Maintenance Procedures
Replacing Engine Oil Filters
1.
Full-Flow Oil Filter
2.
Centrifugal Bypass Oil Filter
3.
Oil Filter Cap Lock
Your engine is equipped with a full-flow
oil filter and centrifugal bypass oil filter.
Both filters are designed to capture
contaminants and remove deposits
from the oil to prolong the life of
internal moving components. Always
use quality engine lubricating oils in
conjunction with the appropriate oil
drain and filter change intervals. Refer
to “Maintenance Schedule” beginning,
on page 5-4, for the recommended oil
and filter change service interval.
Oil Filter Removal Preparation
1. Disconnect the chassis battery
cable at the negative battery
terminal.
CAUTION
Before beginning to remove and/or
disconnect any components, wait at
least 5 minutes after the key switch
is turned OFF for the aftertreatment
Diesel Exhaust Fluid (DEF) dosing
system to purge the DEF from the
system. The DEF system purges to
prevent damage from freezing. Fail-
ure to comply may result in equip-
ment or property damage.
