DEF Dosing Unit Filter
The DEF dosing unit filter (Figure 7-11) 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 480,000 km (300,000
miles) or 6750 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.
