Revision A
Tightening Caster Wheel Anti-Shimmy Dampeners
The windrower
’
s anti-shimmy dampeners mitigate the tendency of caster wheels to shake. They may require tightening
from time to time.

Figure 5.223: Anti-Shimmy Dampener
Each caster is equipped with a fluid-filled anti-shimmy
dampener (for example, dampener [A]).
Mounting bolts (B) should be checked periodically to ensure
that they are tight. For the inspection interval, refer to .
•
The inboard bolt must be tightened to 135 Nm (100 lbf·ft).
•
The outboard bolt must be tightened to 115 Nm (85 lbf·ft).
Ballast Requirements
Adding fluid ballast to the windrower
’
s caster tires will improve the windrower
’
s stability when it is paired with a heavy
header. Tire ballast may only be needed for certain header-windrower combinations in certain types of terrain.
With respect to ballast capacity, a tire is considered to be
“
full
”
of ballast fluid when 75% of the inner volume of the tire is
occupied by ballast fluid, or else when the ballast fluid is level with the wheel
’
s valve stem when the stem is at the
12 o
’
clock position while the windrower is on level ground. When adding ballast fluid to the caster wheels, always add an
identical amount to each wheel. The caster wheels can safely hold any volume of ballast fluid up to and including their
maximum capacity, as specified in the table below.

44. The weights provided in this column rely on the assumption that the tires will be filled with a standard mixture of
calcium chloride and water. If you intend to fill the tire with only water (for example, in regions where the ambient
temperature does not fall below freezing), then multiply the relevant fill weight specified in this column by 0.8 to
calculate the weight of both tires when they are filled with water alone.
