Emergency Breakdown Service

Breakdowns never happen on a schedule. Thankfully, Peterson Trucks offers 24/7/365 emergency roadside service from all our locations in Oregon. When breakdowns strike, count on Peterson’s team of OEM-certified technicians and fleet of response vehicles to come to your driver’s aid.

And in the case that repairs cannot be completed on site, Peterson works with local towing vendors to bring your vehicle to our shop where it can be processed by our Accelerated Service Program. Our goal is to get your truck fixed, out of the shop, and back on the road as quickly as possible!

What to Expect when You Call

Calling during business hours? Follow the prompts on the automated system to your store’s service desk. Let the dispatcher or service clerk know what the issue is and where your truck can be found. We’ll send a tech out as soon as possible.

Calling afterhours? A third party answering service will gather your information and pass it along to the on-call tech. You’ll receive a call back from a member of our service team, and we will dispatch help to your location.

What to Expect from the Technician

Communication is at the core of our relationship with each and every customer. Our techs will be in touch before they arrive at your location. Their goal is to maintain the safety of you, your vehicle, and the motoring public.

Once on site, the technician will use a number of tools and resources to address the problem. This may include using specialized diagnostic equipment, or calling Navistar’s EBS Control Center, or technical communicators at Peterson University for additional expertise.

Your UpTime is our priority!

Peterson Trucks: Your Emissions Expert

With the approval of the Truck and Bus Regulation by the California Air Resources Board (CARB), new emissions standards for in-use on-road heavy-duty diesel vehicles are in effect, with additional compliance deadlines coming soon. From determining your compliance deadlines to helping you report your fleet to the Air Resources Board, Peterson is dedicated both to helping you understand CARB emissions requirements and providing you with the most up-to-date technology for meeting California emission standards.

What is the CARB Truck and Bus Regulation?

Applying to privately and publicly owned diesel trucks with a GVWR of over 14,000 pounds, this regulation required all applicable trucks to be fitted with a particulate matter (PM) filter by January 1, 2012. By the beginning of 2015, older trucks (with a 1995 model year engines or later) must be replaced with newer trucks. By 2023, all trucks in-service will be required to have 2010 model year engines or newer. The regulation is intended to reduce emissions of diesel particulate matter and oxides of nitrogen.

Existing Vehicle Compliance (Diesel Particulate Filters)

Our on-highway emissions experts are dedicated to helping you understand the latest state and federal regulations, and to finding the emissions solution that’s right for your fleet. Peterson Trucks is an authorized distributor of diesel particulate filters (DPF's) from multiple manufactures. As direct dealers of these products, we're often able to offer the technology at a lower price than other commercial truck dealers.

We're Here to Help - Information, Funding, Compliance Seminars

Contact us to learn what programs are available to help you comply with CARB emissions regulations. We periodically host CARB-sponsored training courses for fleet owners and managers.

Fluid Analysis

Keep Your Fleet Running at Peak Efficiency

Monitor the health of your fleet with Peterson's Fluid Analysis Lab Program. Fluid Analysis can provide early detection of mechanical problems, avoiding costly failures and extending the life of your trucks. Regular oil and coolant testing are excellent tools to help detect impending system failures and ensure that your equipment is being protected.

How can fluid analysis make a difference in your fleet?

Your trucks have been engineered to precise standards to ensure peak performance, and fluids are an important factor in this equation. Failed or worn parts can be analyzed to provide vital performance information, and fluids can tell a similar story. Help avoid large repair bills and costly downtime with Peterson's S•O•S and Coolant Analysis programs.

After processing, each report is carefully reviewed, the results explained, and (if required) recommendations are made. All of this is to ensure that Peterson Fluid Analysis is truly your value-added service.

Oil Analysis

  • Identifies the type of wear metal elements present, reported as PPM (parts per million)
  • When samples are taken at regular intervals, these elements can be trended to often spot the onset of a progression towards premature wear or failure
  • Element combinations help pinpoint problem areas. These combinations aid in the identification of the source of excessive wear
  • Monitor environmental contaminants, such as silicon/sodium, that indicate dirt entry into the system
  • Lower your overall coefficient of wear, ultimately extending the life of your component
  • 70% of all hydraulic system failures are caused by some form of contaminant
  • Particle count analysis is used to detect metallic and non-metallic impurities in oil, such as friction disc material or contamination, which are otherwise undetectable
  • Combined with wear-rate analysis, this provides a more comprehensive evaluation of hydraulic and powertrain component health
  • Determines lubrication properties of your oil
  • Infrared analysis is used to test for soot, sulphation, oxidation, and nitration, determines the extent of oil deterioration and if your oil is performing to spec
  • Fluid contaminants can degrade oil performance rapidly and are often signs of problems elsewhere that could require immediate attention
  • Is a measure of your oil's lubricity, or its ability to lubricate your truck's internal moving parts
  • TAN (Total Acid Number): A measure of the buildup of acidic byproducts in your oil, which can lead to corrosion and premature wear of internal metallic components
  • TBN (Total Base Number): A measure of your oil's alkalinity reserve and its ability to neutralize acidic contaminants and prevent corrosion
  • Both TAN and TBN numbers can help to indicate when your oil should be changed

Coolant Analysis

An estimated 50% of all engine failures or poor performance incidents are associated with cooling system problems. For this reason, Peterson uses Caterpillar's S•O•S Coolant Analysis program. S•O•S Coolant Analysis is recommended for all cooling systems, regardless of the type of coolant used.

Coolant requirements for diesel engines are more severe than those of automotive engines. Diesel engines are designed to operate at higher temperatures and higher energy levels than engines in cars or small trucks. Today's heavy diesels produce a tremendous amount of power from a small package. This increases the requirements and demands placed on the cooling system.

Peterson offers a two-level program that indicates a truck's overall cooling system condition and identifies issues with maintenance procedures and operational practices.

  • Up to seven observational parameters and four analytical tests
  • Indicates major problems with coolant and predicts major system problems
  • Results can be used to determine if a Level Two analysis is required
  • Extensive chemical evaluation of coolant and its effects on the system itself
  • Identifies subtle system problems, identifies causes, and prioritizes issues
  • Performed at Caterpillar labs in Peoria, Illinois

Used coolant disposal requirements have become more stringent and expensive. Fluid Analysis customers may extend their coolant drain intervals, or recycle or recondition their coolant, thereby reducing their disposal charges.

Our Laboratory

The Peterson Fluid Lab's interpretation of S•O•S and coolant analysis results are supported by nearly fifty years of database records and experience. Our knowledge of your trucks and their maintenance and operational procedures, combined with our technical expertise, significantly enhances our ability to provide you with sound preventative maintenance advice, not just numbers or graphs.

Abnormal results are automatically sent to product support personnel to advise you on the most appropriate course of action. We build historical data on your fleet as part of a fully-integrated repair and maintenance program.

Our knowledge of International trucks is unmatched, and our direct working relationship with International helps us solve virtually all mechanical issues. Our employees know trucks inside and out, including all the makes and models of your fleet. The resources and experience network available through our organization gives you a huge advantage with any truck in your fleet.
