G3600 Upgrade Kits

Caterpillar first released G3600 engines into the field in 2002, and the A3 has been an active player ever since. With the latest A3 upgrade kit, your engine will experience updated emissions benefits compared to the original A3 model. This kit can be applied at any time but is most cost-effective when applied at a major overhaul (recommended around 100,000 hours). Extend the value of your existing engine today.

Features and Benefits:

• Features advanced combustion technology
  • Updated piston, rings, liner and pre-chamber design
  • Lower emissions through reduced crevice volumes and improved combustion
  • Cuffed liner to reduce risk of carbon deposits
• Emission reduction in GHGs, VOCs, CO₂ and formaldehyde
  • Helps existing engines meet regulatory emissions requirements
• Maintains the same engine maintenance intervals with updated hardware
• Available in both 0.5g/bhp.hr and 0.7g/bhp.hr NOx ratings
• Most cost-effective when applied at in-frame and major overhaul

The Cat A4 Gen 2 kit was designed to keep your engine relevant. This kit is stacked with options, allowing you to customize your kit based on what’s most important to you—whether that’s emission reduction, optional horsepower or increased altitude capabilities. With tested and vetted parts customers have come to trust, the Gen 2 kit extends your investment while delivering on improved emission reductions and durability. Upgrades can be performed at any time but are most cost-effective at a major overhaul (recommended every 100,000 hours).

Features and Benefits:

• Features advanced combustion technology
  • Updated piston, rings, liner and pre-chamber design
  • Lower emissions through reduced crevice volumes and improved combustion
  • Cuffed liner to reduce risk of carbon deposits
• 10% horsepower uprate, optional through engine software rating selection
• Emission reduction in methane, GHGs, VOCs, CO₂ and formaldehyde
  • Helps existing engines meet regulatory emissions requirements
• Need-based customer options
  • Option 1: Emission reduction only, no horsepower increase or turbocharger change
    • Base horsepower offering allows users to take advantage of emissions benefit while maintaining standard compressor match and package layout
  • Option 2: Emission reduction and 10% more horsepower, no turbocharger change
  • Option 3: Emission reduction, 10% more horsepower and increased altitude capability
• Maintains the same engine maintenance intervals with updated hardware
• Available in both 0.3g/bhp.hr and 0.5g/bhp.hr NOx ratings
• Most cost-effective when applied at in-frame and major overhaul
• Base horsepower offering allows users to take advantage of emissions benefit while maintaining standard compressor match and package layout

This kit condenses controls for detonation, engine sensing, ignition and air/fuel ratio into one improved system, giving you improved performance and reliability. Advanced Digital Engine Management (ADEM) 3 monitoring capabilities enable a simplified approach to viewing engine parameters. You can access all types of field program performances from any jobsite, reduce engine wear and maintain consistent control through your operation.

Features & Benefits:

• Single interface for operator using Advisor Panel
• Centralized points to reduce number of electrical faults
• Improvement of wiring harnesses and fewer terminal connections
• Fewer independent control modules
• Closed-loop choke control
• Exhaust temperature sensing
• Easier troubleshooting
• Improved engine protection through individual cylinder detonation control
• Consistent control during light-load operations
• Reliable engine monitoring
• Reduced exhaust emissions and engine wear
• Easily monitor operating engine parameters with remote data access
• Reduced emissions possible when the A3 Gen 2 kit is applied (requires A3 Gen 1 upgrade to apply Gen 2 kit)

Optimize your turbocharger experience with the G3600 Engine Turbocharger VTC to TPS Upgrade Kit. Applicable to ESS or A3 with hydrax engines in the G3600 Series, the conversion from a VTC254 axial flow to the TPS57 radial flow will reduce overall operation cost, as well as improve engine capabilities.

This upgrade reduces owning and operating costs by increasing service intervals and overall uptime while improving altitude and turndown capabilities—a clear example of our ongoing commitment to lead the industry in customer satisfaction by providing the best solutions and customer value.

Features & Benefits:

• Improved software to reduce NOx emissions from 0.7 to 0.5g/hp-hr
• Alignment of service intervals with overhaul schedules
• Higher resistance to fouling
• Lengthened turbocharger lifespan
• This design has proven to be less sensitive to deposits on the turbine wheel caused by impurities in the composition of field gases
• Product is intended to improve overall value by increasing usable power, service life, and decreasing maintenance and repair costs
• Improved altitude and turndown capability
