6.12.2 Diesel Exhaust Fluid Supply Module Filter
The supply module filter is designed to prevent debris that may be suspended in the diesel exhaust fluid (DEF) from
entering the system. Permanent damage to—and premature failure of—the DEF supply module can result from fluid
debris.
Checking Diesel Exhaust Fluid Supply Module Filter
Regular inspection of the diesel exhaust fluid (DEF) supply module filter ensures long-lasting windrower performance.
1. Locate aftertreatment DEF supply module (A) on the inside
of the right platform by the engine oil dipstick.
2. Inspect the area around the seal and vent of aftertreatment
DEF supply module filter cap (A) for signs of leakage.
3. DEF fluid leaves a white deposit when dry. If there is
evidence of leaking, remove the supply module filter, and
clean and inspect it before replacing it. For instructions,
refer to
Cleaning and Inspecting Supply Module Filter, page
361.
Removing Supply Module Filter
The windrower's diesel exhaust fluid (DEF) supply module filter may need to be removed for replacement or inspection.
WARNING
Batteries emit explosive gases. To reduce the possibility of personal injury, always ventilate the compartment before
servicing the batteries. To reduce the possibility of electrical arcing, remove the negative (–) battery cable first and
attach the negative (–) battery cable last.
