DEF Dosing Unit Filter
The DEF dosing unit filter is a 10-micron filter designed to
prevent foreign objects, that may be suspended in the DEF,
from entering the dosing system.
Debris can cause permanent damage and premature failure
to either the aftertreatment DEF dosing unit or the
aftertreatment DEF dosing valve.
The filter should be replaced every 200,000 miles or 4500
hours of crane operation.
The aftertreatment DEF dosing unit filter consists of the
following components:
(1) Aftertreatment DEF Dosing Unit Filter Cap
(2) Aftertreatment DEF Dosing Unit Filter Equalizing Element
(3) Aftertreatment DEF Dosing Unit Filter Element.
Initial Check
Inspect the area around the seal and vent of the
aftertreatment DEF dosing unit filter cap for signs of leakage.
DEF leaks leave a white deposit. If deposits are found, see
the Clean and Inspect for Reuse section in this procedure.
