Caterpillar Introduces New and Updated Products and Technology

Seasons Change and So Do Diesel Fuels



To address the diverse requirements of the global off-highway emissions landscape, Caterpillar has taken a customer’s approach to the new Cat® C9.3B industrial engine. Our customers expect reliability and durability, but they need it from a simpler, lighter package with more power and that’s what we’re giving them.

The 6 cylinder, 9.3-liter engine combines a new high-pressure, common rail fuel system and simplified air, electrical and aftertreatment systems to produce up to 340 kW of power and 2,088 Nm of torque out of a package that is nearly 140 kg lighter than its predecessor.

These changes will deliver many customer benefits including increased performance, improved fuel consumption and exceptional starting capability in cold climates.

These significant system upgrades, which provide added value to OEM customers, build on the core engine, which has been in production since 2011 with more than 46,000 engines, logging more than 150 million hours in real-world off-highway applications. With a proven, reliable core engine and DPF (diesel particulate filter) solution already in place, Caterpillar’s focus for EU Stage V construction customers has been on simplifying design and improving performance.

Along with taking 39% of the aftertreatment packaging size out of the previous design, customers can opt for engine-mounted aftertreatment (EMAT) and full industrial power units (IPU) straight

from the factory.

For the more challenging installations, remote-mounted aftertreatment is available that only requires wiring, coolant and diesel exhaust fluid effects added to the system.

With full engine production planned in the first quarter of 2018, Caterpillar is prepared to meet the needs of Stage V customers.

Genuine Perkins parts available online as perkins.com/shop opens for business

Perkins customers can now buy genuine Perkins parts online after the company’s online shop opened for business.

Targeted at machine owners, rental businesses, repair and engineering shops and mobile service and repair engineers, perkins.com/shop will allow US customers of Perkins engines to buy genuine Perkins parts over the internet.

Perkins.com/shop will initially offer quick, easy access to the most commonly ordered Perkins parts including filters and service kits.

The site is easy to navigate, enabling customers to sort by engine series or product category, and search by part name or part number. Each part has a full description and image, allowing customers to be confident they are ordering the correct part, each and every time.

If a part isn’t currently available to buy through perkins.com/shop then end users will be able to register their interest in the product. This request will be passed on to the local Perkins distributor, who will follow up with the customer on their purchase and other service needs.

The online shop is supported by a new Perkins Regional Parts Distribution Center in Elizabethtown, Kentucky. Parts ordered through the shop will benefit from rapid shipping by air and road, depending on the customer’s preference, direct from the Kentucky parts warehouse.

“We are making significant new investments in our Aftermarket offering, giving end users quick access to genuine Perkins parts, up to date information on their engine and service and support from their local Perkins distributor,” said Aftermarket Director Michael Wright. “The launch of the shop is a key element of our strategy to enhance the service and support millions of Perkins end users already receive from our global network of trained Perkins distributors.

“We know that many of our customers want to be able to easily order competitively priced genuine Perkins parts online. Following today’s launch of perkins.com/shop they will be able to obtain their genuine Perkins parts direct from the manufacturer.”

To support Perkins’ US customers, all parts orders placed on the new perkins.com/shop before July 31, 2017, will benefit from free road delivery.



Caterpillar’s S∙O∙S Services Fluid Analysis and Interpretation

Cat S∙O∙S Services provide information to help you make maintenance decisions, reducing owning and operating costs, and maximize component life. This is a quick and easy program to help your equipment remain productive, and maximize the value of your investment. The two components of S∙O∙S Services are Oil Analysis and Coolant Analysis.

Oil Analysis

The S∙O∙S oil analysis tests have been developed by Caterpillar engineers and chemists. Tests such as Element Analysis, Oil Cleanliness Analysis, and Oil Condition Analysis are examples of the standard tests offered in the S∙O∙S program

Component Wear Rate

Component Wear Rate analysis evaluates the wear taking place inside the lubricated compartment. Your S∙O∙S Analyst uses the results of elemental analysis and particle count tests to evaluate the wear. Trend analysis and proprietary wear tables are then used to determine if wear rates are normal or abnormal. Listed below are some common areas of concern.

  Elevated Test Results Possible Sources
Diesel Engines Iron, chrome

Iron, chrome, aluminum

Lead, aluminum, iron

Sodium, potassium, copper

Silicon greater than aluminum, iron lead

Soot, iron, lead, chrome

Cylinder liners, piston rings

Cylinder liners, piston rings, aluminum piston skirt

Lower rod and main bearings, crankshaft

Coolant contamination

Dirt, cylinder liners, piston rings, bearing overlay

Soot wear on cylinder liners, piston rings, bearings

Powershift Transmissions Silicon, iron

Aluminum, copper, iron

Copper greater than lead or tin

Wet clutch friction material

Torque converter

Bronze bushing and thrust washer

Hydraulic & Steering Systems Iron, chrome

Silicon greater than aluminum, iron, chrome

Cylinder and rod wear

Dirt entry, pump wear, cylinder and rod wear

Differentials & Final Drives Silicon greater than aluminum, iron, chrome, nickel

Copper greater than lead or tin

Dirt entry, gear wear, bearing wear

Bronze bushing or thrust washer


Oil ConditionOil Condition analysis is used to determine if the oil has degraded. Tests are done to look at the viscosity, oxidation, sulfation and nitration of the oil. All lubricated systems risk oxidation damage of the oil. Therefore, it is recommended that oil samples from all compartments be analyzed for oil condition. Your S∙O∙S Analyst uses established guidelines or trend analysis to determine if the oil has reached then end of its useful life.

Oil Contamination

Oil contamination tests are performed to determine if anything harmful has entered the oil. This analysis relies on results from the following tests: elemental analysis, soot, particle count, fuel dilution, water, and coolant. The S∙O∙S Services program has guidelines for the level of contamination allowed in the various compartments of a Cat machine.

Coolant Analysis

Inadequate cooling system maintenance can eventually lead to system problems or even engine failure. S∙O∙S Services offer a two-level Coolant Program to determine if your coolant has the right chemical balance for maximum system protection and cooling efficiency.

Coolant Reporting

Diesel engines are designed to operate at higher temperatures and higher energy levels than in the past. Today’s heavy-duty diesels produce a tremendous amount of power from a small package. Cooling systems have to absorb more heat with smaller cooling systems and less coolant. A cooling system may also be transferring heat away from turbochargers, transmissions, hydraulic systems and other components. In addition, used coolant disposal requirements have become more stringent and expensive. You may be extending coolant drain intervals, recycling coolants or reconditioning coolants to reduce the disposal costs. For all these reasons, S∙O∙S coolant analysis is highly recommended to achieve optimum performance and the full life designed into today’s machines and engines. Four types of analysis are performed during coolant testing; Coolant Type, Boil and Freeze Protection, Coolant Condition, and Contamination.
