clears by at least ½ inch (1.3 cm).
10.
If the bumper compression is adjusted, raise the wheel off the block and lower it again. Check the
clearance again.
11.
Repeat the procedure with each set of lifter wheels. This will ensure that none of the wheels will
contact the paddle shaft.
12.
Close the access doors before starting the machine.
7.9 Paddles
The paddles are adjustable, in and
out, depending on wet or dry harvest
conditions. Moving paddles toward
the wheels will clean the rim of the
wheel and aid in rotation. Adjusting
the paddles in or out should be done
after making any paddle shaft height
adjustments.
IMPORTANT:
Excess contact may
stop lifter wheel rotation.
1.
Loosen lock nuts (C), shown in Fig-
ure 7
-
18, on the paddle mounts.
2.
Move the paddles to the desired
position.
3.
Tighten lock nuts (C).
