Maintenance
DPF Service
The DPF (Diesel Particulate Filter) is designed to burn
trapped particulate matter automatically or via operator-
induced regeneration. The longer the DPF runs, the
more ash (burnt residue) is collected on the filter. Too
much residue adversely affects DPF performance,
therefore, see your authorized dealer for professional
cleaning (or replacement) if needed.
Do not be alarmed if you notice white exhaust from the
exhaust pipe at start-up or when speeding up. White
exhaust or water may come out during cold weather or
after long-hour idling due to condensation.
If DPF regeneration occurs frequently, i.e., five hours
or shorter, on a routine basis, change the oil. If this
condition continues after an oil change, contact your
authorized dealer for service. (Refer to your Engine
Operator’s Manual for service information.)
Don’t idle machine any longer than
necessary as too much idling can cause soot to build
up in the Diesel Particulate Filters (DPF), requiring
more frequent regeneration.
To reduce the amount of soot and
maximize DPF efficiency, use API-CJ4 (or ACEA-E9
European equivalent) engine oil. Running the
engine at 1800 RPMs will also provide more efficient
operation and allow automatic regeneration more
efficiently while paving.
Engine Drive Belt
Adjust the engine drive belt every 250 service hours
and replace it every 500 hours. Regardless of the
maintenance interval, the engine fan belt should be
replaced if it appears frayed or cracked. This belt drives
the alternator and the cooling fan.
NOTE: If the fan belt is loose or damaged, and/or the
fan is damaged, it can result in overheating
or insufficient charging. Replace the fan
belt and any other damaged components
immediately.
Engine must be turned off and the key
removed before checking, adjusting or replacing the
fan belt to avoid personal injury or even death.
To adjust or replace the belt:
1. Turn off engine and remove the key. Block the
wheels to prevent movement while working on the
machine.
2. Remove the safety shield.
(Figure 5-15)
3. Apply moderate thumb pressure to the belt between
the pulleys to gauge tension.
4. If tension is incorrect, loosen the alternator
mounting bolts and place a lever between the
alternator and the engine block.
•
If adjusting the belt, pull the alternator out until
the deflection of the belt (when pressed in the
middle of the span) falls within .39 to .47 inches
(10 to 20 mm).
•
If replacing the belt, remove worn belt and
replace with new fan belt.
5. Retighten the alternator bolts and reinstall safety
shield.
