Poly V
-belt, Alternator, Air-
Conditioning Compressor Drive
and Coolant Pump Drive Install
Procedure to install poly v-belt, alternator,
air-conditioning compressor drive and
coolant pump drive engine belts.
Follow the steps below to install the poly v-
belt, alternator, air-conditioning compressor
drive and coolant pump drive belts:
1. Place the new poly V-belt over the
pulleys, positioning the new belt so
that it falls into all the belt pulley
grooves.
NOTE
When installing the belts do not wrap
belt around the
tensioner until after the
belt has been wrapped around all oth-
er pulleys and idlers.
2. After installing the belt, carefully
allow the belt tensioner to spring
back to its normal position. If the
tensioner had been temporarily
blocked, relieve tensioner pressure
enough to remove the locking pin,
then allow the tensioner to spring
back to its normal position.
3.
Reinstall the fan drive poly V-belt
as previously described in Poly V

on page 70.
4. Reconnect the electrical ground
wire to the battery.
Aftertreatment System
Diesel Particulate Filter Service
Strategy
Customers have two options when
maintaining their Diesel Particulate Filter.
Both strategies are shown on the
maintenance schedule but only one
strategy may be used. They are not
interchangeable.
1. Dry Cleaning strategy - This
strategy requires cleaning of ash at
the stated interval. Once the unit is
cleaned, it cannot be switched to
the wet cleaning strategy interval.
See Diesel Particulate Filter (DPF)
Dry Cleaning on page 72 for the
service procedure.
2. Wet Cleaning strategy - This
strategy requires wet cleaning the
unit at the stated interval. A wet
cleaned unit from an authorized
PACCAR dealer may either
continue to use the wet
cleaning strategy or switch to use
the dry cleaning strategy.
Diesel Particulate Filter (DPF) Dry
Cleaning
Maintenance tasks to clean the diesel
particulate filter.
Perform this maintenance procedures
according to the Preventative Maintenance
Schedule.
NOTE
The aftertreatment DPF dry clean/wet
clean interval is
based on the use of
lubricating oils that meet the SAE
10W30 API CK–4/CJ-4 oil specifica-
tion.
