More Powerful, Reliable Engine Electronics
Cat Tier 4 Final engine electronics are more powerful and robust than ever. Features like an over-foam wiring harness enhance your experience and increase quality and reliability through the most demanding applications.
Next Generation Fuel Systems
Injection timing precisely controls the fuel injection process, which provides more control of combustion for the cleanest, most efficient fuel burn. To maximize your value, Caterpillar engineers specified fuel systems based on the power and performance demands for each engine. The high-pressure common rail fuel system with full electronic injection improves precision and control, reducing soot and boosting the engine’s performance.
Innovative Air Management
Cat Tier 4 Final engines feature innovative air management systems that optimize airflow and enhance power, efficiency, and reliability. A range of simple, reliable turbocharging solutions based on engine size and application allows us to match turbo performance to rated output for high productivity, excellent fuel efficiency, long life, and low operating costs for you.
Cat NOx Reduction System
The Cat NOx Reduction System captures and cools a small quantity of exhaust gas and then routes it back into the combustion chamber to drive down temperatures and reduce NOx emissions. The result of more than a decade of Caterpillar engineering research into this technology is the most reliable system of its type.
Caterpillar designed Tier 4 Interim products with Tier 4 Final standards in mind. By planning ahead, we minimized design changes to deliver the reliability and performance you demand. The aftertreatment solution utilized for Tier 4 Final products is the next evolutionary step for Cat engines with ACERT Technology. To meet the additional 80% reduction in NOx emissions required by Tier 4 Final emission standards, Caterpillar engineers only needed to add one new system to the already proven aftertreatment solution in use, Selective Catalytic Reduction (SCR).
Diesel Exhaust Fluid (DEF)
Cat engines equipped with an SCR system inject DEF into the exhaust to reduce NOx emissions. DEF is a precisely mixed solution of 32.5% high purity chemical grade urea and 67.5% de-ionized water. DEF used in Cat SCR systems must meet the requirements outlined in the International Organization for Standardization (ISO) standard 22241-1. ISO 22241-1 requirements are met by many brands of DEF, including those that carry the AdBlue or API certifications.
An Emissions Solution That Works
The Cat C7.1 ACERT engine meets Tier 4 Final emission standards, and it does so without interrupting your job process. Simply turn the engine on and go to work. It will look for opportunities in your work cycle to regenerate itself, and it will give you plenty of power for the task at hand – all to help keep your owning and operating costs to an absolute minimum.
Fuel Savers That Add Up
The 326F consumes less fuel than the previous series model, and the automatic engine speed control contributes by lowering rpm when the machine doesn’t need it for work. Automatic engine idle shutdown turns the engine off when it’s been idling for more than a specified amount of time that you can set through the monitor. Plus you have a choice of three power modes – high power, standard power, and eco mode. Simply change between modes through the console switch panel to meet the work needs in front of you. Collectively, all of these benefits add up to reduced fuel consumption, reduced exhaust and sound emissions, reduced repair and maintenance costs, and increased engine life for you.
A Cool Design For Any Temperature
A side-by-side cooling system allows you to put the machine to work in extremely hot and cold conditions. The system is completely separated from the engine compartment to reduce noise and heat. Plus it features easy-to-clean cores and an efficient variable-speed fan.
Biodiesel Not A Problem
The C7.1 ACERT engine can run on B20 biodiesel that meets ASTM 6751 standards – all to give you more potential fuel-saving flexibility.
Power to move your material with speed and precision
A Powerful, Efficient Design
When it comes to moving heavy material quickly and efficiently, you need hydraulic horsepower – the type of ground-breaking power the 326F can deliver. Major hydraulic components like pumps and valves are located close together so shorter tubes and lines can be used. This design leads to less friction loss, reduced pressure drops, and more power to the ground for the work you need to get done.
Control Like No Other
Controllability is one of the main attributes of Cat excavators, and one of the key contributors to this is the main control valve. The valve opens slowly when your range of joystick lever movement is small and opens rapidly when movement is high. It puts flow where you need it when you need it, which leads to smoother operation, greater efficiency, and lower fuel consumption.
Auxiliary Hydraulics For Added Versatility
Auxiliary hydraulics give you greater tool versatility so you can take on more work with just one machine, and there are several options from which you can choose. A quick coupler circuit, for example, will allow you to switch from one tool to another in a matter of minutes – all from the comfort and convenience of the cab.
Structures and Optional Undercarriage
Built to work in your tough applications
The 326F is a well-built machine designed to give you a very long service life. The upper frame has mountings made specifically to support the heavy-duty cab; it is also reinforced around key areas that take on stress like the boom foot and skirt. Massive bolts are used to attach the track frames to the body, and additional bolts are used to increase the machine’s digging force, which leads to more productivity for you.
The 326F undercarriage contributes significantly to its outstanding stability and durability. Track shoes, links, rollers, idlers, and final drives are all built with long-lasting, high-tensile-strength steel. Cat Grease Lubricated Track 2 (GLT2) track link protects moving parts by keeping water, debris, and dust out and grease sealed in, which delivers longer wear life and reduced noise when traveling. Optional guide guards help maintain track alignment to improve the machine’s overall performance – whether you’re traveling on a flat, heavy bed of rock or a steep, wet field of mud.
Two counterweight options – 4.0 mt (4.4 t) and 6.75 mt (7.4 t) – are available. Both are built with thick steel plates and reinforced fabrications to make them less susceptible to damage, and both have curved surfaces that match the machine’s sleek, smooth appearance along with integrated housings to help protect the standard rearview camera.
