MAINTENANCE AND SERVICING
Cleaning and Inspecting the Supply Module Filter
NOTE:
If there is the possibility that contaminated diesel exhaust fl uid (DEF) has gone through the DEF supply system,
check the DEF fi lter prior to discarding the fi lter.
1. Check the diesel exhaust
fi lter for evidence of contaminated DEF. Use visual and aroma characteristics of the
fi lter to determine if contaminated
fl uid has passed through the dosing system.
2. Inspect the diesel exhaust
fi lter for debris.
3. Discard the
fi lter element and the equalizing element.
4. Inspect the aftertreatment DEF supply module
fi lter cap for cracks or holes.
5. Check the condition of the threads on the aftertreatment DEF supply module cap.
6. Replace the aftertreatment DEF supply module cap, if threads are damaged.
7. If cap threads are damaged, inspect the aftertreatment DEF supply module threads.
8. Replace the entire aftertreatment DEF supply module, if threads of aftertreatment DEF supply module are
damaged.
9. Clean the aftertreatment DEF supply module cap and threads on the supply module with warm water and
clean cloth.
Installing the Supply Module Filter
1. Slide the DEF fi lter equalizing element (A) into the DEF
fi lter cartridge (B).
2. Insert the assembly into the aftertreatment DEF
dosing unit (C).
3. Install cap (D) and torque to 20 N · m (15 ft · lbf).
NOTE:
The aftertreatment DEF dosing system will not prime
until the correct selective catalytic reduction (SCR)
temperatures are reached. To verify that there are no
DEF leaks, test drive the windrower for a minimum of
15 minutes to get the SCR system up to temperature.
4. Operate the engine and check for leaks.
