Maintenance
Exhaust Diesel Particulate Filter (DPF)
Regeneration
Collected soot particles in the Diesel Particulate Filter (DPF)
are automatically burned off through normal regeneration
(initiated by normal exhaust heat during the normal operation
of the vehicle). If conditions for normal regeneration cannot be
achieved, it may be necessary to perform a parked regeneration
as indicated by the Instrument Panel Gauge Cluster warning
indicators See the Parked Regeneration Procedure in
SECTION
9 — DRIVING .
Cleaning
If on-vehicle regeneration is unsuccessful at removing soot from
the DPF, the DPF may need to be removed from the vehicle and
be cleaned with the appropriate machinery and processes.
Ash residue in the DPF comes primarily from fuel and oil
additives and will not burn or pass through the DPF. Ash residue
accumulates very slowly in the DPF, but must eventually be
removed to prevent excessive exhaust backpressure.
If the
DPF needs to have nonregenerable soot or the ash residue
removed, please take the vehicle to an IC Bus dealer.
Transmission
Transmission Fluid Level
1. Hot fluid level
2. Cold fluid level
• Check fluid level with the parking brake applied, the
engine running at idle speed, and the transmission in
neutral.
Consider the transmission fluid temperature
when determining the correct level.
• When the transmission fluid is cold, the fluid level should
fall within the COLD run band. When the transmission
fluid is hot, the fluid level should fall within the HOT
run band. Add fluid as required.
Do not overfill or the
transmission will overheat.
• Check the shift linkage for proper operation.
• Check operation of transmission neutral safety switch.
Try to start the vehicle in all shift selector positions. The
starter should only operate when the shift selector is in N
(Neutral), or P (Park), if supplied.
• Refer to the Lubrication and Maintenance Interval
Chart and the Lubricant and Sealer Specifications
Chart in the Maintenance Intervals and Specifications
section for information on automatic transmission fluids
and fluid and filter change intervals.
