Cummins ISL9 to replace the ISC8.3l
ISL9 to Replace ISC8.3 in 2013
For years, the ISC8.3 has been a staple of the bus market. Starting in 2013, Cummins is incorporating all of the lower ratings from the ISC8.3 into the ISL9, and is discontinuing the ISC8.3 platform. Bus operators moving up to the ISL9 will find that it has the same great reliability and durability as the ISC8.3, since 95 percent of the components from the ISC8.3 are identical to those of the larger-displacement ISL. Operators will also see better fuel economy from the ISL9 in 2013 versus their 2012 ISC8.3 engines.
Ratings for the 2013 ISL9 range from 260 hp (194 kW) with 720 lb-ft (976 N•m) of peak torque to 350 hp (261 kW) and 1000 lb-ft (1356 N•m) in school bus applications. Transit buses will have a choice of 280 hp (209 kW) with 900 lb-ft (1220 N•m) of peak torque or 330 hp (246 kW) with 1100 lb-ft (1491 N•m) of peak torque, while shuttle buses have a selection of seven ratings from 260 hp to 370 hp (194-276 kW) with 720 lb to 1250 lb-ft (976-1695 N•m) of peak torque.
The extra torque generated by the ISL9 will provide bus operators better response in stop-and-go traffic and on highway entrance ramps versus buses powered by the current ISC8.3 engine. If you have any questions about this change, please contact your Cummins representative.

The same items are required to be inspected by each document. FMCSA's and CVSA's out-of-service criteria are intended to be used in random roadside inspections to identify critical vehicle inspection items and provide criteria for placing a vehicle(s) out-of-service. Avehicle(s) is placed out-of-service only when by reason of its mechanical condition or loading it is determined to be so imminently hazardous as to likely cause an accident or breakdown, or when such condition(s) would likely contribute to loss of control of the vehicle(s) by the driver. A certain amount of flexibility is given to the inspecting official whether to place the vehicle out-of-service at the inspection site or if it would be less hazardous to allow the vehicle to proceed to a repair facility for repair. The distance to the repair facility must not exceed 25 miles. The roadside type of inspection, however, does not necessarily mean that a vehicle has to be defect-free in order to continue in service.In contrast, the appendix G inspection procedure requires that all items required to be inspected are in proper adjustment, are not defective and function properly prior to the vehicle being placed in service.Differences Between the Out-of-Service Criteria and FMCSA's Annual Inspection1. Brake System.The appendix G criteria rejects vehicles with any defective brakes, any air leaks, etc. The out-of-service criteria allows 20% defective brakes on non-steering axles and a certain latitude on air leaks before placing a vehicle out-of-service.2. Coupling Devices.Appendix G rejects vehicles with any fifth wheel mounting fastener missing or ineffective. The out-of-service criteria allows up to 20% missing or ineffective fasteners on frame mountings and pivot bracket mountings and 25% on slider latching fasteners. The out-of-service criteria also allows some latitude on cracked welds.3. Exhaust System.Appendix G follows Section 393.83 verbatim. The CVSA out-of-service criteria allows vehicles to exhaust forward of the dimensions given in Section 393.83 as long as the exhaust does not leak or exhaust under the chassis.4. Fuel System.Same for Appendix G and the out-of-service criteria.5. Lighting Devices.Appendix G requires all lighting devices required by Section 393 to be operative at all times. The out-of-service criteria only requires one stop light and functioning turn signals on the rear most vehicle of a combination vehicle to be operative at all times. In addition one operative head lamp and tail lamp are required during the hours of darkness.6. Safe Loading.Same for both Appendix G and the out-of-service criteria.7. Steering MechanismSteering lash requirements of appendix G follows the new requirements of §393.209.8.

The same items are required to be inspected by each document. FMCSA's and CVSA's out-of-service criteria are intended to be used in random roadside inspections to identify critical vehicle inspection items and provide criteria for placing a vehicle(s) out-of-service. Avehicle(s) is placed out-of-service only when by reason of its mechanical condition or loading it is determined to be so imminently hazardous as to likely cause an accident or breakdown, or when such condition(s) would likely contribute to loss of control of the vehicle(s) by the driver. A certain amount of flexibility is given to the inspecting official whether to place the vehicle out-of-service at the inspection site or if it would be less hazardous to allow the vehicle to proceed to a repair facility for repair. The distance to the repair facility must not exceed 25 miles. The roadside type of inspection, however, does not necessarily mean that a vehicle has to be defect-free in order to continue in service.In contrast, the appendix G inspection procedure requires that all items required to be inspected are in proper adjustment, are not defective and function properly prior to the vehicle being placed in service.Differences Between the Out-of-Service Criteria and FMCSA's Annual Inspection1. Brake System.The appendix G criteria rejects vehicles with any defective brakes, any air leaks, etc. The out-of-service criteria allows 20% defective brakes on non-steering axles and a certain latitude on air leaks before placing a vehicle out-of-service.2. Coupling Devices.Appendix G rejects vehicles with any fifth wheel mounting fastener missing or ineffective. The out-of-service criteria allows up to 20% missing or ineffective fasteners on frame mountings and pivot bracket mountings and 25% on slider latching fasteners. The out-of-service criteria also allows some latitude on cracked welds.3. Exhaust System.Appendix G follows Section 393.83 verbatim. The CVSA out-of-service criteria allows vehicles to exhaust forward of the dimensions given in Section 393.83 as long as the exhaust does not leak or exhaust under the chassis.4. Fuel System.Same for Appendix G and the out-of-service criteria.5. Lighting Devices.Appendix G requires all lighting devices required by Section 393 to be operative at all times. The out-of-service criteria only requires one stop light and functioning turn signals on the rear most vehicle of a combination vehicle to be operative at all times. In addition one operative head lamp and tail lamp are required during the hours of darkness.6. Safe Loading.Same for both Appendix G and the out-of-service criteria.7. Steering MechanismSteering lash requirements of appendix G follows the new requirements of §393.209.8. SuspensionAppendix G follows the new requirements of §393.207 which does not allow any broken leaves in a leaf spring assembly. The out-of-service criteria allows up to 25% broken or missing leaves before being placed out-of-service.9. FrameThe out-of-service criteria allows a certain latitude in frame cracks before placing a vehicle out-of-service. Appendix G follows the new requirements of 393.201 which does not allow any frame cracks.10. TiresAppendix G follows the requirements of 393.75 which requires a tire tread depth of4/32inch on power unit steering axles and2/32inch on all other axles. The out-of-service criteria only requires2/32inch tire tread depth on power unit steering axles and1/32inch on all other axles.11. Wheel and RimsThe out-of-service criteria allows a certain amount latitude for wheel and rim cracks and missing or defective fasteners. Appendix G meets the requirements of the new 393.205 which does not allow defective wheels and rims non-effective nuts and bolts.12. Windshield GlazingThe out-of-service criteria places in a restricted service condition any vehicle that has a crack or discoloration in the windshield area lying within the sweep of the wiper on the drivers side and does not address the remaining area of the windshield. Appendix G addresses requirements for the whole windshield as specified in 393.60.13. Windshield WipersAppendix G requires windshield wipers to be operative at all times. The out-of-service criteria only requires that the windshield wiper on the driver's side to be inspect

Cummins 8.3l DPF Crankcase pressure
Cummins CNG
Cummins Westport Inc. has begun development on the ISB6.7 G, a mid-range 6.7 liter natural gas engine designed to meet the increasing demand for on-highway vehicles powered by natural gas. As a leading supplier of natural gas engines, Cummins Westport says it will continue to expand its product range to supply the growing demand for natural gas engines.
The ISB6.7 G engine will be based on the Cummins ISB6.7 diesel engine and will use Cummins Westport's spark-ignited, stoichiometric cooled exhaust gas recirculation (SEGR) technology, the company says. Exhaust aftertreatment will be provided by a maintenance-free three-way catalyst. Cummins Westport says the engine will run on compressed natural gas (CNG), however, the natural gas may be stored on the vehicle in liquefied natural gas (LNG) state or as CNG. The ISB6.7 G is expected to be in production by 2015 and will be designed to meet Environmental Protection Agency (EPA) and California Air Resources Board (CARB) regulations in force at the time of launch, Cummins says.

ADEQ Releases Schools Chemical Management Toolkit to Assist Schools in Maintaining Safe Classroom Environment
Subject: [ADEQ Media] ADEQ Releases Schools Chemical Management Toolkit to Assist Schools in Maintaining Safe Classroom Environment
This announcement is for informational purposes only. Please do not reply to this e-mail. Questions may be directed to the contact provided in each notice. Thank you.
PHOENIX (Sept. 27, 2012) – Arizona Department of Environmental Quality officials announced today the release of a 60-page schools chemical management toolkit publication to assist school districts throughout the state in managing chemicals used at schools.
An online version of the toolkit is available in English at http://www.azdeq.gov/ceh/download/sc_toolkit.pdf and in Spanish at http://www.azdeq.gov/ceh/download/sc_toolkit-SP.pdf
The toolkit was developed to provide Arizona schools with basic information and resources needed to remove unnecessary, outdated or unknown chemicals from school labs and storage places. It provides guidance to prevent chemical mismanagement of incidents in schools and also serves as an educational tool to heighten awareness of the importance of proper chemical management.
"This is an important compilation of guidelines, resources and procedures to help schools around the state effectively oversee the use of chemicals and make sure that students and school personnel are protected," said ADEQ Director Henry Darwin. "When chemicals are mismanaged they create risk from spills, fires and other accidental exposures in and around schools."
The toolkit provides a roadmap for a school district or individual school to establish a school chemical management program and avoid hazardous chemical incidents. The program identifies, manages and prevents hazards through all stages of chemical purchasing, storage, use and disposal.
The release of the toolkit follows on the heels of a successful ADEQ-sponsored cleanup last month at three schools in the Nogales Unified School District funded by a $54,716 grant from the U.S. Environmental Protection Agency. More than 200 pounds of chemicals were collected and disposed of in an environmentally safe manner.

Donaldson DPF LNF LXF Pre Filters
Do you want to ensure your Donaldson DPF performs as well as possible? Consider installing a new pre-filter. The purpose of the pre-filter in the Donaldson LNF/LXF is to oxidize particulate matter (PM) and generate NO2. The NO2 generated in the pre-filter section oxidizes PM in the DPF section. The pre-filter can reduce up to 30% of the PM removed by the entire system. A properly functioning pre-filter can extend the life of the DPF. Engine malfunctions such as leaking fuel injectors or turbochargers can significantly reduce the effectiveness of the pre-filter. Because the pre-filter is the first line of defense against upstream engine component failures, keeping a replacement pre-filter on-hand can prevent vehicle downtime. The pre-filter should be replaced in cases of engine component failure and/or damaged DPF sections to ensure the LNF/LXF functions properly.
To assist in assuring proper pre-filter performance, for a limited time DCI is offering discounts on LNF/LXF pre-filters plus free shipping on orders of 5 pcs or more.

DPF, CARB, CDTI, Diesel Particulate Filters,
Slowed DPF and related after-treatment sales in California?
An article written by
Written by Michelle Fisher |
Tuesday, 11 September 2012 13:41 |
Pulled from “School Transportation News”
Clean-tech emissions control company Clean Diesel Technologies Inc. today announced that its sales so far this year are consistent with the results of a survey by the Manufacturers of Emission Controls Association, which revealed a “slow pace” of diesel particulate filter sales under the mandatory California Truck and Bus Regulation.
According to results released last month, the total number of verified DPFs sold by MECA member companies for in-use, on-road heavy-duty diesel vehicles operating in California, including school buses, is 3,030 for the first half of 2012.
Retrofit manufacturers such as CDTi were expecting this number to be much higher due to the requirements of the California Air Resources Board (CARB) in-use truck and bus regulation. Under the regulation, CARB projected that approximately 12,000 filters would be installed in 2012 to meet a Jan. 1, 2013 compliance deadline and about 66,000 would be installed from 2011 to 2015. Yet the 3,030 verified DPFs sold between Jan. 1 and June 30 is only half of the projected amount.
CDTi said this could be attributable to the level of operator education and the intensity of state enforcement actions. Working with the California Highway Patrol and other agencies, the CARB deployed inspectors throughout the state in August, focusing on truck stops, fleet facilities, weigh stations and other areas where diesel vehicles are present to ensure full compliance with the regulation’s requirements.
“The rate of verified DPFs sold has been below our and the industry’s expectations. However, while we have been successful in winning fleet operator business, we expect the trends to continue through the third quarter,” said Craig Breese, chief executive officer of CDTi. “We trust that the targeted and coordinated efforts by multiple state agencies will stimulate operators to initiate steps to comply with the Jan. 1, 2013 deadline and drive sales in the fourth quarter and beyond.”
CDTi, a manufacturer and distributor of emissions control systems and products, also stated that its product portfolio would expand further with pending CARB approvals.

Allison Transmission PROGNOSTICS - School Bus Transmissions
New MD and HD Allison Transmission PROGNOSTICS Information, be prepared when your driver calls in with the warning or the Tech completes a service and needs to reset the data.....
Trademark of Allison Transmission, Inc.
Eliminate Unnecessary Oil and Filter Changes
Routine Maintenance Made Easier
As part of Allison Transmission’s continuous product
improvement initiative, all Allison fully automatic
transmissions are now available with prognostic
features
* at no additional charge.
Allison prognostics take the guesswork and hassle out
of scheduling routine vehicle maintenance to save you
time and money while providing maximum protection
for the transmission. That means less downtime, lower
life-cycle costs and, best of all, greater productivity for
your fleet.
Calibrated to the particular operating requirements
of the vehicle, Allison prognostics monitor various
operating parameters to determine and alert when a
specific maintenance function is required. Allison
approved TES 295 transmission fluid is required.
On-highway models only. Allison transmissions can be ordered
without Allison prognostics.
Allison prognostics alert
when service is due
How Allison prognostics work.
While Allison prognostics use sophisticated
electronic monitoring technology, they are
very user friendly.
When service is due for Allison
3000/4000 Series models,
a wrench icon on the shift
selector’s digital display alerts
the operator. And, similar to
checking fluid level and diagnostics, you
can check the status of all three prognostic
features simply by toggling through the shift
selector’s display.
1000/2000 Series models require either a
service light or J1939 text display to alert
the operator.
Accessing prognostics via Allison shift selectors.
When fluid is due for a change:
The wrench icon
(3000/4000 Series) or
service light (1000/2000
Series) is
illuminated and
stays on for two minutes
after the Drive range is
selected. Once the Oil Life
Monitor mode has been accessed via the shift selector, a number
between “0” and “99” will be displayed indicating the percentage
of fluid life remaining before a change is required.
When the filter(s) are due for a change:
The wrench icon or service
light
flashes on and off for
two minutes
after the Drive
range is selected. Once the
Fluid Life Monitor mode
has been accessed via the
shift selector, an “oK” or
“Lo” will be displayed. “oK” means the filter(s) does not need to be
changed, and “Lo” means the filter(s) needs to be changed.
When clutch maintenance is due:
The wrench icon or service
light
comes on and stays on
in all ranges. Once Transmission
Health Monitor
mode has been accessed via
the shift selector, an “oK”
or “Lo” will be displayed. “oK” means no clutch maintenance is
needed, and “Lo” means clutch maintenance is required.

IHC Navistar & SCR - School Bus application?
With all the posts about International looking to Cummins for their SCR emissions, I got to thinking is this just the Cummins packaged engine and SCR, or will IHC look to install the SCR on the Maxxforce engine?
My collected oil samples from the Maxxforce engine, school bus application has as much as 10% fuel dilution, there lies the problem I see..... If you take a look at some of the earlier posts, I show several examples of failed Aftertreatment and face-plugged units as well, all a result of soot or ........... Making its way down the exhaust. My thought is IHC will have a whole other can of worms on their hands if they marry the two products together, face plugging @ 7000 miles and failure after failure on the SCR as a result of the thin oil full of diesel making the trip down the pipe.

CAT Aftertreatment - Anyone having a problem?
First I have seen of this as face plugging is a maint. Issue, what are your thoughts for all brands?
Caterpillar Heavy Duty Engine Complaints and Investigation
Lieff Cabraser Heimann & Bernstein, LLP, is a national plaintiffs’ law firm that represents plaintiffs in cases involving defective vehicles, vehicle components, and other products.
We are investigating complaints by bus companies and other operators that Caterpillar heavy duty engines produced from 2008 to 2010 equipped with an exhaust regenerator are defective. The engines under investigation include the Caterpillar Cat C13 and C15 motor coach diesel engines with ACERT technology.
The complaints charge that the exhaust regenerator fails in ordinary use, leading to soot build up, clogged exhaust systems, and engine failure. It is further alleged that Caterpillar has failed to develop a lasting solution to the problem, resulting in continued engine failure even after the engine has been repaired. Bus companies and other operators have allegedly incurred substantial losses due to towing and repair charges, along with having to compensate or provide for alternative transportation to affected passengers.

SCR DEF added to your Diesel fuel Tank?
Do you know what damage could be done if SCR DEF (Diesel Exhaust Fluid) was accidentally added to the Diesel Fuel Tank?
What if Diesel Fuel was added to the DEF Tank?
SCR face plugging? Ruined SCR? Failed Engine?
The DEF fluid is very corrosive and once it makes its way into the fuel system the damage will cost you well into the thousands, what are you doing to prevent this from happening?
